Abstract：
Inverter is an important equipment in photovoltaic power generation system and often malfunctions when inverter ventilation and filtration system can not meet the requirements. Elaborates the classification of heat removal methods, the common heat removal methods, selection of air intakes and exhaust outlets, air intakes filtering measures and problems in the heat removal. Optimizes air intakes filtering measures, in order to reduce inverter failure and improve economic efficiency.
