Tigo has launched 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 a particular 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 cost-efficiency. The Duo also supports Tigo's 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). Tigo's Duo provides PV systems with faster installation, integrated monitoring, 99.6% efficiency, compatibility with 60-cell modules, and module-level voltage shutdown.
