source, if not avoided, will result in death
or serious injury.
(000604)
DANGER
Electrocution. PWRcell Battery front cover should be
removed by a qualified technician only. Removing
the front cover could result in death, serious injury,
equipment or property damage.
(000145)
DANGER
Electrocution. In the event of electrical accident,
immediately shut power OFF. Use non-conductive
implements to free victim from live conductor. Apply
first aid and get medical help. Failure to do so will
result in death or serious injury.
(000599)
Electrocution. Turn battery disconnect OFF and
de-energize REbus before touching terminals.

equipment and property damage.
DANGER
(000152)
DANGER
Electrocution. Verify electrical system is
properly grounded before applying power.
Failure to do so will result in death or serious
injury.
Safety Shutdown
(000600)
DANGER
Electrocution. Initiate a system-wide safety shutdown
and turn PWRcell Disconnect Switch OFF on all
connected batteries before performing service. Failure
to do so will result in death, serious injury, equipment
and property damage.
NOTE: A loss of grid power will not de-energize REbus
in a system configured to island or provide backup power.
See Figure 1-1. Shutdown button (A) on the Generac
PWRcell Inverter control panel activates Safety
Shutdown. Safety Shutdown signals connected devices
to shutdown and limit output voltage to a safe level. An
external shutdown button may also be installed, given
appropriate labeling.
NOTE: An additional remote safety shutdown may be
required to be installed for local compliance.
To enter Safety Shutdown, press and hold Shutdown (A).
Safety shutdown LED (B) will illuminate and LCD screen
(C) will indicate Safety Shutdown has been initiated.

be transmitted to all devices connected to REbus. In
Safety Shutdown:
•Generac PWRcell Inverter will disconnect from the
grid.
•Generac PWRcell Inverter will stop sourcing power
to REbus, and immediately disable all sources on
REbus by sending a global shutdown signal.
•All Generac PV Link optimizers will disconnect
their output.
•Safety Shutdown LED (B) will be illuminated to
show that the inverter has entered safety shut-
down. REbus DC bus voltage will be displayed on
the inverter screen.

About Generac PWRcell Inverters
The Generac PWRcell Inverter connects to the Generac
PV Link™ and Generac PWRcell Battery to form the
Generac PWRcell system for grid-interactive solar-plus-
storage.
Upon the loss of grid power, Generac PWRcell Inverters
disconnect from the grid and provide AC power to
support protected loads when configured to do so.
All Generac PWRcell products use the REbus™ 380
VDC nanogrid to connect energy sources, storage, and
loads. The REbus nanogrid automates the flow of power
to enable plug-and-play setup and operation of Generac
PWRcell equipment. For more information about REbus,
visit www.generac.com.
In Figure 2-3 Generac PWRcell Inverter (E) is directly
connected to Generac PV Link (B) and Generac PWRcell
Battery (C) on DC (REbus) line (D). To the right of the
inverter are AC lines: 120/240 VAC for grid and home
loads (G), and protected loads (H) support up to 50 A.
