The maximum possible charging power must then be defined for each wallbox.
If your wallbox reaches the maximum charging current, the charging power is no longer increased. A wallbox with 11 kW can charge with a maximum of 16 A, a 22 kW wallbox with 32 A per phase.
Please also check the box if the connected car is a Renault. This is because these cars require at least 8 amps.
đź“Ś Note on charging current
Please make sure that the settings match your car and your wallbox. Control signals that are not accepted by one of the two can lead to problems with the control.
Possible example: Only a few cars today can charge with more than 16 A. If your car can only charge with 16 A, please do not set a higher charging current for the wallbox, as this will lead to errors in the power calculation.
Set charging mode
Finally, you must select which charging mode you prefer.
Low grid consumption: This mode is designed to have as little grid consumption as possible. If the PV surplus is no longer sufficient, the charging process is stopped after less than one minute.
Low feed-in: In this mode, if there are fluctuations in consumption or production, charging from the grid continues for several minutes before the charging process is stopped. If the surplus increases again, the charging process is continued. This maximizes self-consumption.
To customize our charging control to your personal needs, you can change the following parameters in the advanced wallbox menu after setting up the wallbox:
Â
Charging power
Several options are available for controlling the charging power:
Manually adjust charging power in amperes
Create SoC plan (see instructions)
Target charging (charge additional kWh up to a defined time)
Boost (charge with maximum power)
Â
Device name
The name of your wallbox is freely selectable.
Â
Min-Max charging current
Here you enter the minimum charging current your car should or can charge with.
Â
Phases
Here you can set how many phases your car should be charged with. Depending on the vehicle type, charging is possible with 1, 2 or 3 phases. For wallboxes with phase switching, we offer an automatic function that switches between 1 and 3 phases depending on the solar yield. Please check beforehand whether your car and your wallbox support phase switching. If you use phase switching, the charging process will be stopped before phase switching.
Â
A wallbox is usually connected with 3 phases. However, it makes sense to only charge with one phase for smaller PV systems. The lowest charging power with 3 phases and 6 A is approx. 4100 W, with one phase and 6 A only approx. 1400 W.
With 3 phases, charging only starts when at least 4100 W of surplus solar power is available; with one phase, approx. 1400 W is sufficient.
For single-phase charging, you only need to connect your wallbox to one phase or use a single-phase charging cable. If you have a wallbox with phase switching, such as the easee Home or the latest go-eCharger, you do not need this precaution.
Â
Please note that it is not sufficient to select the setting for charging on one phase if the car can charge on 3 phases and the wallbox cannot switch and is connected via 3 phases. In this case, we cannot switch to 1 phase.
Â
Charging mode
You can choose between 3 charging modes.
Clever mode: This mode is designed to use as little mains power as possible. In Clever mode, the charging process is stopped after less than one minute of mains supply.
Casual mode: “Casual mode” is designed to maximize self-consumption. In the event of fluctuations in consumption or production, charging from the grid continues for several minutes before the charging process is stopped. If the surplus increases again, the charging process is continued.
Always charging: In “Always charging” mode, the charging process is never stopped and charging continues at the minimum charging current. This mode is particularly suitable for cars that do not restart the charging process after a charging interruption.
Switching delay
The switching delay allows you to set the pause times between 2 switching operations. Hystereses are already stored, which are based on the manufacturer's specifications and what is technically feasible. You can set the minimum running time and the restart delay yourself.
If the solar share is set to 70 %, up to 30 % of the minimum power is drawn from the grid or, if available, from your home storage system. If your PV surplus then increases, the grid share is automatically reduced until no more electricity is charged from the grid.
If you operate a home storage system, which we can display, you can set a minimum SoC that should not be undercut. If the minimum SoC is not reached, the charging process will be terminated, except in the “always charging” charging mode, where we will continue the charging process beyond this.
If smart battery control is activated, charging will also automatically continue below the set minimum SoC, provided that the minimum battery charging capacity is exceeded.
Manual charging
It is also possible to charge your car manually. You can use this whenever you want to control the charging process yourself. You can simply set the charging power using the slider - to “Off” and “On”.
