Dollarnaira abeg help.

I want to know what configuration and the battery type. With such knowledge I can just add to the battery.

Marykhay:
Maybe the builder na Seun friend I don’t know 🤧

If I had known about the builders in this thread long b4 now, I would have just saved myself from all this nonesense. This system doesn’t even get to 400wh discharge before it shuts down.

bassdow:
the person who built that is a newbie who probably used youTube videos. Sofrey make police no catch you with that things Ooo, dem go think say you dey work with bokoHarfam dem

Marykhay:
Seun stop banning me na

😫

Abeg dollarnaira, Valto, Mrreed and other builders, please what configuration is this? I just opened the system.

This is supposed to be 4S2P for 768Wh system.

bassdow:
you would have to help us identify the head / Positive: the top with pointed tip (koko)

and the bottom that's flat (no pointed tip or koko)

Then we teach you how to identify the configuration.

Also you just can't add extra cells abi battery without knowing the current health of the batteries.

Also, you didn't tell us if it's 12v or 24v or

bassdow:
Just looked at the picture a bit more patiently .

The tops with black color is +ve (positive) while the shiny parts is +ve (Negative)

Now kindly tell us the rating (amps or voltage) of a single battery. That should be on the sticker of the blue body

Marykhay:
Actually, I understand his wiring and so I didn’t include all that part in the picture. But the configuration is not clear to me. I’m thinking he did 6S2P but the bus is obviously a 4S. But I’m not sure, hence why I brought it here

It’s a 12V system.

bassdow:
well as you come exclude certain parts.

Would suggest you just follow the terminals, see how many negatives were joined together, do same with positives. That should answer your question.

The picture not clear as it's just a bundle of entangled

I think I have seen what's confusing you; me sef don loss along the way.

dollarnaira:
Did you build this?
Is it a working pack?

bassdow:
very good question. The wiring dey do mission-Impossible

Marykhay:
No Boss

It’s someone else that built it. I just want to know the configuration he did. The batteries are not strong and so I want to add to it in order to increase its capacity.

Does this help?

Penuelseun:
4s3p, check each parallel cells when the battery is fully charged if they have the same voltage, they may be out of balance thereby causing reduced capacity

Kaczynski:
Your soldering is too poor . are you one of those apprentices at alaba??

dollarnaira:
Dismantle and reconfigure as
3p4s.

Marykhay:
Thanks for this.
Pls I asked about balancing the cells. If I, first of all, connect all of them in parallel for balancing, how long will it take for the 12cells to balance?

oluchibabe:
Morning Guys.
was saying that one can use Recline Nepa Wire to do the Run from Solar Panels, down to Inverter? Is this safe and efficient?)

He said it's not His work. Even me sef no go gree say na my work even if it is. abi you wan spoil market for me ?

If nepa wire can carry live AC current from transformer, then it should be safe..

If you check inside some solar panels cables, the wire is usually same whitish like nepa wire , though more flexible... So they should both be the same.

Buy new one from electrical stores... Full insulated bundle... (Naked one not advisable cos of lighting) Just know that they have different sizes (mm) ...

I use nepa wire for my set up... I think there are 4/5 strings inside and no problem whatsoever

Buy the size accordingly as required

The cost of flex pure copper cables no be here o

Refined Inverter users will say you will burn down your house if it is not strictly dc cables. If you package poo, you go sell am for this country, just make sure your package or "wrap" is very attractive.

bassdow:
abeg leave them let them keep spending money. Even me sef don dey think of selling Solar pure water . The mere fact the word "solar" dey the name means I could sell same for 1,500 naira a piece instead of 3pcs for 100 naira.

After dem don spending more than 100,000 naira to buy wetin the NEPA wire of less than 20,000 naira go settle, dem go come begin dey shop for CHEAPest manPower to handle the setUp.

More interesting is the fact a lot of so called copper cables in market are cheap aluminium cables coated with copper. the greed doesn't even stop there; dem go still reduce the metal inside, and make the insulation thicker to make you think the cable is big.

dollarnaira:
Exactly!
Why you dey hit points this morning bros.

My full copper Belgium Ethernet cable is just there looking for more pv to be added. Shey bi na here all us gather dey.

If you don't have sense don't use Inverter

Unfaized:
The Itel power tank is a low budget solution for intending solar users.

Cost break down ;
Power tank 500w (1kwh) 304k
Jinko 535w bifacial panel 107,500
Installation and materials 130k... Length of pv cable caused the price hike.

Loads.. Normal 32 inches tv
Small Home theater
Lighting points
And a standing refrigerator.
Dc standing fan.

Gets filled by 1pm due to lack of early morning sunlight (Should fill faster in a better location)

A full charge lasts through the night with the above loads mentioned leaving at least 35% charge, although TV and home theater goes off latest 11pm

If you're on a super tight budget and this solution can work for you, then by all means go for it. Highly recommended !
