How to change the OCPP server URL on a V2C charger

A V2C charger that speaks standard OCPP can be connected to any platform by changing one setting. Here is where that setting lives on Trydan, Trydan Pro, exactly what to enter, and where people usually get stuck. Written by a platform (askacharge.com), but the procedure works for any.

Where the setting lives

In V2C Cloud: on the v2c.cloud website (left menu → OCPP) or in the app, inside the charger's configuration → OCPP.

Step by step

  1. Create a V2C Cloud account (app or web) and pair the Trydan. It must be connected over Wi-Fi: chargers connected any other way do not appear in the OCPP section.
  2. Open OCPP and tap the green pencil to edit.
  3. In the central station URL enter your brand's base URL (below, without the identifier): the Trydan appends its own OCPP ID.
  4. Do not change the OCPP ID the charger ships with: register it as it is on askacharge.com. Changing it can break the communication.
  5. Tick the OCPP box and save. It shows as connected in the panel within a minute.

What to enter to connect it to askacharge.com

OCPP server URLwss://askacharge.com/askacharge/ocpp/your-brandyour-brand is your brand's identifier on askacharge.com (shown under Chargers → Add, with the full URL ready to copy). The charger appends its own identity; if your unit only has a URL field and no identity field, enter the full URL: …/ocpp/your-brand/identity.
Charge point identityThe same one you register in the panel when adding the charger. Case-sensitive. With V2C, the serial number is the easiest choice.
PasswordBlank by default. If you enable the charger's OCPP credential in the panel (recommended for units exposed to the internet), the username is the identity and the password is the one the panel generates: OCPP Security Profile 2.
ProtocolOCPP 1.6J (JSON) or OCPP 2.0.1. Subprotocol ocpp1.6 / ocpp2.0.1.
Before connectingThe charger must be registered in the brand with that identity; otherwise the server rejects the connection. Register under Chargers → Add.

Where it usually fails

If your brand isn't here

The procedure is always the same; what changes is where the setting lives: look in the manufacturer's app, in the charger's web interface (by its IP) or in the installer software for a section called OCPP, Back office, Central System or Server. You need to be able to enter the URL and, nearly always, the identity. If the field is locked or missing, the manufacturer has tied the charger to its own platform: read what to do when the manufacturer locks or switches off its server.
