PV modules do not consistently perform at their nominal output rating. The module output power is affected by the weather, the sun’s position. .
SolarEdge allows DC/AC oversizing depending on the inverter model. .
The main reason for oversizing an inverter is to drive it to its full capacity more often. Oversizing the inverter is not a requirement. An experienced PV designer might choose to. A DC-to-AC ratio of 1.25:1 ensures that your inverters are being used to their full potential. To calculate the DC-to-AC ratio you must first calculate their individual capacities. For example, to determine your DC size, you multiply the number of solar panels by their max output in watts.
