Set Export Override (optional)

NOTE: This feature requires CTs to be properly installed
and calibrated prior to use. For more information on CT
calibration, see
Current Transformers
NOTE: This feature is NOT intended to serve as a
means of achieving compliance to utility interconnection
requirements. To set for zero export compliance or export
limiting, see
Set Import
(optional).
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
powered-off or otherwise disabled pending approval.
When enabled, Export Override allows the user to restrict
inverter export such that excess power is not sent back to

Enable REbus Devices

DANGER
Electrocution. Never enable any device during an
installation or while wires are exposed. Doing so
will result in death, serious injury, or equipment or
property damage.
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 6-7. Use the right arrow key to scroll to
Figure
the inverter device page.
2. Verify inverter status reads disabled.

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.

the grid. The system limits solar power generation to
match power consumption measured by the PWRcell
CTs. Using the Inverter control panel, a user can find this
feature on the "Mod. Settings" sub-menu for the inverter.

Adjusting for Peak Shaving

The TargMaxImprtP and TargMinImprtP setpoints allow
the building to deliberately import power from the grid
within certain limits. This is useful for specialized
applications, such as avoiding peak demand charges.
These setpoints are relevant to Self Supply mode only,
and are only used for specific applications. See
2: Self Supply Setpoints.
