Tigo Energy received UL PVRSS (Photovoltaic Rapid Shutdown System) certifications for approximately 30 inverter models, bringing its certified inverter total to more than 200 inverters from 17 different companies. Tigo already had the largest network of certified inverters for customers to choose from and this adds even more options to the rapidly growing list.
“This is by far the biggest variety of certified inverters that are available for use with rapid shutdown devices anywhere,” said Sarah Ozga, Product Manager for Tigo. “Our customers want the freedom to choose the inverter and capacity that they want, and we are delivering it for them.”
The certified inverters range from 2.5 kW, single phase for small residential installations to 100 kW, three-phase for large commercial arrays. It also includes newly introduced residential hybrid inverters, which are designed for easy integration with energy storage systems.
In order to receive certification, every inverter family was independently tested with Tigo’s TS4 family of rapid shutdown devices accordingly to UL standards. UL’s rapid shutdown testing is the most rigid testing standard available, proving functionality, reliability and safety of rapid shutdown systems rather than basic function.
“We have certified our rapid shutdown solutions with essentially every major string inverter manufacturer,” added Ozga. “This is an amazing accomplishment and I’m very proud of our team.”
The certified inverters include the following brands:
• Canadian Solar
• Chint Power Systems
• Delta Electronics
• Ginlong Solis
• Growatt New Energy
• Hanwha Q-Cells
• Huawei Technologies
• LG Electronics
• Schneider Electric
• SolaX Power
• Yaskawa Solectria Solar
The UL PVRSS certification fulfills a necessary safety requirement for PV Rapid Shutdown in the US National Electrical Code, whereby both the inverter and the rapid shutdown device must be tested as a “system”. Rapid shutdown devices are now required with rooftop PV installations across the vast majority of the United States. Similar requirements are being adopted and discussed throughout the world.
