What size charge controller for an 800w solar panel? In general, if your battery bank has a nominal voltage of 48 Volts, you would need a 20-30 Amp MPPT charge controller. The Output Current rating of the. . Suppose the solar panel array has 30A (amp) output current. To compensate for solar array performance in cold weather when the panels operate more efficiently, a safety factor of 25% must be added to the 30 A. . Although the maximum PV voltage (42. 3V) is well below the maximum PV voltage of the charge controller (100V), the maximum output amps I can generate (34. Since the Victron MPPT calculator yields the Victron SmartSolar MPPT. . 10A vs 30A solar charge controllers aren't just numbers—they mean different beast sizes for your RV's solar setup. 100Ah / 20A charging current = 5 hours Keep in mind the recommended charge rate of a battery. For a lead-acid this will be 0.
