Do not confuse the inverter's no-load current with the efficiency rating of the inverter.
How much power does a 24V inverter draw?
To find out how much power an inverter draws without any load, multiply the battery voltage by the inverter no load current draw. A 1000 watt 24V inverter with a 0.4 no load current has a power consumption of 9.6 watts. 24V x 0.4 = 9.6 watts If you want to figure out the no load current in amps, divide the watts consumption by the battery voltage.
