Manual - EV Charging Station

Make sure EV charger autostart is disabled in general settings. This prevents the charging station from starting to charge automatically once it is connected to an EV.

Also ensure the Lock charger display setting on the general tab of the web interface or in the Remote console of the GX device is enabled.

Charging can then only be started or stopped via the web interface, VRM App widget, VRM controls and VictronConnect.

No. To prevent the charging station from being used by unauthorised persons, see Q1.

You can completely disable the light ring in the light ring menu, changing the brightness to 0 or a lower level if you like.

Try calibrating the CP line (general tab in the web interface or in the VictronConnect settings). This is sometimes necessary because the charging cables can differ slightly. Ground impedance is also important as all measurements are relative to ground (GND).

If there are several GX devices on the same local network, activate the IP address whitelist in the General tab of the web interface and then add only the IP address of the GX device with which the EVCS is to be controlled to the whitelist. After doing this, remove the EVCS from the other GX devices.

The minimum current for charging an EV is 6A@230V. You therefore need more than 1.3kW of PV.

However, if there is not enough excess solar power available to meet the minimum charge current requirement, it is possible to enable the 'Allow low excess solar power for auto mode' option. This option supplements the required power with additional power from the grid to meet the minimum current requirement. See chapter EV Charging Station setup web interface for details.

Example: To charge the EV at 6A while there is only 800W of excess solar power, 580W will be drawn from the grid to reach the required 1380W.

Note that there are EVs that require an even higher minimum charging current, e.g. the Renault Zoe; 10A.

Yes, this is possible. The available power is then shared between them.

The reason is most likely that the EVCS cannot correctly decode the 'charged' signal coming from the EV. Perform the CP line calibration to remedy the problem.

This error indicates that the EVCS cannot read the SoC from the GX device because there is a communication problem even though communication with the GX device is enabled in the EVCS web interface.

To remedy the problem, make sure that the IP address specified in the general settings of the web interface matches that of the GX device. Use the Discover function to allow the EVCS to derive the correct IP address from the VRM Portal ID - for more details, see the EV Charging Station setup chapter. Also make sure that ModbusTCP is enabled in the GX device itself.

This depends on the operation mode.

For automatic mode, communication between a GX device and the EVCS is mandatory. For manual and scheduled mode, a GX device can be installed, but does not have to be.

Yes, this is possible. Modbus TCP offers a much higher degree of flexibility and control and provides access to a broader range of settings than what is described in the manual or available through the normal user interfaces.

The recommended method for support on Modbus-TCP questions is to use the Modifications section on Victron Community. Its frequently visited by many people using Modbus TCP and other methods of integrating with Victron products.

The EVCS Modbus TCP register list can be downloaded from the product page in the download area.
