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 PWRcell Inverter, PV array, and / or other
REbus enabled batteries.
System Operational Modes
The PWRcell system has several operational modes
available for various installation configurations, markets,
and applications. Operational modes are selected
through the 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 complete instructions on
configuring the entire system for each operational mode.
Inverter Control Panel
See Figure 2-6. The battery is controlled through the
PWRcell Inverter control panel. Use the inverter control
panel to enable or disable the battery, and to set the
operational mode for the system. See the Generac
PWRcell Inverter Owner’s Manual for more information
on settings and display screens.
