The formula to calculate the current draw in amperes is: Current (Amps) = Input Power (Watts) / Battery Voltage (Volts). Continuing the previous example, if your inverter draws 1111 watts

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

The inverter current calculator helps you find the current drawn from the battery and the current supplied to your appliances.

For example, a 1,000W inverter (and supplying 1,000W to AC devices) divided by 10 = 100A of battery current required - this is a rough, rounded-up way of calculating inverter/battery

If you have a 230 watt load on a 12V inverter, the inverter draws 19.1 amps (230 / 12 = 19.1). With a 24V system the draw will drop to 9.5 amps (230 / 24 = 9.5).

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.

QUICK: Divide watts by 10. For example, your 240V appliance shows a rating of 300W. This appliance will draw 30A from your 12V batteries when running through an inverter. Watts are Watts and remain

In general, a 1500 Watt inverter running on a 12V battery bank can draw as much as 175 Amps of current. A 1500W inverter running on a 24V battery bank can draw up to 90 Amps of

Inverters with a greater DC-to-AC conversion efficiency (90-95%) draw fewer amps, whereas inverters with a lower efficiency (70-80%) draw more current. Note: The results may vary
