The SMA Rapid Shutdown (RSD) System is the most cost-effective way to achieve 2014 NEC 690.12 Rapid Shutdown compliance for systems using Sunny Boy inverters. This DC powered system allows for use of the Secure Power Supply, providing opportunity power to homeowners during daytime grid outages when other rapid shutdown systems would eliminate its functionality. Hybrid switches and automatic self-test ensure system safety and durability, reducing risk and costs. Each component plays a critical role in a PV system; don’t compromise your Sunny Boy’s performance with any other rapid shutdown solution.

The RSC-1X-US-10 rapid shutdown controller is paired with up to 16 SMA Rapid Shutdown Boxes for a code-compliant RSD solution.

About SMA

Key Points:

  • Offers a wide range of inverters to suit most any solar panel or system.
  • Forefront of Inverter technology.

Founded in 1981, SMA Solar Technologies is headquartered in Niestetal, Germany, and has a worldwide presence in 15 different countries including the United States and Canada.

SMA touts themselves as the world's largest producer of solar inverters and monitoring systems for photovoltaic applications. With a wide range of inverters, they have one for every module type and power class including grid-tied, offgrid, or backup applications. Wholesale Solar designs their UL listed Solar Sky Gridtie Systems with SMA SunnyBoy inverters.

While SMA inverters are designed in Germany, the Sunny Central, the Sunny Island, and SMA SunnyBoy inverters in the 3 kW to 7 kW range are assembled in their new plant in Denver, Colorado. These inverters qualify for the ARRA recovery act and are UL and cUL listed.

Continually pushing the envelope when it comes to technology, SMA launched its own SMA solar academy in Rocklin, California, in April 2011. Their Solar Academy is equipped with the latest high-tech teaching tools and demonstration inverters to complement its comprehensive range of courses on photovoltaics and SMA products.
