5. Setup, configuration & operation

In this section:

5.1. First use setup via VictronConnect

Note

Note that operation via VictronConnect requires Bluetooth to be enabled. Bluetooth is disabled on devices shipped with firmware version 1.23 or earlier. In order to enable Bluetooth for these devices, it is mandatory to first go through the First setup via Wifi access point procedure and then activate it via the Networks menu. Devices shipped with firmware version 1.24 and higher have Bluetooth enabled by default.

The initial setup is required when the EVCS is new and has yet to be configured or after it has been reset to factory defaults.

Preparation

Open VictronConnect and find the entry for your EVCS (EVCS-HQXXXXXXXXX).
Tap on EVCS. This will start the pairing dialogue. Enter the pairing code which is either 000000 or a uniqe number on a sticker inside the housing.
If the pairing was successful, the status page would appear; ignore the warning for now (using the EVCS is not yet possible) and tap the cog wheel icon in the upper right to open the Settings page so that the initial setup can be performed.

Step 1 of 3: Configure WiFi access

One of the following parameters must be changed to complete the first setup and start using the EV:

Either confirm the WiFi mode AP (the EVCS provides its own access point) - all necessary parameters are already pre-filled. The AP passphrase corresponds to the password as stated on the sticker inside the EVCS.
Or choose Station mode to connect the EVCS to your local network/router. If you already know the network name (SSID), you can enter it manually. Alternatively, hit SCAN to find nearby networks, select your desired network, and enter the access password.

Step 2 of 3: Change web access credentials

This step is necessary to ensure secure access to the web interface. The default username is "admin". The default password corresponds to the one on the sticker inside the EVCS. We recommend setting up your own password and username.

Step 3 of 3: Set the maximum charging current

Set the maximum charging current with which the EVCS is allowed to charge (range: 10A - 32A).

Reboot EVCS:

System reboot: tap the "REBOOT" button to reboot the EV Charging Station.

EV Charger position

Select the position that the EV Charging Station is wired in the system.

If the EV Charging Station is wired anywhere before the Inverter / Charger then select the "Inverter AC in" option.

Alternatively, if the EV Charging Station is wired after the Inverter / Charger or is wired after an Inverter then choose the "Inverter AC out" option.

EV Charger autostart

Choose whether or not the EV Charging Station starts automatically when the charging cable is connected to the EV.

Select "Enabled" to have charging start automatically when the charging cable is connected to the EV.

Select "Disabled" if you don't want charging to start automatically. In this case charging needs to be started manually by pressing the "Start" button from the Overview page. This can help to prevent unauthorised use of the EV Charging Station.

Contactor active when charged

Choose whether or not the contactor within the EV Charging Station remains closed or opens when the EV is charged but the cable is still connected.

Select "Enabled" for the internal contactor to remain closed when the EV is charged. For example, this can be useful if you would like to pre-condition the cabin air using electricity from the charging source rather then the EV battery.

Select "Disabled" if you want the internal contactor to open when the EV is charged. This has the effect of disconnecting the EV from the supply as if the charging cable is removed.

CP Calibration

A Type 2 EV charging cable contains a signal line called the "Control Pilot" (CP). This is a bi-directional signal to enable communication between the EV and an EV charging station such as the EV Charging Station. It is important that the CP line is calibrated to ensure proper communication between the EV and its charger.

Tap the "CALIBRATE" button to begin calibrating the CP line.

A confirmation box will pop up. Tap "NEXT" if you are sure that you want to recalibrate the CP line.

Follow the instructions on the next screen and ensure that the EV is connected to the EV Charging Station. Tap "NEXT" to confirm and allow the CP line calibration to begin. Wait until the calculations are finished.

Once the calibration process is complete then a "Success!" message will be shown.

Tap on "CLOSE" to apply the new calibration calculations or "Reset" to reset them.

GX device communication

The GX device settings page is accessible from the General settings page.

Communication: Enable or disable communication with a GX device in the system.
Start charging at backup battery SOC: The minimum backup battery SOC before the EV Charging Station starts charging in Auto mode.
Stop charging at backup battery SOC if off grid: When off-grid or the grid is not available, then the EV Charging Station will stop charging when the backup battery SOC falls below this level.
Allow Battery/Grid power for Auto mode: Enable this setting to allow Auto mode to continue charging the EV at minimum current even if there is insufficient excess solar power. This helps to minimise automatic charging enable/disable cycles when in Auto mode. Note: The EV Charging Station cannot decide if the energy comes from the battery or grid, this is up to the inverter/charger in the system.
Battery/Grid power timeout: If the above setting is enabled then this is the maximum continuous amount of time that the EV Charging Station will draw power from the battery or grid.
Overload protection: When enabled, this setting will read the overload status of the system inverter. In the event of an overload then the EV Charging Station will reduce its charging current to minimum and wait about 5 seconds. If the inverter overload condition is still active then the EV Charging Station will stop charging. EV charging will resume a short period of time after the inverter overload condition has cleared.
If multiple overload events are detected within a certain time period the the EV Charging Station will reduce the charging current by 10%.
The same applies to grid-tied system where an enforced grid current limit is exceeded.
A warning will be displayed in VictronConnect or in the EV Charging Station if charging power is reduced or if charging is interrupted.
Input current limit: This displays the enforced grid current limit which is applied to grid-tied systems.
IP Address: Displays the IP address of the GX device. Tap on the "IP Address" line to change it.
VRM Portal ID: Displays the VRM portal ID. Tap on the "VRM Portal ID" line to change it.

Check communication: Tap the "CHECK" button to check the communication between the EV Charging Station and the GX device using the IP address set above.
Check result: Shows if the communication check to the GX device has passed or failed.
If the communication check fails then verify that the GX IP address specified is correct or use the "DISCOVER" button to search for a local GX device as below.

Device discovery: Tap the "DISCOVER" button to allow the EV Charging Station to automatically discover any GX devices on the local network.
Discovery result: Any GX devices which have been found by Device discovery will be listed.
Tap "ADD" to pair the desired GX device to the EV Charging Station. This will then become the GX device that the EV Charging Station communicates with and its details will be populated in the IP Address and VRM Portal ID fields.

Modbus TCP settings

The ModbusTCP Server settings allow enabling the IP whitelist and to add GX devices' IP addresses to be added to it.

With the whitelist enabled, only the IP addresses added to the whitelist will be able to communicate with the EV Charging Station.

For security reasons it is highly advisable to enable the TCP whitelist and to add only the GX devices which need to communicate with the EV Charging Station. This may also be a requirement from grid operators in some countries.

Enable IP address whitelist: Enable or disable the IP whitelist feature.
Add IP to whitelist: Tap the "ADD" button to populate the whitelist with trusted IP addresses.

Date & Time

Region: Select your time zone region.
Offset: If UTC region is selected then it will be necessary to enter the correct offset for your time zone.

Partial and full reset to factory defaults using the DEF button inside the device:

Warning

The procedure described below should only be performed by qualified personnel as this process requires the EV Charging Station to be powered. Working under high voltage is very dangerous and can be fatal if used incorrectly.

Partial reset
A partial reset only resets the admin password and Bluetooth PIN code, all other settings are preserved.

Open the unit by removing the backing plate. Be careful not to touch the high-power parts inside the unit. Only the area around the DEF button is safe.
For a partial reset, press the DEF button (see the image in EV Charging Station setup web interface for its location) for more than 5 seconds but less than 15 seconds.
After releasing the DEF button, the RGB light ring starts blinking green rapidly to indicate that the partial reset is in progress.
Note that if your mobile device was successfully paired before resetting the PIN code, it is still possible to connect to the EVCS via VictronConnect as long as it is not unpaired. All other devices must be paired with the default PIN code as described in the VictronConnect Setup, configuration & operation section.
If you were logged in to the web interface using a browser prior to the partial reset, the admin password reset for that connection will not take effect until you log out of the web interface. All other devices require the default password printed on the sticker inside the device. until a new password has been assigned; see Access menu for details.
Mount the backing plate onto the device and tighten the screws.
Assign a new admin password; see Access menu for details.

Full reset

Open the unit by removing the backing plate. Be careful not to touch the high-power parts inside the unit. Only the area around the DEF button is safe.
For a full reset, press the DEF button (see the image in EV Charging Station setup web interface for its location) for more than 15 seconds until the RGB light ring starts blinking blue rapidly to indicate that the full reset is in progress, then release the button.
