SMA SunSpec JMS-F Rapid Shutdown Module

The SunSpec Rapid Shutdown System (model JMS-F), available from SMA, is one of the most cost-effective and reliable solutions for fulfilling NEC 2023/2020/2017 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.

Features

• Cost-Effective - Simple plug and play installation
