Еlectric car charger Fronius Wattpilot 11j GO 11kW

Designed to move

The Fronius Wattpilot is the electric car charger. Not only can it be connected to your own PV system to charge your vehicle with your self-generated solar power. >The charger can be operated with ease via the Solar.wattpilot app, which also allows you to choose between Eco and Next Trip mode.

Can I switch charging mode in the Solar.wattpilot app?

You can change the charging mode either using the app or a button on the device.

 
Which models of car have limitations in terms of cost-optimized charging?

As it stands, there is still no standard for intelligent charging. For this reason, there may be limitations with cost-optimized charging for certain models of car. Fronius endeavours to configure the optimal charging behaviour for every vehicle.The following models of car are affected:

    Renault Zoe
    Twingo
    Kia e-Soul
    Mitsubishi i-MiEV
    Citroen C-Zero
    Peugeot iOn
    VW ID.3 / ID.4  (Due to the charging behaviour, charging must not be interrupted)

The selection of the car model can be found in the Solar.wattpilot app in Settings - Cost optimisation - Car.

 
Can the Wattpilot be used to charge my vehicle to a specific state of charge as a %?

No, it is not possible to do this. However, you can set it to charge to a specific power level in kWh or km, and the electric car will then be charged to this level within a defined time period.

 
What functionalities can also be used without the Wattpilot having an existing network connection?

All settings can also be set locally, directly by connecting to the Wattpilot’s hot spot. This is permanently open and secured with a password.The following functions are not possible without a network connection:

    Remote app access via the internet
    Coupling with the PV system (PV-optimised charging)
    Use of flexible electricity tariffs
    Software updates

Can the battery of the electric car also be discharged using the Wattpilot (vehicle to grid)?

No, this is not possible with the Fronius Wattpilot.

 
Can the Wattpilot also be visualized in Fronius Solar.web?

The visualisation for the Wattpilot can be shown directly in the Solar.wattpilot app. Alternatively, a secondary Fronius Smart Meter can be integrated in the Wattpilot load profile so that the data can be visualised in Solar.web.

 

How does energy management work when there is a battery and Ohmpilot in the overall system?

It is possible to combine the Wattpilot with Fronius-compatible DC-coupled battery storage units and the Fronius Ohmpilot. Threshold values can be defined for both the battery (state of charge in %) and the Ohmpilot (temperature in °C). As soon as the threshold values are reached, the current power values of the battery and Ohmpilot are considered as surplus. This means that the presence of a battery or Ohmpilot can also be taken into account within the system. Prioritization of the Wattpilot is possible, plus further prioritization of the Ohmpilot and battery can be carried out in the web interface of the inverter.

 
Can PV optimization/charging with variable energy tariffs also be used with multiple devices?

PV optimisation can only ever be used by one Wattpilot at a time. However, several Wattpilot charging solutions can be operated at staggered intervals. A variable electricity tariff can be used for multiple devices at the same time.

 
Can PV optimization/variable energy tariff be activated individually for the two charging modes?

Of course! PV optimization/use of the variable energy tariff can be activated or deactivated with ease in the app. Thus, a user without a PV system can also use the variable energy tariffs. Conversely, a user with a PV system can use the charging modes without a variable energy tariff. Of course, both options can also be used simultaneously.

Can the 1/3 phase power level, the value at which the Wattpilot switches from 1-phase charging to 3-phase charging, be self-defined?

Yes, this is possible! You can define this value yourself in the app. Thus the maximum negative phase sequence current for the Wattpilot can also be defined.

 
Can PV optimisation also be used with existing third-party inverters?

Yes, PV optimisation can also be implemented with non-Fronius inverters. However, these must be combined with a Datamanager Box 2.0 and a Fronius Smart Meter at the feed-in point. Apart from that, no further energy management (battery, Power2Heat, etc.) may be implemented at the same time, as the control systems can cause faults. The loads in the household are not included in the display in the Solar.wattpilot app.

 
How does PV optimization and 1/3-phase switchover control work?

PV optimization takes place in individual ampere steps and is specified by the type 2 standard. Therefore, charging steps in approx. 230 Watt (1-phase) or approx. 690 Watt (3-phase) are possible. The advantage of this is that it allows for optimum use of the PV system’s power range (charging power of 1.38 kW - 22 kW). The switchover works for vehicles which have 3-phase or 2-phase on-board chargers.

 
Are there ongoing software updates for the Wattpilot?

Yes, there will be ongoing software updates for the Wattpilot. These updates can be easily installed if the Wattpilot is connected to the Internet.

 
Can all cars handle a charging interruption, for example if cost-optimized charging is interrupted?

Several cars, such as Renault Zoe or Kia e-Soul models, do not start charging automatically after a charging interruption. The Wattpilot offers a “Simulate unplugging” function for this. The device ensures that charging continues by simulating disconnection of the car from the Wattpilot.

Can an ID chip be used for more than one Wattpilot?

Yes, this is possible. The ID chip must be specifically taught-in for each Wattpilot.

 
Is there a minimum charging time during which the Wattpilot does not switch off? For example, if the PV surplus is too low?

The Wattpilot charges for at least 5 minutes to protect the relays.

 
Which amperage is used for charging if the price level of the variable energy tariff falls below the selected limit value?

The set amperage is used for charging. There is no need to re-limit the current.

 
Does the Wattpilot have a digital bidirectional interface?

Yes, the Wattpilot can be controlled via the interface using the Solar.wattpilot app. This interface is encrypted for security reasons and also not made openly available.
