Chris Couture (9/11/2008)Lets look at Ohm's law...
300 watts at 120 volts = 2.5 amps or current needed....
To bump up 12 volts to 120 volts would requires 10 times the amp draw so it would take 25 amps of 12 volts to run one 300 watt light.
Multiply that by 4 and you have got 100 amps needed to run 4-300 watt 120v lights.
I don't think one battery will last you long with a 100 amp draw on it...
Just my opinion....

and thats assuming the invertor is 100% effiecient
