Understanding DC/AC Ratio

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. The reason for this is that about less than 1% of the energy produced by the PV array throughout its life will be at a power above 80% capacity. Thus a 9 kW PV array paired with a 7.6 kW AC inverter would have an ideal
