    Ballpark figure how long could I run the fan via a 100 watt inverter hooked up to 2 110 amp batteries renewed by solar ?
    Would it last a night ?

    80W at 12V = 7A.
    110 AH / 7 = 15 H

    I'd be surprised if a 100W inverter will start an 80W fan and probably won't run it. Starting load on a fan is at least 3 x running load. Add in power factor and I don't think it'll do it.

    You of course are already doing it and I'm a liar:)

    But only if you want to kill your battery.

    Just under 8hrs to 50% discharged.

    ... he's got 2 x 110 amp batteries = 220 amps, so 50% is 110 amps

    :doh: I didn't read the whole first post, my reply was to Brian's reply which stated 110 ah.

    As my teachers said....must try harder.
