1.  Rapid Shutdown Functionality: It features intelligent circuitry that quickly shuts down the solar panels in less than 10 seconds. This ensures a quick shutdown of the system in the event of an emergency such as a fire or electrical failure.

2.  Compliance with NEC Requirements: Our solar quick shutdown solution meets the National Electrical Code (NEC) requirements for quick shutdown. It ensures safe operation of your solar system and prevents electrical hazards to first responders and maintenance personnel.

3.  Wireless Communication: The product utilizes wireless communication technology to transmit control signals without the need for additional wiring, reducing installation complexity. It provides reliable and secure communication between quick shutdown devices and the control center to ensure efficient operation.

4.  Scalability: Our Solar Quick Shutoff is highly scalable for residential, commercial and utility-scale solar installations. It can accommodate a variety of system sizes and configurations, providing flexibility for different project needs.




Solar Panel Rapid Shutdown Module-Level 2/1 In 1 Function:

1. Emergency shutdown: When there is a risk of fire or solar panel failure, the rapid shutdown device can quickly cut off the DC voltage at the solar end and restore the voltage to 80V within 30 seconds.

2. Routine maintenance: During routine maintenance, the Solar Rapid Shutdown feature reduces the voltage to 80V in a short period of time prior to maintenance, reducing the waiting time for the voltage to drop and improving operation and maintenance efficiency.

3. Compliance with safety standards: The BLD rapid shutdown with NEC regulations to ensure the safety of the user's property, as well as the safety of operations and maintenance personnel and firefighters.

Solar Panel Rapid Shutdown Module-Level 2/1 In 1 Product Applications:

1. Residential Solar: BLD Rapid Shutdown is a solar device designed to protect the lives of residents and the safety of their property. Rapid shutdown of solar systems in emergency situations ensures the safety of emergency responders and maintenance personnel.

2. Commercial buildings: When installing a rapid shutdown device, maintenance personnel in commercial buildings can safely perform regular maintenance on commercial solar energy in a short period of time and reduce the risk of secondary injuries by quickly lowering the pressure and rescuing quickly when an accidental risk situation occurs.

3. Public utilities and large-scale solar power plants: When the solar panels of a large power plant are in danger, the corresponding voltage of the rapid shutdown can be cut off to ensure the safety of operation and maintenance personnel.
