The Rapid Shutdown Box (PN: RSB-2S-US-10) is what actually disconnects the solar panels from the electrical system and the Rapid Shutdown Controller (PN: RSC-1X-US-10) is the button switch that activates the box. The RSB self-tests upon startup to ensure it's working properly, which means you never have to worry about malfunctions if an emergency arises. It does not interfere with AFCI.

Rapid Shutdown Showcase: A review of commercial solar RSD strategies and solutions. PVRSE vs. PVRSS. Compliant RSD will have either a Photovoltaic Rapid Shutdown Equipment (PVRSE) or a Photovoltaic Rapid Shutdown System (PVRSS) listing under UL 1741 and labeled appropriately. PVRSE listings consider the RSD components independently of other.

Rapid shutdown devices are designed to lower the voltage in the DC system conductors to 30 volts within 10 seconds after the inverter is disconnected, he said. For standard string inverter systems, the NEC requirements also call for a rapid shutdown device for every section of the conduit run that is more than one foot from the array, he said.

In those examples system safety coupled with the ability to prevent disruption to the daily business operations were key drivers as to why these companies voluntarily adopted rapid shutdown. A simple fault within the DC wiring of the array could result in disruption of business and significant business losses simply because the array’s DC energy could not be switched off.

SolarBOS Rapid Shutdown Solutions, as part of the String Inverter Solutions, provide a low-cost and space-saving solution for residential and commercial solar systems, when it isn't feasible for the string inverter to be within the array boundary (per NEC 690.12). All products are ETL listed to UL-1741 for 1000 VDC photovoltaic systems and use compact NEMA-4X polycarbonate enclosures. They can.

Photovoltaic Rapid Shutdown System Equipment. The word “Photovoltaic” is permitted to be abbreviated “PV.” UL also Certifies (Lists) entire rapid PV shutdown systems under Photovoltaic Rapid Shutdown Systems (QIJS). These rapid shutdown systems are intended to be installed as part of the PV array system. Systems certified under this category have been evaluated at the systems level for.

NEC 690.12 Rapid Shutdown Primer Introduction The 2014 edition of the National Electrical Code1 (NEC) was the first to introduce a mandatory requirement called Rapid Shutdown, intended as an aid to firefighters by reducing the risk of shock hazard when fighting fires. This new requirement applies to PV systems on buildings in the US and is contained in Section 690.12 of the 2014 and later.
