Hello,
I have a Victron system (3xMultiPlus-II 48/3000 / 6xPylontech US3000C / Raspberry GX). I also have an old SMA system (1xSunnyIsland SI 6.0H / 1xlead battery 48V - 6 PzS 930). I would like to replace the SMA-Sunnyisland with a Victron MultiPlus-II 48/5000/70-50. Can I get this controlled with one GX (2 different batteries systems) or do I need another GX?
