ENECTOR with convenience functions via KOSTAL Smart Energy Meter

Blackout protection (house connection monitoring)
The house connection is monitored when charging the electric vehicle. If the maximum connected load (e.g. 63 A) is exceeded, the charging power is reduced or charging is interrupted.

Lock Mode (lock wallbox)
If a KOSTAL Smart Energy Meter (KSEM) is connected to the wallbox and the wallbox has been activated via an activation code in the KSEM, the wallbox can be locked via the KSEM. It can then only be unlocked by selecting another mode in the KSEM.

Power Mode (simple charging)
The electric vehicle is charged at maximum power.

Solar Pure Mode (solar charging)
Solar charging is only possible in combination with a PV system and the KOSTAL Smart Energy Meter. The PV system supplies the power needed to charge the electric vehicle.

The function is usually actively selected via the user interface of the KOSTAL Smart Energy Meter.

If an optional push-button (not included in the scope of delivery) has been fitted in the device, the push-button can be used to switch between all modes (except Lock Mode).

With this function, the electric vehicle is only charged using the PV surplus.

For electric vehicles that are charged 1-phase, the charging power is between 1.4 and 3.7 kW. This means that charging is only started when at least 1.4 kW of surplus PV energy is available and is interrupted or terminated when this falls below 1.4 kW.

For electric vehicles that are charged 3-phase, the charging power is between 4.1 and 11 kW. This means that charging is only started when at least 4.1 kW of surplus PV energy is available and is interrupted or terminated when this falls below 4.1 kW.

1	PV surplus
2	Max. wallbox charging power 3.7 kW (with 1-phase vehicle) Max. wallbox charging power 11 kW (with 3-phase vehicle)
3	Min. wallbox charging power 1.4 kW (with 1-phase vehicle) Min. wallbox charging power 4.1 kW (with 3-phase vehicle)
4	Charging electric vehicle with PV surplus
5	Electric vehicle charging time
6	Home consumption of other devices - partly covered directly from PV.

INFO

Hysteresis for passage of clouds (changing cloud cover): If the surplus needed to charge the vehicle is no longer available due to further consumers or the passage of clouds, charging is not interrupted immediately. Instead, it is reduced to the minimum charging power for approx. 5 min to avoid an interruption in charging after the vehicle has frequently switched charging on and off.

Solar Plus Mode (solar-optimised charging)
Solar-optimised charging is only possible in combination with a PV system and the KOSTAL Smart Energy Meter. The PV system supplies the energy needed to charge the electric vehicle.

The function is usually actively selected via the user interface of the KOSTAL Smart Energy Meter.

If an optional push-button (not included in the scope of delivery) has been fitted in the device, the push-button can be used to switch between all modes (except Lock Mode).
With this function, the charging power specified by the customer is made available to the vehicle for charging.

If there is a PV surplus at the grid interconnection point, the amount drawn from the grid is replaced by the PV power or, if possible, increased to the PV surplus.

If desired, a minimum PV surplus power can also be defined here. This is the minimum level which must be present before charging is started at the power level defined by the customer. If the surplus power falls below the defined minimum value, charging is stopped again.

This function can be used to charge the electric vehicle in the evening, for example, when there is no longer enough PV energy available but the electric vehicle needs to be charged for the next morning.

1	PV surplus This surplus can also be used to charge a battery.
2	Max. wallbox charging power 11 kW (3-phase).
3	Fixed minimum starting charging power In this example, at 50 % of the max. charging power of 11 kW (for 3-phase connection with 3-phase vehicle = 5.5 kW).
4	Set min. surplus power at the grid connection point before charging is started. In this example, 60 % of 5.5 kW = 3.3 kW. The additional charging power of 2.2 kW (5) is drawn from the public grid.
5	Charging electric vehicle from the public grid. In this example 2.2 kW.
6	Charging electric vehicle from PV surplus.
7	Electric vehicle charging time.
8	Home consumption of other devices - partly covered directly from PV.

INFO

Hysteresis for passage of clouds (changing cloud cover): If the surplus needed to charge the vehicle is no longer available due to further consumers or the passage of clouds, charging is not interrupted immediately. Instead, it is reduced to the minimum charging power for approx. 5 min to avoid an interruption in charging after the vehicle has frequently switched charging on and off.

Time Mode (time-controlled charging)

In this mode, you can define the time and the day of the week when one of the available modes is used.

For example, you can lock the wallbox during times when you are generally not present (e.g. between 8 am and midday) (Lock Mode) and switch to solar charging (Solar Pure Mode) during periods when you plan to be present.

If the vehicle is to be charged at a low power rating (Solar Plus Mode) at night or at full charging power (Power Mode), this can also be scheduled in.

INFO

When Time Mode is active, use of the external optional push-button is deactivated so that planned locked periods cannot be cancelled.

Phase usage

INFO

The menu item is only displayed if SW version 2021.51.9787 or higher is installed on the wallbox.

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 4.2 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 starts 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.
