Installation Manual for PV Link and SnapRS 7
PWRcell Inverter control panel. The PV Link
meets the ground fault protection require -
ments in NEC Article 690.41(B).
AFCI Information
The PV Link is a Photovoltaic DC Arc Fault
Circuit Protection Type 1 device that incorpo -
rates an internal arc fault circuit interrupter
(AFCI) and meets the arc fault circuit protec -
tion requirement in NEC Article 690.11.
PVRSS Information
PV rapid shutdown system (PVRSS) require -
ments have evolved over time and are defined
by the National Electrical Code (NEC) in con -
junction with UL 1741. Determine what level of
rapid PV shutdown is required for your juris -
diction.
• The 2011 NEC and older editions do not
require PVRSS capability.
• The 2014 NEC requires rapid shutdown
only on the conductors leaving the PV
array.
• The 2017 and 2020 NEC require rapid
shutdown at the PV module level and on
the conductors leaving array.
PV Link is a PV rapid shutdown system equip -
ment (PVRSE) component within a PVRSS. It
provides rapid shutdown for the conductors
leaving the array. SnapRS devices are
required for PV module level rapid shutdown
withing the array. See
PVRSS Compliance
Guidelines
for more information.
