1. General information

The Wattpilot can be used like any other charging station. For start-up, the charging cable must be plugged in and the Wattpilot starts charging. By pressing the pushbutton (see Pushbutton functions on page (→)) it is possible to switch between the charging modes (see Different charging modes on page (→)) and change the level of charging current (see Current level on page (→)).

1. General information
2. Functions

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 (→)).

1. General information
2. Functions

Compliance with the phase unbalanced load limits is required by law in certain countries, for example in Austria and Germany.

Unbalanced load management limits the total charging current, which means that the unbalanced load is below the desired value. It is important to comply with the phase unbalanced load limits in order to protect the grid, make charging electric vehicles efficient, and comply with the applicable regulations.

The maximum phase unbalanced load can be set by a qualified electrician in accordance with the applicable regulations (see Grid settings on page (→)).

1. General information
2. Functions

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 (→)).

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.

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 optimization 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

Example

	Photovoltaic generation
	Electric vehicle

The figure illustrates the behavior 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 kW increments.
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 kW increments.

Charging with PV surplus can be activated and adjusted in the Fronius Solar.wattpilot app (see Cost optimization on page (→)).

Priorities in the system between battery, Ohmpilot, and Wattpilot

The priority of the Wattpilot can be influenced via the "PV battery threshold" and "Ohmpilot threshold" settings in the Fronius Solar.wattpilot app (see chapter Cost optimization on page (→)). 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.

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.

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.

1. General information
2. Functions

Tariff zones
If you are a customer of a flexible electricity tariff retailer, you can use the flexible electricity tariff. This is taken into account when using Eco Mode and Next Trip Mode.

Retailer
The flexible electricity tariff can be used if electricity is purchased from electricity retailers and charged for hourly via the electricity exchange, e.g.,

• Lumina Strom hourly
• aWattar hourly
• Tibber

The Wattpilot queries the various retailer tariffs from the electricity exchange directly via the Internet. It is possible to specify a price threshold (Eco Mode price limit) below which charging starts.

IMPORTANT!
The prices displayed show the current tariffs of the electricity exchange; depending on the retailer, additional costs may apply.

Example
The following figure shows the electricity price of an electricity retailer over 24 hours. The hourly tariffs are retrieved from the electricity exchange at a specific time for the next day.

1. General information
2. Functions

Prerequisite
To be able to use Boost Mode, there must be a stationary battery storage system in the PV system and Eco or Next Trip Mode must be selected.

Function
Activating the Boost uses the energy for charging directly from the stationary battery storage system. As a result, low-cost energy can be obtained, even if no PV surplus is available. In the Boost settings, it is possible to set how much residual energy (SOC) should remain in the stationary battery. In addition, you can set whether the charge from the stationary battery should be used once, or for as long as the vehicle is plugged in.

When Boost is activated, it can take up to 10 minutes for the battery to discharge at maximum power. If the inverter has already reached the maximum total power (through PV) or the battery cannot be discharged, the Wattpilot still charges with at least 1.4 kW. The minimum SOC of the battery at the inverter must be greater than the "Discharge until" limit value.

Example
Let's imagine that your stationary battery storage system is 80% charged. Due to the current weather conditions, no additional energy is stored. If you now activate the Boost, the stored energy will be transferred to your vehicle. Note that the discharging limit of the stationary battery is taken into account (e.g., 20% set = 20% of the energy always remains in the stationary battery storage system). Activating Boost also means that the discharge is continued as long as the vehicle is connected. If the weather conditions change and the PV surplus is fed into the stationary battery storage system again, your vehicle will continue to be charged until it is unplugged. A residual amount of energy of 20% is always retained in the stationary battery storage system.

1. General information

In standard mode, charging takes place at the preset amperage (e.g., 16 A). The level of charging current can be changed by pressing the pushbutton on the Wattpilot. In the app (see Current level on page (→)), the charging current can be adjusted in 1 ampere increments.

In standard mode, no operating mode LEDs light up.

Whereas charging at a low charging current is gentle, charging at a high charging current enables rapid charging. If necessary, charging is carried out with electricity sourced from the grid.

2. Different charging modes

In standard mode, charging takes place at the preset amperage (e.g., 16 A). The level of charging current can be changed by pressing the pushbutton on the Wattpilot. In the app (see Current level on page (→)), the charging current can be adjusted in 1 ampere increments.

In standard mode, no operating mode LEDs light up.

Whereas charging at a low charging current is gentle, charging at a high charging current enables rapid charging. If necessary, charging is carried out with electricity sourced from the grid.

1. General information
2. Different charging modes

In Eco Mode, a vehicle is only charged when low-cost electricity is available. Charging can either take place with cheaply purchased electricity (see Flexible electricity tariff on page (→)) or surplus energy produced by the photovoltaic system (see PV surplus on page (→)). There is no guarantee that charging will occur.

Prerequisite
Charging in Eco Mode is only possible if PV surplus and/or a Flexible electricity tariff is activated under PV surplus in the Fronius Solar.wattpilot app.

Enable
Eco Mode can be configured in the app under Cost optimization on page (→) and activated by pressing the pushbutton (< 0.5 s) or via the Fronius Solar.wattpilot app.

Example

	Photovoltaic generation
	Electric vehicle
	Household consumption

In Eco Mode, the electric vehicle is connected to the Wattpilot at around 3 p.m., as although a fixed additional range for the electric vehicle is not necessary, cheaper electricity is to be used for charging. In the Fronius Solar.wattpilot app, the PV surplus and/or flexible electricity tariff must be activated and set under Cost optimization. Household consumption is covered by photovoltaic generation and the electric vehicle is charged with the PV surplus. Charging takes place using the PV surplus until around 8 p.m. Between 2 a.m. and 5 a.m., the electricity price falls below the defined price limit. The electric vehicle is charged with cheap electricity during this period.

Charging in Eco Mode

1. General information
2. Different charging modes

In Next Trip Mode, a vehicle is charged as cheaply as possible until the end of the self-selected time with the set charging amount. The time charging starts is selected in such a way that the desired charging amount is charged at least one hour before the charge end. Charging takes place in the cheapest cost window. The PV surplus and flexible electricity tariff settings are taken into account. If the "Stay in Eco Mode" function (for activation see Next Trip Mode on page (→)) is activated, the Wattpilot continues charging with low-cost energy after the set charging amount has been reached.

The set charging amount is charged in addition to the charging amount available in the electric vehicle. The charging amount is specified in kilometers and calculated on the basis of an average consumption (18 kWh/100 km). External conditions (season, driving speed, vehicle model, etc.) may cause deviations in the actual range. When setting the charging amount, the actual state of charge of the electric vehicle battery is not read out.

The mode can be set under "Next Trip Mode" in the Fronius Solar.wattpilot app (see Next Trip Mode on page (→)).

After activating the mode, charging is started briefly to calculate a charging schedule taking into account the possible charging power. If no flexible electricity tariff is activated, charging is started at the latest possible time in order to charge with a possible PV surplus and to conserve the battery of the electric vehicle. If no time is provided for the calculation of the charging schedule, charging starts immediately.

If the charging cable is disconnected and reconnected while Next Trip Mode is activated, the calculation is repeated and the set charging amount is charged in addition to the existing charging amount. Changes to the settings of the Fronius Solar.wattpilot app result in a recalculation of the charging schedule. If the change is made during Next Trip Mode charging, the range charged up to this point is added to this.

If "Stay in Eco Mode" is activated, the cost optimization settings are also taken into account in Next Trip Mode.

Example

	Photovoltaic generation
	Electric vehicle
	Household consumption

The daily journey to work and back home is 50 km and must start at 8 a.m. 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 calculation of 100 km. The electric vehicle is plugged in and charged at approximately 3 p.m. If PV surplus is available, charging is carried out with PV surplus. The remaining charging amount is guaranteed to be charged in the electric vehicle at the latest possible time. The charge is calculated in such a way that it is completed at the latest one hour before departure.

1. General information

Wattpilot supports dynamic load management, known as Dynamic Load Balancing. 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 connected to the Internet. The settings implemented can be protected with a technician password (see Password on page (→)).

Dynamic Load Balancing distributes power while charging with several Wattpilots, depending on their prioritization. The power is distributed dynamically taking into account PV surplus and the maximum reference current in the system. The prioritized vehicles are charged first.

1. General information
2. Dynamic load balancing

Wattpilot supports dynamic load management, known as Dynamic Load Balancing. 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 connected to the Internet. The settings implemented can be protected with a technician password (see Password on page (→)).

Dynamic Load Balancing distributes power while charging with several Wattpilots, depending on their prioritization. The power is distributed dynamically taking into account PV surplus and the maximum reference current in the system. The prioritized vehicles are charged first.

1. General information
2. Dynamic load balancing

With Dynamic Load Balancing, the maximum reference current can be defined for the house connection point (feed-in point). The energy produced by the photovoltaic system and the loads are automatically taken into account. Up to 3 Wattpilots can be dynamically controlled. This dynamic control ensures the maximum possible charging current can be used.

Dynamic Load Balancing monitors the available current per phase (including solar power) at the house connection point (feed-in point) and dynamically distributes this to one or more Wattpilots. In this case, the Wattpilots can be supplied with the maximum available current; the maximum current is not exceeded. In addition, the current (reference current) for the Wattpilots can be limited.

The maximum reference current must be set to match the post-meter fuse.

Control system example

(1)	Photovoltaic system
(2)	Inverter
(3)	Loads (e.g., TV, washing machine, light)
(4)	Smart Meter
(5)	Fronius Wattpilot
(6)	Electric vehicle
(7)	Grid

In the example of a control system, 32 A are drawn from the public grid and 8 A are generated by the PV system, for a total of 40 A of available electricity. The household loads require 20 A, and the remaining 20 A are dynamically divided among the connected Wattpilots to enable charging of, for example, two electric vehicles with 10 A each.

1. General information
2. Dynamic load balancing

In the case of systems with multiple Wattpilots, charging priorities can be set. The charging stations (electric vehicles) with a higher priority are supplied with current first; charging stations with a lower priority have to wait. If there is current left over, it is shared among the lower-priority Wattpilots.

The vehicles that are to be charged first and with the maximum available current must be assigned a high priority. A low priority can be assigned to vehicles that should wait to charge until sufficient current is available.

In the case of Wattpilots with the same priority, the available current is shared equally.

Example 1

Distribution of the charging current with three Wattpilots with different priorities (one with high priority, two with medium priority).

Example 2

Distribution of the charging current with three Wattpilots (X, Y, Z) with the same priority. Each Wattpilot is assigned the minimum charging current (unless the minimum charging current is no longer available). If there is charging current left over, it is distributed wherever possible, starting with the first Wattpilot in the loop.

Wattpilot X has a minimum charging current of 6 A, Wattpilot Y 10 A, and Wattpilot Z 6 A. There is 15 A of charging current to be distributed. The charging current is distributed as follows.

1. X receives 6 A, 9 A remains.
2. Y receives nothing as the minimum charging current of Y is 10 A. Y is set to 0.
3. Z receives 6 A, 3 A remains.
4. The loop starts all over again.
5. X receives 7 A, 2 A remains.
6. Y receives nothing as the charging current has already been set to 0 in the first loop.
7. Z receives 7 A, 1 A remains.
8. The loop starts all over again.
9. X receives 8 A, 0 A remains.

The 15 A charging current was distributed among the equally prioritized Wattpilots and charged. As soon as charging current is available again, the electric vehicle is charged at Wattpilot Y.

2. Settings

Under "Cost optimization", the consideration of the electricity tariff (see Flexible electricity tariff on page (→)) and the use of PV surplus (see PV surplus on page (→)) can be activated. The settings listed below can also be customized.

Use flexible tariffs
Activate or deactivate, and select the corresponding country below. Either select the flexible electricity tariff of a retailer, if available, or select a tariff zone.

Eco Mode price limit
When a flexible electricity tariff is activated in Eco Mode, charging does not start until the set electricity price is below this value. If the electricity price is above this value, charging does not take place.

Use PV surplus
Activate or deactivate. If "Use PV surplus" is activated, the Wattpilot uses the surplus PV energy for charging.

Inverter
Selection of a coupled inverter.

PV battery threshold
If a battery is installed in the photovoltaic system, a limit value can be set here. Below the set value, the battery is charged as a priority. Above this value, the energy is charged into the vehicle instead of into the stationary battery. The SOC (state of charge) of the battery may still slowly increase.

Ohmpilot threshold—optional
If a Fronius Ohmpilot with a temperature sensor is installed in the photovoltaic system, a limit value for the temperature can be set here. Below the set value, the available energy is prioritized for heating. Above this value, the vehicle is charged instead of heating with the Ohmpilot. The temperature may still slowly increase.

PV surplus—advanced settings
In the advanced settings, a start-up power level can be set from which the PV energy is used for charging. Vehicles require a certain minimum power in order to charge.

• Start-up power level: If "0" is set, the Wattpilot will start charging even if no PV surplus is available.
• Zero feed-in: No PV current is fed into the grid. If zero feed-in is activated in the inverter, it must also be activated in the Wattpilot.

Deviations may occur when using PV surplus, as vehicles are regulated in stages. The following settings can be made under Control response:

• Prefer from grid: The Wattpilot prioritizes consumption over feed-in from the grid.
• Default: The Wattpilot enables both consumption and feed-in.
• Prefer to grid: The Wattpilot prioritizes feed-in over consumption from the grid.

Car—advanced settings
With intelligent charging, the charging process can be interrupted or the charging current reduced in order to meet certain charging conditions. Specify car-specific settings for smooth smart charging.

• Choose car: For activating the optimized standard settings of different vehicle models.
• Minimum current: Some cars will not resume charging after an interruption. To prevent an interruption, the minimum charging current can be set.
• Forced charging interval: In the case of cost-optimized charging, the Wattpilot interrupts the charging process if the electricity price is too high. Some cars will not tolerate interruptions and will not continue charging after prolonged interruptions to the charging process. In this case, the charging process must be started regularly for a short time.
• Allow charging pause:  Some cars will not resume charging after an interruption. Charging interruptions are prevented if this option is deactivated.
• Simulate unplugging: Some cars need to be disconnected for a while if there has been an interruption during cost-optimized charging. This function simulates a disconnection before charging continues.
• Charging pause: Some cars require a certain amount of time after an interruption to charging before they can start charging again.
• Minimum charging time: Set the minimum time for which the car must be charged after charging starts.
• Choose phase switch:
  • Automatic: A power level can be set, from which 3‑phase charging takes place. If "0" is set, the Wattpilot immediately starts 3‑phase charging.
  • Only 1 phase: There is 1 phase available for charging.
  • Only 3 phase: There are 3 phases available for charging.
• 3‑phase power level: Set a power level that must be reached by the photovoltaic system before the Wattpilot switches from 1‑phase to 3‑phase charging. If the available power is greater than the set value, the Wattpilot immediately activates 3‑phase charging. Automatic switching can be deactivated in the car settings.
• Phase switch delay: Phase switching is performed when the "3-phase power level" is permanently exceeded or undercut during this period.
• Phase switch interval: Minimum time between phase switching.

Dynamic load balancing

For general information on Dynamic load balancing, see Dynamic load balancing on page (→). Dynamic load balancing monitors the current at the reference point. It dynamically limits the current for up to three Wattpilots to ensure that the maximum reference current is not exceeded. The following settings can be made:

• Maximum reference current
  Set the maximum reference current for the power connection, which must not be exceeded.
• Max. current of supply line
  Limit the total current of all Wattpilots so that the mains lead is not overloaded.
• Phase assignment
  The Smart Meter monitors each phase. For load balancing to work properly, the phase assignment of the Wattpilot must be set in relation to the Smart Meter. This causes the correct Wattpilot to be regulated back when the current of a phase is exceeded.
• Priority
  In the case of systems with multiple Wattpilots, charging priorities can be set (see Priority).
• Fallback mode
  If there is no connection to the server, the Wattpilot limits the charging current back to the set value in fallback mode. This ensures that the infrastructure is not overloaded.
