7.2
Commissioning the Inverter
Requirements:
• All circuit breakers in the AC distribution board must be open.
• All Sunny Island inverters must be connected correctly (see Section 6.7, page 63).
• All inverters must be closed (see Section 6.8, page 66).
• All Sunny Island inverters must be switched off.
• The fuse switch-disconnector of the battery fuse must be closed (see Section 6.9, page 67).
Procedure:
1. For systems with 1 Sunny Island, press the "On" button.
2. For systems with 3 Sunny Island inverters, press and hold the "On" button on the master until an acoustic signal
sounds.
3. For multicluster systems, press and hold the "On" button on each master until an acoustic signal sounds.
4. Establish a connection to the user interface of the inverter (see Section 8.1, page 104).

Performing Basic Configuration of the Installation Assistant
Standard configuration of single-cluster and multicluster systems
In single-cluster systems, the master captures all user input. The slaves wait in standby mode for the start command
from the master.
In multicluster systems, the master of the main cluster captures all user input and sends it to the master of the
extension clusters. The masters of the extension clusters wait in standby mode for the start command from the
master of the main cluster.
