Note: DC/AC ratios of 1.2-1.4 are typical for utility-scale. Higher ratios reduce inverter cost per watt but increase clipping losses.

Reference

AC Capacity Needed = DC_capacity / DC_AC_ratio Num Inverters = ceil(AC_needed / Inverter_unit_size) Actual DC/AC = DC_capacity / (Num_inv × Inv_size) Clipping increases with DC/AC ratio above 1.2
