Grid Support Enabled, Sell Enabled
In this mode, all available excess DC power is first used to power local loads. Any
remaining power is exported to the utility grid.
Note: To comply with anti-islanding requirements, in a grid tied AC coupled system,
change the AC1 Transfer Delay setting under AC Transfer Configuration to
300seconds.
Sell Block
The sell block feature halts the export of energy to the grid connected to AC1 for a period
of time each day. This period of time is defined by the Sell Block Start and Sell Block
Stop settings. Sell Block can be useful in managing the self consumption of renewable
energy.
Note: Sell block will not block selling from an AC coupled inverter.
Grid Support and Battery Charging
Charge Cycle Settings
With the charger enabled, the Conext XW Pro enters grid support mode only after
completing a charge cycle when it is first powered up or reconnected to the grid. Unless
an external BMS is installed with Charge Cycle set accordingly, set the Conext XW Pro
Charge Cycle to two-stage (default) to allow grid support to function immediately after the
absorption charge stage is completed. See "Charger Settings" on page59 for more
information.
NOTE: Only the Conext XW Pro needs to be set to two-stage charging. The Conext
MPPT solar charge controllers can remain set for three-stage charging. The Conext XW
Pro should be set in two-stage charging and the charge controllers set in three- stage for
solar charging to occur properly. Alternately, charger block can be used to for correct
charging. See "Charger Settings" on page59 for further information.
Grid Support modes
Grid Support can be configured to operate in one of two modes:
n Grid Support with DC Sources Not Communicating Over Xanbus
n Enhanced Grid Support with Conext MPPT Solar Charge Controllers
At this time, State of Charge Control is not supported with any sort of DC-
coupled sources.
Grid Support with DC Sources Not Communicating Over Xanbus
This setup is suitable for use with DC sources (such as wind turbines, DC generator
sets, fuel cells, and so on) that do not communicate with the Conext XW Pro through
Xanbus or for mixed systems which have both Xanbus-connected Conext Solar Charge
Controllers and other DC sources (such as those listed above). Grid Support
Voltage is set 0.5 volts below the voltage provided by the DC source (typically the float
voltage setting of the DC source or charge controller). See Figure 17 on page 71.
Schneider Electric does not provide support for these energy sources.
