Delta AC MAX Smart Charger Configuration

Delta AC MAX Smart Charger Configuration

This guide describes how to configure the Delta AC MAX Smart charger to connect to Charge HQ.

NOTE: the Delta AC MAX (non-smart) is not supported by Charge HQ as it does not support OCPP.

Supported Firmware Versions

Charge HQ has been tested with firmware version v01.25.12.00.

Step 1

Access the charger's web configuration tool as per the charger's install guide. Some tips:

  • The web configuration tool can be accessed via the charger's WiFi hotspot or Ethernet port. These tips assume the WiFi hotspot method.
  • The web configuration tool can not be accessed via the home WiFi network, even if the charger is connected to the home WiFi network.
  • The WiFi hotspot SSID is the charger's serial number, eg "JV99999999999WE". The password is printed on materials included with the charger.
  • With your device connected to the WiFi hotspot, access the web configuration tool at http://192.168.5.1.
  • Login using "admin", the password is printed on materials included with the charger.

Step 2

Navigate to Configuration tab and set: 

  • Charge Box ID: leave as serial number. Note down this value as you'll need it later - copying to the clipboard can help avoid mistakes.
  • Supervision URL: wss://ocpp.chargehq.net/ocpp16/
  • OCPP Version: OCPP1.6J
  • Offline Policy: No Authentication
  • Max Charging Current (A): the rating of the circuit. VALUE MUST BE ADVISED BY AN ELECTRICIAN
  • Communication: as per your local network eg WiFi with SSID etc.

Step 3

Proceed to the OCPP charger configuration guide. You will need the charger's serial number as noted above.

Tip: Admin Portal and OCPP

Once the charger has connected to Charge HQ via OCPP, the WiFi hotspot and the internal Ethernet port will be disabled. There is no way to access the web configuration tool whilst the charger is connected to OCPP.

To access the web configuration tool you can:

  • delete the charger from Charge HQ
  • power the charger off and on

Once the charger has finished rebooting the WiFi hotspot and Ethernet port should be available, although the hotspot may switch off after a few minutes if you don't connect to it.
