Technical FAQs 4

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.

How much power does an inverter use?

The more modern the inverter, the more power you save. A 90% efficient inverter means it requires 10% more power than what its load requires. If you run a 300 watt load for instance, the inverter will need 330 watts. With larger inverters the drain could be up to 2 amps even a load.

How much battery does a 24 volt inverter use?

For 24-volt inverters, it is 10 %. The battery capacity for a 12-volt Mass Sine 12/1200, for instance, is 240 Ah, while a 24-volt Mass Sine 24/1500 inverter would require at least 150 Ah. The indicated battery capacity is only for the inverter. The capacity required for other loads should be added to it. How much power does an inverter consume?

Does an inverter draw power without a load?

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.
