Suitable inverters
The device has a built-in residual current protection module with residual current
detection (20 mA AC and 6 mA DC). This means that no upstream type B residual-current circuit breaker is required. A separate type A residual-current circuit
breaker and an automatic circuit breaker must be connected upstream for each
Wattpilot.
The device may only be operated at the following connections:
CEE red 32 A, 3-phase, 400 V
-
CEE red 16 A, 3-phase, 400 V
-
With original adapters:
-
CEE red 16 A, 3-phase, 400 V
-
CEE red 32 A, 3-phase, 400 V

Functions
Overview The Wattpilot can be used like any other charging station. For start-up, the char-
ging cable must be plugged in and the Wattpilot starts charging. By pressing the
pushbutton (see Pushbutton functions on page 15) it is possible to switch
between the charging modes (see Different charging modes on page 26) and
change the level of charging current (see Current level on page 53).
Phase
changeover
PV surplus
The Fronius Wattpilot can automatically switch between 1‑phase and 3‑phase
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. As
1‑phase charging is limited by the car, it makes sense to switch to 3‑phase charging at a higher PV surplus. This allows higher maximum charging outputs to be
achieved.
The phase changeover can be set automatically or manually (see PV surplus on
page 22).
NOTE!
Do not exceed the phase‑load imbalance!
Select the phase changeover point in such a way that the maximum permissible
phase‑load imbalance is not exceeded.
NOTE!
A minimum charging time of 5 minutes is stored.
To prevent permanent switching of the relays and to increase the service life of
the Wattpilot, a minimum charging time of 5 minutes is stored.
22
The surplus energy of a PV system (photovoltaic system) can be used. The prerequisites for this are a compatible inverter in the same network as the Wattpilot
and a Fronius Smart Meter (for more information, see Data communication with
the inverter on page 44).
Setting limit values ensures that the available PV surplus power is distributed to
the loads. The limit values created allow an energy storage system to be sufficiently charged or the energy to be stored in the form of hot water before the
surplus PV power is used to charge a vehicle.
NOTE!
PV surplus regulation.
One Wattpilot per photovoltaic system.
The PV surplus regulation works with one Wattpilot per photovoltaic system.
▶
If several Wattpilot devices are connected to one inverter, "Use PV surplus"
▶
may only be activated on one Wattpilot. For all other Wattpilot devices, "Use
PV surplus" must be deactivated (for more information, see Cost optimisa-
tion on page 53).
It is possible to set a start-up power level (specified in kilowatts/kW). This must
be reached by the photovoltaic system before the Wattpilot starts charging the
car with the minimum current.
It is possible to set a 3‑phase power level (specified in kW). This must be reached
by the photovoltaic system before the Wattpilot switches from 1‑phase to
3‑phase charging.
The settings for the start-up power level and 3‑phase power level can be made
under Cost optimisation in the Fronius Solar.wattpilot app.
The power level can only be regulated in increments of 1 ampere. The table below lists the charging current in amperes (A) and the corresponding charging
power for 1‑phase and 3‑phase charging in kilowatts (kW). 1-phase in 0.23 kW increments, 3-phase in 0.69 kW increments. The values are based on the assumption that the voltage is exactly 230 or 400 V.
Example: The charging current is increased by 1 A to 7 A.
-
1‑phase: 1.38 kW + 0.23 kW = 1.61 kW
-
3‑phase: 4.14 kW + 0.69 kW = 4.83 kW

Photovoltaic generation
Electric vehicle
The figure illustrates the behaviour of the Wattpilot with a set start-up power
level of 1.38 kW and a 3‑phase power level of 4.14 kW. If the PV surplus is less
than 1.38 kW, the vehicle is not charged.
If the PV surplus is between 1.38 and 4.14 kW, the Wattpilot regulates the charging power in 0.23 kWincrements.

If the PV surplus is above 4.14 kW, the Wattpilot switches from 1‑phase charging
to 3‑phase charging and regulates the charging power in 0.69 kWincrements.
NOTE!
The minimum charging power of electric vehicles is usually 1.38 kW.
In the case of smaller photovoltaic systems, it may make sense to set the startup power level below 1.38‑kW so that sufficient energy is charged. The electricity
that is not covered by the photovoltaic system, however, is drawn from the grid.
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.wattpilot app (see Cost optimisation on page 53).
Priorities in the system between battery, Ohmpilot and Wattpilot
The priority of the Wattpilot can be influenced via the "PV battery limit value"
and "Ohmpilot limit value" settings in the Fronius Solar.wattpilot app (see
chapter Cost optimisation on page 53). Depending on the level of the selected
limit values, it is possible to define under which conditions the charging of the
electric vehicle starts. The temperature limit value of the Ohmpilot can only be
used if a temperature sensor is connected to the Ohmpilot. To set the Wattpilot
priority, the energy management priority settings on the user interface of the inverter must also be taken into account.
NOTE!
If no temperature sensor is connected to the Fronius Ohmpilot, a temperature of
0 °C is assumed. If the Wattpilot is to be prioritised over the Ohmpilot, the
"Ohmpilot limit value" must be set to 0 °C. In the event of a sensor break, the
Ohmpilot is supplied with power before the Wattpilot.
Example: Charging the electric vehicle first
The electric vehicle must always be charged with PV surplus before the battery
and the Ohmpilot. In the Solar.wattpilot app, the limit value for the battery is
set to 0% and the limit value for the Ohmpilot is set to 0 degrees. The electric
vehicle is immediately charged with PV surplus, regardless of the state of
charge of the battery or the temperature of the Ohmpilot.
