6 of 20 - Net Export without the Battery

Note: this step is for when the battery is off 

  1. Press the Enter button
  2. Go down to "Advanced Settings" and press Enter
  3. Put in the password "0010" by pressing Down, Down, Up, Enter
  4. Press Down until "Export Power Set" is highlighted and press Enter
  5. "Backflow Power" should be highlighted, press Enter
  6. The value shown here is how much power the inverter will export (backflow) to the grid
  7. Maximizing exported power
    1. You will first need to determine the power size of the inverter 
    2. Check the nameplate on the left side of the unit and look for "Model Number"
      1. Example: RHI-1P5K-HVES-5G
    3. The power size is the number next to "K" so in the example above, the inverter is a 5 kW unit
    4. Using the Up and Down buttons, match the "Backflow Power" value on the screen to the power size
      1. If it is a 5 kW inverter then the value should be "+5000W"
    5. Press Enter and the screen will say "Done!" 
    6. You may now press Esc a few times to return to the main menu or main screen
  8. Eliminating exported power (zero-net export)
    1. Press the Down button until the "Backflow Power" value is "+00000W"
    2. Press Enter and the screen will say "Done!"
    3. You may now press Esc a few times to return to the main menu or main screen
  9. Ensure that you have the Acrel meter, CTs, and meter communication wire installed correctly
  10. Wait approximately five to ten minutes
  11. On the screen, between the transmission tower and house icons there will be a number followed by "kW"
    1. This kW value is the amount of power being exported/imported to/from the grid
    2. The arrow direction indicates whether power is being exported or imported
      1. Export = Arrow pointing towards the transmission towers 
      2. Import = Arrow pointing towards the house
  12. In zero-net export mode, this value should read "0.0kW"
    1. If it does not read "0" check the Backflow Power setting again - it is possible that the change was not saved 
  13. In maximum export mode, the value should read the difference between the solar generation value and house consumption
