good afternoon house,is this lithium battery good product for my 12v inverter please

osayuwamwen:
Just close eye buy am, am telling you from experience you won't regret it, but if u buy that choice u go regret am, e go b the issue of penny wise pound foolish

bassdow:
wetin carry you come this thread Oga ?

Gshems:
make people no cut cost on wires. Wires and breakers are major cause of these fires. An installer once used a 1.5mm wire for my inverter connection. Once day I went there as a curious person and I saw that the wires are burning already. The insulation was already burnt. I upgraded everything to 2.5mm.

osayuwamwen:
It doesn't show on the inverter, even when I leave the inverter screen on the interface were the pump load in kilowatt will show before switching on the pump the only tin that shows is the Amt the pump is pulling currently which is 1.9kw sometimes it fluctuate BTW 1.9kw and 1.8kw

osayuwamwen:
Am only seeing constant 1.9kw on the inverter

osayuwamwen:
I just try it again now with no pv input and it still carry the pump and it pulling 1.9kw too, I think the issue was with the pump at first, reason it was pulling 4.1kw

I moved into an area that had light problems in Lagos Called Ijegun

This started my journey into inverter and then solar upgrades

As I moved in here in 2023 and saw the state of the phcn here, I needed something that I and my family could use at night, as against running generators through out the night.

having bought 2 batteries (1 55am lithium ion in 2023 and a 100am Lithium ion in 2024)

The 55am battery came with a 1000watt modified sine wave inverter,

It kept 2 DC rechargable fans running for 4 hours when fully charged, with the inverter making noise so loud.

When the 105am battery came with a 2000watt modified sine wave inverters and each came with lithium ion battery charger.

I felt that would at least carry the TV as extra, still increase the fan use by about 2 extra hours.


Then in February 2025 our transform which only provided low light blew(how that happened I do not know), phcn came to inspect then later came to carry it.

It's March 2026, still no hope for it yet, and through out the time I ran a 6kva generator to charge my batteries every evening, that became too expensive, so i got a tiger Gen and modified it to be able to charge one battery at a time for 3 hours a day(if you have ever had to run generators during the night 9pm-12pm everyday for 10months, you will understand the expense and maintainance cost, which far out weighed the cost of getting a fully solar option)

Which is what I decided to do in December, took an upfront reached out

Got someone who decided it's best to save cost by using my batteries and just getting an new sine wave inverter (euronet 1.25kv) and panel(went with 6 200wat tiny panels)

Since installation, I have literally abandoned my my street discussions about the transform, as if it does come, it's ok, if it comes it's ok.

My wife gets to finally use the fridge for 12 hours a day, with watch the TV . For me the big one was I could finally get to use the washing machine during the day(although I technically have to wait for sun to be at its peak and switch off every other thing in the house).

This been 3 months, and I have more than 22 hours of light (switch off the inverter for 3 hours a day during the evening)

Now I am looking to upgrade the inverter and add another battery.

Any recommendations would be appreciated

My setup


Are your batteries lithium?

bassdow:
what if the Customer is to be blamed ?

Except they are widely known to be unreliable, this shouldn't be an advice abeg. No spoil market for people unnecessarily.

Topper33:
Thank you Sir


I think the Sako setup is looking good. Although the total cost is slight above my budget

Asides, these, do i need any other thing?

osayuwamwen:
Is it something like this? And which of the kw am I buy? 1.5kw

osayuwamwen:
Pls my 4200watt luxsun inverter 24v could not power my 1.5hpower submersible pump, but it power my electric cooker and hair fryer, when I on my pump the inverter shows the submersible pump is pulling 4kw and shows 100% load. 1.5hpower submersible pump is less than 1500watt I think

bassdow:
Kindly tell the person who setUp your system and He or She knows what to do. That's if your isn't already.

bassdow:
what's model of this inverter. Reason I asked is that error 8 mostly mans the Voltage from DC source is very high.
8pcs of 620w solar panels, hopefully were all not connected in series BUT we need know the model of this haisic inverter or you share picture of the sticker on the inverter's body especially the MAX PV input.

Most times, people only do simple maths on solar panels not considering other variables.

Also rushing to change a blown fuse or breaker, without trying to figure out the primary cause is wrong.

We need first be sure issue isn't from solar panels, before considering other variables. Also help confirm if you completely off NEPA / Gen.

I am also sure that inverter isn't grounded.

Penuelseun:
buy from techland, they sell original Jinko panels

osayuwamwen:
It doesn't take long if u made payment once, it is only when you are doing pay small small, and you spread your Payment to like 12months so u will have to wait for like 6months which is half of your payment time frame before your item will be delivered to you then you can now pay the remaining half within the remaining times, I bought 4 of my jinko 535watt bificial panel at fouani when I went back a month later to buy the remaining 3 they were already at of stock so I later bought the remaining 3 from cdcare, with 2 month installment plan as am talking to you am still owing then money for 1 panel but all the panels are here with me am installing them 2moro, cdcare is safe them go parkage your panel well with wood to avoid dent or scratch )

cyif2003:
Okkk

bassdow:
you obviously don't know meaning of /

bassdow:
first buy 24v battery either used (Tubular / SLA / Lithium) or new Lithium.

Come back tell us how much remain. So we give you the rest. for your budget, you would have to use more of used items especially (hybrid) inverter

Ofejiro20:
Thank you but would you prefer to have so much panels of 350w, 450w littering on top of your roof or just a single panel like 710w which will cover for two of 350w boss? Just a food of thought though.

tziz:
Bro, tell me about this battery pls, I posted it here some days ago and asked for user reviews but got no response. How good is it? Grade of cells? BMS? Does it have Bluetooth remote monitoring?

tziz:
Abg best 12v 200Ah LiFePO4 battery to buy with a budget of 370k??

Marykhay:
Charging voltage is set at 14.6V. And it beeps everyday on the inverter whenever it’s full.
However, it just doesn’t last up to 700Wh.

As for the balancer, can you kindly post a picture of your recommendation?

Marykhay:
Chief thank you. Though I just confirmed earlier this morning that the imbalance in the system is not significant:

Battery 0 -> Battery 1 = 3.18V

Battery 1 -> Battery 2 = 3.18V

Battery 2 -> Battery 3= 3.18V

Battery 3 -> Battery 4 = 3.2V


So the problem is why is a 768Wh system not up to 400Wh from my capacity test? Are they fake cells? Or is there some other problem that I don’t know?

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?

fuckboys:
why una dey mumu like this? Somebody stated for charging of phones and you dey recommend 24v?

The person even stated his budget in this economy and you Dey tell am to up him budget to a million plus. Will you complete the money for him?


My 12v system wey I dey use iron clothes and pump water.

bassdow:
Those spending over 1.5 million naira buying things brand new, ought not be buying like they're buying used item hence limited. A lot of times sef, we end up overSizng our battery bank. Once again, 48v 200Ah is better than 24v 400Ah. Feel free to argue but I'm off to bed. Should be back by say 3am or so in case anyOne is interested in increasing the number of pages of this thread.

Sometimes person need deStress but at this time, my eye lids are falling in love with each other so let me let nature play it's role

bassdow:
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.

ishayaauta:
Omo na wow oooo

Okay if I need the 5kw battery
How many KVA inverter do I need and what type of charge controller will I need if I should up my budget to 1.5M


Thank you so much for your response

ishayaauta:
Hi everyone I need to setup a low budget solar power station that can power 2Laptops 2phones 1router 90w fan and 1TV for 24hrs. What budget should I work with and any advice on what and what to get will go a long way my budget is 200k to 800k max

Abeg na newbie I be for this thing

sofdoc1:
Thanks for the reply. But I don't want to get a local battery. Do you know of any imported 10kwh battery priced at 1.7 mil
