5. Setup, configuration & operation

In this section:

5.1. First use setup via VictronConnect

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).
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 NS.

EV Charger position

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

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

Alternatively, if the EV Charging Station NS 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 NS 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 NS.

Contactor active when charged

Choose whether or not the contactor within the EV Charging Station NS 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 NS. 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 NS. 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 NS 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 NS 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 NS 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 NS 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 NS 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 NS 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 NS 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 NS 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.

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 NS. This will then become the GX device that the EV Charging Station NS 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 NS.

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 NS. 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.
