Add-on Optimizer for 1 PV Module
Rapid shutdown device to work with SunSpec capable inverters.
JMS-F SUNSPEC RAPID SHUTDOWN DEVICE
The SunSpec Certified 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.
