Photovoltaic inverter ratio

The DC-to-AC ratio — also known as Inverter Loading Ratio (ILR) — is defined as the ratio of installed DC capacity to the inverter’s AC power rating. It often makes sense to oversize a solar array, such that the DC-to-AC ratio is greater than 1. A PV to inverter power ratio of 1.15 to 1.25
