Hello sir, see the attached of the voltage after switched off of the generator(12hours)..before loading

ojeysky:
What was the voltage after the 12hrs but before you switched off charging source? If it was 50v as indicated on the picture then the batteries did not charge at all.

Thank you for your feedback.

You need minimum of 6.5kva to power a 5.0kva inverter efficiently.

Thank you for your response. It's actually 2 transformer according to my supplier. Here is my observation. I charged(displayed) charging for 12 hours with 3.5kva maxi generator for 5kva inverter 48v, 200ah, 4 tubular batteries, and after loading it, it only lasted for less than 2hours. Meanwhile, when am using only solar panels it last for about 5hours for same loads. See the attached images(note from the images,I was using ups inverter before, then I changed it to kartel. Still same batteries) just to clarify that. Thanks

If its a hybrid, most likely.
If its a transformer based and in good health, most likely as well. However if your inverter has adjustable charging current setting, you can lower it til the gen can carry it.

For example, my old 4ka 48v mustpower transformer inverter, my 8kva gen charges it ok at max batt charginf current of 31amps, but when i use my 2.8kva gen, i have to reduce the charging current to 7amps ,if not the gen will cough and die

Hello house, I have a question. Can 3.5kva generator charge 5.0kva inverter(48v,200ah, 4 tubular batteries)? Or what's average generator I can use? Thank you all in advance

@kagari, I would be making a first time international trip to Cameroon next week. Any cheap flight please? I would be going through Lagos, any tips please for a first time person? Thanks
