About Rapid Shutdown

3.1 Intended Use of the Rapid Shutdown
The Rapid Shutdown has been specially developed as a safety device for direct current (DC) photovoltaic installations. The DC disconnect switch is used to disconnect the connection strings of the installation in case of an emergency situation. Such an emergency situation could be in case of fire.

3.2 Location of the Rapid Shutdown
The Rapid Shutdown needs to be placed as close to the solar panels as possible. Due to its enclosure, the switch is protected against external influences like dust and moisture.  The whole set-up is conforms to IP66 which makes it suitable for outdoor usage when needed.

Shutdown Mode

Automatic Shutdown

Automatically shut down the DC power of panels when detecting the temperature of the area is higher than 70℃.

AC Power Shutdown

Firefighters or homeowners can manually turn off the AC power of the distribution box when in an emergency or it can automatically shut down when the AC power has lost.

Manual Shutdown

In an emergency, it can be shut down manually through the Panel Level Rapid Shutdown Controller Box.
