SMA Offers Rapid Shutdown System For Residential Solar


SMA has announced its Rapid Shutdown System is now available for immediate shipping to the North American residential solar PV market. Engineered for use with SMA’s Sunny Boy inverter line, the new solution meets 2014 NEC 690.12 requirements and includes the SMA Rapid Shutdown Box and SMA Rapid Shutdown Controller.

“Matching Sunny Boy inverters with the UL-listed Rapid Shutdown System creates a full-package solution, centered around SMA’s best-in-class technology,” says Marko Wittich, SMA executive vice president of sales for the Americas region. “It achieves compliance in areas enforcing or in the process of adopting the 2014 NEC, including Hawaii and Massachusetts.”

The SMA Rapid Shutdown System is designed to pair with the Sunny Boy TL-US and 5.0-US/6.0-US inverters with Secure Power Supply. It operates by the array’s DC power and enables Secure Power Supply functionality during daytime grid outages without interfering with the inverter’s AFCI, ensuring safe system operation at all times, according to the company. With the SMA Rapid Shutdown Box, solar installers are also able to connect multiple strings of modules to independent inverter channels, the company adds.
