FAQ – Battery planner

  • Why 380 Volt input ?
    • In a 3 phase System 380V gives 240V from phase to neutral on each phase. This is the most common configuration in countries with 240V supply as standard.
  • Why 100A/hr batteries ?
    • This is the most common format for automotive and general purpose applications, and is easy to both acquire and handle. Larger sizes are possible, but get heavier and therefore harder to handle.
  • What is autonomy time ?
    • The time in minutes that the UPS is expected to supply power at full load if the utility supply fails
