Can i use a UPS as dumb charger?

by now, you should have used a voltmeter to check the batt voltage, and inform us.
dumb charger is available on jumia /konga.....
if you are savvy, there is a way you could adjust your cc settings, and try to use it as a dumb charger, but from your questions, i highly doubt, you have the skills to try the above suggestions.

if the battery is so dead, that it has short circuited, so trying to force charge it will damage whatever equipment you are trying to use to charge it....this goes for ur ups question

First, I think it is better you find out the voltage of the battery. There are very cheap meters out there that can do that. To answer your question, the UPS can not function as the dumb charger. When you find out the voltage, the best option is to try to charge the battery in parallel with another healthy battery. This is just a 50-50 affair as your batteries may be irredeemable at this stage. But you can't be sure unless you've tried all the options available.

Time to try to charge it parallel with a working system. Find a friend with a working system. Turn off the friend's inverter and connect your battery in parallel with theirs. You may require the services of a sort of expert to pull this off. After some minutes, say 30 minutes of charging. Disconnect your battery and measure it. If the voltage rises to about 8v or so and stays there, you may just have a working system. But if it didn't, you may just have to get a new battery. I have once used this system to revive a battery reading 0.5v and 1v etc. But sometimes the batteries will refuse to retain any voltage in them after this stunt. By then, you just don't have any choice but to sell it as scrap and get a new one. It's a tough pill to swallow, but then there is some lesson to be taken off that experience.

Check the diagram attached; a very rough hastily sketched diagram grin but at least it may give you an idea of the connection in parallel. Please mind the polarity of the batteries while doing this, hence the need of an expert or someone who knows about battery connection. This is just to give you an idea. Cheers.

Guys I'm looking for a fairly used 500w-1kW 12v Hybrid inverter, hopefully from anyone here that's looking to upgrade to a 24v/48v system.

Kindly quote me if available. Direct owner please.

Wow this is definitely a critical battery volt & definitely 90% irredeemable ! Was the said battery left uncharged for years ? What drained your batteries to this battery volt level ! You also need to check the "LBCO" of your power inverter if you end up getting another set of batteries alas .. Cheer's

Why not go for the newer model; the GK or MK series

Hello guys, i have been away from my solar inverter system for a while, i got back and i was told the system stopped working about 6 months ago, the sad part is that they ran the battery flat too. I found out the problem is from the panel wire.
The problem now is i have been charging the battery with Nepa via the inverter for 5 days now but its not coming up. I fixed the panel connections too and still battery is not charging, there is no display on the charger controller too.

Please guys are the batteries gone?

Get an external charger and fire cheesy. It would come back to life if you are lucky, samething happened to my client that traveled out of town. I was able to recover it.

You can check their documentation at their website below. A few differences:
GK: Batteryless, and high Voc, 3KVA has 80amps charge controller, support 4000W panel
MK: Parallel support, zero switching delay, low VOC, 3kva has 60amps charge controller, support 1500w panel

Hello Topmost11,

First of all, there's a general calculation used to determine the size of PV array for a particular system, and it has to do with using the average hours of sun in the day and other many scenario.

however, I'll show you how I personally do mine looo�.

secondly, I'll go the 24V way.....
so, for a 400Ah battery bank, you need a minimum charging current of 40A (10% of the battery bank capacity). However, some battery have exception to this: Quanta Amaron can take up to 25% of its capacity!

so at 40A charging current, you need 960W PV Array (i.e. 24V x 40A)

Nonetheless, there are other considerations like day loads, panel inefficiency, and cloudy moments....

if you decide to add 10A to take care of the day loads, you'll have 50A.

That'll be 1.2KW PV Array (i.e. 50A x 24V).

However, you should round it up to 1.5KW PV Array, to take care of inefficiency.

Note that the above is strictly my personal approach....

Cheers

what about i have solar 8 modules rating (250w, 30v, 9v) and is connected 4s2p to a charge controller of 150v/30A(pv rating) to a 400ah battery. Will this charge adequately?.

Note that the panel connection will give 120v/19amps(Mppt controller), difiling the c/10 rule but multiply amperage will still gives same watt that will let the connection be made in low wire ratings...

Does the GK series mix grid and solar power together? the MK series does this flawlessly.
Simply put, if grid line (PHCN) is present and the solar panels are active during the day, the MK series inverter will draw power from both sources thereby reducing your PHCN bills
For most other inverters, and CC, they cut-off the PV to 0W production when the batteries are fully charged and grid line is present.
Imagine your batteries fully charged at 11am in the morning with grid line present and the sun is still hitting hard , all that goes to waste.
