Communication

All communication between REbus devices takes place
over the REbus conductors using Power Line Carrier
(PLC) communication. No additional communication wir-
ing or equipment is required for communication between
PWRgenerator and PWRcell Inverter.

Inverter Control Module

See Figure 3-12. In addition to an on-board control
panel, PWRgenerator may also receive commands and
setting changes from the PWRcell Inverter control mod-
ule (ICM) located on the front of the PWRcell Inverter.
See PWRcell Inverter owner's manual for more informa-
tion on settings and display screens.

Auto Start/Stop State of Charge (SoC) Setpoints

There are two user-adjustable PWRgenerator setpoints
which dictate when the PWRgenerator will automatically
be prompted to start and stop while in AUTO mode: Auto-
StrtSoC and AutoStopSoC. These setpoints can be
adjusted through the Mod Settings menu on the PWR-
generator device page on the ICM.
Setpoint
Battery SoC where PWRgenerator is
prompted to start and provide power.
GWRgenerator must be in AUTO to use
AutoStrtSoC
this setpoint.
Battery SoC where PWRgenerator is
prompted to stop providing power and
enter a standby state. PWRgenerator
AutoStopSoC
must be in AUTO to use this setpoint.

PWRgenerator Start/Stop Commands

PWRgenerator can be manually commanded to start or
stop from the PWRgenerator device menu. The following
criteria must be met for the commands to take effect:
•
PWRgenerator must be set to AUTO at generator
control panel.
•
PWRcell Inverter must be in Island Mode.
