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.

Here is the table showing how many amps these inverters draw for 100% and 85 % efficiency. In reality, inverters have some efficiency losses, and the actual amp draw might be slightly higher.

16.6 amps at 120vac will be about 166 amps from a 12 volt battery. For a 2000 watt inverter 200 amp discharge rate would be minimum battery rating and closer to 300+ I recommend.
