Tigo Delivers Industry’s First UL-Certified PV

Tigo Delivers Industry’s First UL-Certified PV Module Solution
Meeting 2017 & 2014 NEC Rapid Shutdown Regulations


Tigo’s TS4 MLPE modular platform has been certified by Underwriters Laboratories (UL) and International Electrotechnical Commission (IEC) for fully complying with National Electric Code (NEC) 2014 and 2017 690.12 Rapid Shutdown regulations. Tigo is the only UL-certified MLPE solution with multiple inverters from various inverter manufacturers.




We are proud to announce that our inverter partners are enabled to use UL- and IEC- certified Tigo optimizers with module-level deactivation:



We are now shipping our UL-certified offering worldwide, including the TS4 Safety (TS4-S), Optimization (TS4-O), and Long Strings (TS4-L) functional covers.  The UL and IEC certifications apply for 600V, 1000V, and 1500V PV system designs using any type of module with Tigo’s TS4 MLPE modular platform. Newly released TS4-L and TS4-O also uniquely discharge capacitors in the inverter that ensure zero voltage at any given time. In addition, the built-in automatic over current and over temperature protection reduces liability and is safer for installers, customers, and first responders in case of emergency.
