Tigo TS4-A-O 700W power optimizer TS4-A-O_700

The Tigo TS4-AO optimizes each PV module to which it is connected, improving the performance of the PV string in the event of shading or module mismatch. In addition, it improves energy efficiency by upgrading poorly performing photovoltaic systems or adding smart features to new installations. The TS4-AO with UHD-Core technology and extended specifications supports PV modules up to 700W.


The TS4-AO has a security feature that only works when the optimizer is connected to Cloud Connect or Cloud Connect Advanced. The function is activated automatically or manually - after activation, the voltage and current of each module drops to 0.

Manual control of the safety function can be accomplished by connecting a fire switch to Cloud Connect or Cloud Connect
