    Inverter firmware downgrade

    Hi!

    My GW5048-EM inverter started displaying a BMS warning (communication Fail) after it's firmware was changed (by goodwe) from version 3111112 back to 3111108.

    Is it normal for an inverter's firmware to be downgraded in this manner?

    Before this downgrade the inverter was working perfectly.

    Thanks for your question. The communication fail happens because of the downgrade. Cause Ver3111108 might be not compatible with your battery. I think you need to upgrade your version.

    Hi, I had Goodwe also playing around with Firmware up- downgrades. At the end Version 3111113 works perfectly well with 5048EM and LG RESU 6.5.
