SMA SunSpec Rapid Shutdown Device
For users of SMA solar products, the SMA JMS-F SunSpec is an ideal solution for your system’s rapid shutdown needs. All solar power systems are required by the National Electrical Code (NEC) to have rapid shutdown capabilities, meaning that your system needs to disconnect and de-energize at the panel level quickly and reliably. To do this, you need a rapid shutdown device attached to each panel that’s compatible with your inverter. If you have an SMA inverter, the SMA JMS-F SunSpec is the perfect choice.
One of the key features of the SMA JMS-F SunSpec is its use of power line communication (PLC) to transmit the SunSpec signal over existing DC lines. This setup eliminates the need for extra communication cables, simplifying installation and reducing labor time and costs. The device also comes equipped with a 1.2-meter cable and MC4 connectors, allowing for straightforward plug-and-play installation in your solar power system—whether it’s a new system or you’re retrofitting an existing system.
In terms of performance, the SMA JMS-F SunSpec Rapid Shutdown Device boasts as much as 50% fewer internal components when compared to other rapid shutdown devices, enhancing reliability and improving longevity. It supports a maximum open-circuit voltage of 60V, a maximum continuous input current of 15A, and is compatible with system voltages up to 1500V. This rapid shutdown device is designed to operate in temperatures ranging from -40 degrees Fahrenheit to 113 degrees Fahrenheit and has an enclosure rating of IP68, making it suitable for various environmental conditions.
Safety is paramount in solar power systems, and the SMA JMS-F SunSpec meets the highest safety standards by automatically shutting down solar panels when the SunSpec signal is interrupted. This rapid de-energization protects first responders and maintenance personnel during emergencies. The device is certified under UL 1741 and complies with NEC requirements for rapid shutdown, ensuring adherence to safety standards.
The SMA JMS-F SunSpec is fully compatible with SMA inverters, ensuring seamless integration into residential and commercial PV systems alike. Its simplified design with fewer components minimizes potential points of failure, contributing to a longer service life and reduced maintenance needs.
