Hello, I just came across this site when looking for some info. Not sure if this is a stupid question but I would like to know what the correlation between AC and DC power is when comparing one device. For example if i had a a device connected to 120vac and it drew 500w then the amps would be 4.16. So if i use that same device and connect it to a power inverter on a 12vdc system, it would draw that same power through the inverter, but what would be the draw on the 12vdc side? Is it just simply 500w/12v=41.6amps. I am basically trying to figure how much AC power can be drawn from a 12vdc battery where 50a is the max current the can go through a dc meter. Thank you
