Hello guys!
We try to repair an Inverter RS 48/6000 Smart Solar unit, and I would need help identifying some burnt components:
what we know so far, is that one of the fans made a short circuit and parts of the 48V - 12V buck converter exploded. The unit is not operable, however, the BLE is working, it can communicate with the app (even I was able to make a FW upgrade). So most probably only the 12V supply was damaged…
Here are some photos about the PCB:
We would need information about the exact type of:
T207
T210
And the R219, because in this specific PCB it is missing… it should be there?
Any help is highly appreciated, if someone would have a schematic about this PCB revision it would be great!
Thank you!
best regards,
