Hi all,
I am having more than one issue with this heavy box...so guess, the newer firmware should sort it out, or at least I tried it!
Basically, the usual problem with USE vs US2 as I use a non-communicating battery stack, and then the inverter sometimes gets confused over the switching to the utility source once the battery is depleted. Plus some more, of course, can't even recall what else I experienced with it!
So my inverter firmware version is 508.02/037.01.
If anyone knows where I can get new firmware, please don't hesitate!
For everyone asking why I haven't contacted the Growatt...I did...two years repeatably and not one single answer, regardless of which email I struck!
