An inverter draws power from a battery depending on its efficiency, typically over 92%. For a connected load of 250 watts, the inverter uses less than 270 watts from the battery. This value includes energy conversion losses. Understanding inverter specifications helps optimize power consumption and battery voltage for better performance.
Efficiency of Inverters The efficiency of an inverter indicates how much DC power is converted to AC power. Some of the power can be lost as heat, and also some stand-by power is consumed for keeping the inverter in powered mode. The general efficiency formula is: where P AC is AC power output in watts and P DC is DC power input in watts.
Inverter efficiency directly affects power draw from a battery. An inverter converts direct current (DC) from a battery into alternating current (AC) for appliances. The efficiency rating of an inverter indicates how much of the input DC power is successfully converted into usable AC power.
where P AC is AC power output in watts and P DC is DC power input in watts. High quality sine wave inverters are rated at 90-95% efficiency. Lower quality modified sine wave inverters are less efficient - 75-85%. High frequency inverters are usually more efficient than low-frequency. Inverter efficiency depends on inverter load.
