Protect your PV system with Projoy PEFS Firefighter safety switch.
If the temperature exceeds +70°C or if there is a failure in the AC grid for more than 5 seconds, the PEFS Firefighter safety switch will automatically disconnect the DC current between the PV system and the inverter.
This creates a safer environment for the firefighters and reduces potential damage to the PV system.
If the switch disconnects due to AC grid failure, it will automatically switch back on when the AC is back. The client doesn’t need to reset it manually each time.
