20 Installation Manual for Generac PWRCell Inverter
Connecting Ethernet
IMPORTANT NOTE: Generac requires all PWRcell
system components to be connected to the Internet
and to maintain such connection throughout the war -
ranty period. Internet connectivity is established via
the PWRcell inverter. By installing the PWRcell
inverter and connecting it to the Internet, Customer
agrees that Generac may remotely monitor the use
and condition of the system and update the system's
software and firmware, as necessary, without further
notice. If the PWRcell system loses Internet connec -
tion for an extended period, Generac may not be able
to provide important remote upgrades. In such
cases, Generac may not be able to honor the full war -
ranty.
•
See
PWRcell Inverter Wiring Compartment
for
the Inverter Ethernet jack location.
•
Use an appropriate cord grip or strain-relief
connector when running Ethernet cable with a
conduit.
•
Inverters connected by a router to a DHCP network
will automatically detect settings.
•
For manual IP setup, see
Manually Configuring
IP Settings .
NOTE: It is the installer’s responsibility to verify the
Internet connection is reliable and secure. Generac
recommends using a hardwired connection to provide
Internet connectivity. Generac does not support using
any wireless or power line carrier network devices. Use
these devices at your own discretion.
NOTE: Ethernet cable run must be dedicated for the
inverter. This cable may not be daisy-chained to another
device, including another PWRcell inverter.
Current Transformers (CTs)
Current transformers (CTs) are required to use the Self
Supply mode and to enable Import / Export Limiting
capability. CTs are also required where setting a specific
ESS Grid Usage Mode. CTs also allow the inverter to
provide information on utility consumption through the
PWRcell inverter control panel and the PWRview
monitoring app.
Connecting Current Transformers
•
See Figure 5-7 . Install CTs around the main
service conductors between the service meter and
point of interconnection with subsequent service
entrance panel/device.
•
Install one current transformer per phase:
– Install two CTs for split phase grids.
– Install three CTs for three-phase grids.
