## Summary description

TIGO TS4-X-O is a module-level power optimizer for photovoltaic systems rated 25A and 800W. Supplied with a 0.12/1.2 m cable and MC4 connector, it improves panel-level performance and monitoring. Suitable for retrofit or new PV installations to enhance energy harvest, safety and module-level shutdown functions.

## Long description

TIGO TS4-X-O module optimizer is a device designed for module-level power optimization in photovoltaic (PV) systems. Rated for 25 A and up to 800 W, the optimizer is supplied with a 0.12/1.2 m cable and MC4 connector for simple connection to standard PV modules. The TS4-X-O enables improved energy harvest, module-level monitoring and rapid shutdown capability suitable for both retrofit and new installations.
Advantages
The TS4-X-O improves string performance by optimizing output at the module level and reducing mismatches caused by shading, soiling or module mismatch. Built for reliability, it supports module-level monitoring and integrates with TIGO monitoring platforms. Compact dimensions and included MC4 cabling simplify installation and reduce the need for additional wiring components.
Suitable for
Residential and commercial rooftop PV arrays where module-level optimization is required
Retrofitting existing solar installations to improve energy yield and add monitoring
New PV installations that require module-level rapid shutdown and monitoring
Systems with partial shading or mixed module orientations to mitigate mismatch losses
Когда он может быть неуместен
The TS4-X-O is intended for use with individual PV modules and requires compatibility with the inverter and monitoring system. It may not be necessary for small single-module systems where module-level optimization provides marginal benefit. Systems that already include integrated module-level power electronics or string inverters with equivalent features may not gain significant additional value from adding this optimizer.
Key specifications
Maximum current: 25 A
Maximum power rating: 800 W
Connector type: MC4-compatible connection
Included cable: 0.12/1.2 m cable (pre-attached)
Gross weight: 0.62 kg; net weight: 0.52 kg
Dimensions (packaging gross): 138 mm × 140 mm × 23 mm
Warranty: 300 months
How to use
Install the TS4-X-O on the junction of the PV module as specified by the module and optimizer manufacturer. Connect the optimizer to the module using the supplied cable and MC4 connector, and integrate the communication/monitoring link according to system design. Follow inverter and TIGO installation manuals for placement, polarity verification and commissioning steps. After installation, use the TIGO monitoring platform to verify module-level outputs and to enable safety functions such as rapid shutdown if required by local regulations.
What to consider before purchase
Ensure compatibility with module electrical characteristics (current and power ratings) and with the inverter/monitoring system
Confirm that the included cable length and MC4 connector type fit the planned module layout and roof run lengths
Check warranty coverage and local support options for long-term service
Consider whether module-level optimization is cost-effective for your system size and shading conditions
Usage recommendations
For best results, use the TS4-X-O across modules that experience mismatch or partial shading, pair with the TIGO monitoring gateway for full visibility of module performance, and follow the manufacturer's commissioning procedures to enable safety and optimization features.
