Hello, greetings and many thanks for the efforts. I have easun swm 11kw twin with detachable display, I have flashed 978.10 from the above post over original 78.10 firmware, but I still have charging limited to 100A. Any ideas? Thanks, regards. EDIT: I think that could be because my grid voltage is extremely high (253-257v) and if I read correctly >250v is a derating condition while my inverter temperature is around 47-50*C. If I turn off the grid, it goes to 115-120A for a short while, and then capped to 100A again. Is 0v grid also a derating event? Regards
