Fire Safety



The Tigo TS4-A-2F is a reliable, cost effective rapid shutdown solution that meets the latest module level shutdown requirements, including NEC 2017/2020. It is UL PVRSS certified for connectivity with the largest network of inverters, many of which have a built in RSS transmitter. By connecting to two modules, the TS4-A-2F reduces labor time and enables 16% fewer connections on a 14 panel string compared to single channel MLPE.
