I have a question today about inverters.
if i have a 12 volt in, 120 volt out 600 watt inverter, what is the input?
is the input 5 amps or 50 amps?

Output 600 watts or 5 amps at 120V.
Input 600 watts, or 50 amps plus at 12 V.

Unless you have the specific efficiency factor for your inverter, use 85%. So your actual draw on the batteries will be somewhere around 57.5 amps at full load.
