[0002] As the key element in photovoltaic power generation system, photovoltaic inverter can convert the variable DC voltage generated by photovoltaic solar panel into AC power of commercial power frequency. The converted AC power can be fed back to commercial power transmission system to realize power grid connection and supply power to users, or used in off-grid power grid to meet the power demand in specific scenarios. In the whole photovoltaic power generation process, inverter plays an irreplaceable role.

[0003] However, inverter is exposed to outdoor complex environment for a long time, and is prone to failure due to wind, sunlight, temperature change, humidity and other factors.
