The relationship between inverter efficiency and power is defined by the ratio of AC output power to DC input power. Inverter efficiency indicates how effectively the inverter converts DC power into AC power, typically ranging from 85% to 95%2. If the load power exceeds the inverter's rated power, it can lead to inefficiencies or damage3. Therefore, maintaining an appropriate balance between the inverter's power capacity and the load demand is crucial for optimal efficiency4. [pdf]
