Tigo, pioneer of the smart modular Flex MLPE platform, announced the launch of three new "Duo" covers to its TS4 add-on / retrofit solution: TS4-R-O-Duo (Optimization), TS4-R-S-Duo (Safety), and TS4-R-M-Duo (Monitoring). The TS4-R-X-Duo brings smart module functionality to standard PV modules, adds smart features to new PV installations, and upgrades underperforming PV assets. With UHD-Core technology and expanded specifications, the Duo supports two PV modules connected in series with a combined power of up to 700W and a combined voltage of up to 90V.

With a universal base and a range of covers containing flexible module-level power electronics (Flex MLPE), Tigo's Duo increases freedom of choice when selecting features for any project and budget. All three Duo covers work with any inverter and any module within its electrical specifications. This new addition is fully compatible with Tigo's current shipping products. Customers can design Smart PV Systems by mixing any of the TS4 products for the highest cost-efficiency. The Duo also supports Tigo's unique Selective Deployment capabilities. Both the TS4-R-O-Duo (Optimization) and TS4-R-S-Duo (Safety) are NEC 690.12 rapid shutdown compliant and pending approval by Underwriters Laboratories (UL).

"Around the world, we have received requests for an add-on product that is optimized, safe, and monitored for commercial-sized products," says Zvi Alon, CEO at Tigo. "Now, we are meeting those demands with the most flexible MLPE which is also widely recognized in the market for the highest ROI."
