Off-the-Grid Power Consumption

Posted by Home Energy on February 22, 2007

Question for the Editors

Could you please answer a question for me? Living off the "grid", am I better off using flourecent 12 volt dc lights or 120 volt ac flourecent lights through my inverter?

Ohm's law seems to say I will use less power through the inverter, with a 26 watt 120 volt light using .2166 amps with a .5 amp inverter draw for a total of .7166 amps, and a 26 watt 12 volt DC light drawing 2.166 Amps. Somehow logic tells me this has to be wrong. What am I missing?

Thank you for any help you can give me.
