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 Enanced Grid
Support mode by setting the Grid Support Volts setting to 64V in the inverter’s Advanced Settings >
Grid Suppport 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.

Notes:
1. Maximum setting of 48V limited by some inverter firmware is below the recommended setting.
2. Per PHI 3.8 Battery – These setting are calculated by multiplying the nominal per battery value times the # of batteries.
3. Levels are typical @ 25C and may need adjusting at temperature extremes.
4. When performing rapid deep charge/discharge cycles the battery should be allowed to "rest" 15 minutes in between.
