How Many Amp-Hours Do I Need for Boondocking?

Add watt-hours for each load, subtract realistic daily charging, multiply by days and reserve, then convert to amp-hours at system voltage.

WeRV Power answer

Convert appliance use into daily watt-hours and size a battery bank with charging and reserve.

What to verify

Use the result as a planning range. Exact fitment and installation must be checked against the vehicle, equipment and selected battery manufacturer.

  • Watt-hours = watts × hours
  • Account for inverter efficiency
  • Use realistic solar production
  • Choose usable-depth assumptions from the battery maker
ADVANCED OPTIONS

Build around how you actually use your battery.

Choose this path when you know your system voltage, daily energy use, cart configuration or accessory load.
