I'm not sure it's an Axpert Clone, but then. Attached is the Name plate.

I'm looking for a third party monitoring app like Home Assistant to integrate TBB inverter. I have not seen any mention of TBB Inverter in any of such. Not even Solar Assistant or ICC. Will be grateful for any information. Thanks

I'm sorry Easun does not make spare part easy to get. I had to repair mine. Thanks to advice from Coulomb. How badly burnt is your board? Do you have a little experience solering electronic componets? And can you post the photo of the board?

Confirmed it goes to the two pin PCB connector. And works with the Power on switch. Now we are back online, tough blind. Will either buy a new Comm board or repair the faulty one or both. Thanks Coulomb, I owe you some beer.

Hi, grateful for your kind support. I'm feeling happy now. Powered on the Battery and the inverter seem to come online but no output. Was able to hear one relay click. And the fans blowing. On your suggestion to use the RJ45 coupler. My Comms PCB is only connected to the inverter system via two PCB connectors CN1 and CN2 Do you by any chance have a circuit drawing of the said board? Maybe I can pull out the two cables for switching on the inverter from bypass. While wait for the Diodes to come from China (45 day avg) Thank you once again.

I have this Axpert 5KW from Easun SMK 5KW. Over the weekend rain splashed on the remote Panel and the Comm Board (Part #: 16-501026-00G) went up in smoke. Was able to quickly short the inverter down. After investigating, two diodes (BX320) were burnt. My question is it safe to power the inverter without the Comms board just to test if something else has gone bad. Ordering for the Diodes will take more than a month. Has anybody experienced the Comms Board blowing up? Did you replace the remote Panel too? Grateful.
