Safety Rules
The manufacturer cannot anticipate every possible cir-
cumstance that might involve a hazard. The alerts in this
manual, and on tags and decals affixed to the unit, are
not all inclusive. If using a procedure, work method, or
operating technique that the manufacturer does not spe-
cifically recommend, verify that it is safe for others and
does not render the equipment unsafe.
Throughout this publication, and on tags and decals
affixed to the unit, DANGER, WARNING, CAUTION, and
NOTE blocks are used to alert personnel to special
instructions about a particular operation that may be
hazardous if performed incorrectly or carelessly. Observe
them carefully. Alert definitions are as follows:
(000001)
DANGER

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.
Failure to do so will result in death, serious injury,
equipment and property damage.

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. See the Generac PWRcell Inverter
Installation Manual for more information.
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.

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.
