    What kind of panel? Breaker panels for AC and DC power, solar panels?

    If solar panels, where will it be installed (nearest largest city). Clear of trees (no shade) at least 9am to 3pm?  How much energy per day do you need (Amp*Hours or Watt*Hours)? Full time off grid all year round or just weekends and sunny/non-winter visits?

    wildaxle,
    At 24 volts, it's very likely the 250 amp model. Your inverter manual will state the necessary DC breaker size.

    Agree with Rick but your calculation for system amp hours is off the mark according to what you wrote.
