Simplified rapid shutdown solution for commercial market

14 Nov 2017

SMA and Tigo have announced a new rapid shutdown solution for the commercial market, which will be available in the second half of 2018. The solution will use technology from SMA and Tigo to provide rapid shutdown only, creating a reliable, economical product focusing on key functions to enable NEC compliance. The new rapid shutdown solution will fulfill UL 1741, NEC 2014 and NEC 2017 requirements, particularly the stricter module-level shutdown requirements coming 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 drastically reduce installation time. Mechanically, it will be compatible with Tigo’s existing TS4 platform. The product will offer outstanding system safety thanks to full integration with SMA’s AFCI function.
