General Information
PVRSS Information
PVRSS requirements have evolved over time and are
defined by the National Electrical Code (NEC) in
conjunction with UL 1741. The 2017 and 2020 NEC
added to the PVRSS requirement by mandating the need
to reduce voltages of controlled conductors to less than
80 VDC within the array. NEC Article 690.12(C) contains
all of the requirements for the type and location of the
PVRSS initiation device. SnapRS is a PV rapid shutdown
system equipment (PVRSE) component within a PVRSS.
