About PV Link
The PV Link is a nonisolated, interleaved DC-
DC converter that boosts PV input to a higher
voltage and outputs it to REbus™, Generac’s
regulated 380 VDC bus. The PV Link provides
droop-mode power management, enabling
multiple optimizers to connect in parallel on a
common bus. Its DC output carries a bidirec -
tional power line communication (PLC) proto -
col for communicating with inverters and other
devices on REbus.
PV Link is intended for use with 60-cell, 72-
cell, or 96-cell residential DC solar modules.
Solar modules must not require positive or
negative grounding as this would interfere with
PLC communications.
NOTE: Other solar modules may be suitable
for use with PV Link, contact Generac for
more information.
The PV Link is sealed in a type 4X enclosure
at the factory and is designed for attachment
to standard PV racking. Safety features
include ground fault detection and interruption
(GFDI), arc fault detection, circuit interruption
(AFCI), and rapid shutdown capability.
About Generac SnapRS
SnapRS is an inline PV rapid shutdown device
that satisfies 2017 and 2020 NEC 690.12 PV
rapid shutdown system (PVRSS) require -
ments. When used with PV Link, SnapRS
devices limit all controlled conductors within
an array’s 1 ft (305 mm) boundary to 80 VDC
or less within 30 seconds of rapid shutdown
initiation.
GFDI Information
The PV Link’s internal ground fault detector
and interrupter (GFDI) is designed to trip at
240 mA (± 40 mA) of PV DC voltage ground
current. Ground faults are displayed on the
