Good Day, I'm new to the discussion group and messed up the question. I Apologise. Lets try again.
I have 3 Infini 10kw 3phase inverters in parallel. The one inverter suddenly started displaying an error code 90. The particular inverter has been sent to Mustek on 4 occasions costing a pretty penny. Mustek told me to bring the inverter in to replace the main board. The research that I have done seems to be that there is a mismatch of serial nrs.
Is there anybody that can help me to resolve this problem or give me guidance? Your assistance is highly appreciated.
Kind Regards
Dawie
