Efficiency of Inverters The efficiency of an inverter indicates how much DC power is converted to AC power. Some of the power can be lost as heat, and also some stand-by power is consumed for keeping the inverter in powered mode. The general efficiency formula is: where P AC is AC power output in watts and P DC is DC power input in watts.
In general, the efficiency of a PV inverter is a function of the input power and input voltage, with a typical set of efficiency curves being shown in Fig. 1.4. At medium to high light levels and therefore input power from the array, the inverter has a high efficiency, generally well in excess of 90%.
It depends mainly on the power and can also be a function of the input voltage. In PVsyst there are 4 ways of defining the efficiency of inverters : from a set of 3 efficiency curves eff = f (Power, input voltage), all of them automatically built from the Maximum, EURO or CEC efficiencies and Pthresh.
In Figure 8a, the input range is 250VDC–500VDC and the outputs are 208/240/277 VAC. Inverters can have better efficiency at a higher voltage because the current is reduced and therefore voltage drop and heat are reduced.
