General Intended use The Fronius Wattpilot Flex Home 11 C6 / Home 22 C6 / Pro 11 C6E / Pro 22 C6E is a permanently mounted charging station for charging electric vehicles for fixed connection to an AC/three-phase network. The Wattpilot may only be used for the purpose of charging battery-powered electric vehicles and plug-in hybrid vehicles.
Suitable invert- Compatibility with the connected devices (see list below), suitable data commu- nication, and a Fronius Smart Meter at the feed-in point are prerequisites for us- ing certain Wattpilot functions (e.g., PV surplus). Suitable Fronius inverters Fronius GEN24 Fronius Tauro...
Keys and symbols Product over- view Rating plate position LED status indicator Card reader Operating mode buttons kWh display: Session kWh, Total kWh, Power kWh Mounting bracket Type 2 charging cable Card reader Behind the symbol is the card reader for reading ID chips and the reset card. The card reader uses RFID (radio-frequency identification).
Display Operating mode Standard mode The Wattpilot is in Standard mode. The indicator lights up white. The indicator flashes orange (see chapter Status codes on page 72). The indicator flashes red (see chapter Status codes on page 72). Eco Mode The Wattpilot is in Eco Mode.

Meaning Ready The Wattpilot is ready for operation. The more LEDs light up, the higher the set charging current. A few blue LEDs light up = low charging current (e.g. 8 A). Several/all blue LEDs light up = high charging cur- rent (e.g.
Page 17
Meaning Charging The LEDs indicate the energy sources. Non-illuminated LEDs run in a circle and indicate charging. Either 1- phase or 3-phase. Yellow LEDs = energy from PV surplus Green LEDs = energy from the battery White LEDs = energy from the grid Charging plug not plugged in The LEDs indicate the energy sources.

Meaning Earthing test deactivated The earthing test is deactivated. LEDs light up at the top, bottom, left, and right. Internal communication fault The Wattpilot displays an internal communication error. The error code is displayed in the app. For more informa- tion, see Status codes on page 72.
Meaning Charge controller error The charge controller is not working properly. For more information, see Status codes on page 72. The LEDs light up red at the bottom and yellow at the top for 1 second. Update The Wattpilot firmware is being updated. The update can take several minutes.

The ID chip is used for authentication and for recording user-specific charging amounts. In the app settings, authentication for charging can be activated under "Access management"...
26). Phase The Fronius Wattpilot can automatically switch between 1‑phase and 3‑phase changeover charging. The automatic phase changeover enables charging with a low start-up power (1‑phase with 1.38 kWh) in the case of a PV surplus. In addition, 1‑phase charging has the advantage that the charging power can be regulated in smaller increments (0.23 kW) and a small PV surplus can be used more efficiently.
Page 22
The settings for the start-up power level and 3‑phase power level can be made under Cost optimization in the Fronius Solar.wattpilot app. The power level can only be regulated in increments of 1 ampere. The table be- low lists the charging current in amperes (A) and the corresponding charging power for 1‑phase and 3‑phase charging in kilowatts (kW).
Page 23
This results in a power mix of self-consumption and grid supply. ▶ A start-up power level below 1.38 kW results in a power mix. Charging with PV surplus can be activated and adjusted in the Fronius Solar.wat- tpilot app (see Cost optimization on page 53).
*SOC - State of Charge of the stationary battery **Fronius-compatible DC coupled battery IMPORTANT! The energy management with the digital outputs (I/Os) on the Fronius inverter must not be used for load management of the Wattpilot! The priorities of the loads are not clearly assigned.

Enable The Eco Mode can be configured under Cost optimization (see page53) and ac- tivated by pressing the operating mode button or via the Fronius Solar.wattpilot app. NOTE! The battery of the photovoltaic system is discharged first! If the system contains a stationary battery, when the electricity price falls be- low the threshold, the battery of the photovoltaic system is discharged first in order to charge an electric vehicle before grid current is drawn.
In the Fronius Solar.wattpilot app, the PV surplus and/or flexible electricity tariff must be activated and set under cost optimization.

The daily journey to work and back home is 50 km and must start at 08:00 hrs. In the Fronius Solar.wattpilot app, the kilometers and the departure time must be entered once under Next Trip Mode. 18 kWh is used as the basis for the calcula- tion of 100 km.
To use Dynamic Load Balancing, either a Fronius inverter with Smart Meter, a Fronius Datamanager 2.0 with Smart Meter, or a Fronius Smart Meter IP must be installed in the complete system. In addition, the Wattpilot must be connec- ted to the Internet.
