SRNE lists maximum PV input of 22.4kW for the 14kW model, 25.6kW for 16kW and 28.8kW for 18kW, equivalent to 1.6× the corresponding rated AC power. That extra DC capacity helps the three phase solar inverter collect more energy during weaker irradiance and supply both loads and battery charging. Continuous AC output is still limited by the inverter rating, and each MPPT must stay within its own voltage and current limits. PV oversizing should therefore be designed, not simply maximized.
