Conversion efficiency of household inverter refers to the efficiency of converting electricity from solar panels into electricity. Two key factors affecting the efficiency of household inverters are as follows:

1. When converting DC current into AC pure sine wave, the DC current needs to be switched by using power semiconductor circuit. At this time, the heating of power semiconductor will lead to loss, but by improving the design of switching circuit, the loss can be minimized.

2. Improve the efficiency by the control experience of the inverters. The output current and voltage of solar panel will change with the sunshine and temperature. Inverter can control the current and voltage optimally to maximize the power output. That is to say, the shorter the time to find the optimal power point, the higher the conversion efficiency will be. The control characteristics of the inverters vary with the manufacturer's products and their conversion efficiency. For example, some inverters have high conversion efficiency at the maximum power output, but low conversion efficiency at the low power output; others maintain average conversion efficiency from the low power output to the high power output. Therefore, the matching between the output characteristics of the solar panel and the inverters should be considered when selecting the inverters. Every 0.1 percentage point increase in the efficiency of household inverters implies a lot of hard work of R&D personnel, which needs to tackle various technical problems in R&D, testing and other aspects, representing the current industry's highest level of efficiency is hard to come by. Starting with the design details from many aspects, we can guarantee the income of photovoltaic power plant investors.
