No big deal. People come in from US everyday and go to their villages to relax for weeks or even months.

Oh, they are Nigerian?

I thought it’s white people coming from yankee and going strainght to one yaba hospital where there may or may not be light

Like that Italian dude, I’m sure mosquitoes must have finished him.

Rough

Imagine from Yankee to Yaba

adrusa:
There are some basic assumptions here that will cause serious problem.
1. I didn't see depth of discharge (DoD) here. For lead-acid battery, you don't have all the capacity available, may be about 50% at best. Some may say 80%, but depending on your load and your cut-out voltage, your inverter will cut off well before you can get to 80% of DoD. So, in calculating your AH need, you must double the result from your calculation. If you need 200AH, get 400AH.
2. I also didn't see "efficiency factors" here. In moving from DC to AC in an inverter, some power will be lost. It is usual to give about 10% of your power to this loss. Also, solar panels also have efficiency factor. This must also be taken into consideration. A 1KW array will not give you 1KW in an hour, it will be less. In addition, the sun is not likely to be full blast for full 5 hours in a day. So, some power will also be lost during cloud passes. Finally, batteries don't convert all available energy to storage during charging. Some of the energy are lost as heat. So, in making this kind of calculations, there is a need to make allowances for these imperfections in electronics.

He doesn't need to double the ah calculation because the OP said he is using Lithium batteries not Lead Acid.

Lithium batteries are a whole different ball game.

GraGra247:
So how do you conclude its inferior without seeing it. I bought that battery brand new.

please note, I didn't come to any conclusion, just a guess.

that guess is based on my experience with buying 3 different sets of batteries from nigeria that never made it up to one year

we now use lithium phosphates at home after having bad experiences with lead acids from nigeria.

so i'm just guessing that a combination of bad/inferior batteries plus a bad charging algorithm (like charging at too high a voltage or too low), plus imbalances may have killed those lead acids.

i can go on an on about lead acid batteries from naija, but, really it all depends on budget and how long you expect them to serve you.

GraGra247:
Please what's the function. My inverter battery always misbehave. Can it help??

Nope! it's for people that have solar panels and use those to charge their batteries.

There are a no of reasons your battery could be misbehaving, from bad/cheap batteries, to a bad charging algorithm.

My money is on inferior batteries though.

How much?

Hi there, it's 20k negotiable.

Lekki, Lagos.

okay this has been in my closet for over a year now

need to get rid of them.

blue one works, black one needs a battery

call 0818-242-4406

and who knows where I can sell inverters that don't work anymore?

get a used solar charge controller for a fraction of the cost

20k, negotiable

call 0818-242-4406

Hey guys, still selling this mppt 48v/24v charge controller

20k

call 0818-242-4406

still available and cheaper than even your basic pwm.

Still available. Use the second one for parts like transformers.

Trippledots:
Mppt or pwm?

It says MPPT, there's really no way I can verify though.

When we had it in service, our panel voltage was about 65V, feeding into a nominal 48V system.

Ewuro2:
Who is this IMPERSONATOR?

lol, huh?

A40:
He does everything at his own pace. I see why Kendrick compared him with the GOAT in a way.

what James Harden couldn't do.
