TechGeek777:


Can you please mention the guy's name?

BlueCross in Eleyele Ibadan

Oshomo12:


Valto's cells capacity checks out. I have bought and tested his cells to full capacity.

I am trying to believe so…I am in talk with him for 24v 280Ah

Obnoxious2001:
The way this thread dey take drag down lead batteries .

Not everyone starting up in solar can afford to buy lithium battery at the initial stage.

Take it or leave it, lead acid batteries has more economical value.
It's cheaper, if it has served you finish, it can be recycled and you get your small cash back.

Tubular is flooding Nigerian market because they are cheaper.
Mind you depending on how you use your lead battery, they can do up to 5yrs

Before you sell 1 lithium who dey sell tubular don sell 15pcs
There is a market they are aimed for.

You spoke well . I don't know why some people are hell bent or having sleepness night over lead acid.

The truth it is cheaper and serves its purpose. I have been using tubular batteries for 4years plus and no issues. Majority of people are on tubular for one reason it is affordable and carries its weight.

You go to an average Nigerian home it is lead acid, it serves its purpose especially in this difficult times. Am sure I will keep running my tubular till a different technology apart from lithium comes along. (Likely get another 5 to 6 years from those bad ass batteries).

Likely then, i will jump on that one, then those that are currently on lithium i will castigate them also . And ask the question wetin you still they do with lithium....... technology has phases .

Drgreatone:

What's the size of ur inverter and configuration/size of ur s? The 63amps might still serve u. This ur Schneider is looking different to what I am used to.

5kva 48v hybrid.. with inbuilt charger
4 * 12v 200ah batteries
8 * 300w s (everything bought new, but we were later told the s are actually rated lower in watts but reportedly manipulated by the vendors)

The Shneider DC circuit breaker could be fake (pretty sure of that)

Installation is nearly 3 years now, still running, but the batteries don't seem to be getting enough charge; and we are not sure whether this is due to the s not performing optimally or something to do with the DC circuit breaker

Oshomo12:


What's the size of solar s on this breaker?
This is an AC breaker, hope I am seeing well. This is not rated for DC

Really?

Solar s are 300w * 8

Valto:
ofcourse , i use 2packs personally. 48v 280ah and 48v 300ah, that makes them 48v 580ah

Can two of your 24v 300ah batteries be parralled to give 48v 600ah or how does this work with lithium battery?

Valto:
ofcourse , i use 2packs personally. 48v 280ah and 48v 300ah, that makes them 48v 580ah

Nice, this is what I needed clarity on.

Good morning, which brand of battery are you using?

There will be no need to castigate anyone because some of those guys using lithium phosphate today may get there before you..
As I earlier said, everything in life has to do with choice.
It's wrong to condemn people's choice.... What works for Mr A may not work for Mr B.
Whenever I designed systems for my customers, I gave them the two battery chemistry to make a choice, even though I'm not selling lead acid batteries.
There are some lead acid batteries (12v 200ah/220ah) that are currently sold within the range of 300k to 310k and they will serve the purpose at a given period.
There are also lithium phosphates of the same capacity and the same amount and they will serve the purpose at a given period as well.
It's all about the market flexibility, the individual budget and what they aim to achieve.

No, its not advisable to series lithium battery pack... parallel connection means connecting red - red n black - black while maintaining its natural voltage of either 12v, 24v or 48v

Morning if you read this thread from the beginning, you will notice the change in battery technology in Nigeria.

About 10 to 12 years ago , generally Nigerians were using gel maintenance free batteries, while those that have money used agm batteries.

I was stuck with gel batteries. Agm
Of course was better but cost more.

All of a sudden flooded batteries became the new baby ( trojan and one American battery ).
Of course new battery tech will initially cost someone a kidney to get.

But a few of us on this forum were on this new battery (flooded batteries) , and we all dreamed to acquire these batteries.

All of a sudden tubular batteries walks in with a cheaper version of flooded batteries. I was on my last lap of my maintenance free batteries.

It was far cheaper than the original flooded, but same tech. I ed tubular immediately and so did most nigerians leaving behind gel batteries , agm and even original flooded batteries.

Then the new battery tech in Nigeria, lithium far better than original flooded, agm and tubular batteries. But like i mentioned earlier new tech wil cost an arm , a leg with even kidney this time. I am very confident a cheaper version of lithium will come along soon. And nigerians will do the needful and migrate. Till then we go manage our tubular batteries. My respect goes to those already on lithium it is not an easy fit to achieve.. someone has to break in new technology.

mctfopt:


In small capacity say under 6 batteries, I see nothing wrong too. But if you really need energy to require up to 20, that's where I'll recommend going lithium. I've seen cases of this type of system dying way before their time due to issue mostly related to charging. Most of these large banks like this miss out on proper charging. Going the lithium route would've been a better alternative when you need energy this huge.

Boss, even with large bank, lead acid battery can still be properly charged and managed very well.
Once you get the basic things right, every other thing takes care of itself.
This issue of comparing LA battery with the Lfp has been discussed extensively some years back in this forum.
George_D has large LA battery bank and he has used it for about 6 years then. Maybe, it's up to 10 years now.
He's one of the founder of this forum and I really learned from his knowledge and I'll always appreciate him.

EduTechTainMent:
Open box Sachet inverter up for sale.

Specs:
2000W 24V

Reason for selling:
Couldn't be used for the project I planned on using it for. Had to settle for a transformer based inverter.

Duration of use:
Not used at all. Just tested for some minutes. It was waybilled to me by @valto and I took delivery of it 2 days ago (23rd March 2024) . Installation was attempted today (25th March 2024).

Asking price:
87k

Hit me up if you are interested.

Still available for sale guys.

TechGeek777:


Is what am describing referred to as communication?

Where both banks can become 48v 205Ah like the scenario I pointed

TechGeek777:


I know LiFePO4 can be paralleled but I wanted to know if there's provision(PORT) for his battery pack to be paralleled like using RJ Connector to parallel both batteries.

@isangjohnson
@valto

What does RJ port have to do with Parallel, Does Solar s or Batteries need RJ before they give you more AH or A when you parallel them?

When you Parallel a Batteries or Solar , you simply connect the + together and - Terminals together to give you combined AH or A.
If you do that for a 100AH and 105AH it becomes 205AH, if you do that on Solar s of 8A and 10A it becomes 18A.

RickyM:

I am trying to believe so…I am in talk with him for 24v 280Ah

He dares not f....k. up!!
The cells I got from him are well balanced too, no funny behaviour so far! The people I got it for used it to 2% at a time, but charged it up to 100% with 0.002 deviation at the end.

Uniquewise:


Really?

Solar s are 300w * 8

Kindly Google search the symbol for AC and DC, compare it the the symbol after your 400v ~ written on that breaker.

The point is, to get me wrong, flooded lead acid batteries should NEVER come to the picture in the first instance!! Cos , it a bettery chemistry been faced out. No body on other side of this world still use flooded batteries. Its was an aberration to start using it here as a new born tech. Immediately they stopped using it out there, they started dumping it here. Flooded batteries were installed out side the living environment of any animal, not to talk of human being!!

Our people started installing it in a human being living rooms! What does that make us?

dollarnaira:

Not as LifePO4 but far better than tubular.
My used lithium ion is going to 2yrs.

Have you ever wonder why phone batteries are lithium? Depending on usage, most phone batteries do 3 to 5 years.

Modern ups and some generators now come with lithium. E get why

I understand boss, i have been using mine close to 4 months, so far so good. Let me see how far it will get me

When lifepo4 started here on this forum, I spoke for it but when I needed to replace my bank then, funds was not available, so I thought and wished. I went for lead acid, quanta (I can never use any brand of flooded, be it Trojan or so). I used my quanta well, I have a meter to check my ah in and out. I hardly go below 65%[I use around 30-35% of the capacity). 4 years is almost here of using it, the capacity has dropped to 30%.

If you must use lead acid, go the route of 2v.

With regards to George D, it is pertinent to note that big banks of lead acid battery in series is a different ball game to big banks of lead acid battery in a series-parallel connection.

Also the inverter with this combo too plays a big role.

That said, I would not personally recommend big banks of lead acid battery where the energy needs is high.

But as they said each should know what works best for them, but in my experience the need to use LA battery (especially for a 12v LA battery) where the energy is high is not something I would recommend, especially for 48v system and below.

Waste of money.
Better on 100ah lithium than 220ah x2 sef

What of original lead acid fullriver

Valto:
ofcourse , i use 2packs personally. 48v 280ah and 48v 300ah, that makes them 48v 580ah

Omo! Nepa go dey beef you ooo

nicodemusic:


Thanks so much for your detailed analysis.. Bottom line is ; should get 2 more s? .. Would 2 more s of 400w or 300w in this case (making 6pcs connected in 2s3p) generate up to 4.8kw or more required to match the battery bank?

Also I noticed my batteries sometimes shows 26v (supposedly charged state) but it would not take a long time before it gets to about 23.5, the inverter alarm kicks off and then shuts down.. Does it mean it's just showing 26v but not charged and therefore not strong enough? My load is always below 10% so I guess the load is below 500watts (since inverter capacity is 5kva)..

I just want to be sure if it's more s I need or if the battery is misbehaving.. Thanks

Bro why are you using 5kva on 2 batteries, you wan kill your batteries be that, and which appliances are you using?

Like every other notable person here has said, many factors determines the type of batteries to gt either old folk or newbie, the cost is the main issues for a lot of folks.

Some installers always present their customers with the lowest possible solutions that wont last.

Many times Hybrid inverters have been bad mouthed here saying this and that abt it, someone even came to this thread with the same idea cos he read it from past posts that Hybrid inverters are bad.

Lets stop all this bad mouthing and condemnation of products, this thread was created for a purpose, its has swerved far from it.

We can air out our opinions in a well respectable manner, not everyone has financial strength to buy lithium battery, while some are making it seem as if using lead-acid or tubular batteries is a big curse.

If you are a lithium share ur journey talk good things abt it make people want to adopt it bt dont condemn where u are coming from, cos you are in a better place nw which is still nt the last busstop, technology evolves everyday.


Lastly i notice we dont talk more abt maintenance here all the time, if you have lead acid and tubular that has been working for you 3+ yrs , share you journey with others, what preventive methods did you adopt to get to this stage and what other equipments did you buy to make it more effective and long lasting for you, e.g battery balancers, how you use them, what kind of equipments do you power with them. Etc

We are all here to learn from one another, nobody knows it all.

Cheers

What sort of inverter with inbuilt mppt charger works well with the battery (5kva and above)

dollarnaira:


Why do guys buy tubular?

I would had rather buy 50ah LifePO4 or scrap lithium ion batteries from laptops than spend a kobo on tubular.

Tubular cost over 250k claiming 220ah ( deceitful) while 50ah cost 140k.

Are you saying a 50ah lithium ba3 will last more on same load more than 220 tubular ba3?

samnaija:


I am using mecury tubular batteries 220ah.

Dats nice, that's the one I am planning on buying. Thanks
