Off-grid power calculators
Start with the power station calculator to find your daily energy use. Then carry that number into the solar or runtime tools.
Step 1
Power station size calculator
Device list → daily Wh, recommended capacity, continuous and surge watts.
Step 2Solar panel size calculator
Daily Wh + peak sun hours → panel watts and recharge time.
AnytimeBattery runtime calculator
Capacity in Wh or Ah + load in watts → hours of runtime.
ConvertWatts ↔ amps calculator
Watts or amps + voltage → the other, with power factor and inverter current.
AnytimeAh ↔ Wh converter
Amp-hours or mAh + voltage → watt-hours, and back.
CostElectricity cost calculator
Watts or yearly kWh + your rate → cost per day, month and year.
Wiring12 V wire size calculator
Current + cable length → wire gauge (AWG), voltage drop and fuse range.
