The current depends on the power output required by the load, the input voltage to the inverter, and the power factor of the load. The inverter draws current from a DC source to produce AC power.

The current draw from a 12V or 24V battery when running an inverter depends on the actual load, not the inverter size. A quick rule is to divide watts by 10 for 12V systems or 20 for 24V systems.

If you have a 1,000W 12V inverter, you can expect it to use between 88 and 105 Amps. If your inverter is 1,000W but 24V, you can expect it to use between 44 and 52 Amps. A 1,000W 48V inverter uses

For example, to provide a service of 15 Amperes at 120 Volts AC (1800 Watts) from a 12 Volt battery, the DC current will approach 180 Amperes! How can we supply such a high current to the inverter safely

For a 12 V inverter such as a Mass Sine 12/1200, consumption will be 400/10 = approx. 40 amps. For a 24 V inverter, say a Mass 24/1500, the corresponding figure is 400/20 = approx. 20 amps.
