2.3.2 Work principle
If the arc fault is detected, the product will issue an alarm signal by the indicator
and Email. At the same time, the AC relay will be driven to break off the AC circuit
between the inverter and the grid. So that the inverter will stop working to ensure that
the DC circuit is in the state of no current. After 2 minutes, the AC relay will be
driven to turn on the AC circuit and then the entire circuit resumes normal operation.
