8.8 Completing Commissioning

1. Make sure that the wiring is correct (see Section 7.6, page 62).
2. Ensure that the functional test has been carried out (see "Installation - quick reference guide" of the system used).
3. Connect or close the circuit breakers and fuse switch-disconnectors for energy sources.
4. With off-grid systems only, disconnect or open all loads, the circuit breakers of the loads and the fuse
switch-disconnector. As a result, only the energy sources are connected to the Sunny Island.
5. Press the start-stop button on the Sunny Island and hold it until an
acoustic signal sounds.
☑ The Sunny Island starts charging the battery automatically.
6. With off-grid systems only, when full charge is complete, switch on all circuit breakers and load-break switches.
Tip: The state of charge of the battery is displayed on the Sunny Remote Control in standard mode.
Load shedding in the first two operating hours
The state of charge (SOC) recorded by battery management and the available battery capacity (SOH) will
deviate strongly from the actual values of SOC and SOH for a newly connected battery. During operation, the
values recorded by battery management will gradually approach the real values. In the first two operating
hours with the new battery, these deviations can lead to load shedding and corresponding messages. These
messages are shown on the Sunny Remote Control or communication product (see the Sunny Island operating
manual or the user manual of the communication product).
