Hi community, I had a AC200MAX charging with PV350 panel + B230 battery these last couple years (apart from the battery % full indicator bug, everything was good).
This month, got a 2nd PV350 (new model) connected in series to same battery set up and works well. However I’ve added the new B300K battery pack too, but now the B230 isnt charging, just stays on ‘Stand by’ despite the solar panels sending Watts. Both batteries are connected separately to the AC200Max via the 2 battery inputs. I realized it might be the reason, but before plugging the batteries in series, wanted to check for help that I won’t do damage or what order (if it matters) should they be connected in (ie AC200>B230>B300K or otherwise)?
Many thanks
