In most photovoltaic systems, the dc isolator is integrated into the dc/ac power inverter. After switching off the dc isolator, the cables between the dc solar modules and dc/ac power inverter running through the building are still subject to up to 1000 v dc. in the event of a fire, firefighters are exposed to a very serious source of potential danger. The ONCCY firefighter safety switch provides the solution. It directly disconnects the dc current in close proximity to the solar modules and creates a safer situation for firefighters.
MANUAL AC POWER SHUT DOWN
The first step for any firefighter in fighting a fire is to shut down the main AC power circuit. This makes it possible to start extinguishing the actual fire without the risk of electrocution. Onccy developed the Firefighter safety Switch according to this standard international safety routine. This prevents firefighters from having to take any extra action in case of a fire, maximizing their and your safety in the event of a fire.
As soon as a firefighter shuts down the main AC circuit, the ERS/ERP will detect this. If this power down situation lasts longer than 5 seconds, the ERS/ERP will automatically switch to the OFF position. Since the ERS/ERP is located close to the PV modules, the high voltage DC current from the PV modules will be completely isolated, which leaves a safe situation for the firefighters when fighting a fire in the commercial or residential building.
Key Features
1. PV module rapid shutdown meeting NEC 2017 & 2020 (690.12) requirements
2. Rapid shutdown: Triggered within 30 seconds after the monitor loses power or the control switch manually turn off.
3. Module level data monitoring: 5 big datum including voltage, current, power generation, power generation operating point, temperature five big data, and in the way of snapshot collection
4. String break protection: active protection, all the PV module safety devices went into shutdown state within 5 secondsBidirectional PLC communication
