In a solar power system, rapid shutdown functionality is a requirement set forth by the National Electrical Code. This functionality means that your system is capable of shutting down and de-energizing at the module level almost instantaneously. This protects maintenance personnel performing routine maintenance, as well as first responders who may need to access the roof of your home in an emergency situation.
Several rapid shutdown devices are needed to make this functionality possible, and the AP Systems Rapid Shutoff Device is one. This device maintains constant communication with the transmitter in your solar power system, monitoring both voltage and current. If the transmitter signal is absent (something that occurs when the system shuts down or malfunctions), the AP Systems Rapid Shutoff Device initiates the rapid shutdown sequence, disconnecting the panel from the system to prevent electrical hazards.
The AP Systems Rapid Shutoff Device connects directly to your solar panels, so one is needed for each panel in your solar power system. This device operates with a low minimum voltage of 8V, reducing energy consumption for each device installed. They’re designed to work seamlessly with a wide range of solar panels and inverters, including popular options like SMA inverters and other SunSpec-certified devices.
Compact and lightweight, the AP Systems Rapid Shutoff Device is easy to install, and can even be mounted directly on your panels’ racking system. But don’t let the small package fool you; this device is incredibly durable as well. The AP Systems Rapid Shutoff Device’s electronic components are housed in an IP68-rated enclosure, ensuring that they’re protected against harsh environmental conditions. This means you don’t need to worry about windblown dust and heavy rain damaging your rapid shutdown equipment.
The AP Systems Rapid Shutoff Device meets NEC rapid shutdown requirements and is SunSpec certified, ensuring that it adheres to the highest industry safety standards. Powered by an Application-Specific Integrated Circuit (ASIC) and integrated Texas Instruments chips, you can feel confident that you’re getting only the latest and greatest in rapid shutdown technology. This level of performance ensures consistency and reliability from your shutdown devices, all with fewer electrical components than other such devices on the market.
