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%.
No inverter is 100% efficient—some energy always gets lost as heat during the conversion. Most modern inverters have efficiency ratings between 90% and 98%. Let’s break it down: If you feed 1000 watts of DC power into your inverter and it outputs 950 watts of AC power, your inverter efficiency is 95%.
The type 1 inverter presents a lower efficiency for small load (<30%), type 2 has the best efficiency whatever the percentage of load. Finally, the efficiency in type 3 decreases for high percentage of load in a more important way than for the two other types. 2017, The Performance of Photovoltaic (PV) System N.M. Pearsall
