Testing automatic backup operation

Requirements:

  • The automatic transfer switching device for automatic backup operation must be connected.

  • The inverter must be commissioned (see product manual).

  • The Automatic backup operation parameter must be configured during commissioning.

  • Parallel grid operation must be configured.

  • The battery must be sufficiently charged or there must be sufficient PV energy available.

Procedure:

  1. To simulate a grid failure, switch off the central miniature circuit breaker (pre-meter fuse) or the fuse of the automatic transfer switching device in the Main Panel.
  2. Wait for the time set in the parameter Operation.BckSwOnDl (Minimum duration of grid fault for start of automatic backup operation).
  3. The automatic transfer switching device switches to automatic backup operation with an audible click.
  4. When the time set in the parameter Operation.BckSwOnDl (Minimum duration of grid fault for start of automatic backup operation) has elapsed, all loads in the automatic backup circuit should be supplied with electric current.
  5. Switch on the central miniature circuit breaker (pre-meter fuse) in the junction box again.
  6. Wait for the time set in the parameter Operation.BckSwOffDl (Minimum duration of grid recovery for deactivation of backup operation).
  7. The automatic transfer switching device switches to parallel grid operation with an audible click.
