Can a solar inverter be bigger than the DC rating?

The size of your solar inverter can be larger or smaller than the DC rating of your solar array, to a certain extent. The array-to-inverter ratio of a solar panel system is the DC rating of your solar array divided by the maximum AC output of your inverter. For example, if your array is 6 kW with a 6000 W inverter, the array-to-inverter ratio is 1.

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.
