Connecting Ethernet; Current Transformers (Cts) - Generac Power Systems PWRcell X7602 Installation Manual

Electrical Connections
NOTE: See
Figure 5-6. On systems that do not include battery storage but battery storage is expected in the future,
install a protected loads panel during inverter installation. The protected loads panel will be fed by the grid while the
system operates in Grid Tie mode.

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
the Inverter Ethernet jack location.
•
Use an appropriate cord grip or strain-relief
connector when running Ethernet cable with a
conduit.
•
Cat 5 for Ethernet should not exceed 328 ft (100
meters) in length.
•
Basic high speed broadband internet service with 5
Mpbs upload/download required.
•
Inverters connected by a router to a DHCP network
will automatically detect settings.
•
For manual IP setup, see
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)

Equipment damage. Only connect CTs provided by
Generac. Never connect to any other CTs. Connecting
to other CTs could result in equipment damage.
Current transformers (CTs) are required to configure Self
Supply mode, the Export Override setting, and to enable
Import / Export limiting capability. CTs are also required
when setting a specific ESS Grid Usage Mode. CTs also
for
allow the inverter to provide information on utility
consumption through the PWRcell inverter control panel
and the PWRview monitoring app.

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.
