Tigo Energy, Inc. has launched the Tigo TS4-A-F and TS4-A-2F rapid shutdown devices, which are now available in the global market. These products provide fire safety protection for two PV modules up to 500 Watts (Tigo TS4-A-2F) and for solar modules up to 700 Watts (Tigo TS4-A-F). These devices help system owners, firemen and first responders operate securely without being exposed to high voltage DC power from solar components due to their quick shutdown capability. The TS4-A-F provides rapid shutdown functionality in a one-module-to-one-TS4 configuration. Meanwhile, the TS4-A-2F connects to two modules, thereby reducing labour time, and reportedly enables 16 per cent fewer connections on a 14-panel string as compared to a single channel system. Certified by the International Electrotechnical Commission and UL, both of these rapid shutdown systems (RSS) are compatible with hundreds of inverters and compliant with various NEC rapid shutdown requirements. Further, inverters that have integrated RSS transmitters can communicate with the TS4-A-F and TS4-A-2F.
