Peak efficiency (often promoted in data sheets) is not a helpful value since most of the time the inverters operate in the range of 20% to 40% of their rated power – at least under non-arid
The efficiency of an inverter, which determines how much of the DC power generated by a solar array is converted to AC power, is generally not a fixed value. Instead, this parameter varies with input DC power and voltage, and the amount of variation is specific to the inverter.
Below 10-15% of power output, efficiency is quite low. At high output power, the efficiency is steadily high with some small variations. The behavior in Figure 11.8 partially results from the fact that stand-by losses for an inverter are the same for all output power levels, so the efficiency at lower outputs is affected more.
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. High quality sine wave inverters are rated at 90-95% efficiency.
In general, the technical information for a PV inverter will include both the peak efficiency (usually between 95% and 98% depending on the inverter technology) and a weighted efficiency to account for the operation at different irradiance levels.
