Reinhard got a reaction from Coulomb in Axpert MKSii problem - output power "weak"It was the problem. I'm not at home. I explained to my wife how to change the setting and now everything works 100%.

Reinhard got a reaction from Coulomb in PV dropping (Axpert 5kVA)Finally I found out what the problem was. One day, after becoming crazy deparate (my wife struggling without electricity and me working 700km away from home), I jumped into the car and drove home. When I got home, I went to the inverter, opened it and say a small white plug, that wasn't plugged in properly, like the one in the picture:
I plugged it in, the solar detected and that was the end of the problem.
The inverter ran perfectly, never switching off and the battery never went flat for 2 months. Then one day I was in the garage and I heard a loud pop and the power was down. Now the battery (Pylontech UB3000) is detecting a short and the red (ALM) light goes on and refuses to start. There is a short over the 2 poles where it connects to the inverter. The inverter is dead. What could have happened and what could the damage be?
I have ruled out problems with the PV, as I am borrowing and inverter and it shows no problems being connected in place of the broken one.
The wind was not blowing, there was no thunder and its a completely off grid system, so there was definitely no power surge.
The inverter had a 1 year warrantee, that expired a month ago.
