The conversion efficiency of photovoltaic inverter is required to be high, and the conversion efficiency will directly affect the amount of power generation in the life cycle of solar power generation system. According to different models, the highest conversion efficiency of world-class brand products can reach more than 98%. The conversion efficiency of high-power photovoltaic inverter can reach 98.7%, and the maximum power tracker (MPPT) efficiency can reach 99.9%.

Photovoltaic inverter has long service life and high reliability. The design life of photovoltaic power generation system is generally about 20 years, so the design life of photovoltaic inverter needs to reach a higher level. At the same time, the failure of photovoltaic inverter will lead to the shutdown of photovoltaic power generation system and bring economic losses, so high reliability is an important technical index of photovoltaic inverter.
