Internet LED (G) is illuminated when the inverter is
connected to a router and has an IP address.
A blue Internet LED does not mean that the inverter has
a connection to the Generac server.
Shutdown Mode
NOTE: A loss of grid power will not de-energize REbus
in a PWRcell system configured to island with enabled
energy storage.
Shutdown button (E) activates a transition to shutdown
system mode.
Disabled PWRcell equipment limits output voltages to a
safe level for servicing. See Rapid Shutdown for more
information.
NOTE: The AC section of the inverter will still be
energized unless the building AC disconnect or main
service breaker is shut off.
To enter shutdown, press and hold shutdown button (E).
In shutdown mode:
• PWRcell inverter will stop sourcing power to
REbus, and immediately disable all communicating
power sources on REbus by sending a system-
wide system mode change signal.
NOTE: Successful signal transmission relies upon
proper configuration of PLM channels across REbus
devices (PV Links and Batteries).
• Shutdown LED (F) will illuminate.
• Inverter screen (A) will display REbus DC bus volt-
age and text indicting shutdown mode has been
initiated.

DANGER
Electrocution. Initiate a system-wide shutdown and turn the
PWRcell DC Disconnect Switch OFF on all connected
batteries before performing service. Failure to do so will
result in death, serious injury, or equipment and property
damage.
