during commissioning.
Prerequisites
The SMA Sunny Island has been installed in accordance with SMA’s specifications (installation/connection).
Procedure
1
Check the wiring of the SMA Sunny Island and TS 48 V (see the operating manual for the
SMA Sunny Island).
2
Check the wiring of the components in accordance with section “5.9 Wiring the battery modules” on page
21 et seq. If the wiring is correct, all live components will be protected against physical contact.
