TS4-F

SMA and Tigo have announced support of a new SunSpec compatible module-level rapid shutdown unit, the TS4-F (Fire Safety). The solution joins the current TS4 platform with a focus on emergency responder safety. It uses proven MLPE technology from SMA and Tigo to provide rapid shutdown only, creating a reliable, economical product that focuses on key functions to enable NEC compliance.

The solution offers two options. The TS4-F is integrated into a smart module. The TS4-R-F retrofits a regular standard module with a module-level rapid shutdown device and is available through SMA.

The new rapid shutdown solution is a cost-effective way to fulfill UL 1741, NEC 2014, and NEC 2017 requirements – especially the stricter requirements for inside the array boundary that will be effective in January 2019. It will be compatible with the power line-based SunSpec Communication Signal for Rapid Shutdown, making it simple and robust. Using the existing DC wires between the inverter and module-level electronics as a communication channel will significantly reduce installation time.

The TS4-F and TS4-R-F products will offer outstanding system safety thanks to full integration with SMA’s world-leading arc fault detection (AFCI). They join SMA’s portfolio of products that comply with rapid shutdown requirements, including the Power+ Solution and the Rapid Shutdown System.

SMA is planning for its U.S. string inverter portfolio to be fully SunSpec Rapid Shutdown compliant in time for customers to meet the module-level rapid shutdown requirements of NEC 2017, which will become mandatory in most states by January 1, 2019.
