Deep Cycle Battery Sizing Calculator

Calculate the battery bank size (Amp Hours) needed to run your appliances during a power outage, camping trip, or for an off-grid solar system.

Key Considerations

  • Inverter Efficiency: We assume ~85% efficiency, meaning you need more battery power than your load simply consumes to account for conversion losses.
  • Depth of Discharge (DoD):
    • Lead Acid (AGM/Gel): Should not be discharged below 50% to ensure longevity.
    • Lithium (Li-ion/LiFePO4): Can safely be discharged to 80-90%.
