Hello, I'd be also interested in the firmware updates, I'll probably need it I have a system set up at home that worked from day one no problems (Growatt inverter 5000ES with 3 plyontech batteries 3000c each ) Now I am trying to set up my uncle's the exact same way as ours but it doesn't supply energy to the house( bear in mind I bought everything the same as ours). I tried different settings on the inverter putting Li on 5 and when directed 36 I put 52 as ours. It doesn't show any error sign everything seems to be fine except that no energy is supplied to the house. And when I check the menu on 2 the charging Amper shows 0, and it doesn't allow it to change. Then I tried as per other examples on YouTube to set Li on 5 and at 36 to put 01. Now with that I get error 4 and 20. I'll try these settings you provided here. And if it doesn't work the next step would be to do the update. Thank you and hope it will work. I'll try first to adjust the cable and settings and if it's not working will do the next step.
