Product Description

Firefighter safety switch ensures the safety for Photovoltaic system

ERS series firefighter safety switch is applied to residential PV system or industrial and commercial PV system, its maximum loop voltage can be up to 1500V which meets the requirements of high-power panel.

 

  • Seize the valuable time to put out fire

ERS series firefighter safety switch matches international standard firefighter working procedure. When a fire occurs in the photovoltaic system, the AC side will be disconnected firstly.

On the other hand, relying on advanced temperature sensor to real-time monitoring the temperature inside the enclosure, ONCCY's firefighter safety switch can automatically disconnect the switch if the inside temperature exceeds 70ºC.

  • Isolate PV panels completely

The ERS series ERS DC Isolator and can be used directly with PV panels. In case of fire, the firefighter safety switch can rapidly shut down the PV array, without any risk of high DC voltage. If the client wants the entire roof to achieve an even lower DC voltage (e.g. under 80V ~ 120V), it is possible to apply multiple safety switches (one for each 2-3 panels) to ensure maximum safety.

  • Reautomatically

ERS series firefighter safety switch resets automatically. When the AC power supply is turned off (e.g. during a power cut) and then the supply is restored, the ERS series will reand connect the circuit quickly and automatically. The client doesn't need to reit manually each time.

  • Prolong the life cycle of solar inverter

When ERS product is installed in the system, in case the AC circuit has no power such as during a power cut, powerline maintenance or grid failure, the DC circuit will be automatically shut down. This will greatly prolong the life of the solar inverters, and makes it safer to repair or replace solar inverters.

  • the most popular DC switches

ERS series are equipped with DC isolator, which is the most popular PV application DC isolator worldwide. Combined with self-cleaning contacts, the switches have increased durability and safety. For this reason, the ERS has been many PV inverter manufacturers.

  • Professional DC Isolator manufacturer

ONCCY has rich experience in developing DC switches and has customers worldwide. ONCCY has become the No. 1 company in China developing physical isolation with arc extinguishing capability for direct current without using remote communication technology, effectively ensuring the safety of high DC voltage roofs.

  • 2-year long life design for photovoltaic system

ERS series products industry level capacitors and motors, and strictly control the internal key components. It can work normally in harsh environments from minus 20°C to 70°C. It is equipped with a waterproof breathable valve to effectively avoid cavity condensation. The designed life span can meet the operation requirements of the photovoltaic system which is  2 years.
