Yes you are absolutely correct. But whether the tester has a wide range scan for hydrogen, I may not have a prove for that but I can tell u, am on a project where we are rehabilitating a hydrocarbon plant and each time a hydrocarbon line is aired/opened, the testers triggers and am I usef same tester on my project... Which means this tester is of the industrial standard and approved by the appropriate body for use... So I have got a great level of confidence on this.

On the issue of the period the batteries bubbles, again, yes, I have set my equalization for once every month, so if this is happening and my fan is active, I sure be safe at this period... My major fear was not so much of explosion but the harzard, if any, it poses to life... So with this test result, I think am safe with my batteries in the long corridor within the house as yours..

So I think from your comment, this Concept is safe and it helps... Tha k you for the perimeter provided too anyway!

brother,
it's actually bad practice installing flooded lead acid within your living space. if you have a
verandah, consider moving the batteries there. just build a metal cubicle to shield them from rain.
you can leave the inverter itself within the house. the only downside will be your long cable run from
battery to inverter. better safe than sorry. besides, the corrosive effect of h2 gas may be unnoticeable
initially but over time, your electronics may suffer for it. just my thoughts.

here's wishing everyone on this thread a prosperous new year!

samnaija:


This is very very wrong , and untrue.
Nothing wrong with flooded batteries running pumping machines. I will always say it , if you are currently not using flooded batteries stop trying to make it look has if it is a diseased patient.. stop lying. . period.

my brother, just relax and take it easy. allow them to keep dissing lead acid like it's the most evil
battery chemistry on earth. the fact that somebody used lead acid and got his fingers burnt either due
to ignorance or laxity does not warrant discouraging others from using it.
some of us are still jejely enjoying our lead acid battery banks without stress. if you know, you know.

If the specification sheet is unknown, I think a good CC can help to keep the charging within the limits.
I set my Morningstar Mppt CC absorption at 14.7 but the CC always dropped the limits (target voltage) to 58.07, 58.19 at most with charging current of 19.0A to 20.3A.
I also set float at 53.40 but CC would indicate battery voltage 53.28, target voltage 53.28 as well.

the above charging algorithm is just one out of many salient features that sets morningstar (tristar) cc
head and shoulders above the pack. you can't go wrong with that charge controller. it may appear to
be pricey but it pays off in the long run when you keep using your batteries year after year while others
have changed their battery banks 3x in a row.

merry christmas to all men (and women) of goodwill in the house!

mahkanjuh:


Thanks, does that mean all these binatone plug in AVR is not advisable Kindly suggest then

the plug-ins have their limit. if you really want peace of mind, go for standard avrs that you can see input
and output voltage clearly displayed. that way you'll be sure your electronic equipment is getting the
right voltage needed to function properly.

isangjohnson:
With all the rules duely observed, if lead acid battery can last for 5 to 6 years with lifecycle of about 500 to 800, then lifepo4 may get to 15 years under the same condition with lifecycle of about 2000 to 2500.
I'm waiting to see how many years my tubular will stay alive too. The highest power drawn from my battery is 30%. It's about a year now and I've never top water before.

i got more than 8yrs from my 260ah zenith batteries before replacing them in 2019.
it all boils down to paying attention to the little details. once you get it right abinitio,
every other thing falls into place.

mahkanjuh:
Please house, kindly recommend cheapest AVR for freezer and TV, low budget and efficient. Thanks

be careful bro. in solar as in life, you get what you pay for. that 'cheapest avr' that you're looking for may well be the
reason you will start looking to replace your electronics in no time when the unthinkable happens.
think wise and think smart. just my 2 kobo.

obinnanelson4:
yes boss, i just did...we are on it. Tracking hotbird according to him.

You can't get hotbird with a 60cm dish bro.
At least not in this this part of the globe.

Spy360:

That's what he is saying @ the bolded

Besides what does GeorgeD need Nigconsat for when he uses BUDs

Lolz. You got it bro

Rqw1:




You need to climb up and set your dish correctly. Mine hasn’t shifted for almost a year. Only thing is satview may show sometimes and not show sometimes but you need to always rescan atleast once a week


For those on astra tvc news and tvc entertainment are now on astra 28 maybe temporarily maybe permanently

Brother, i use my motorised 3.2m to track and always finetune for max signals.
Anyway, tanx for the info.
Break the myth!

TOWNJUJU:
Hy guys longest tym
Wow!
Pls is Nicomsat still on?
Or have they changed frequency?

Bros, I hail ooh
NIgcomsat is still available though with unreliable signal at times.

i don't have an idea of current prices but as you know prices of
almost everything has gone up including dishes.

Depending on the construction and materials used, pan can be more rugged than fiber.
It's more resistant to distortion in shape that comes with pulling or pushing during installation and tracking
and is less prone to maintenance.
On the other hand, fiber has better surface finish hence better performance in terms of fringe reception.
However, it is less rugged and prone to shape distortion which results from push and pull (if not handled carefully).
Also, it requires more frequent maintenance like refoiling and surface painting.

tivta:


Silent boss, i hail oh. Do you get hellsat on your 5m dish and like how much would it cost now?

Lolz.
Yeah, I do receive hellasat.
For cost, it depends on the type of dish you want, whether it is pan or fiber.

ceaser:


I'm sorry for reading this message late. Have been away from the site for a while. Also I usually can't access this nairaland mail thingy.

How about proper email on smartintelle at gmail dot com.

thanks. check your email

Spy360:

Welcome home guru. Still waiting for George D and Olenyi

Lolz my brother. I've always been around oh
I only just decided to watch on the side lines while the young ones run the show.
I still have my 5m dish, 3.2m dish and couple of 90cm dishes installed and firing
well. Viva FTA!!!

ceaser:


Sincerely, I can't tell. That's because I have not encountered such CC. But I want to assume that because the light intensity and power directed to the CC from the panels will be gradual as daylight gradually intestifies in the morning, then there is ample time for the CC to adjust itself and probably initiate a protect function.

But perhaps if a large current input is suddenly put on it from a hot midday sun while it is not connected to a battery, then that blue smoke may be produced.

hello bro. kindly check dm. u got mail!

isangjohnson:
Please, maximum of how many months can one mix old LA batteries with the new one?
I know the battery must come from the same manufacturer and must also be the same amps.

my brother,
it's not really advisable to mix old and new lead acid batteries but if you must
(either because of financial constraints or other reasons), it shouldn't be more than
six (6) months apart. and they must be of same spec, same brand (ideally) and try let
them be same year of manufacture.

dollarnaira:


I feel like calling u a name but it is already obvious...wat sort of person are u?

"Lying about?
"No b by force to reply"....
Chai see corporate insult o.

No worder some ppu dont reply to some questions posted here. Your type make others get unduly neglected.

No wahala o.
U try.

Well, I will pass... thanks

there's really no need for name-calling here, i think.
you have to remember that we are all here for one purpose - energy freedom (or so i think)
what myself, samnaija and others are trying to tell up and coming solar enthusiasts is that you know what?
before lithium came onboard, there was lead acid. you don't have to be straight-jacketed into one type of battery chemistry.
you have options.
for all the draw backs of lead acid, namely:
1) it occupies space - not everyone is space constrained (many aspiring renewables enthusiasts might be living in their own
houses, so space is not an issue for them)
2) it is heavier and not easy to carry - again that may not be a deal breaker for many as long as they don't live a nomadic life.
battery banks are not meant to be moved about once they're installed. even the usual battery rotation is done every 12 or 24
months in some instances.
3) the energy density is lesser than lithium - while this may be true, except you plan to use your battery bank to run an
electric vehicle which has a high current draw, this shouldn't be a problem. if your sole aim is to run your house loads, i doubt
there's any domestic appliance that would require such high current draw which your lead acid cannot cope with.
4) dod of 50 (for lead acid) as against 80 or 90 percent (for lithium) - this also is not a challenge for many as proper battery
bank sizing easily takes care of this.
5) it has shorter life span compared to lithium - while this may be true, we have had lead acid banks lasting way beyond their
projected end of service life with proper system sizing and good maintenance practice. my 2v single cell batteries are projected
to last 15yrs by the oem. even if i'm able to get just 10yrs out of them at the end of the day, it would be a major step forward
for lead.

besides all the above, what we would like the newcomers to understand is that despite the much acclaimed drop in price of
lithium compared to lead acid, on a price per watt basis, lead acid is still a cheaper option.
so, if a person who is contemplating going solar is reading all this and all he is seeing is lithium, lithium and he goes to check
the cost of buying a lithium pack, and then throws in the cost of purchasing an appropriate sized bms with all other bells and
whistles, he gets discouraged and walks away thinking, "you know what, solar is too expensive".

over ten years ago, when we started this thread, we were all grateful for the opportunity to learn by building our systems
from scratch using simple, tried and tested methods. they were cheaper but they got the job done. we want newbies to be
given such opportunities too. they don't have to be teleguided into a particular method or battery chemistry. let them try for
themselves and see what works and what does not. that's the beauty of diy and that is overriding aim of this thread.

if we all are objective in our submissions, there would be no need for name calling. and, if we all are able to achieve our
ultimate goal of energy freedom, it would be a win-win for us all.

break the myth! you know you can!!

adrusa:


At this time, lithium battery will still be at about 53V at least.

One thing people don't fully appreciate in lithium chemistry is the improved charging efficiency. Lithium charging efficiency can be as high as 95% or more compared to about 80/85% for lead acid. So, you waste less solar power to charge your lithium batteries and on poor solar days you fill your battery more quickly.

Lithium is just superior to lead acid in every way, people saying otherwise are just being purely dishonest or poorly informed.

my brother,
as you know already resting voltage differs for various battery chemistries: nimh, nicad, lifepo4, lito, etc
the 50.8v for my lead acid battery bank doesn't drop much during the night even under very heavy use, that is why battery
bank sizing matters a lot.
i doubt if mtn, glo, and all other telecoms mast operators including banks will be bothered whether their battery banks
rests at 53v or 56v at sun down provided the batteries are delivering as expected with minimal or no supervision.
we can go on and on about which battery chemistry is superior to the other (on paper) but the bottom line for them
and for me too is value for money spent.

next day instantaneous power captured after noon.

i'm glad battery temperature remained cool at 31 degrees
even with 166a being pumped into its belly

seems august break is around the corner cox the sun is spitting out more juice than ever before.

Magnum = Premium. Never seen it fail

I can only imagine the cost in naira

tanx bro.
that's the price we have to pay just to have light in our houses.

ojeysky:


Till tomorrow if someone show me those 2v 2kah lead acid batteries, I will tell him what they are and why he should avoid them like plague but use lithium instead. Ofcourse he/she still has a personal decision to make.....! However what is annoying is for you to conclude that the action of mine is marketing for some personal gains! It's belittling and embarrassing!

bros, you can choose to avoid them 'like the plague' but try give objective answers to upcoming enthusiasts.
you have a market to sell, no one is saying you shouldn't market what you have but objectivity is the watchword here.
you really don't have to be embarrassed if none of what is posted about marketers here refers to you.

FEGEITOK:


Tell me more about your new baby.

Why this brand?

What are its specs?

lolz. the new baby is actually a magnum ms4348pe inverter. it's the third installation
i'm carrying out since going solar. i needed a back up to my already existing inverter and this
came just in time. sege in benin made this happen. i contacted the regular sources while
searching but to no avail. i guess most vendors no longer stock them because of what's going
on with the economy.

taking it's pride of place.
it couldn't have come at a better time.

...in other news, i had to perform due diligence on this new baby over the past weekend.
thanks to my brother sege in benin for making this possible. this third installment in magnum
is now live and firing beautifully (still under observation).

ojeysky:


There we go again, yes as one of those in that category, I have a few lifepo4 cells for sale, it's only ignorance that can make anyone to believe I ranked lifepo4 cells better than lead acid just for marketing purpose.

again, my brother i think it bears repeating here that no one is saying lead acid is better than lithium.
op saw some 2v batteries and asked an innocent question (which really only needed a simple answer).
but, what did he get in return? instead of a simple answer, peeps jumped out calling 2v single
cells 'obsolete' and making all manner of suggestions as to how lithium has now overtaken lead acid.
a renewables newbie reading all that might be misled, so i was only trying to put the records straight.
nothing more than that.

i decided to use pure copper belts to connect mine in series instead of the thick copper wires that is common
in most telecoms and bank installations.

FEGEITOK:
At almost all exposed ATMs I have seen these batteries, what kind of batteries are they?

In at least one instance, I have seen an installation not for ATM but for an office but with some 200 of these connected together.

these are single cell 2v batteries common with bank ups power rooms and telecoms mast installation.
i have the 2v 2000ah sonnenschein brand installed way back early 2020. it was a deal too good to resist as i got
them at a massive discount as part of 'project leftovers' and looking back, it's turning out to be one of my best
investments so far. unlike lithium, it's an 'install and forget' kind of set up. i don't have to worry about top balancing,
bottom balancing, bms, voltage run-away, etc. the battery bank just keeps delivering with little or no supervision.
and, i guess that's partly the reason why you see them being installed in those locations you mentioned.
you can choose to believe peeps like us who're quietly enjoying their installations without stress or believe those
so heavily invested in lithium that they would jump at every opportunity to discourage the use of lead acid.
obviously, such folks have an agenda. either they have stock they want to offload on you or they have friends who
are vendors they want to help in selling their wares. the choice is yours.
besides, if these batteries are as 'obsolete' as they want you to believe, why are banks, telecoms coys, major hotels
and multinational oil firms still holding on to them as if their life depends on them? need i say more?
