JMS-F SUNSPEC RAPID SHUTDOWN DEVICE
The easy module level rapid shutdown solution
The SunSpec Rapid Shutdown System (model JMS-F), available from SMA, is the most cost-effective and reliable solution
for fulfilling NEC 2017 module level shutdown requirements. The module-level device is certified for compatibility with the
SunSpec communication signal and SMA inverters, making compliance simple and easy. By using the existing DC lines
between the inverter and PV array for power line communications, installation and labor are significantly reduced. No
additional wires or communication equipment is needed. The solution also features up to 50% fewer internal components
vs alternatives, resulting in greater lifetime reliability.
