7 Commissioning
7.1 Basic Configuration of the Sunny Island Inverter
Requirements:
☐ The SMA Flexible Storage System must be installed in accordance with the circuitry (see Section 4.1 or 5.1).
☐ With a three-phase system, the Sunny Remote Control must be connected to the master. The master is thus defined
during basic configuration.
☐ The circuit breaker F1 in the distribution board must be open.
Procedure:
Damage to the battery due to incorrect settings
The set battery parameters influence the charging behavior of the Sunny Island inverter. The battery can be damaged
by incorrect settings of the parameters for battery type, nominal voltage, and capacity.
• Ensure that the values recommended by the battery manufacturer are set (refer to the technical data of the battery
in the manufacturer documentation). Note that the battery charging behavior names used by
SMA Solar Technology AG and the battery manufacturer may, in some cases, differ in meaning (for the battery
charging behavior of the Sunny Island inverter, see technical information "Battery Management").
• Set the battery capacity for a ten-hour electric discharge (C10) The battery manufacturer specifies the battery
capacity in relation to discharge time.
Check the wiring (see the Sunny Island inverter installation manual).
Close all devices except the BatFuse.
This protects all live components from being touched.
Close the BatFuse and switch on all Sunny Island inverters:
In systems with one Sunny Island, press the "On" button.
In systems with three Sunny Island inverters, press and hold the "On" button on the master until an acoustic signal sounds.
