5.7.2 Setting to Stand-alone Grid Operation
To operate the inverter in an stand-alone system with Sunny Island, you must set the inverter via the
"Default" parameter to stand-alone grid operation ("OFF-Grid").
There are several ways of setting the inverter to stand-alone grid operation:
• Setting via Sunny WebBox
or
• Setting via Sunny Data Control or Sunny Explorer
DANGER!
Danger to life due to high voltages in the event of electricity grid failure
If you set the inverter to stand-alone grid operation, it does not fulfil any country-specific
standards or guidelines. If grid failure occurs, there will consequently be a danger of
backfeed.
• Never operate the inverter directly on the electricity grid when set to stand-alone grid
operation.
