The Tigo TS4-A-O is a full power optimizer that adds per-panel MPPT, rapid shutdown, and panel-level monitoring to any string inverter system. Unlike the TS4-A-S (which only handles shutdown and monitoring), the TS4-A-O actively optimizes each panel's output — making it a cost-effective alternative to full microinverters for shaded string inverter installations.
