30 Off-Grid-IS-en-30 Installation - Quick Reference Guide
5.5 Basic Configuration
Requirements:
☐ The off-grid system must be installed according to the circuitry (see Section 5.1, page 24 and Section 5.2, page 25).
☐ All device enclosures must be closed except for the BatFuse. This protects all live components from being touched.
☐ All circuit breakers in the AC distribution board must be open. Thus, the Sunny Island is not connected to an AC
source.
☐ The Sunny Remote Control must be connected to the master. This determines which Sunny Island is the master during
the basic configuration.

Damage to the battery due to incorrect settings
The 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 for the battery during basic configuration
(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 press and hold the "On" button on the master until you hear an acoustic signal.
When the Sunny Remote Control shows ,
press and hold the button on the Sunny Remote Control.
☑ An acoustic signal sounds three times and the
Sunny Remote Control displays the Quick Configuration Guide.
