PV system with voltage up to 600 ~ 1500V. Therefore, once a fire occurs, users and firefighters will face great dangers. Switch SOLAR ELECTRICITY fire protection can provide a safe fire fighting environment for firefighters and reduce fire loss for users to ensure the safety of PV power stations.
System SOLAR ELECTRICITY fire protection include:
1. Control Panel Level Control Panel PEFS-PL Fire Safety Switch / Quick Off (PLC, 1-1).
Level Control Panel The PEFS-PL Fire Safety Switch is a reliable quick-off switch in accordance with NEC regulations 2017/2020 690.12 on fire safety for rooftop PV systems.
Features: One quick shutdown connected to 1 PV module, using high quality materials that are temperature resistant, corrosion resistant and impact resistant. Simple and convenient design and installation, saving labor costs.
2. Integrated DC isolating circuit breaker for inverter – Solar power fire protection equipment
The PEDS-EL 16-32A DC Isolation Switch has a high-speed “on – off” switching mechanism. The device uses an energy-storage spring, which switches quickly. The maximum switching time is less than 5ms. Contacts self-cleaning design, reduce resistance and energy consumption of DC switch. This helps to prolong the life of the switch. Magnetic arc quenching and gate arcing are used to effectively suppress arcs.
3. External AC isolating breaker:
PEMC series DC die shell circuit breakers (500V, 250A, 2P). Has short circuit protection and overload protection function that can work under load, with outstanding performance. Rated working voltage up to 1500V; No flying arc (no need for external arc extinguishing cap).
4. AC isolating circuit breaker integrated in the distribution box:
PEJB-1-1 DC Junction Box: Suitable for household photovoltaic power generation systems. Suitable for 1 string 1 string input PV system. Protection level IP65
