Its main function is to control the charging and discharging process of the battery and perform AC / DC conversion to meet the transmission and distribution needs of the power system. The energy storage inverter generates a lot of heat when working, which causes the internal temperature of the energy storage inverter to rise. The high temperature of the internal electronic components will affect its working efficiency and service life. Secondly, in daily use, dust is easily accumulated at the dust screen of the air inlet of the energy storage inverter, which will also affect the heat dissipation effect.
