Stand-alone operation detected

What does 108 mean?

The inverter has detected an unintentional stand-alone operation (island mode), meaning it is operating independently from the main grid. This is typically a safety mechanism to prevent unsynchronized grid reconnection.

• Inverter operating in an unintended island mode
• Poor or intermittent AC grid connection leading to grid isolation detection
