GFDI Information
The PV Link's internal ground fault detector and interrupt-
er (GFDI) is designed to trip at 240 mA (± 40 mA) of PV
DC voltage ground current. Ground faults are displayed
on the PWRcell Inverter control Panel. The PV Link
meets the ground fault protection requirements in NEC
Article 690.41(B).
IMPORTANT NOTE: When a ground fault is indicated,
normally ungrounded conductors may be grounded.
AFCI Information
The PV Link is a Photovoltaic DC Arc Fault Circuit Protec-
tion Type 1 device that incorporates an internal arc fault
circuit interrupter (AFCI) and meets the arc fault circuit
protection requirement in NEC Article 690.11.
PVRSS Information
PV Rapid Shutdown system (PVRSS) requirements have
evolved over time and are defined by the National Electri-
cal Code (NEC) in conjunction with UL 1741. Determine
what level of PV Rapid Shutdown is required for your
jurisdiction.
• 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 NEC and forward (e.g. 2020 NEC, 2023
NEC, etc) require rapid shutdown at the PV module
level for roof-mounted arrays and on the conduc-
tors leaving array.
PV Link is a PV Rapid Shutdown system equipment
(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
within the array. See PVRSS Compliance Guidelines
more information.
