ONCCY developed and launched the ERS series rapid shut down switch(RS switch). After installing the Onccy switch, firefighters can remotely turn off the AC power before extinguishing the fire. The quick-shutoff switch will automatically disconnect the internal DC isolation switch after collecting the signal from the power grid.
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.
