[Rocklin, CA] SMA America recently announced its NEC 2014 Section 690.12–compliant Rapid Shutdown System. The company engineered the system for compatibility with Sunny Boy TL-US and 5.0-US/6.0-US inverters that have multiple MPP tracking channels, and the system is also compatible with SMA’s Secure Power Supply. Prewired MC4 connectors reduce materials and installation time. The SMA rapid-shutdown solution includes two main components.The Rapid Shut Down Box has a maximum input voltage of 600 Vdc and accommodates four PV source circuits (two in parallel per channel). The array powers the integrated power supply (maximum draw 5 W). SMA’s Rapid Shutdown System performs an automatic self-test upon startup. The Rapid Shutdown Controller allows manual triggering of the system’s rapid-shutdown function.
