How much power does an inverter use on standby
For a 1000W inverter, the average idle power consumption could be around 10-20 watts, while for a 2000W inverter, it could be
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.
The amount of power drawn from a battery by an inverter, even when there is no load attached, is called the "idle" or "no-load" consumption of the inverter. The average draw from the batteries when an inverter is turned on with no load attached depends on the efficiency of the inverter and its standby power consumption.
It is an important question especially if you are doing everything possible to save energy and dollars. An inverter will draw power even without a load. This is known as a no load current although the energy drawn is only 2 to 10 watts n hour. The no load current is listed on the inverter specifications sheet.
Different inverters operate optimally at different input voltages. If the battery voltage is lower than the inverter's rated voltage, it may draw more power to maintain the desired output. For instance, a 12V inverter operating on a 10.5V battery may increase power draw inconsistently, reducing efficiency.
