SMA tigo

SMA and Tigo have announced a new rapid shutdown solution for the commercial market, which will be available in the second half of 2018.

“Since we introduced the Power+ Solution, we have received feedback from installers who are looking for a more cost-optimized way to achieve rapid shutdown in commercial installations,” said Nick Morbach, executive vice president of SMA’s Residential and Commercial Business Unit. “This new offering gives our commercial customers an SMA branded option to comply with the NEC 2017 rapid shutdown requirement, and gives them the specific functionality they need.”

The new rapid shutdown solution will fulfill UL 1741, NEC 2014 and NEC 2017 requirements – particularly the stricter module-level shutdown requirements that will be effective in January 2019. It will be compatible with the power line-based SunSpec Communication Signal for Rapid Shutdown, making it simple and robust. Using the existing DC wires between the inverter and module-level electronics as a communication channel will drastically reduce installation time. Mechanically, it will be compatible with Tigo’s existing TS4 platform.

The product will offer outstanding system safety thanks to full integration with SMA’s world-leading AFCI function. It joins SMA’s portfolio of products that comply with rapid shutdown requirements, including the Power+ Solution and the Rapid Shutdown System.

“We are pleased to work with SMA to develop an option that meets the needs of commercial installers,” said Zvi Alon, CEO of Tigo Energy. “The rapid shutdown solution will be compatible with a variety of modules, and we anticipate that commercial integrators will widely adopt the module-integrated platform.”

Tigo, pioneer of the smart modular Flex MLPE platform, has boosted its portfolio of international inverter partnerships to more than 35 inverter-types that are now Rapid Shutdown certified by Underwriters Laboratories (UL).

SMA was first to adopt Tigo’s portfolio of Rapid Shutdown certified offerings. Additional commercial and residential inverter suppliers that also received the UL certification include:

  • ABB,
  • Fronius,
  • Ginlong Solis,
  • Kaco,
  • Sungrow,
  • Yaskawa – Solectria Solar,
  • and more.

Inverters ranging from 3kW to 30kW are certified with Tigo’s TS4 optimizers with UHD-Core technology and are shipping now. This brings the largest Rapid Shutdown solution offering with the widest adoption to market – providing Installers, EPC, and Owners the most cost-effective response to the NEC 2014 & 2017 code requirements.

“Customers looking for cost effective solutions that comply with strict safety regulations have a solution available. With Tigo’s UL Certification, our partners are exceeding these standards,” said Zvi Alon, CEO of Tigo. “We are excited to add more brands to the most diverse portfolio of approved partners in the industry.”

According to UL’s certification Rapid Shutdown Systems requirements for Distributed Generation Power System Equipment, the rapid shutdown protection is intended to reduce potential hazards and limit exposure to energized PV wiring and equipment to allow emergency first responders to perform work outside the energized area of the PV array. Also, these high reliability PV rapid shutdown systems have a higher system fault tolerance and reliability to perform their intended function under foreseeable single-point component and system failures. Only systems found to comply with these additional functional safety requirements are marked “High Reliability PV Rapid Shutdown System.”

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.

Yaskawa-Solectria Solar inverters now fully compatible with Tigo optimizers

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.

Yaskawa-Solectria Solar extends its string inverter line“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.

System design

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.”
