WARNING

Danger to life due to fire

In case of a short circuit, the short-circuit current driven by the generator flows over the unprotected cable between the Sunny Island and the AC distribution board. Short-circuit currents can cause fires.

  1. If the fuse on the generator has a higher operating current than the fuse in the AC distribution board, size the cable between the generator and AC distribution board in accordance with the operating current of the fuse on the generator.

Requirement:

  • The inverters to be connected must be Sunny Island 6.0H / 8.0H inverters.

Procedure:

  1. Connect the AC power cable to the AC2 Gen/Grid on all Sunny Island. When doing so, connect the line conductor to AC2 Gen/Grid L and the neutral conductor to AC2 Gen/Grid N( > Connecting the AC Power Cable).
  2. Thread the grounding conductor through a ferrite included in the scope of delivery and connect to AC2 Gen/Grid PE ( > Connecting the Grounding Conductor).
