Be aware that the size of your battery bank should play a part in your decision of what size inverter to buy. A 600 watt inverter at its full rating will draw 50 plus amps. If you have a single battery, it will be down to 50% in less than one hour. If only drawing less than 300W, a 300W inverter will be more efficient than the 600W inverter.
Inverter max efficiency is around 1/2 -3/4 of its watts rating so if you are maxing a 300w it might not draw any more amps than the 600w would.
I find the "divide by 10" rule works closely. So a 1000w draw would demand 100 amps from the battery.
( I am still using tenbear's voltage drop calculator and the conversion table of voltage for temp comp wrt 77F. Most useful, thanks again! :) )
