What it shows

  • Grid AC continuously converts to DC, then back to pristine load AC.
  • Battery float-charges on internal DC bus, providing seamless instant power.
  • Static bypass switch handles internal component failures in sub-millisecond.

The takeaway

Online double-conversion guarantees clean power with 0ms interruption by running the inverter full-time.
