Good day everyone, I trust that you are doing well. I am posting this on behalf of a friend. He has accidentally powered on his generator to his workshop, while his 3kva inverter was running output to the shop. That caused a loud bang inside the inverter, which happened to be two of the four transistors that blew. He has since replaced the two transistors with new (similar) transistors. Now he keeps getting the error 05, which means circuit overload/overheat. Does this mean the system pics up the new transistors as not being original/exact match? And is there any way of bypassing the error 05? There is a com port whereby one could connect a laptop and possibly bypass the error 05, if that would even be a solution. Any help or recommendations wil be appreciated, thank you.
