SMA Rapid Shutdown System


The SMA Rapid Shutdown 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 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.
