Step-by-Step: Changing the Back Office Configuration

Preparation (if using a SIM card)

  1. Power off the charger.
  2. Insert the SIM card provided by your new back office provider into the SIM slot on the control board.
  3. Power the charger back on.

Set the Back Office Preset

  3. Select ‘Stand-alone’ and restart the charger.

Configure Network Profiles

  1. Return to the ‘Connectivity’ tab.
  2. Set the ‘Network profile connection attempts’ value and click ‘Save’.
  3. Open ‘Network Profile 1’ and set the priority (1, 2, or ‘Not used’).
  4. Repeat for other profiles.
  5. If using a mobile connection, configure the ‘Mobile’ tab.
  6. Click ‘Save’ and restart the charger.

Verify the Connection

  1. Go to ‘Live Monitoring’.
  2. Check if the ‘OCPP Boot Notification State’ shows ‘ACCEPTED’.

 

Manual Configuration (if preset is not available)

  1. In the ‘Back Office Preset’ dropdown, select ‘Manually enter backend settings’.
  2. Under the appropriate network profile, enter:
    • Protocol: OCPP 1.6
    • Server domain and port
    • Back office path
    • Security profile level
    • APN name, user, password
    • SIM PIN (if applicable)
  3. Configure the ‘Mobile’ tab if needed.
  4. Click ‘Save’ and restart the charger.
  5. Check the connection in ‘Live Monitoring’.

 

Installing a Root Certificate (for WSS/HTTPS)

  1. In the ACE Service Installer, go to the ‘General’ tab and click ‘Upload Firmware’.
  2. Select the file Rootcertificate.fwi.
  3. Click ‘Start Upload’.
  4. Wait for the upload to complete and reboot the charger.
  5. Check the connection in ‘Live Monitoring’.

 

Switching to Stand-alone Mode

  1. Power off the charger and remove the SIM card.
  2. Power the charger back on and select ‘Stand-alone’ in the ‘Back Office Preset’ list.
  3. In the ACE Service Installer:
    • Go to ‘Authorization’ > set ‘Offline action’.
    • Set ‘Authorization Mode’ to RFID or Plug & Charge.
    • If using Plug & Charge, enter the Plug & Charge ID (e.g., ACExxx).
  4. Reboot the charger.

 

Frequently Asked Questions (FAQ)

What does ‘TLS error: Handshake missing’ mean?

This indicates a missing root certificate. Install it as described above.

What should I do if I see HTTP error 103 or 104?

Contact your back office provider. These errors cannot be resolved from the charger side.

How do I know if the connection is successful?

Check the ‘OCPP Boot Notification State’ in ‘Live Monitoring’. It should say ‘ACCEPTED’.

What if my SIM card doesn’t connect?

Ensure the SIM is active and supports 4G. Contact your provider if needed.

What’s the difference between Security Profile Level 2 and 3?

Level 2 uses TLS with basic authentication; Level 3 also requires a client certificate.
