The size of your system and modules is measured in Direct Current (DC) power, which is not usable in the home. The string inverter or micro-inverter converts this to Alternating Current (AC) power, which can be used in the home. The size of the inverter(s) represents the AC system size. Oversizing the system for the inverter has several benefits, including accounting for DC to AC power losses, enhancing the system’s lifetime performance, increasing annual output, and ensuring optimal performance during low sunlight periods.
