17 of 20 - Self Consumption with Backup Loads and Zero Net Export

The default operational mode of the Solis Energy Storage Inverter is Self Consumption Mode. If no other mode has been ever been selected, then Self Consumption is the mode that the inverter is currently set to. 

For more details on Self Consumption Mode see article 12 on Self Consumption. 

From here on the assumption is that the system is operating in Backup Mode + Time Charging or Off-Grid modes. The steps below can be performed if there is no grid power going to the inverter. This article will explain how to revert back to Self Consumption mode if Time Charging or Off Grid has been previously selected. This will also cover Zero Net Export with backup loads.

If the inverter is set to Time Charging:

  1. Enter the Advanced Settings menu using 0010 (down, down, up, enter) and then go down to Storage Energy Set
  2. Select Storage Mode Select and then select Time Charging
  3. Change Optimal Income to: Stop - press ESC and then when Save & Send is highlighted press Enter
    1. This causes the inverter to revert back to the factory default, which is Self Consumption mode
  4. If this is done during the day when there is plenty of sun the following will happen:
    1. PV will power the backup loads panel
    2. Excess PV power will charge the battery
    3. If there is no grid connected, there will be no power being exported
    4. All of the backup loads will be supported by the PV during the day and the battery at night

If the inverter is set to Off Grid Mode:

  1. Go to Advanced Settings > Storage Energy Set > Storage Mode Select > Off Grid Mode
  2. Select OFF and then press ESC to go back to the main menu after pressing Enter on Save & Send
    1. This causes the inverter to revert back to the default - Self Consumption mode

Zero Net Export:

  1. Go to Advanced Settings, go to Export Power Set and press Enter
  2. Press Enter on Backflow Power 
  3. Change the number to +00000 and press Enter - "Done!" will appear on the screen
  4. Press ESC a few times to get back to the main screen
  5. On the screen, there is an arrow going from the meter on the right side of the screen to the electrical tower icon (grid)
    1. This represents power being exported to the grid
    2. The number to the left of the arrow is the amount of power (kW) being exported
  6. The power being exported should drop to zero within several seconds
  7. All of the PV power will now go to either the backup loads or to the battery
