Enable Grid Support in the inverter’s Setup menu and set Grid Support Volts (GSV) in the inverter’s
Advanced Settings > Grid Support menu to the desired voltage.
For instance, a GSV value of 50.6V allows the battery to discharge to roughly 20% State of Charge before
the Conext inverter connects to the grid to assist in powering local loads.
Refer to Table 7.0 for a complete set of voltages correlated with States of Charge.
DC Coupled Scenario B: Battery Discharge at Desired Times
Systems connected to utilities with Time of Use rate structures can utilize the Conext inverter’s Load Shave
function to discharge the batteries to power local loads during times when electricity rates are higher.
Enable Grid Support in the inverter’s Setup menu, in addition to programming the following parameters in
the inverter’s
Advanced Settings menu:
INVERTER – XW Pro or XW+
Advanced Settings > Grid Support
Grid Support Volts
53.3V
Sell
Disabled
Max Sell Amps
N/A (disabled)
Load Shave
Enabled
Load Shave Amps
0A
Load Shave Start
The time at which the batteries begin to discharge.
Load Shave Stop
The time at which the batteries stop discharging.
Set the Load Shave Start and Load Shave Stop parameters to the time frame during which utility rates are
high. Set
Load Shave Amps to 0A in order to draw no energy from the grid during the Load Shave time
period.
DC Coupled Scenario C: Grid-Tie with Battery Backup
Both Sell and Grid Support must be enabled in order to export energy to the grid. Consult with the
connected utility company before enabling
Sell.
Enable Grid Support in the inverter’s Setup menu. In the inverter’s Advanced Settings > Grid Support
Settings menu, enable Sell and set Max Sell Amps to the desired value.
To more effectively charge the batteries while selling to the grid, utilize the inverter’s Enhanced Grid
Support mode by setting the Grid Support Volts setting to 64V in the inverter’s Advanced Settings > Grid
Support Settings menu. In this mode, the Conext inverter does not differentiate between the solar array’s
renewable energy and the batteries’ stored renewable energy.
Refer to Table 7.0 for a complete set of voltages correlated with States of Charge.
