I am using the GROWATT SPF 5000 ES OFF GRID, 5KW, 48V, 100A connected to a 230V AC source to charge 48V 20A lithium-ion battery pack cells. I am presently charging one at a time for fear of damaging the Growatt if I add more. Is there a charge management circuit I can use to safely charge 4 of them loaded to a Growatt at the same time?
