Self Supply Setpoints; Sell; Export Override - Generac Power Systems PWRcell X7602 Owner's Manual

General Information
See Figure 2-12. When local demand exceeds available
solar-generated power, the battery supplies power to
support local loads. If the building requires more power
than the battery and solar can provide, then the excess
demand is drawn from the grid.

Sell

Sell mode commands the system to export all available
power to the grid. Any connected batteries drain to the
grid until their state of charge reaches the MinSoCRsrv
setpoint. Once a battery is depleted to this point, it will not
charge again until either of the following are true:
•
The solar energy available exceeds the inverter
MAX AC Power.
•
The inverter system mode is changed to a system
mode prioritizing battery backup.
See the Generac PWRcell Battery Installation Manual for
more information.

Export Override

NOTE: This feature requires CTs to be properly installed
and calibrated prior to use. For more information on CT
calibration, see the PWRcell Inverter Installation Manual.

Target Maximum Import Power
•
Maximum power imported from the grid at any point.
•
When the overall building load exceeds this setpoint, the inverter will supply
additional power from the battery and solar array to keep grid import power
below this level.
•
This maximum is not guaranteed. If insufficient battery and solar power is
available to cover the load, then the grid will supply the additional power.
Target Minimum Import Power
•
Use this setpoint to charge the battery from the grid.
•
If the overall building load is less than this setpoint, the inverter will import
power to the battery to keep the grid import power up to the setpoint.
•
If the building load is above the setpoint, the inverter will stop importing
additional power to charge the battery.
•
This minimum is not guaranteed. Once the battery is full, grid import power
may fall below this level.

Self Supply Setpoints

The TargMinImprtP and TargMaxImprtP setpoints allow
the building to deliberately import power from the grid
within certain limits. This is useful for specialized
applications, such as peak avoidance.
These setpoints are relevant to Self Supply mode only,
and are only used for specific applications. See
3: Self Supply Setpoints.
Description
NOTE: This feature is NOT intended to serve as a
means of achieving compliance to Utility interconnection
requirements. For information on export limiting settings
related to Utility compliance, see the PWRcell Inverter
Installation Manual.
When enabled, Export Override allows the user to restrict
inverter export such that excess power is not sent back to
the grid. The system limits solar power generation to
match power consumption measured by the PWRcell
CTs. This feature is suitable as a simple and easy option
for systems pending permission to operate (PTO) where
the Utility does not specify a requirement for the system
to be de-energized or otherwise disabled pending
approval. Using the Inverter control panel, a user can find
this feature on the "Mod. Settings" sub-menu within the
Inverter device page.
