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.
Table 17.1 Recommended inverter sizes for different locations. The nominal power of the inverter should be smaller than the PV nominal power. The opti-mum ratio depends on the climate, the inverter efficiency curve and the inverter/PV price ratio. Computer simulation studies indicate a ratio P (DC) Inverter/PPV of 0.7 - 1.0.
Thus the nameplate rating of the inverter is its capacity to process the power of the PV array. For example, a 7.6 kW inverter can produce an output of up to 7.6 kW AC. A 9 kW DC solar array rarely produces this much power.
A 1:0.8 ratio (or 1.25 ratio) is the sweet spot for minimizing potential losses and improving efficiency. DC/AC ratio refers to the output capacity of a PV system compared to the processing capacity of an inverter. It’s logical to assume a 9 kWh PV system should be paired with a 9 kWh inverter (a 1:1 ratio, or 1 ratio).
When designing a solar installation, and selecting the inverter, we must consider how much DC power will be produced by the solar array and how much AC power the inverter is able to output (its power rating).
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.
