I have Multiplus 48/5000-70/100 3-phase system that I would like to upgrade with 3 more Multiplus 48/5000-35/50. The system is configured as an island so no need for high transfer etc ... Charging current is not an issue since I also have MPPT's installed.
So my question is if this is possible if the firmware versions is all the same?
Thks,
Jean-Paul
