Solar PV Inverter Sizing Calculations. The process of inverter sizing involves understanding the relationship between DC (Direct Current) from the solar panels and AC (Alternating Current) required for powering appliances. The Inverter Sizing Formula is – AC Inverter Capacity (kW) = DC Input Power (kW) / Inverter Efficiency (%).

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). But that’s not the case.

solar PV. The system with an inverter, will need to produce 19.2 ac kWh per day. This value will be divided by the average peak sun-hours (PSH) for the geographic location. System losses (derate factors) will be applied. The final value is the calculated solar PV array size in kilo-watts.

Iterate your DC/AC ratio at scale. You can use RatedPower to dimension both the PV plant DC power and the inverters AC power.
