About PV Link
The PV Link is a nonisolated, interleaved DC-DC convert-
er 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 bidirectional power line com-
munication (PLC) protocol for communicating with inver-
ters and other devices on REbus.
PV Link is intended for use with 60-cell, 72-cell, or 96-cell
residential DC PV modules. PV modules must not require
positive or negative grounding as this would interfere with
010024
PLC communications.
NOTE: Other PV 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 fac-
tory and is designed for attachment to standard PV rack-
ing. 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 sat-
isfies 2017, 2020, and 2023 NEC 690.12 PV Rapid Shut-
down system (PVRSS) requirements. 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.
