my Oga @GeorgeD1, how are your batteries performing now?

my brother, the batteries are performing excellently well.
so far no issues at all. i hope it continues this way for the foreseeable future.

Going to Alaba no be easy thing.. Waste of time, when busbars could have been packed with cells

bro, making diy busbars shouldn't be such a hassle i think.
with just a tape measure and portable drilling machine you can make as
many pieces as you need using a good quality copper belt (like the type used to
install lightning arrestors)
i remember posting some pictures of the ones i made far back when i was installing
my new battery bank.

Hi there. This Solar Water Heaters, how efficient/effective are they? How does it work, Is it direct sunlight that heats the water or there is some kind of electronic heating? What is the average temperature of hot water you get? Near boiling possible? Can you get hot water even at night?
Lastly what is the cost of the one you use?

solar water heaters are majorly of two types: the evacuated tube types and flat plate types.
evacuated tubes are more efficient compared to the flat plate types because they are in direct
contact with the water.
yes, direct sunlight heats the water and no form of electronic heating whatsoever is involved.
(although in a few cases like mine, there is provision for an electric heating coil which you can use
to assist in maintaining water temperature on cold days when the sun output is not that strong)
average temperature can range from anywhere around 50 degrees celcius up to 80 degrees c
depending on your setting and also the weather condition.
you can get hot water all through the day, even at night as the hot water tank serves as a reservoir,
keeping the water hot when the sun goes down.
as for cost, it varies with brand and capacity. but anything between 150k to 650k will do the trick.
it all depends on your pocket.

Buying the Best Inverter
It is best that you gain some knowledge about what to look for in an inverter before buying one. Read on to know some considerations to make before buying an inverter and tips to buy UPS for home:-

#2)Understand how an inverter is different from a home UPS
A home UPS is the same as an inverter, as far as the functionality aspect is concerned—both the devices are used to convert direct current to alternating current which is in turn used as a backup option to generate power. However, the main point of differentiation between an inverter and a UPS—the acronym for Uninterrupted Power Supply—is that there is no time lag between the devices being powered off in the event of a power cut and being powered back on subsequently in case of a home UPS.

However, with devices powered by an inverter, there is a very short period of total blackout when the electricity goes out. It is only for this reason that most computers and laptops in homes and offices are connected by UPSs instead of inverters so as to allow users to save their critical data before powering their machines off.

Now that you know all that there is to buy the perfect inverter, make sure you buy only from reputed manufacturer. Mercury Inverters

bros,
this is no longer an issue with most modern inverters as almost every inverter brand available in the market now has zero transfer
waiting time. what this means is that should there be power failure, it takes almost zero seconds for your inverter to change over
and continue supplying power to your house loads. your computer, tv or fridge wouldn't even know there was public power outage.

Hmm, Metrobox this is not looking too good at all.
Whatever business model you're operating, it's obvious that its not working.
You may consider changing your shipping company or hands off shipping of customers goods entirely.
That will save you over 80 percent of the negative reviews here. Also, how about hiring a PA to take care
of client communication for those times when you're extra busy?
Just thinking aloud...

@George D, and other sat gurus in the house,
There is serious issue here:

Am having one issue like that, there is a particular location, it is only DSTV and mbc 26e you can receive from there, that location stops receiving satelite signal from September 2018, the location is not up to 200 square meters, anything outside that location, Satellite signal will be receivable, note that all satelite signal was receivable in that location before that date, what could be the problem, and how to solve it,
I noticed that any TP that is below 12 ghz cannot be received there.

@graphicicon,
Sorry I'm just seeing your post. I think you might need to check for wifi signals or microwave around that neighborhood.
It's most likely there's a telecoms mast close by or an ISP has mounted a microwave link within the vicinity.
Whichever it is, just move your dish some distance from the original installation spot.
Also, you can consider using WIMAX friendly lnbs like single solution C band lnb. It's a little expensive but worth it.

Israelicc:
I think we should give him his due credit. The route he took is quite a thing.@totalgreen01 took the time to ensure that his project is also safe for use by introducing fuses into the setup. The bank has everything a lithium battery setup should have (BMS, fuses, indicators etc). The bros tried in my own opinion.

bro, u're very much on point. totalgreen is a veteran when it comes to renewables.
he surely knows what he's doing. it's not today he's been working on and perfecting this craft.
kudos to him.

Hello Metrobox,
Thanks for the prompt manner you handled my Ebay order. I came here and went through your thread,

Hello WaytoGo, don't be confused.

Satellite signals behave like light rays, the dish face the satellite and the signals are reflected onto the LNB. Picture 1

Satellite signals also behave same as light by obeying the laws of reflection. (You first question)
The law of reflection states that when a ray of light reflects off a surface, the angle of incidence is equal to the angle of reflection. Picture 2.

To Install multi LNB on a single satellite dish.

Now when you move a dish away from a satellite, you increase the angle of incidence of the satellite signal, the angle of reflection also increases
In a nutshell, if a satellite signal comes from left of the dish, you search for the reflected signal on the right part of the dish. the same is applicable from top, i.e. you get Belintersat 1 at 51.5°E and moves the dish to NigComSat 1R at 42.5°E you have moved the dish up, which has increased the angle of incidence in which case you need to place your LNB above NigComSat 1R at 42.5°E to search for Belintersat 1 at 51.5°E to receive the signal, not below .

Picture 3.

microgiant,
Well done bro. Nice illustrations too.

earthrealm:


With the rise of decent hybrids, i forsee a sharp decline in demand for stand alone charge controllers

bro, i wouldn't jump to such conclusions yet if i were you.

stand alone charge controllers are still way ahead of their hybrid siblings in terms of performance and features and
those that value battery longevity will choose them over hybrids any day and anytime.

personally, i don't think i would be singing such high praises of my recently sold off zenith batteries if my cc had
been a hybrid.

SIONKPO1:
okay,below is the pix

OK. I see digitman has already done justice to this.
Try re-aligning the dish with those TPs he gave you and your signals will be restored.
And by the way, the guy that installed that dish didn't do a good job securing it firmly
to the roof below.

SIONKPO1:

Okay,but the channels did use to show before(last week),but it just stopped showing and when I did blindscan none of them(MBC) came up but I got telemaroc,medi1 etc

A picture of your set up as it is presently will help in giving you solution.
Pls upload your dish pix and especially the lnb.
Although I suspect seriously that lnb has shifted from its original position.

contease:
Goodevening everyone,


Meanwhile i have something I did like to share. I think this will be for the gurus to educate us more and if it's right, newbies like me can pick something new as to improvice too...

Firstly, I would like to make it clear that my steps or methodology are not conventional and I had to try this due to, majorly, financial constraints, and in a bid to try something out of the ordinary.

We all know how the inverter systems works as a proper setup which is:

Connect the PVs to a CC, then the CC to the batteries, the inverter to the batteries then house load to the inverter.

Again, for financial constraints and in bid to try sometin new, I decided to eliminate the PV by using a small automatic battery charger that outputs 12amp charge. (see bellow image of the charger and my bts inverter)

SETUP:
With the batteries (unconventional batteries) connected to the inverter, I then connected the charger to the AC output of the inverter.

With grid, the inverter is supplying the house and charging the batteries while the charger is also getting AC from the inverter and juicing the batteries at its own automated charge. Meaning, as the battery is getting full, it's charging amp is reduced from 12amp through till 1amp then cuts off (this charge has CC, CV, FC and TL charge stages whick I don't know what they stand for as they are not writing on the manual). Sometimes the inverter Cuts off charging first and other times the charger.

Without grid, the inverter sucks from the battery to feed the house and also feeds the charger which inturn feeds the batteries like a loop.

What I have gained doing this is more online time. Eg. If I was getting xy time without the charger, now I get an additional z time meaning I now get xyz live time.

I have only used this setup for precisely 9days and am still monitoring carefully to know if there will be any consequences... DISCLAIMER: PLEASE DO NOT TRY THIS AT HOME IF YOU CAN NOT MANAGE IT OR YOU ARE NOT AT HOME TO EXTINGUISH INCASE OF FIRE! .

While, I would appreciate gurus to please imagine this setup and let's know ur thoughts. Though GeorgeD1 and I have been discussing offline about this and he disagrees with me on some of my planned actions but because am on ground to monitor, I decided to give it a shoot... After all, it's all about DIY... Lol

[/i]

brother, our discussions have been very engaging and robust. you always come across as someone willing to try
whatever it takes to pull ahead in the quest for energy freedom. so, i'm not surprised you eventually went ahead to
implement your idea (despite my misgivings). however, as you can see from niyi, ceaser and others here, it might not
really be the best. all the same i understand why you had to do it.
going forward though, you have to think seriously around getting a separate cc and solar panels as an external
reliable charging source. there are quite a few members here disposing old panels and fairly used cc and you
might be able to land a good deal soon if you keep your eyes open.
once again, all the best.

So those of us that shared our experiences on both battery chemistries were not giving facts abi. Isorite o

lolz! bro! edited to include you as one of our prominent, eminent lithium ambassadors!!

all,
over the past two weeks, we have had a lot of interesting argument both for and against lead acid and
lithium. and like that flier earthrealm posted a few pages back,

https://www.nairaland.com/390522/solar-energy-complement-fta/878#95271112

the aim of an argument or discussion is not victory at all cost but to bring out facts and enrich our knowledge.
we all win when we learn from each other. and on that note i like to commend all who have taken part in this discourse so far.
it may have seemed heated at a point but that cannot be avoided. it is what happens when intellectuals rub minds together.
looking back, it's amazing how a simple, innocent question from babniyen,

https://www.nairaland.com/390522/solar-energy-complement-fta/871#94990932

could have triggered a wide ranging discourse on the superiority or otherwise of one battery chemistry over the other.
have we seen the end of the battery 'wars'? not by any stretch of the imagination. today it is lead vs lithium. tomorrow
might be lithium vs some other emerging battery chemistry and the list goes on.

let's keep the conversation healthy and together we will all achieve victory over darkness.

break the myth! dispel the belief!

adrusa:


Very funny. I think you have similar complex with @GeorgeD1. You think because you paid top dollar for some proprietary system, it must be better than the cheaper more open source option! You are very wrong.

Let me tell you what you may be aware of. I have a few network routers in my house; Linksys, TP-Link, Netgear, D-Link and Mikrotik. Aside the Mikrotik, the first thing I did to the other ones was to get rid of the factory firmwares that came with them and flash open source firmwares; DD-WRT, Gargoyle or OpenWRT. Yes, I got rid of the firmware developed with R& financial muscle of big network vendors like Linksys (Cisco and Belkin at various times) and put open source firmware developed by a bunch of small but very talented people working mostly for free.

Same with my expensive Samsung phones. I use open source modification I got from XDA from the likes of Dr.Ketan, an Indian ENT Surgeon. Yes, I abandoned Samsung's R& software for something developed by an hobbyist working at home in his spare time. My major grouse with iPad and iPhones is their ultra-proprietary nature. Some think that they are better, but certainly not in my book. That is why I'm a fan of android phones.

@GeoargeD1 believed that his heavy investment in LeadAcid Batteries makes them better than Lithium, while you think that your investment in PylonTech makes your battery better than ours. That may be true, but it has absolutely nothing to do with all you said above.

My personal experience is that non-proprietary systems tend to be more robust, less restrictive and better maintained than proprietary commercial systems. They also get better support from DIY community. It is the same reason why Linux is a more robust and stable production software than Windows. Of course, one of the first thing I did with my Felicity Lithium was to replace its BMS with ANT BMS. The Felicity BMS looks better and bigger, but I have absolutely no control over it. If I buy PylonTech, I will certainly change its BMS to this "DIY BMS" you disrespect so much because it didn't cost a arm and a leg. Things are not necessarily bad because they are DIY, or cheap, indeed, many times they are better, because they are more open and less restrictive.

bro, i don't know where you got that 'complex' thing from but i certainly don't have one.
yes i invested heavily on lead acid but that was because i was crazily impressed with what my previous bank
gave me - and that in spite of all the hues and cries going on here against lead. so my thought was, if i could get
this kind of good performance from a supposedly no-name battery brand, what if i get something more reputable
as a replacement? and with that consideration, the sonnenschein battery deal was a no-brainer to me. anybody
in my shoes would do exactly the same. it was a deal too good to resist.

would i have jumped at the offer the way i did if i had been having a hard time with my zeniths? i think not.
were they necessarily that expensive despite being a renowned brand? of course not. even though for a similar amount
i could have splashed out on a lesser sized lithium bank, my overriding argument goes beyond just price.

on a cost/ah basis, lead acid is clearly ahead until such a time when lithium becomes mainstream but on an energy
efficiency basis, vis charge and discharge cycles, lithium rules. still it doesn't make either one superior to the other.
each battery chemistry has its place.

ojeysky:


I actually think it is you who continue to make people feel lithium is some scary and deceptive thing, on reasons best known to you. If it was not better Niyi will not continue to accumulate(for business reasons or otherwise) and those who use it will not share their experiences (good or bad). It's no brainer that lithium is a superior chemistry to LA any day any time but that still doesn't mean that both chemistries won't appeal to us differently. Why you see experience sharing as being trickish is what beats my imagination, isn't that what this thread is about.

In my actual professional world it's over a decade now that operators are being adviced to deploy IPv6 but up till now IPv4 dominates, the difference however is that the number of networks running IPv6 now compared to a decade ago has increased significantly and it's only a matter of time before IPv4 will eventually be obsolete and relegated.

Ultimately the choice remains with each individual to either deploy the present technology with future relevance in mind or be caught unprepared.

brother, nobody is making anybody scared of anything. if you read my posts correctly what i was emphasizing on was the need to
bare all and let the facts be known and i'm happy that cue was taken on by no other eminent personality than niyi, saipro and yourself
the able ojeysky

truthbetold22:
@georged1,

I think your attempt to prove that lead acid trumps lithium is bais at best. Lithium technology has come a long way and beats lead acid in every department. Everyone keeps referring to your previous LA bank but that bank has a lot of untold stories. For one, I remember you had 800ah of battery capacity. You also had over 40kw of solar panels if I am not mistaking. You have also mentioned that you rarely cycle more than 30% daily. At 30% dod, most good LA batteries will easily do what the Zeniths did. It wasn't special. What you must note is that to get away with such low dod, you need to have a really large bank which you did and a large array too. For the average enthusiast, that is an impossibility as the initial outlay would be outrageous. You only got that longevity due to your use of the battery. If you look at the cycle life graphs of lead acids, you would find that there is a significant difference between discharging to 70% vs discharging to 50%. Are you now saying we should all get 800ah banks and 40kw panel capacity to be able to enjoy longevity with our batteries?

I ll summarize as follows

1- Firstly, even the second class lithium batteries advertise 3000 cycles at 80% dod with a 2 year warranty. That is something only the very best lead acid batteries can dream of. That is almost 10 years of battery usage if you do a cycle a day. Regular lead acids cap out in a couple of years at 50% DOD if you are lucky. Don't tell me, I have gone through a few banks.

2- Considering how bad our weather can be in the southern part of Nigeria coupled with struggling to get 3-4 hours of sunshine daily, it is a no brainer to use lithium which can charge at 1c should need be and get your battery to full capacity as quickly as possible especially in the raining season unlike with a lead acid battery that takes forever to charge at 0.1c and then has to do all the absorption thing. This is very important for people who rarely have grid electricity and/or have a small bank.

3- Lithium chemistry is way more efficient than lead acid and looses less energy to the storage and discharge process which means you have access to more energy per ah.

4- As a result of 4 above, you can power heavy appliances off relatively small banks. Something that would only be a dream with lead acid.

That you haven't embraced lithium doesn't make your lead acid bank better. The world is evolving and if you choose to remain with old technology, you may have your reasons. However, do not try to prove on a public forum that lithium is all hype. There are more than 15 active members on this thread who have made the switch to lithium and not 1 has anything negative to say about it 1 year down the line so what is your point exactly? People got burnt with lead acid for many years until the best brands were identified. Heck, people are still getting burnt even today so why assume lithium will burn you?

There is a reason phones and laptops use lithium and 10 years after, the batteries still work. Stick with your lead acid if you want but your arguments are obsolete.
Lead acid can never be better than lithium. Initial outlay, yes. Satisfaction over time, a BIG no. It is no longer a function of whatever works for you. Even though it works for you, you should be gracious enough to accept that there is something better out there. That I drive a Toyota Corolla and it works perfectly for me doesn't make the car better than a Lamborghini.

Thank you all.

thanks for your analysis bro. you made a lot of valid points but missed out on a few.
my zeniths didn't last that long only because i had an oversized bank and solar array. it was more
a combination of factors too numerous to enumerate here. go down memory lane and we have heard
sorry tales from peeps and even companies who installed large battery banks and had them fail
woefully within the first or second year.

my reference to people getting their fingers burnt resonates both with lead acid and lithium.
i will encourage you to read up that website that earthrealm posted a few pages back and you will
understand where i'm coming from. be it lead acid, lithium or any other battery chemistry, if you jump
into it ill-informed you will certainly pay a huge price not only in terms of loss of investment but also at
risk to your own personal safety.

i repeat that no one battery chemistry can claim to be better than the other. each has its own place.
if i'm using lead acid and it is delivering exactly the performance i expect, why change a winning team?
on the other hand, if for any reason lead fails me tomorrow, why stick with something that's not working?

the goal here is energy freedom and as long as what you're using is setting you on the path to achieving
that aim, i would say go for it. it's as simple as that.

NiyiOmoIyunade:
I can speak to the complexity of Lithium vs lead acid.

There is so much one needs to get right else a huge investment would go down the drain.

I use a popular and well reviewed battery - PylonTech. You are told you can add new batteries to the bank at will. In reality it is not so straight.

I got my first set of 8 in November 2019 and it was easy peasy until I added the 2nd set of 8 in June 2020. The bottom most battery refused to catch up with the others in charge and discharge and kept throwing over voltage and over temperature alarms. I would have lost that battery had I not gained admin access to the BMS and recalibrated values to allow the module recover and catchup with the others. The cells in that module were not perfectly matched as the others and kept drifting.

Now I added 4 new bricks this October and the BMS software version is higher than the old bricks - the result - combined BMS throttled my maximum charge current to about 300A - 15kw instead of the design 500A/26kw. I am now current limited to 15kw by the battery even though I have a 20kw PV array. I have yet to figure that one out as the BMS tells the Victron chargers what to do per time and if you insert a new value, it just gets overwritten 30 seconds or so later.

The next big myth is discharge rates - you will be told you can run at 1C with no issues - this is true but only within a SoC range e.g 20% to 100% - once you drain battery below 20%, you may find the BMS cutting large loads to protect the circuitry and cells - ditto for charge rates - try filling a 48v 1000Ah battery at 1C and you see cell temperatures jump up fast - this is not good for long term health so in my case I capped my charge current at 0.3C - getting from 20% to 100% within 3 hours on a 48v 1000Ah bank is good enough performance for me.

Really there are many things to consider and get right especially for large systems. I routinely see my BMV 500A shunt running hot when passing like 18kw of energy. I see up to 50degC on shunt and 40degC on bus bars so I am in the market now for 1000A shunt and even thicker bars than I already have. Even my 600A continuous rated Blue Sea Systems DC isolator runs hot when passing 18kw of energy. With the energy density of Lithium, a short or failure in the system could be catastrophic indeed.

On the plus side you get early warning of issues especially if the BMS talks to you. This is one strong advantage over lead acid. Because I can see every detail about every cell with the Texas instruments chip BMS bundled with the Pylons, you can take early corrective action. Again this info is not available plain text, a solid knowledge of cable pinouts, serial/RS485/CANBUS communications and many other esoteric skills are needed to interact with the BMS and adjust operating parameters if required

nice one niyi. at least we finally begin to see some down to earth details popping up far from the glossy narratives
we been hitherto fed with.
your admissions tally completely with what that rod guy was trying to explain in his website while also mentioning
your battery type - pylontech.
when we lay the facts bare for all to see, discerning peeps are able to make informed decisions without feeling
tricked into venturing into something they thought was all frills and thrills.

earthrealm:


This article is a good read, and tackles all aspects of the lifepo4 vs lead acid debate..
I must warn you, its a long read ..

Peeps averse to long reads can scroll to midway and read only the pros and cons of Lifepo4 battery bank.

https://marinehowto.com/lifepo4-batteries-on-boats/

tanx for the link bro. i've spent quite some time purring over the contents and its really interesting.
this rod guy leaves nothing to the imagination and seems to bare it all. the quote below was lifted
directly from the site and if this doesn't mean anything to anyone then nothing else will:

"WARNING / DIY BUILDS:

I do not believe LiFePO4 is ready for mass DIY prime time builds. Read with caution,
and especially focus on the things that you don’t want to hear rather than only what you want to hear.
Once you are done reading this, and it makes sense to you, then please spend another few months reading
everything you can including every single LiFePO4 white paper you can get your hands on.

While this article is meant to be very basic, and get you a basic level of understanding of LFP,
the science side of it matters too. We strongly recommend that you also read Eric Bretscher’s site for
the science side of LFP:

Nordkyn Design LiFePO4

With this article, and Eric’s information, you’ll be well on your way to understanding how to use a LiFePo4
marine system without ruining it prematurely.

Wallet Burns:
Since opening this article to the public we have now had what I consider a rather high number of LiFePO4
owners contact us who’ve ruined LiFePo4 batteries (not all marine based). In almost all of these cases of
destroyed LiFePO4 batteries the resounding tone I hear come through is;

“But Rod, People on the internet made it sound so easy?“

Hey, lets face it, everyone gets excited with their new toys, and likes to talk about them, but we urge
you to please do more research. In other-words, don’t jump to conclusions based on scant information, where
large sums of money are involved."

adrusa:


This so-called "war" was started by your attempt to run down lithium. We were only correcting your wrong assertions about it. We all started with Lead Acid and I still have a lead acid bank that I run side by side with lithium. Lithium is the better option if cash is not a problem. That is not even open for debate except for people who do not follow progress of renewable energy. Lithium is all the rage at the moment. Just check international solar fora if in doubt. Anyone who can maintain lead acid can certainly maintain lithium. All that is required is to set proper charging parameters, just like it is required for lead acid.

For newbies, we cannot overstate it, if you have the cash go lithium right from the gate. That is where many people will be in 5-10 years time. All those urging you to do lead acid, would have moved. And like they say, misers pay twice. Some of us started our solar journeys with cheapos solar panels (e.g. no name brand), charge controller (e.g. phocus pwm), inverter (eg. no name chinese inverters) before we realised the benefits of paying top money for good, tested and trusted brands like Victron, Outback etc. If you have the means, go big, go lithium, the only thing to fear about lithium is fair itself. I have tasted both words substantially. There is nothing anyone can tell me about lead acid batteries that I have not experienced. From huge trailer batteries (my very first batteries) to Trojan premium flooded batteries (my current lead acid bank).

If you don't have the means, good lead acid will still serve you, just not as good as lithium.

By the way, I was banned for my last lengthy post. I have no idea why. My first time of experiencing the dreaded Nairaland erratic banning bots. I hope I wont be banned for this.

lolz bro! i guess you may need to read my post all over again because you totally missed the point.
nobody started any war (contrary to your assertions) and if engaging in intellectual discourse is considered a "war"
(in your opinion) then i guess it's a good "war". meanwhile, i'm sure the newbies are seriously taking note and they
surely are the real beneficiaries from all the back and forth exchanges.
having said that, i repeat my stand that both lithium and lead acid have their place (in case you might not be so
inclined to go over my past submissions), so no one battery chemistry is better than the other.
what works, works and what doesn't work doesn't work. most peeps today still use lead acid because it works for
them. i mean, think about it, why change a winning team? the fact that some people dabbled into it ill-informed
and got their fingers burnt doesn't mean we should condemn lead acid and begin to play up the lithium card as
the magical solution for our storage problems. any attempt to gloss over the negatives will mean folks might likely
repeat whatever mistakes they made with lead acid that pushed them into looking for salvation in a new battery
chemistry. and the chase goes on and on with many getting disillusioned with renewables in the end.
once again, my take: let's put things in their proper perspective so that would-be enthusiasts will have a fair idea
what they are getting themselves into. i'm sure that's not too much to ask for?

funshyboi:

Yes you’re right it’s those INEC battery and possibly it lasted because I’ve been charging it with electricity and using it for just laptops until now
Trust me I’ve gone tru the manual times without number the English there is not explanatory at all.

I’ve long pressed the buttons too but maybe I will still do for a longer time Again

Please can I inbox you?

bro, you might have to consider changing out that cc if you really want to charge your battery with solar.
i'm thinking that cc may be one of those rudimentary types that don't have any user adjustable setting
and this could be bad news for your batteries.

Saipro:

As I said previously, the war isn't against lithium. Lithium proponents keep thinking old school lead dudes are having inertia or fear-of-the-unknkown/FUD issues. That's an unkind thing to say. We're all interested in the latest gizmos which work as well as the ease of life which advancements in technology bring. If it works for me, it works. If it doesn't, it doesn't. Incidentally, some of the loudest voices for lead have either previously used lithium or secretly have smaller banks of lithium deliberately undeclared. Some don't want to be dragged into a mudfest thus opted to remain silent. I know some of them.

And that's what GeorgeD1 is saying. Get what works for you. I had the LiFePO4 some time before it became a hype yet continued using lead acid for reason of it satisfying the purposes I had in mind. Should lead acid fail me, I'll change in an instant. I have all the space I need and about 5kWp of solar panels sitting in my store. Coulombic efficiency is irrelevant to me (though that's wrong). See, that's what matters right there - application.


Until then, each to his own tents. There is no war; there hasn't been and there will not be.

well done bro. you took the words right out of my mouth. nobody is fighting anybody on here. just pure
intellectual discourse.
my concern mainly though is we should all try to put things in their proper perspective.
(and i must say you certainly have done a better job than myself in putting your own personal usage experience
to bear on the various battery chemistry types in question)
unknown to us, a lot of newbies and would-be solar enthusiasts do visit this thread and make decisions based
on what they read. it would really be unfair to them if we paint an unnecessarily glossy image of lithium only
for them to dabble into it before realizing things were not nearly as rosy as they thought.

we could go on and on with the whole lithium vs lead acid debate but then what's the point?
what works, works and what doesn't work doesn't work. it's as simple as that.
on paper my 260ah zenith batteries were not supposed to last beyond 2yrs. or 4 at most (with careful usage).
but here i was using them for over 7yrs and at a point i even became confused as to whether they were
really lead acid or some other battery chemistry sold off mistakenly to me as such.
as for deception, i think if anyone is trying to deceive anybody it certainly wouldn't be the lead acid camp but
those on lithium. why would a company that has been in business over 50yrs like exide, hoppeke, trojan, etc
risk their reputation by putting a 15yrs label on a product they know would go bust under 3 or 4 years? that
would be suicidal to say the least. lithium on the other hand still remains a grey field and largely untested until
recently. so when you hear glowing number of promised cycles, better be cautious because nobody can really
show proof that it can live up to that.
lithium becomes a hype (in my opinion) when proponents try to play up its supposedly superior qualities
while downplaying the negatives. at least in this thread, i see a pattern emerging where it would seem like if
you're still using lead acid you're regarded as not sophisticated or not moving with the times. how wrong can
that be? no wonder someone is comparing lithium and lead acid to manual vs automatic cars! lolz
truth is that each battery chemistry have their place. depending on its application, none is superior to the other.
crucially, on a price to amp/hr basis and ease of deployment vs maintenance, lead acid wins hands down. it is the
reason why you won't find telecoms base stations or banks installing lithium (yet) as their primary battery banks.
they rather go for trusted and tested technology which don't need tinkering with before it can perform.
that said, nobody is ignoring lithium. far from it. personally i'm all for new technology, never against innovation.
i look forward to a time when lithium becomes mainstream just like lead acid. from li-ion to lifepo4 and now lito.
it can only get better. but anyone thinking lead acid will go away anytime soon better brace up and get ready
to be disappointed!

Good evening guys,

I’m a little bit worried about my LifePo4 battery that last 5 hours when I Do charge it with electricity. But when I use solar panel it doesn’t last up to 2hours.

Even The controller shows It that That the panel stops charging battery at 95% Instead of it to be at 100%

kiekie1 eleojo23 wilmaria14 GeorgeD1 ceaser your vast experience and suggestions are needed.

you got to check your cc settings. obviously your charge controller is not charging your batteries to full capacity hence
the sharp drop in back up hours as compared to when charged with public utility using your inverter charging
function. it could also be you may need to increase your solar array.

i really get amused when i see these postulations on paper how 50% dod of lead acid should be equal to
80% dod of lithium. even now we are seeing weirder assumptions of 30% being equal to 80% lead acid!
i guess its fine when we do these abstract projections but we all know that in the real world things do
turn out differently.
having said that, i think the main attraction for lithium remains its expected longevity due to the possible
many cycles as compared to lead acid. however, if my recent experience with my zenith batteries is anything
to go by, it means lead acid when properly managed can also give many years of use without conking out
(by the way, my guy who bought the used zeniths from me has had nothing but praise for their
outstanding performance). quite remarkable given they already served me for 7 years plus as at the time i
replaced them and sold them off.
then, enter the hoppeckes, the exides, the sonnenscheins which promise up to 15 years of quality backup
for their lead acid batteries and the attraction for lithium further takes a dive.
while the lithium jingle continues unabated, my candid advice to newbies is to be wary of bogus promises
from sellers intent on offloading their lithium wares on them. they will come up with several clever marketing
tactics all intended to make a sale.
if you're just starting off on the renewables journey, you will do well to stick with tried and tested products of
which lead acid batteries is one example. you really don't need to dabble into lithium where you have to
contend with a whole gamut of bos devices including bms, bmv, cell balancers, special chargers with lithium
profile, inverters which have to be tinkered with in order to work with lithium, etc.
the world is already complex as it is, you don't need to complicate things further just because you want to
provide reliable uninterrupted power for your household.
go with what works out of the box. a word is enough...
