The Wattpilot Flex is equipped with ISO15118 communication hardware, which is a basic requirement for bidirectional charging. However, there are further requirements for bidirectional charging:

1. The electric vehicle must support bidirectional charging. There are already several vehicles on the market that support bidirectional charging when used with a compatible wallbox. However, this is often not ideal for end users, as the wallbox may become incompatible in the case of a vehicle replacement. In most cases, the system offers a backup power supply, but no grid-connected function that can be used to supply the house with the vehicle at night, for example.
   
   
2. If energy is fed from the electric vehicle back into the house or even into the grid, the grid operator’s requirements must be met. In the case of an AC wallbox, the electric vehicle must support this functionality, which means that an electric vehicle must distinguish between different grid requirements depending on where it is currently connected.
   
   Put simply, although the Wattpilot Flex is equipped with ISO15118 hardware, it does not currently support bidirectional applications. It is not possible to discharge the vehicle battery into the house or grid (vehicle-to-grid).
   
   Note: Pay close attention to this with wallboxes from other manufacturers, as the ISO15118 hardware is often incorrectly equated with bidirectional charging.

When the device connects to an inverter (automatically or manually via the Solar.wattpilot app), it is automatically added to the associated PV system in Solar.web. Alternatively, you can add the device manually at any time:

• In your PV system in Solar.web under Settings > Components
•  If no PV system is available, register at www.solarweb.com and add the device and the paired inverter when creating the system.

We recommend that the device is online and paired with the inverter when it is added. An offline device can also be added, but data is only displayed when it is online and paired.

The Wattpilot can be integrated into a network via WiFi. If the device is outside the WiFi range, the signal can be extended using a repeater, WiFi access point, or PowerLine adapter.

The Wattpilot Flex can also be integrated via Ethernet (LAN), while the Wattpilot Home and Go only support WiFi.

All settings can also be made locally via the Wattpilot hotspot. This hotspot is permanently open and password-protected.

The following functions are not available without a network connection:

• Remote access via the app
• Pairing with the PV system (PV-optimized charging)
• Use of flexible electricity tariffs
• Dynamic Load Balancing
• Software updates

Yes, any number of Wattpilots can be operated in parallel. Each Wattpilot must be individually integrated into the network. However, PV optimization only works for one device at a time.

Prioritization between several Wattpilots is possible. If the set priorities are the same, the priorities are as follows:

• Priority 1: Standard Mode
• Priority 2: Next Trip Mode
• Priority 3: Eco Mode

If the charging mode is the same, the current will be divided equally.
The Wattpilot charging boxes can also be added to a PV system in Solar.web for joint visualization.

Yes, that is possible. The Wattpilot Flex Pro is MID-compliant and fulfills the measurement and calibration law so that the charged energy can be billed to third parties.

All Wattpilot charging boxes also offer OCPP 1.6J and an RFID reader. This allows the amount of energy charged in kWh and the charging time per RFID chip to be recorded for each charging process. The data can be exported as a CSV file, which also allows billing according to charging time (in minutes).

Yes, the Wattpilot can be controlled via the interface using the Solar.wattpilot app. For security reasons, this interface is encrypted and not made public.

The Wattpilot also offers OCPP 1.6J as an open interface for integration into external systems.

Next Trip Mode ensures that your vehicle is sufficiently charged for your next trip. A certain amount of energy in kWh or kilometers can be specified, which is charged up to a defined point in time.

A direct state of charge as a percentage cannot be set.

PV surplus charging can be activated in the Solar.wattpilot app.

Optimization takes place in individual ampere increments, as specified by the type 2 standard. This enables charging increments of approx. 230 watts (1-phase) or approx. 690 watts (3-phase). This makes optimum use of the PV system’s power range, with a charging power of 1.38 kW to 22 kW. Switching between 1-phase and 3-phase charging works for vehicles with a 2-phase or 3-phase onboard charger.

The value for switching between 1-phase and 3-phase charging can be set individually in the app.

A Fronius inverter with Fronius Smart Meter at the feed-in point is required for PV optimization. Compatible inverters are GEN24, Verto, SnapINverter from Datamanager 2.0 and IG, IG Plus, IG TL and CL series in combination with a Datamanager 2.0. The combination with a Fronius Ohmpilot and a Fronius-compatible DC-coupled battery is also possible.

PV optimization can also be used with third-party inverters if they are combined with a Fronius Smart Meter IP or a Datamanager Box 2.0 and a Fronius Smart Meter at the feed-in point. However, no other self-consumption regulations (e.g., battery, Power2Heat) may be active in parallel, as the controls may interfere with each other. In addition, household loads are not taken into account in the app.

PV optimization can only be used with one Wattpilot at a time. However, several Wattpilots can be operated at staggered intervals.

Dynamic Load Balancing is activated and configured in the Solar.wattpilot app. You can also make advanced settings there, such as limiting the maximum current carrying capacity of the supply line.

There is no limit to the number of Wattpilot charging boxes that can be operated with Dynamic Load Balancing.

The following components are required for use:

• Fronius Smart Meter IP or
• a compatible Fronius inverter with Fronius Smart Meter or
• a Datamanager Box 2.0 with Fronius Smart Meter at the feed-in point.

The maximum current carrying capacity of the supply line can also be set. This option can be found in the app under Settings → Load Balancing → Dynamic Load Balancing. It is required if the supply line can handle a lower current than the sum of the connected Wattpilots. This prevents the automatic circuit breaker from overloading and tripping.

A combination with the Fronius-compatible DC-coupled battery storage systems and the Fronius Ohmpilot is possible. Both the threshold values for the battery (state of charge as a %) and for the Ohmpilot (temperature in °C) can be defined in the app. As soon as these values are reached, the current power values of the battery and Ohmpilot are considered as surplus.

This means that the battery and Ohmpilot can be taken into account in the system. Prioritization of the Wattpilot is possible. In addition, further prioritization between the Ohmpilot and battery can be defined on the user interface of the inverter.

Hotspot password: The password is on the reset card supplied. If you have changed the hot spot password, this can be reassigned via the Solar.wattpilot app under Settings > Password or reset to the factory settings with a long tap on the Wattpilot Home/Go. If the reset card is misplaced, it can be reordered from Fronius with proof of purchase.

Wattpilot password: Connect to the Wattpilot via the hotspot, restart the Setup wizard and assign a new password.

Technician password: Please contact technical support via our contact form. The serial number, purchase invoice and a picture of the rating plate are required.

The installer of the system should create a service case for the affected device on Fronius Solar.SOS. Please include the following information:

• Serial number
• Purchase invoice
• Photo of the rating plate

• Check the Phase Switch setting in the Solar.wattpilot app under Settings > Car.
• Make sure that your charging cable and the charger in your car support three-phase charging and that the Wattpilot is supplied with 3-phase power.
• Check the car’s app to see if there are settings restricting single-phase charging.

Network:

Update your components to the latest firmware version.

For GEN24 inverters with firmware version 1.14.110-1 or higher, ensure that the Solar API is activated in the user interface of the inverter under Communication > Solar API. Also make sure that your inverter and your Wattpilot are in the same IP network, especially if you are using subnets.

Inverters:

Check the WiFi signal strength of your network on your Wattpilot. For a stable connection, the Solar.wattpilot app should recognize your WiFi with at least 50% strength.

Ensure the following so that data is displayed:

• Add devices: Wattpilot and inverters must be added to your PV system in Solar.web under Settings > Components. If this tab is not visible, ask your installer to assign you owner or supervisor permissions.
• Internet connection: Both devices must be online.
• Wattpilot firmware: Version 36.0 or higher. Update in the Solar.wattpilot app under Internet.
• Pairing: Wattpilot must be connected to WiFi and paired with the inverter. This is done in the app under Settings > Cost Optimization.
• Inverter firmware: For GEN24, Verto or Tauro at least version 1.30. Update in Solar.web under Settings > Components.

No live or historical data is displayed for periods without an Internet connection (e.g., when WiFi is weak). This data is not subsequently restored.

Data is also only displayed if the Wattpilot is paired with an inverter that is located in the same PV system in Solar.web. If the Wattpilot Go is used on the move, no data will appear for these periods.

The device is not added automatically if one of the following applies:

• It is connected to the wrong inverter
• It is connected to a GEN24, Verto or Tauro inverter and: 
  - Wattpilot firmware < 36.0
  - Inverter firmware < 1.30

Solution: Update the firmware and add the device manually in Solar.web.
