7.1 Basic Configuration of the Sunny Island Inverter
Requirements:
☐ With a three-phase system, the Sunny Remote Control must be connected to the master. The master is thus defined
during basic configuration.
☐ In the automatic transfer switch, all circuit breakers must be open. This means that the Sunny Island is not connected
to any PV inverter.
Procedure:

Damage to the battery due to incorrect settings
Aging of the battery will be accelerated by incorrect settings of the parameters for battery type, nominal voltage,
and battery capacity. The battery parameters influence the charging behavior of the Sunny Island inverter.
• During the basic configuration, ensure that you configure the battery values recommended by the battery
manufacturer (for the battery technical data, see the documentation of the battery manufacturer).
• In the basic configuration, configure 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.
