Installation Manual for Generac PWRCell Inverter
Connecting Ethernet
IMPORTANT NOTE:
Generac requires all PWRcell sys-
tem components to be connected to the Internet and to
maintain such connection throughout the warranty
period. Internet connectivity is established via the PWR-
cell Inverter. By installing the PWRcell Inverter and con-
necting it to the Internet, Customer agrees that Generac
may remotely monitor the use and condition of the sys-
tem and update the system's software and firmware, as
necessary, without further notice. If the PWRcell system
loses Internet connection for an extended period, Gen-
erac may not be able to provide important remote
upgrades. In such cases, Generac may not be able to
honor the full warranty.
•
See
Generac PWRcell Inverter Wiring
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 the Generac PWRcell
Inverter Owner’s Manual.
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.
Current Transformers (CTs)
Current transformers (CTs) are required to use the Self
Supply mode and to enable Zero Export capability. CTs
also allow the inverter to provide information on utility
consumption through the Generac PWRcell Inverter
control panel and the PWRview monitoring app.
Connecting Current Transformers
•
See
. 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.
