Solar Rapid Shutdown Device Panel-Level 2 in 1

The solar rapid shutdown with automatic power off and re-closing functions. When the mains power is off or the emergency stop is started, the module level quick shutdown PLC control box will send a disconnect command to the quick shutdown actuator through the photovoltaic power line to disconnect each photovoltaic panel.

Solar Rapid Shutdown Device Technical Data :

Technical Features:

1.  Rapid Shutdown Functionality: This product incorporates advanced circuitry that allows for the rapid shutdown of solar panels in less than 10 seconds.  This ensures that the system can be quickly deactivated during emergencies, such as fires or electrical faults.

3.  Wireless Communication: The product utilizes wireless communication technology to transmit control signals, eliminating the need for additional wiring and reducing installation complexity.  It provides reliable and secure communication between the rapid shutdown device and the control center, ensuring efficient operation.

4.  Scalability: Our solar rapid shutdown solution is highly scalable, making it suitable for residential, commercial, and utility-scale solar installations.  It can accommodate various system sizes and configurations, providing flexibility for different project requirements. 

Solar Rapid Shutdown Key Functions:

1. Emergency shutdown: In the event of fire or the danger of solar panel failure, the fast shutdown device can quickly shut off the DC voltage of the solar end, and the voltage will be 80V in 30 seconds.
2. Routine maintenance: During routine maintenance, the quick shutdown function can reduce the voltage to 80V before maintenance, reducing the waiting time for voltage drop and improving O&M efficiency.
3. Compliance with safety standards: BLD quick shut-off meets the requirements of NEC regulations in the United States, which can ensure the safety of users' property and the safety of operation and maintenance and fire personnel.

Solar Rapid Shutdown Product Applications:

1. Residential Solar: BLD rapid shutdown solutions are solar installations designed to protect the lives and property of residential personnel. Keep emergency responders and maintenance personnel safe by quickly shutting down the solar system in an emergency.
2. Commercial buildings: While installing the fast shut-off device, the maintenance personnel of commercial buildings can perform regular maintenance for commercial solar energy more safely, and can quickly reduce the voltage and rescue it quickly in the event of an accident.
3. Public utilities and large-scale solar power plants: When some plates of large power plants are in danger, the corresponding voltage of the quick shut-off device can be turned off to ensure the safety of operation and maintenance personnel.
