What is a good DC/AC ratio for a solar inverter?

Because the PV array rarely produces power to its STC capacity, it is common practice and often economically advantageous to size the inverter to be less than the PV array. This ratio of PV to inverter power is measured as the DC/AC ratio. A healthy design will typically have a DC/AC ratio of 1.25.

Thus a 9 kW PV array paired with a 7.6 kW AC inverter would have an ideal DC/AC ratio with minimal power loss. When the DC/AC ratio of a solar system is too high, the likelihood of the PV array producing more power than the inverter can handle is increases.

What happens if a PV inverter loses power?

In the event that the PV array outputs more energy than the inverter can handle, the inverter will reduce the voltage of the electricity and drop the power output. This loss in power is known as “clipping”. For example, a DC/AC ratio of 1.5 will likely see clipping losses of 2-5%. Not as major as other losses, but still a noticeable effect.
