Over paneling MPPT, short circuit current too close?
With 2 strings in parallel I''m worried that the short circuit current is too close to the max PV Isc of the MPPT. These components are already purchased. The only thing missing is to decide the panel setup. - Battery: 48V, but for solar panel to solar panel Isc comparisons you don''t do any adjustments. So in this case it doesn''t make
