In most PV systems, DC isolation switches are integrated into the PV inverters. But even when the DC switch between the inverter and the PV panels is switched off, there will still be up to 600 ~ 1500 VDC.

In the event of a fire, firefighters can be exposed to very serious potential hazards. But if the firefighters have switched off the AC before extinguishing the fire, the PEFS series safety switch will detect the mains fault and after 5 seconds the PEFS will automatically switch off the isolation switch. As this safety switch is mounted close to the photovoltaic panel, the DC current in the building is disconnected, creating a safe environment for firefighters, reducing potential damage and ensuring the safety of the photovoltaic system.

1. FIND the right time to extinguish the fire


The PEFS series firefighter safety switch follows the international standard firefighter operating procedure. In the event of a fire, once the AC circuit is switched off, the rapid shutdown switch automatically shuts down and isolates the PV panels, so firefighters can eliminate the risk of high voltage to the PV panels on the roof and gain valuable time to deal with an accident.

2. PV PANELS ONLY


The PEFS series uses the PEDS switch and can be used directly with PV panels. In the event of a fire, the fireman's safety switch can quickly shut down the PV system without the risk of high DC voltage. If the customer wants the entire roof to reach an even lower DC voltage (e.g. below 80 V ~ 120 V), multiple fireman's safety switches can be used (one for each 2-3 panels) to ensure maximum safety.

3. RESET AUTOMATICALLY

The PEFS series fireman's safety switch from Projoy resets automatically. When AC power is turned off (e.g. during a power outage) and then power is restored, the PEFS series resets and connects the circuit quickly and automatically. The customer does not have to reset it manually each time.

4. NO ADDITIONAL NETWORK REQUIRED AND MORE STABLE ON-OFF ABILITY


When compared to the other remote-communication-enabled emergency switches on the market, the PEF Projoy Series Fireman's Safety Switch is directly controlled by an AC circuit that does not require an additional network. It simply uses the existing AC power system. In addition, the PEFS does not perform an on/off function via electronic components, but via an arc-fault isolation switch, which disconnects the DC circuit directly with much greater stability.

5. LONGER LIFE CYCLE OF PV INVERTERS

When Projoy's PEFS product is installed in the system, the DC circuit will automatically be switched off in the event of a power failure in the AC circuit, such as during a power outage, power line maintenance or grid failure. This will significantly extend the life of PV inverters and make it safer to repair or replace PV inverters.

6.USE POPULAR DC SWITCHES

The Projoy PEFS series is equipped with the PEDS switch, which is the world's most popular DC switch for photovoltaic applications. The response time of Projoy's resilient recoil mechanism is just 5 milliseconds, which can quickly extinguish the arc. Combined with self-cleaning contacts, the switches have increased durability and safety. For this reason, PEDS has been selected by many PV inverter manufacturers as the preferred DC switch.

7. AS A PROFESSIONAL DC SWITCH PRODUCER


Projoy has extensive experience in DC switch design and has customers worldwide. Projoy has become the first company in China to develop physical insulation with DC arc extinguishing capability without the use of long-distance communication technology, effectively providing safety for high DC voltage roofs.
