Starting the System

Start inverter via user interface

Starting the inverter via the user interface is an alternative to pressing the start-stop button.

  1. To start the inverter via the user interface, set Device parameters > Device > Operation > General operating mode to Start.

Requirements:

  • All Sunny Island inverters must be switched on.
  • The circuit breakers for the AC sources in the stand-alone grid must be switched off in the AC distribution board.
  • The load-break switch of the PV array must be open.

  1. For systems with 1 Sunny Island, press the "start-stop" button on the Sunny Island until an acoustic signal sounds.

  2. Start of a single-cluster system

    When starting a single-cluster system, the slaves wait for the start command from the master.

    1. For systems with up to 3 Sunny Island inverters, press and hold the "start-stop" button on the master until an acoustic signal sounds.

  3. Starting a multicluster system

    When starting a multicluster system, the extension cluster masters wait for the start command from the main cluster master.

    1. For multicluster systems, press and hold the "start-stop" button on the master of the main cluster until an acoustic signal sounds.
  • The inverter LED on each Sunny Island is glowing green. The Sunny Island inverters are in operation.
