Yaskawa – Solectria Solar announced full compatibility of its three-phase string inverters with Tigo’s module optimizers, fully complying with the 2014 and 2017 National Electric Code (NEC) 690.12 Rapid Shutdown Requirements.
“We are pleased to offer our customers a solution that complies with the upcoming module-level rapid shutdown requirements,” said Miles Russell, Director of Product Management at Yaskawa – Solectria Solar. “Tigo’s integration with Yaskawa – Solectria Solar inverters allow us to stay at the forefront of the latest technology and code changes, while keeping costs low. This solution gives customers the reassurance they are looking for when it comes to safety.”
Tigo’s UL and IEC-certified optimizers TS4-L and TS4-O discharge the capacitors in the inverter to ensure zero voltage at shutdown. In addition, the built-in automatic over-current and over-temperature features reduce liability and provide safer conditions for installers, customers and first responders in case of emergency.

Tigo conducted extensive testing to validate the effective performance of the systems together in standard operating environments. Yaskawa – Solectria Solar’s three-phase string inverters, PVI 23/28/36TL, can be used successfully in combination with the following TS4 product families from Tigo:
• TS4-B models –D, -M, –S, -O, -L
• TS4-R models –M, -S , -O
“Tigo is distinguished in the industry as being the sole company to offer a certified modular platform so customers can cater their system needs by simply replacing the TS4 functional covers,” says Gal Bauer, Director of Training and Development at Tigo. “By combining our innovative technologies with tier 1 companies like Yaskawa – Solectria Solar, Tigo is providing the solar market with the safest solar energy generation products and management systems.”
