Good heat dissipation design, up to 120% overload capability

• Good heat dissipation design: the air flows into the inverter from the frontside and flows outof the inverter from the backside. The inverter can be installed against the wall, to reduce the

length of the air duct and increase the heat dissipation efficiency• Strong overload capability: up to 120% overload capability can be achieved under 50℃; while

derate according to the curve above 50℃
