Tigo TS4-A-S Module-Level Power Electronics
The Tigo TS4-A-S is a module-level power electronics (MLPE) device that adds rapid shutdown capability and panel-level monitoring to any existing solar panel on any string inverter brand. Unlike full microinverters, the TS4-A-S works with the string inverter already installed — making it an ideal solution for code compliance upgrades or new systems where the client wants panel-level visibility without full microinverter cost.
