9 Commissioning
Prerequisites:
The SMA Flexible Storage system must be installed according to the interconnection diagram specified by SMA
The Sunny Island power circuit breaker in the distribution system must be open
In a 3-phase system, the Sunny Remote Control must be connected to the Master
Procedure:
Check the wiring of the SMA and battery. See the Sunny Island Installation Instructions from SMA
Close all components. This protects all live components from accidental contact.
Close the DC fuse in the Bat Fuse (if used).
Press the on/off switch on the APU. The battery’s initiation mode (INIT) will commence. Tap the screen on the battery to
activate the display. The number of recognized battery modules will be displayed on the screen. If this is correct,
confirm by tapping twice. Otherwise check the BAT COM cabling.
Once the number of battery modules has been confirmed, the light on the switch will begin to flash. The battery is now in
pre-charge mode (PRECHG). Once pre-charging has completed, the light on the switch will remain on. On the battery
display, the status will be indicated as OK. Now the battery is ready for use.
For systems with one Sunny Island, press the power button. For systems with three Sunny Islands, press and hold the
power button on the master until you hear a signal tone.
WARNING!
Battery damage may occur due to incorrect configuration. The parameter settings influence the charging behaviour of
the Sunny Islands. It is therefore important to make the correct settings before commissioning the system.
