3. Check the strings for ground faults, as described in section 12.1 „Ground Fault Monitoring”
(Page 67).

Ensure that the strings are assigned correctly (as
described at the beginning of the section). Unused
DC input sockets must be sealed with caps.

NOTICE!
The Sunny Boy could be irreparably damaged by overvoltage!
If the voltage of the solar modules exceeds the maximum input voltage of the Sunny
Boy, it could be irreparably damaged by overvoltage. All warranty claims become
void.
• Do not connect strings to the Sunny Boy with open circuit voltage greater than
the maximum input voltage of the Sunny Boy.
• Check the system design.
DANGER!
Risk of lethal electric shock!
A hazardous electric arc can form if the DC plug connector is removed without first
removing the Electronic Solar Switch.
• Operate the Sunny Boy only when the lid is closed so that the DC plug
connectors cannot simply be removed.
• Do not plug in the Electronic Solar Switch until the lid is closed.
