How does sizing a solar inverter work?

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.
