Inverter Compatibility
There are two places to look for Tigo/inverter compatibility information:
Inverter Compliance Letters
These are letters of understanding between Tigo and inverter vendors. T...

The TS4-A-X (TS4-A-F, TS4-A-M, TS4-A-S, TS4-A-O) is Tigo's latest add-on MLPE (Module Level Power Electronics). It features some improvements over the TS4-R, but keeps the same great reliability a...

How does Optimization Work?
Predictive IV
Predictive IV uses module behavior statistics in conjunction with Impedance Matching in order to predict the optimum settings for a module to generate...

The TS4-A-X (TS4-A-F, TS4-A-O, etc) has removable module clips. Under the clips are two mounting holes that can be used with any fastener (screw, bolt, etc) for mounting the TS4-A-X to racking or ...

Yes! See below for details. Many of our competitors do not allow this.
Connector Compatibility
Tigo recommends that PV connectors should always be matched from the same manufacturer. In other wo...

Metal parts are the only ones that often need to be grounded, and the only metal part not enclosed inside the TS4 device is the the TS4-A/TS4-R mounting bracket. The device inside the plastic enclo...

The TS4 solution is modular, meaning each module can be outfitted with a TS4 cover to fit the application. On a single string, you can mix and match certain combinations of TS4s. Tigo refers to the...

The TS4 solution functions on the module level, so the data received will be data from only the specific modules with the TS4-M covers. You may extrapolate string current from a single module, as t...

No. The output voltage limit is above Vmp, and does not reduce the power output of the module.
It enables more modules per string by limiting the open circuit voltage (Voc) and eliminates the cold...

The Flex TS4-R and TS4-A are generations of the same series. They both are add-on (retrofit) MLPE units that can be installed on a standard PV module, and can add functionality to almost any system...

Yes. Modules with TS4-R or TS4-A add-on units are compatible with other Tigo products and can share the same Cloud Connect and Gateway. The same design guidelines for TS4 integrated modules apply t...

The TS4 monitoring (either TS4-M or TS4-R-M/TS4-A-M) is a passive unit to allow most accurate measurement of the PV module it's installed on. As result, if the unit's input requirements aren't met,...
