Its weird the power of the batteries increases, I don't understand anything, I've never seen it.

The "panels" and "battery charge" functions seem to work, it is the "conversion to 230V" function that is messing around.
You are charging your batteries at 30A, or 1,37kW. There must be sun!

Yes there is sun
I found this little fuse that I had with the inverter,
Shouldn't I change it?

You show us a new fuse, so that we answer shows you which one is installed. You can also see with your eyes if it is cut or not ...

Have you measured the voltages of your batteries one by one, to see a difference in voltage between the batteries or not?

You have to disassemble to access the fuse, I remember when I had made the connections, these the same apartment as it was marked 150 on the black part and do not think we can see it if it is cut in relation to this part black.
I'm taking apart this afternoon and telling you.
No I did not measure the voltage of the batteries, because I do not know if I have to dismantle them all one by one or test as they are there (in 48v). And tension? (the vlt which sort?)

Here is the fuse change but nothing helps, always the same and also a photo of the open inverter.

I have to make myself a reason I had to burn it by turning on this drilling pump, I shouldn't have, but now these fact ...

I will try to plug in my little 1400w hybrid inverter, it will always help me out, at least for tv, light and box its will always be better to turn on the group continuously.

But will it not do too much but 7 panels of 300wt plugged into it? How much do I have to unplug?
Of course I will switch my battery pack to 24v instead of 48v.

Here I just modified the installation
I connected only 2 panels of 300wt in series on the small hybrid inverter of 1400 w which is connected to 2 batteries 150amp connected in 24v.
Its working but with this installation I can only use the tv, light and box. Its little you would say to me, but zes always better than nothing and its saves me from leaving the generator set on all day ..

Until I get a bigger inverter. But now I'm afraid of being wrong again ..

Better a hybrid inverter or a normal inverter? who can advise me
Thank you

For the batteries there is not the same voltage, there are only 3 which are identical 13,4v and the other 12,2v
I will have to test the 2 others of the same brand and the same amperage that I have to see,
(could not test them today because I put them at a friend's house to be recharged)
