Electrical Load Evaluation is a great link to bookmark.
http://www.absak.com/design/load.html
At bottom of page a link to load calculation form in pdf file.
Remember to multiply AC appliance’s wattage time’s 1.15 equal inverter loss wattage.
At bottom/right of form is total wattage that including load correction factor
And have "Power Consumption Table"
FWIW

ok, i plugged in the numbers and i figure i need about 2400 watts a day. how does that equate in to amp hours? |

Morgan
Volts x Amps = Watts
at 12V = 200 AH x 1.15 (inverter) = 230AH
at 24V = 100 AH x 1.15 (inverter) = 115 AH
Avoiding depletion of greater than 50% (best for battery life) bank must be twice the AH capacity between charging events. |

Morgan, to answer your question, if you have 12 volts, you should have 4,800 watt hours of capacity, which means 400 amp hours. That would require 4 golf cart batteries.
If you have 24 volts, the same 4 golf cart batteries in a different configuration would be needed.
Golf cart batteries are 1.3 kwh of capacity per, which means that you really should only use about 1/2 kwh per between charges.
For what it's worth.
