Once the mains supply is restored and stabilized, the panel automatically switches the load back to the mains and stops the generator.

Key Functions:

• Automatic detection of mains failure
• Auto start/stop of DG set
• Automatic load transfer (changeover)
• Protection against overload, short circuit, and phase failure
• Time delay settings for safe operation

Main Components:
