7 Commissioning SMA Solar Technology AG
42 Off-Grid-IS-en-30 Installation - Quick Reference Guide
7.7 Commissioning the Sunny WebBox
• Commission the Sunny WebBox (see the Sunny WebBox quick reference guide).
7.8 Commissioning the PV System
For operation in an off-grid system, the PV system must be configured for stand-alone mode.
Procedure:
1. Commission the PV system (see PV inverter documentation).
2. If the SMA PV inverters are not configured for stand-alone mode ex works, configure the country standard or country
data set of the PV inverters for stand-alone mode (see the PV inverter documentation).
7.9 Completing Commissioning
1. On the Sunny Remote Control, adjust the configuration to the system (see the Sunny Island inverter installation
manual). This way, you can increase the service life of the battery, for example.
2. When full charge of the battery 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 corresponding entries in the 400# Failure/Event menu.
