Technical FAQs 4

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 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 a 1500 watt inverter draw?

A 1500 watt inverter with a 500 watt load would be 50 (25) Amps, not 150 (75) Amps. The same inverter with a 1200 watt load would draw 120 (60) Amps, which would be the same amount as a 1200 watt inverter at load capacity. A 2000w 12v pure sine wave inverter draws power based only on its load.

How do you calculate dc current from an inverter?

To calculate the DC current draw from an inverter, use the following formula: Inverter Current = Power ÷ Voltage Where: If you’re working with kilowatts (kW), convert it to watts before calculation: Inverter Current = 1000 ÷ 12 = 83.33 Amps So, the inverter draws 83.33 amps from a 12V battery. Inverter Current = 3000 ÷ 24 = 125 Amps
