My Quattro is reading the incoming power incorrectly

Quattro Reading incoming power wrong
If that is a generator, it is not running well or something is happening on one phase there.
(Weird frequency if it is grid.)
It is likely the power is being rejected as it falls out of parameters.
Did you use a good DMM to verify the incoming voltage and verify the correctness?
The system has reset itself so everything up again. The issue is still that the inverter is reading the power incorrectly. I have tested all 3 phases coming from the generator to the db board and all are 231V. I have also fastened all the cables again and nothing is loose, the generator starts automatically but the one phase still reads between 255 and 276V, it sometimes dips below 250V and the batteries start charging.
A new inverter is on its way and I will seel if that works :-(
