About Inverter Battery Systems

Inverter battery systems provide backup power during outages. Proper sizing ensures adequate backup time while optimizing cost and battery life.

Key Considerations:

  • Depth of Discharge: Affects battery life and capacity
  • Inverter Efficiency: Impacts actual power consumption
  • Safety Factor: Accounts for aging and temperature effects
  • Battery Type: Lead-acid, AGM, or Lithium technologies

Battery Types:

  • Lead-acid: Cost-effective, 50-80% DOD
  • AGM: Maintenance-free, 80% DOD
  • Gel: Deep cycle, 80% DOD
  • Lithium: High efficiency, 90% DOD
