Complete Commissioning.
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
will be displayed on the Sunny Island user interface.
Procedure:
1. Make sure that the wiring is correct (see Section 6.7, page 63).
2. Ensure that all system-specific preparations for commissioning have been implemented correctly ( see system
description Sunny Island system used).
3. Connect the circuit breakers and fuse switch-disconnectors for the 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. Start the Sunny Island system (see Section 9.2, page 118).
6. With off-grid systems only, when full charge is complete, switch on all circuit breakers and load-break switches.
7. In order to receive service assignments for the Sunny Island system, all system data must be recorded in the
information sheet for Sunny Island systems and made available to Service (for information sheet see www.SMA-
Solar.com).
