Hi, i am new here, my name is David and write this from Spain.
i need help with my design of a ESS system.
I have 4100w solar panels, sma inverter, two quattro 48/5000, one new, the other with older firmware, that no support ESS systen and parallel running with the new quattro, two banks of bateries ni-cad, 48v 200Ah.
