Inverters can have better efficiency at a higher voltage because the current is reduced and therefore voltage drop and heat are reduced. Inverter input voltage depends on input from batteries or sources such as PV arrays or wind turbines.
Often, inverter rated efficiency is the primary factor used to determine system performance, but this can be misleading. Efficiency changes with DC input voltage, AC output voltage, the percentage of rated load supplied, and other factors.
From the results of the two analyses, it can be concluded that the G2 inverter, connected to p-Si PV modules (see Fig. 3), has the maximum efficiency at 0.91 because the input voltage and frequency distribution of between 230–250 V DC was the most suitable and preferable voltage range for this inverter.
The only way to improve the efficiency of power inverters is to reduce the losses. The main losses of inverters come from IGBT, MOSFET and other power switch tubes, as well as magnetic devices such as transformers and inductors, which is related to the current, voltage and the process adopted by the selected materials.
The efficiency of the inverter may vary depending on the input power and voltage of the PV array. The nominal efficiency is indicated in the manufacture specifications and is the value during operation in the nominal inverter voltage range and at a partial load of about 50%–80% of nominal power.
Finally, the maximum efficiency of an inverter, determined from a PV input voltage at an irradiance of above 350 W/m 2 (the inverter operating with the highest average efficiency), showed that the voltage of 230–240 V DC was the best voltage range (see Fig. 11).
