General Information
About Generac PWRcell Battery
The Generac PWRcell Battery is the storage component
of the Generac PWRcell system. The Generac PWRcell
Battery
can
be
used
applications, such as self-supply, rate arbitrage and clean
backup power. The Generac PWRcell Battery is
designed to work seamlessly with Generac PV Link
Optimizers and the Generac PWRcell Inverter to form the
Generac PWRcell system for grid-tie solar-plus-storage.
All Generac PWRcell products use the REbus™ 380VDC
nanogrid to connect energy sources, storage and loads.

Communication
All communication between REbus devices takes place
over the REbus conductors using Power Line Carrier
(PLC) communication. No additional communication
wiring or equipment is required for communication
between a Generac PWRcell Battery, inverter, PV array,
and/or other REbus enabled batteries.
System Operational Modes
The Generac PWRcell system has several operational
modes available for various installation configurations,
markets, and applications. Operational modes are
selected through the Generac PWRcell Inverter control
panel. The inverter prioritizes the distribution of power
differently based on the selected operational mode.
See the Generac PWRcell Inverter installation and
operation
manuals
for
configuring the entire system for each operational mode.

The REbus nanogrid automates the flow of power to
enable plug-and-play setup and operation of Generac
solar
PWRcell equipment.
In
Figure
2-4, a REbus compatible Generac PWRcell
Inverter (E) is directly connected to Generac PV Link
Optimizers (B) and Generac PWRcell Battery (E) on the
DC (REbus) line (D). To the right of the inverter are AC
lines: 240VAC or 208VAC for grid and home loads (G),
and protected load (H) support up to 50A.
