I really hope someone can point me in the right direction to get my inverter working again. I bought 3 8kw inverters from Foshan Ouyad Electronic 3 months ago and one by one they have all stopped working with various errors and hardware faults (I will post about this soon to warn others of this disgusting company).
The final working inverter gave out 2 days ago with error F90. No mention of this in the manual and Ouyad have been so slow to respond telling me I need to buy a communication board from them to fix this software error. They also sent me some software and a pdf, but following the instructions hasn't helped at all. If what I've been reading is correct it seems they have sold me clones.
The software is Axpert Setting Serial Number Tool V1.00.
It finds my Product ID but clicking apply gives a Setting failed! I am connected via a USB to RS232 adaptor (See attached photo)
The inverter is MPPT MAX-8000 (See attached picture) U1 - 46.04 U2 - 12.13
Not sure where to go from here, anyone fixed this type of error before?
Thanks for taking the time to read and help.
