PROJOY PEFS-EL50H-6 fire protection switch - P2 (MC4) - 3 string
PROJOY PEFS-EL50H-6 fire protection switch - P2 (MC4) - 3 string
Projoy's PEFS series DC safety switch for firefighters in the event of a fire on a building with a photovoltaic installation, after manually turning off the AC power on the inverter side, it will automatically turn off and isolate the photovoltaic panels from the rest of the installation, effectively eliminating high DC voltage from the PV installation. This allows firefighters to take action to extinguish a fire or eliminate another hazard without risking electrocution.
The same is true for maintenance work carried out by the power company. After an AC power outage, the PEFS circuit breaker will automatically disconnect the DC circuit of the photovoltaic system, causing the voltage on the AC side of the inverter to be cut off, thus affecting the life of the inverter. The Projoy safety switch will also come in handy during repair or maintenance work carried out on the customer's photovoltaic installation.
Projoy PEFS-EL50H-6(P2) model allows disconnection of up to 3 chains of PV panels.
