# Quick Answer: What Size Battery Do I Need For A 1500 Watt Inverter?

## How many amps does a 1500W inverter draw?

Notes on wattage rating vs load: So 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..

## What will a 1500 watt inverter run?
