Selecting phase usage
INFO
The menu item is only displayed if SW version 2021.51.9787 or higher is installed on the wallbox.
INFO
We would recommend updating an ENECTOR wallbox to version 2023.21.xxxx to make use of the automatic phase changeover function.
INFO
The electric vehicle may be damaged when changing over phase usage
The wallbox provides the option of changing phase during an active charging process.
Some vehicles on the market are not compatible with this type of phase change during an active charging process, so, in exceptional cases, this automatic changeover may lead to significant damage in the vehicle during charging.
Please check with your car manufacturer whether your vehicle supports this function. If it doesn’t, please first disconnect the vehicle from the wallbox before allowing the phase to be changed over.
Select the maximum number of phases with which you want to charge your electric vehicle.
When the phase is changed over while the charging plug is plugged into the vehicle, the charging process is always terminated before the phase is changed over. The charging process is interrupted for approximately 3 minutes.
- Standard (three-phase)
The three-phase electric vehicle can be charged with a power of between 4.1 - 11 kW. However, you can use this setting to charge all electric vehicles, no matter whether you want single-phase, two-phase or three-phase. The electric vehicle determines the maximum charging power. - Single-phase
The electric vehicle can be charged with a power of between 1.4 - 3.7 kW.
For three-phase electric vehicles, here you can change the number of phases for charging from three-phase to single-phase charging, which reduces the charging power to 1.4-3.7 kW. This is a good idea if you want to use Solar Pure Mode, for example, and do not have sufficient solar energy available (e.g. during spring or autumn). In this case, the vehicle can be charged with pure solar energy as of a surplus of 1.4 kW. - Automatic
During an automatic phase changeover, the wallbox automatically changes between 1-phase (1.4 - 3.7kW) and 3-phase (4.1 - 11kW) charging. The entire charging bandwidth of 1.4 kW to 11 kW is then available to charge the electric vehicle. In Solar Pure charging mode, this means that a single-phase charging process can be started when there is surplus PV power of between 1.4 and 4.2 kW. If the surplus PV power increases to above 4.6 kW during the charging process, charging is automatically changed over to three-phase. Whenever the system changes phase, the active charging process is always first interrupted and then restarted with the new phase setting.
The automatic phase change process:
At the start of charging, the system checks whether the PV surplus is sufficient for 3-phase charging. If it is, the charging process is started in 3-phase. If the PV surplus isn’t sufficient, charging starts in 1-phase. Every 15 minutes, the system checks whether it is able to switch to 3-phase charging. If it is, the change is made. For this to happen, the charging current available must be 7% above the minimum charging current for 3-phase charging. If 3-phase charging is no longer possible because the PV power is no longer sufficient, due e.g. to cloud formation, after a period of 5 minutes the system attempts to switch to 1-phase charging. If the surplus power needed for this is also no longer sufficient, charging is paused.
