Installation Manual for Generac PWRCell Inverter
1.
Close the AC backfeed breaker to supply AC
power to one PWRcell Inverter AC Grid Input/Out
-
put Terminals. This will allow the inverter to ener
-
gize and illuminate the Inverter control panel.
2.
Perform
steps 1-8.
3.
Modify the PWRcell inverter PLM Channel to 0.
NOTE:
PLM Channel 0 is a catchall channel. Only use
for inverters during programming. Do not set REbus
devices to channel 0. Do not leave inverter on channel 0.
4.
Choose a channel from 2 -12 to use as the only
number for addressing all devices on the system.
The goal is to address the system to its own unique
channel across all devices.
NOTE:
Do not leave any device, including the inverter,
on channel 0 or channel 1 by the end of the process.
5.
Use arrow keys to navigate to all REbus devices
(expect REbus Beacon) to change the PLM chan
-
nel.
6.
Access Mod. Settings for each device and change
the PLM channel to the chosen channel (step 4) for
that system. See device installation manual for
specific instructions.
7.
Modify the PLM channel setpoint for the PWRcell
inverter to match the PLM channel its REbus
devices were set to in the previous step.
NOTE:
Be sure to click Save at the bottom of the menu
after modifying the channel on each device.
8.
De-energize inverter. Once the inverter is de-ener
-
gized, repeat steps 1-7 for the next system.
NOTE:
It may take a few seconds for the inverter screen
to power off due to capacitance in the power core. Wait
until the screen goes blank before energizing the next
inverter system.
9.
After programming each system separately, re-
energize all PWRcell inverters by closing their AC
Grid backfeed breakers, enable the inverters, and
all REbus devices.
PLM Cross-talk Recovery Procedure
For each PWRcell Inverter that has cross-talked, perform
the following procedure to clear the foreign devices from
the display:
1.
De-energize all but one inverter.
2.
Access the Installer Configuration Tool using the
instructions below.
3.
Navigate to the ‘Inverter’ using the Installer Tool
and select PWRcell Configuration.
4.
Select Clear Display to wipe the screen of that
inverter of unwanted devices from other systems
on site.
5.
Follow steps 1- 8 for Multiple Inverter System Com
-
missioning. See
6.
Proceed to next cross-talked inverter and repeat
the procedure.
Installer Configuration Tool
The Installer Configuration Tool allows configuration and
provisioning of Generac PWRcell systems from a smart
-
phone or laptop. The interface allows installers to config
-
ure basic settings, set inverter compliance, generate a
compliance report, and understand system performance.
The interface is only available on Generac PWRcell sys
-
tems with a REbus Beacon installed. Close proximity to
the Beacon is required for use. It is not possible to
access this tool remotely. 45 minutes after being acti
-
vated, the Beacon’s WIFI signal will time out and may
need to be reactivated.
NOTE:
All PWRcell inverters come with a REbus
Beacon pre-installed.
Accessing the Installer Configuration Tool
1.
Navigate to the Beacon device page on the PWR
-
cell inverter control screen and press the center
button.
2.
Select Installer Tool from the menu and click Con
-
firm
.
This will activate the Beacon’s Wi-Fi network.
3.
Use a smartphone or laptop to connect to the Wi-Fi
network SSID titled:
REbus_Beacon_xxxx
where
xxxx
is the last 4 digits of the Beacon’s RCP num
-
ber.
NOTE:
The Beacon’s RCP number can be found on the
front of the Beacon located inside the inverter, as well as
on the Beacon device page through the inverter’s screen.
To find this number through the inverter’s screen press
the center button on the Beacon device page. The RCP
number will be displayed at the bottom of the menu
screen.
4.
Type in the password (labeled “CODE”) for the
REbus Beacon's Wi-Fi network.
NOTE:
The code for the REbus Beacon’s Wi-Fi network
is located on the back of the Beacon inside of the
inverter. The Beacon is mounted on the upper left-hand
sidewall of the inverter housing. Unstick the Beacon to
view the code labeled on the back.
NOTE:
Where utility requirements contain provisions for
security against adjusting compliance settings, consider
removing code label for the Beacon after successful
commissioning.
