[QUOTE="p238shooter, post: 2684803, member: 24583"] You might want to look at the power requirements of the fan motor(s) you will need to run. Volts (110) times the amperage draw of your motor will equal the wattage consumed. Take that wattage and divide it by 12 volts and that will be a little less than the current draw out of your battery. The inverter will have some loss because it will not be 100% efficient. For example: a 110 volt small fan motor drawing 1 amp would consume 110 watts. On a 12V battery powered inverter it will still draw 110watts now divided by 12V which equals 9.2 amps plus a little loss, so figure about 10 Amps. A standard deep cycle marine battery might realistically give you 5-6 hours runtime before a recharge is needed. A small generator outside with a couple long cords might be a more efficient option for your furnace fan, and you could touch up your refrigeratorand freezer a couple hours each day, run a coffee pot, microwave, and have a table light if you wanted. Keep us updated on how you make it work. [/QUOTE]
