Installation Manual for Generac PWRCell Inverter
Selecting Inverter Compliance Setting
(optional)
By default, all Generac PWRcell Inverters ship in compli
-
ance with UL 1741 including IEEE 1547. If the system
needs to be configured to comply with a different grid
interconnection standard, activate the new configuration
before proceeding via the Installer Configuration Tool.
See
for more information.
Selecting ESS Grid Usage Mode
(Optional)
By default, all Generac PWRcell Inverters ship without
restrictions on how the PWRcell Battery (ESS) may be
charged from, or supply power to, an interconnected util
-
ity grid. If the system needs to be configured to comply
with specific utility interconnection requirements a differ
-
ent ESS Grid Usage Mode may be selected.
An ESS Grid Usage Mode is set through the Installer
Configuration Tool.
NOTE:
The ESS Grid Usage Mode is one-time settable
and, therefore, once set cannot be changed by an
installer or user without support from Generac Power
Systems.
NOTE:
There is no time allowance provided to further
change this mode after it is set.
There are two ESS Grid Usage Modes that Generac
refers to as Zero Import and Export Limiting.
Zero Import mode (CRD200 Export Only compliance)
allows the battery to export power to a connected utility
grid but will not allow the battery to be charged from the
utility grid. In this mode the battery will only be charged
by a connected REbus source such as a PV Link. Power
from the battery can supply all local loads as well as sup
-
plying power to a utility (when connected). See
for Import / Export Compliance
Export Limiting mode allows the user to restrict the export
to a connected utility grid to an Export Limit value set by
the user. When the Export Limit value is set to 0, this
mode functions as a “Zero Export” mode (CRD200
Export Only compliance) allowing the battery to be
charged from a connected utility grid but will not allow
any REbus-connected source (either from the battery or
PV) to export power to the utility grid. Configured this
way, the battery can be charged by a connected REbus
source and/or a utility grid source but no power will be
exported to the utility.
See
Setting for Import / Export Compliance
information.
NOTE:
Both ESS Grid Usage Modes rely upon proper
CT functionality. Ensure CTs placement is correct for the
system configuration. Ensure CTs are calibrated and
functioning
Enabling REbus Devices
NOTE:
All PWRcell devices are enabled and configured
individually through the PWRcell inverter control panel.
Following installation, the inverter must be enabled
before all other REbus devices.
To enable the inverter:
1.
See
. Use the right arrow key to scroll
the inverter device page.
2.
Verify inverter status reads disabled.
