Why are solar inverters sized lower than kilowatt peak?
Inverters are usually sized lower than the kilowatt peak (kWp) of the solar array because solar panels rarely achieve peak power. The solar array-to-inverter ratio is calculated by dividing the direct current (DC) capacity of the solar array by the inverter's maximum alternating current (AC) output.
