You seems to hate lithium batteries, why? We have a lot of trusted diy pack builders which i have not seen any bad reviews against them he can easily buy from them.There are also lot of fake gel, wet cells or tubular batteries out there. Have you used lithium batteries before? Or do you have any experience against them because i don't understand the hate against them.

bassdow:

Responding late because earlier I choose to ignore BUT somehow, Nairaland's notification reminded i haven't responded to a mention.

See eh, you should read to comprehension.

No where in my comment, did I portray a hate for lithium batteries; except of course you relying on old comments which also, never portrayed such.

Person wey no get enough Money to build / rent standard 1-bedroom apartment, no get business looking for a Mansion all things being equal.

Same way a person who can't easily afford a small (used) Techno phone, would be wasting time pricing a brand new iPhone 20 ProMax.

Imagine say I dey struggle to afford 1-plot of land which cost about 150,000 naira YET you dey advertise another land wey cost Millions to me.

For that guy, if we are to work with such budget, what He needs is

=> 1 or 2 USED Solar panels,

=> 1 USED Tubular or DryCell battery,

=> cheap PWM charge Controller (again him no get business with MPPT whether original or fake),

=> depending on change wey remain, buy small cheap inverter (or use UPS for the time being).

Of course He's got no business with Copper wires. Standard Aluminium cable used by NEPA is good enough.

He's equally got no business with accessories such as racks, etc.

of course na him go rent ladder use connect am himself or find electrician wey go help am while him go dey use Us + Google dey do Question&Answer BECAUSE He still got no business employing services of a professional installer EXCEPT He's lucky enough to find One willing to help for FREE.

Hopefully, you observed I didn't jump into making recommendations to Him, or telling him how his budget is too small and can't go anywhere BUT instead asked to know what He intends powering. Without such information, most responses wouldn't be accurate enough.

The group is meant to HELP, not MILK the hell outta everyOne. All clients needs and budget ain't equal you know

Next time, read to understand. The young man said he is not interested in solar functionality yet and that he is okay charging with grid. Not everyone can use Solar, not because they can't afford to, but because of constraints like landlord refusal, space issues, etc

Also, I am honestly shocked you are advising that he buys a used Tubular battery. Very shocking

Please recommend one for him (or any other regular contributor here) and let him use it normally for 9 months. If he does NOT notice a sharp decline in performance of the battery within this 9 months so much that he considers a replacement, I will give you $50. If he does, then you will give me $50.

Let us have more discussion about this, particularly as regards defining the performance metrics and selecting who would hold the money.

It is time to put your money where your mouth is. I await your response

Hello everyone, both expert contributors and all others.

I have been quietly reading here for some time to learn more. I would be grateful for your help on one or two things.

1. What really is the capacity of a 200ah Lifepo4 battery? We are planning a system, excluding air conditioners, with four 580w Jinko panels and a 7.5kva Inverter; I am confused whether 2 x 200ah Lifepo4 will be enough or whether a single 7.5kwh Lifepo4 battery is necessary as someone has suggested to me.

2. Please advise on whether the Felicity Lifepo4 batteries are reliable.

3. Please advise on whether the Felicity 7.5kva transformer based inverter is reliable.

Many many thanks in advance.

bassdow:


Would be much helpful should you list what appliances you intends powering

Thunderbolt:
Good evening house.

Need some help please.
Trying to get some 555W Jinko solar panels from Fouani at 130k each.
Please does anyone in the house have experience with panels from Fouani?
Wondering if these are genuine products.

bassdow:


About having no intention of using Solar, I probably missed that.

As for buying used Dry / GEL / Tubular batteries, I would say there are both good and bad in the market. Have never bought a USEd Tubular battery for anyOne but as for other types of batteries, I can assure you that there are both good and bad in the market. You just need know how to test.

T[b]hat reminds me, there was a time I sold about 30pcs of Tubular batteries[/b]. They were all as good as New as client was relocating abroad for whatever reason and the installation was less than 1-year in an estate where they sometimes have light. Imagine if you had bought such, you would enjoy it well.

That doesn't mean there ain't refurbished batteries in the market hence reason I said if you know how to test, you should have less issues so please don't be SHOCKed.

See eh, there are lots of people (including installers) buying USEd batteries in the market. Let's not pretend like it doesn't happen.

What about rePackageD batteries, washed and cleaned Solar panels, etc ?

Now if the Guy isn't interested in using Solar panel, like you said, then who says his budget ain't workAble ?

Of course he seems reluctant to state what appliances He intends powering BUT that budget should buy him a used inverter (or UPS depending on his load), and used battery.


In other News, most of my responses in here often are broad to cater for more people than the ASKer hence even my response earlier and NOW ain't meant for just Him and You.

Make people no get 400,000 naira come dey think say e no fit do anything.

Myself, other than my main 2 setUps, most of my auxiliary setUps use rely on USEd batteries which I either buy directly (especially during client upgrades) or when I decommission any.
Only time I suffered bad battery, which was twice, was during my early days of using Solar when I was buying Brand new batteries such as Neptune and the likes before I got to understand those Alaba batteries are fake.

As for your BET, me no get that kind interest. I'm not here to please or impress anyOne. I just talk comment and move

chrisnando:
Good evening house

I recently installed 6 300W panel and I noticed the installer connected all panels in parallel, also he used a 4mm flex instead of 6mm.

A friend of mine came and told me everything the installer did is wrong.

Please could this be true?

You see that you are not to be trusted and people should take your advise as beer parlour gists?

People responded to that brother based on what they have tried, used and trusted, even quoted prices in public domain open to review and criticism, but the only thing you saw in their posts was that they were trying to rip him off. Then you turned around and provided a solution you havent even tried, and without any prices to help him review his budget and make a decision. You even said he should just know how to test the battery before buying. How can he do so when he made it clear from the onset that he is a newbie, and you are not even willing to make a single recommendation to help him

Dont compare buying used solar panels, inverters and even controllers to buying used lead acid or wet cell batteries. It is a world of difference. Na black market, as one of us here would say. You need to be sure of the brand, the source, the history and recite "The Lord is Shepherd" 3 times before taking the plunge. It is not a terrain for newbies and you are simply setting that brother up for monumental failure. Not every budget can get people started on the right foundation, and we should not shy away from advising people to work on their budget.

The other brother asked you why you hate lithium batteries so much, instead of providing a clear and concise response and provide an opportunity for us to learn, you went off the tangent making comparisons no one cares about. You are here again mentioning 300 batteries that you sold in 1985... ...who ask you? How does that extraneous information help us here?

Nobody cares about unverified fables here. This is thread is not for enthusiasts and experienced folks alone, it is also for newbies who plead that we help them avoid the mistakes most of us made when we started our own renewable journey journey. Be kind to them and speak in plain english, providing solutions and recommendations that you have tested, tried and are sure works.

HeavenlyBang:


Sounds to me like you should learn to talk less if you have nothing of direct value to say to someone making an inquiry.

In fact, looking at all your posts, you probably should just learn to talk less all-round.

Hi Experienced folks, you guy are doing a great job. Thank you!

I am a newbie who just found interest in Solar,

Pls I’d like to know which Lithium battery (or any efficient product) and Inverter I can go for with a budget of 350-400k.

There is Nepa Light some days for me to charge the Battery regularly.


NB: Just Lithium Battery and Inverter (No Solar panel)

Thank you!

jonescosmos:
> Yes, wrong Size of cable due to larger current.
> Parallel connection depends on the VOC of your Inverter or Charge Controller.

rhosymedre:


Many thanks for reply.

For now we have decided to exclude air conditioners; so, something like

* 1 medium/large TV e.g. 40 inches and 4 small TVs of 24 inches each
* 1 standard fridge (nothing big) and one small deep freezer
* 1 water pumping machine
* About 8 standing fans (will go for low power consuming fans)
* All electric bulbs in a 5 bedroom house

Thanks again.

bassdow:


Wouldn't mind if you could kindly specify if said installer was gotten from here.

Also you have to change to 6mm as that 4mm is very small. It should get warm now or sooner as the current too much. 6mm ought to be the least.
Wonder who handles cost of the new cables.

Atimes make una dey share quotations here make plenty eyes dey help look am.

Myself almost had issues early this year when I finally dug my borehole. Was supposed to have done it late last years BUT since I wasn't looking to do another geographical survey, and since most don't even do so to begin with, I insisted I would dig the borehole February which is strong dry season. 3 other people who were currently doing there tried to convince Me to do mine also BUT I insisted I would do mine during the dry season.

Even when I was finally ready to do mine, costs have increased BUT I insisted they write me a quotation, indicating all they would be using such as Casing, risers, etc. I even requested for samples which they brought and I rejected it.
They got frustrated but I wasn't about to gamble with 650,000 naira. At end of the day, I showed them the thickness and size of the Casing I wanted and ensured they bought complete and was there the entire time.

because they could buy 12-casings and show you but wont dig deep enough hence they would steal like 2 or more from you. Have seen them do that a couple of times.

Right now, 2 people who did theirs when the cost was about 300,000 naira have all failed. In fact the 2 of them stopped pumping out water, when they tried to increase the riser pipe, they realized the submersible pumping machine was stuck in there. right now, na hose dem dey join come pump water for my compound. Despite the long duration of dry seasons, I was able to not jump pump water for others (outsiders like my neighbors) BUT equally filled all my Tanks and I do have quite a lot of them.

Now they can't talk BUT then, they were sort of against me both the diggers and the neighbors. They would say "Leave am e no go hear. Na wetin e wan do e go do" BUT right now, dem don close mouth and guess what, they can't hold those who dug it.

Difference between I and they was I scrutinized everything even though I had no knowledge. Most things na just common sense. When the Casing (the bigger pipes) has a width like 4-inches or there about, or not thick enough, that spells disaster and when it happens, na the customer go bear the cost.
Imagine if I had followed their advice, including the ones that said "Sir no worry, na our work. No be today we don dey do this work na". Na so money for just loose.

Funny enough, I used a combination of Manual + Hydra drilling machine because they met a very big stone (more than 12-feet long) hence reason I spent that much. Glad I did it sha because right now, it would have cost way way more thanks to condition of the naira.

HeavenlyBang:


4mm for 1800w in parallel is a recipe for disaster.

obitobe:


That 4mm is too small for the level of current that will flow through it. Please call the installer to change the cable to a minium of 6mm

chrisnando:


Thank you, I'm changing the cable tommorow. I was told the panels should be connected 2 each in series after which 3 of the combinations should be in parallel. I don't know if this is right?

HeavenlyBang:


Depends on the vsc of your inverter/charge controller and that of the panels.

AndroBlaze:


First of all, your budget is fine as long as the load you are trying to power is very basic and you have energy saving appliances. Posting it here would help so proper advice can be given.

Also, take the advice of the serious people who are trying to help you here and contact Valto and Linov8 for quotes.

Ithream:


I was discouraged by the prices. Moreover there is light in my area to an extent. Instead I add on top the money go buy land in one area of Ogun state. I’m now a landlord instead of a solarlord.
