Terminals are clean but it is the Board behind that looks scary



I opened it up and saw that the battery Juice had reached the Board and left some blue residue on it.
It is likely alkaline in nature and may have corroded some things.

Attached are HEAVILY-blown-up pictures.
Can it still be repaired and if so HOW?
Can anyone walk me through the process of what to do

Thanks

first of all, disconnect the power source (battery), then use soft toothBrush and petrol to wash (clean) that circuit board. Just dip the toothBrush inside a container of petrol and use to clean that board; try not to scrap anything, just clean. That should be first attempt BUT if you wanna spend money, I fit help you BUT really, it's something you could do.

After the cleaning, we follow next step.

Alternatively, take it to an electronics repairer (popularly refered to as electrician / radioNic), and show them. They should be able to help you.

Sun dry it ,you might be lucky.I remember my prepaid meter CUI had similar issue.The battery overstayed and released chemicals into it and it stopped working. I loosened the board,sun-dried both sides of the panel and it and it is still working till now.

so you waited Till I was about submitting my response before you sent yours.

Either way, that him/her own stage don pass wetin dem dey sunDry

Good afternoon sir….my Budget is around 1.5 to 2m and I want the set up in a 3 bedroom apartment in Ibadan….my appliance are one 65inches Hisense smart TV and a 50 inches normal Hisense TV not going to use the 2 at once tho, a PS4 game, one 201L Hisense Freezer LG washing machine, thermocool gen pal 1hp inverter AC and blender 2 fans that’s all I want to use it for

Someone is offering me felicity 5KVA hybrid inverter for 550k and 5kwh felicity battery for 1m and 8 pieces of 350w panels for 70k each for 560k not sure the name of the panels then 100k for installation I don’t know if that’s a good deal and if the products are reliable….please advise sir’s

at the price of 70,000 naira per 350w solar panel, na you dey loose Ooo.
Go for atLeast 500w or 450w Solar panels new or used.

you didn't indicate if what you were being offered is NEW or USEd.

Also for your load type, 5KVA is just a baseline. Should work doesn't mean the system would be comfortable. To have some headRoom, go for 6.5KVA, or 7KVA and above.

Also would suggest you go for 48v even if it means going for a lower battery capacity e.g instead of 24v 8kwh, go for 48v 4kwh BUT if you have more funds, try go for something higher than 4kwh at 48v but at all at all, 48v 4kwh is better than 24v 8kwh.

First of all, kindly inform us if what you being offered is NEW or USED; don't wanna assume

First, get petrol and clean with brush.
The acid had shut some components.
Try this first and test.

Solar energy can be a strong complement to Free Trade Agreements (FTAs) because it supports economic growth while reducing long-term energy costs and environmental impact. FTAs are designed to encourage cross-border trade, investment, and technology transfer—and renewable energy fits naturally into that framework.

By lowering trade barriers on solar panels, inverters, and related components, FTAs help countries access affordable clean-energy technology. This accelerates solar adoption, strengthens energy security, and reduces dependence on imported fossil fuels. In turn, businesses benefit from more stable electricity costs, which improves competitiveness in international markets.

Solar energy also creates local jobs in installation, maintenance, and engineering, ensuring that the economic benefits of trade extend beyond imports and exports. Companies like Wolf River Electric show how regional solar developers can translate global trade advantages into local economic value by deploying proven technologies efficiently and responsibly.

As governments continue to negotiate and expand FTAs, integrating renewable energy priorities—such as solar—can help align trade policy with climate goals. Resources and insights from providers like Wolf River Electric highlight how solar solutions can support both sustainable development and the broader objectives of free trade.

Haisic 24v hybrid inverter 4.2kva 350k
Haisic 24v 8kwh Lithium Battery 850k
Alternatively Mr reed's 24v 8kwh lithium 870k
Jinko solar panels 535w bifacial 4 pieces 430k
Materials and installation 200k ish

And you're all set.

If you can expand your budget and you're looking at taking on bigger appliances later in the future then just go for 48v system.

I use God beg you. No matter how sweet this 350watt panel deal looks abeg avoid it. The battery and inverter you can still consider butt do not buy those 350watt panels

As how? And since when?

I just collected My first humsienk 314ah 12v lifep04 battery I ordered from jumia today, am ordering another 314ah today, am upgrading from a 12v system with 220ah tabular battery to 24v of two 12v 314ah lifep04 battery and sms 5kva hybrid inverter ☺️

But wondering why you didn't buy from guys here?
491k plenty oo.

60% DOD(depth of discharge) means you cannot pull more than 60% of the battery juice. However, all lifepo4 can do 80 to 90% DOD.

YOU DON TEY FOR THIS THREAD and to me it is not a good buy. It is your money, no vex.

491k is a good buy for a 12v 314ah capacity chief. Let's be sincere.

The best budget in the market now is haisic and the transparent cola solar battery which are 280ah going for 450k

bro how's a 4kwh battery better than 8kwh battery? Hope you know capacity is different from voltage?

Bro
His money, his choice, not mine.
60% DoD, dumb 100a bms, 491k is red flag for me.
True capacity of 300ah (314ah) is not yet confirmed o. That 100a dumb bms is the best red flag.

But raw 314ah cell here are 333ah true capacity at 360k or less with dumb bms of less than 60k. No be argument oo. Na im choice.

To all those asking questions around the lines of "How is 48v 4kwh better than 24v 8kwh"

You guys need understand no be everyTime I dey get time + strength + willingNess to type plenty.

I suggested this person go for higher voltage even if it means getting half the amperage. I could easily tell you why BUT the tone tells una don conclude already; just want to hear from me for hearing sake.

Abeg make una manage google or chatGiBiTi afterAll una talk say na wetin I dey use

From Jumia

It means that the Humsienk LiFePO4 battery is designed to be charged and discharged 15,000 times or more, provided that you only use 60% of its total capacity before recharging it. , the question should be how many years will it take me to get to 15,000 cycle?

You sure say no be marketing you come do?

Cause if you think you know so much, why come here to ask for people's opinion on the battery

this go still confuse a lot of us including experts amongst us. Just give them this

48v 4kwh is better than 24v 8kwh

Ah = (kWh * 1000) \ V

using above formular 48v 4kwh gives 83.3Ah WHILE for 24v 8kwh it's 333Ah. Also the 48V comes with lots of better advantages than 24v. The only one better than 48V is something higher than 48V e.g 96v or even 50v if you see am.

All na marketing, advertising a product as 24v 8kwh appears much more appealing than 24v 333Ah and when the likes of us talk, those wey don position demSelves to benefit go begin itch for brain.

We don talk am plenty times, the higher the voltage, the more efficinet the conversion is. anyOne who's played with the likes of LM7805, MT3608, etc can't easily miss not knowing the above directly or indirectly.
