Tigo adds two more solar optimizers to UHD-Core lineup

Tigo logo

Tigo’s adding a few more options to its UHD-Core optimizers lineup announced last March. Joining the TS4-L (Long Strings) and TS4-O (Optimization) will be TS4-M (Monitoring) and TS4-S (Safety). The UHD-Core TS4-M is a cost-efficient MLPE monitoring device that produces a high sampling rate. The TS4-S adds to TS4-M’s functionality by providing module-level deactivation capabilities. The company says this release completes its TS4 platform featuring an enhanced design architecture and component rating.

TS4 optimizers explained

Tigo TS4 optimizers with UHD-Core technology support more module types than any other optimizer on the market for three reasons. First, the maximum input voltage at standard testing conditions has improved to 90V which allows for compatibility of modules with up to 96 cells. Second, the maximum input current has increased to 12A which enables the use of the highest efficiency and bifacial modules on the market. Third, the power capacity has upgraded to 475W to support the world’s most powerful modules. These enhanced electrical characteristics of the UHD-Core technology result in higher energy harvest for any module up to 475W.

“The demand for our innovative UHD-Core technology in the TS4-L and TS4-O optimizers was so impressive that we have expanded the offering to include TS4-M and TS4-S,” said Zvi Alon, CEO of Tigo. “Our commercial and utility customers will be pleased with lower O&M costs, safer solutions, and expanded inventory. Now that our TS4 platform has the highest accuracy in remote module-level monitoring, we plan to bring more superior communication solutions to the market in the near future.”

This TS4 UHD-Core platform is fully monitored through Tigo’s Cloud Connect Advanced (CCA) data loggers with remotely upgradeable firmware. The high definition sampling rate technology also allows the highest accuracy remote monitoring of voltage and current available in the market – including remote access to individual module information (i.e. panel type, barcode, manufacturing origin, location, and production date). All Tigo TS4 platform products are autonomous and feature selective deployment. They can be fitted to new or existing installations on any string or sub-string size, driving the optimization cost as low as 2 cents per watt. They are compatible with most of Tigo’s inverter partners and any module type including monocrystalline, polycrystalline, thin-film, and bifacial.
