    Hi Coulomb,

    I was told maybe you know what to do with my inverter.

    I have a three phase installation with Growatt SPF5000es inverters. After 2 weeks, I had no longer communication BMS with the pylontech 2000C batteries and could not find the problem.

    I tried to update the firmwares under win7 (I was told  that it doesn't help for com issues but seemed at the time reasonable). Two updates went well. However, one inverter didn't accept the 040.06 FW, but did accept the 041.06. I did a hard reset, with no success. All leds of cards are still operating but I get "send start" for hours.

    Now this inverter no longer detects solar and is no longer detected by the other inverters (error 17) but it still starts and seems operational. I also have full access to the menus. 🤔

    Can it be related to the com card or ... ?

    Thank you for any suggestion.

      Alas, I don't know much about 3-phase inverters, and not much about Growatts. But they do seem to be based on Axpert designs, so there is some hope of me making sense.

      All I can say is, maybe, just maybe they operate like the Axperts, and you can retry the firmware send. It sounds like you already did that, but maybe you need to turn on AC-in power at just the right time, like with Axperts.

      See here for all I know about restarting Axpert main firmware updates.

      Thank you Coulomb for your answer and help. I will give it a try... or purchase a new board if it fails.
