My 'MUST' solar 3 phase Energy Storage Inverter(12KW, 48VDC) can charge alright but is not transferring power to the output (AC ). It shows an error code of 80 which says CAN fault in the manual i downloaded. I removed and re-fix all the communication cables but the problem persist.
Will happy with any help on how to go round the problem. Thanks.

Thank you very much Peter. I have done all you suggested its seems the problem is software or firmware. i have seen the CD that came with the unit so I will install it and get back on what ever happens.
I appreciate your effort.
