IMPORTANT!

During operation, due to the high electrical voltages and currents, local electromagnetic fields (EMF) occur in the environment around the inverter and the Fronius system components as well as in the area of the PV modules including the supply lines.

In the case of exposure to humans, the required limit values are observed when the products are used in line with the intended use and the recommended distance of at least 20 cm is observed.

If these limit values are complied with, according to current scientific knowledge, no health-endangering effects from EMF exposure are to be expected. If wearers of prostheses (implants, metal parts in and on the body) as well as active physical aids (pacemakers, insulin pumps, hearing aids, etc.) are in the vicinity of components of the PV system, they must consult with the responsible doctor regarding possible health risks.

In certain cases, even though a device complies with the standard limit values for emissions, it may affect the application area for which it was designed (e.g., when there is equipment that is susceptible to interference at the same location or if the site where the device is installed is close to either radio or television receivers). If this is the case, the operator is obliged to take action to rectify the situation.

The information on the Fronius Wattpilot must not be removed or painted over. The notices and symbols warn against incorrect operation, as this may result in serious injury and damage.

Compatibility with the connected devices (see list below), suitable data communication, and a Fronius Smart Meter at the feed-in point are prerequisites for using certain Wattpilot functions (e.g., PV surplus).

Suitable Fronius inverters

*Requirement:

**Requirement:

Suitable generators can be inverters or wind power plants, for example. A prerequisite for compatibility with external generators is that no other self-consumption controllers (with e.g., battery, power-to-heat) are operated in parallel. This can lead to photovoltaics optimization (PV optimization) malfunctions. The proportion of energy consumed by other loads is not taken into account in the Fronius Solar.wattpilot app, as the power is only known at the grid connection point.

Requirement:

*requires Fronius Datamanager Box 2.0 (item number 4,240,125)

The kWh display is located below the operating mode buttons and alternately displays the following values.

Session kWh
Displays the charged energy of the current charging process.

Total kWh
Displays the total charged energy of all charging processes.

Power kW
Displays the current charging power.

The ID chip can be used to personalize access to the Fronius Wattpilot. 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" and "Authentication required" (see Access management on page (→)). Charging with authentication activated can be carried out after scanning the supplied ID chip or by providing confirmation in the app. To scan, hold the ID chip directly in front of the card reader of the Wattpilot.

Each ID chip can be assigned a name in the app under "ID chips". The stored charging amount per ID chip can be viewed in this menu (see ID chips on page (→)).

No authentication is required in order to assign the charging amount to the ID chips.

The reset card resets all settings (e.g. access management, WLAN, and LED settings) to the factory settings. The device can also be reset using the Fronius Solar.wattpilot app. The taught-in ID chips and the corresponding charging amounts continue to be stored.

The following information is printed on the reset card.

Resetting the Wattpilot

NOTE!

Keep the reset card safe!

The reset card contains all access data.

TIP: Place the reset card in the supplied self-adhesive transparent bag and keep it in a safe place.

The Wattpilot can be used like any other charging station. Actuating an operating mode button (see Operating mode buttons on page (→)) allows the user to switch between the different charging modes (see Different charging modes on page (→)).

The Wattpilot can be used like any other charging station. Actuating an operating mode button (see Operating mode buttons on page (→)) allows the user to switch between the different charging modes (see Different charging modes on page (→)).

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 vehicle, it makes sense to switch to 3‑phase charging at a higher PV surplus. This allows higher maximum charging power levels to be achieved.

The phase changeover can be set automatically or manually (see PV surplus on page (→)).

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 technical specialist in accordance with the applicable regulations (see Grid settings on page (→)).

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 inverter on page (→)).

Setting limit values ensures that the available PV surplus power is distributed to the loads. The limit values created allow a PV battery to be sufficiently charged or the energy to be stored in the form of hot water. The surplus PV power is then 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 vehicle 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

	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 limit value" and "Ohmpilot limit value" 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
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.

*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.

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.,

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 on the electricity exchange. Additional costs may apply depending on the provider.

Example

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

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 (perform setting in the app). 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.

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

Charging with a low charging current is more gentle on the vehicle, whereas charging at a high charging current enables rapid charging. Charging takes place from the grid if necessary.

Charging with a low charging current is more gentle on the vehicle, whereas charging at a high charging current enables rapid charging. Charging takes place from the grid if necessary.

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
The Eco Mode can be configured under Cost optimization (see page(→)) and activated by pressing the operating mode button 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 15:00 hrs, 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 20:00 hrs. Between 02:00 and 05:00 hrs, the electricity price falls below the defined price limit. The electric vehicle is charged with cheap electricity during this period.

Charging in Eco Mode

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 at the most cost-effective time window. The PV surplus and flexible electricity tariff settings are taken into account. If the Stay in Eco Mode function is activated (for activation see Next Trip Mode on page (→)), the Wattpilot continues charging with low-cost energy after the set charging amount has been reached.

The charging amount is specified in kilometers and calculated on the basis of an average consumption (18 kWh/100 km). External conditions (such as season, driving speed, vehicle model) 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 set charging amount is charged in addition to the charging amount available in the electric vehicle.

Enable
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 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 calculation of 100 km. The electric vehicle is plugged in and charged at approximately 15:00 hrs. 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.

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

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

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. Any number of 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

(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.

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.

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.

Another inverter can be paired via the Fronius Solar.wattpilot app (see Cost optimization on page (→)).

The Fronius Solar.wattpilot app can be used to commission, configure, operate, visualize, and update the Wattpilot. The app is available for Android™ and iOS^®.

The Fronius Solar.wattpilot app is available on the following platforms.

IMPORTANT!
In Germany, to comply with the documentation obligation set out in Section 14a of the EnWG (law on the fuel and electricity industries) the Wattpilot must be permanently connected to the Internet in order to be able to verify implementation of the external control commands.

New or connected Wattpilot devices can be added in the Fronius Solar.wattpilot app.

Charging is carried out as cheaply as possible using surplus PV current (see PV surplus on page (→)) and a flexible electricity tariff (see Flexible electricity tariff on page (→)).

Activating "Next Trip Mode"

Activating "Eco Mode after Next Trip Mode"
After reaching the set range, the Wattpilot remains in Next Trip Mode and continues charging with the Eco Mode settings.

Charging is carried out as cheaply as possible using surplus PV current (see PV surplus on page (→)) and a flexible electricity tariff (see Flexible electricity tariff on page (→)).

Activating "Next Trip Mode"

Activating "Eco Mode after Next Trip Mode"
After reaching the set range, the Wattpilot remains in Next Trip Mode and continues charging with the Eco Mode settings.

The current level (charging power) can be adjusted in the app in ampere steps.

Under "Cost optimization", you can activate taking the electricity tariff into account (see Flexible electricity tariff on page (→)) and the use of PV surplus (see PV surplus on page (→)). You can also customize the settings listed below.

Use flexible electricity tariff
Enable or disable, and select the appropriate country from the list below. Either select the flexible electricity tariff of a provider if available, or select a tariff zone.

Eco Mode price limit
If the flexible electricity tariff is enabled in Eco Mode, charging only begins when the specified 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 enabled, the Wattpilot uses the surplus PV energy for charging.

Inverter
Select a coupled inverter.

PV battery threshold
If a battery is integrated into the PV system, the "Discharge PV battery" function can be enabled and the following limit values can be set:

Ohmpilot limit value – optional
If a Fronius Ohmpilot with a temperature sensor is installed in the PV system, a limit value for the temperature can be set here. Below the set value, preference is given to heating with the available energy. Above this value, the vehicle is charged instead of heating with the Ohmpilot. The temperature can still increase slowly.

PV surplus – advanced settings
You can set a Start-up power level from which the PV energy is used for charging in the advanced settings. Vehicles require a certain minimum power to charge.

Vehicles are regulated in increments, so there may be deviations in the use of PV surplus. The following settings can be made under Control behavior.

Vehicle – advanced settings
During smart charging, the charging process can be interrupted or the charging current reduced to meet certain charging conditions. Set vehicle-specific settings to ensure the smart charging process runs smoothly.

The "Charging timer" setting limits charging to specific times. A start and end time must be specified for this. Several time windows can be set. The following can be set:

Set whether charging with PV surplus is allowed at the defined time windows (with permitted or blocked charging).

Proceed as follows to call up the "Grid settings".

Dynamic load balancing can be selected and set under "Load balancing".

Load balancing off

With this setting, no load balancing is carried out by the Wattpilot.

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:

Change the name of the paired Wattpilot.

Set LED brightness values. By activating "Switch off LEDs after 10 s in standby", the LEDs on the device are switched off after 10 seconds in standby.

Set the time zone. Activating "Automatic summer time changeover" automatically sets the summer and winter time.

In the "Access management" menu, it is possible to set whether charging is started automatically or after confirmation. In addition, mode selection and current level selection can be set using the pushbutton on the device.

Authentication

Scan the ID chip

1Hold the ID chip in front of the card reader on the Wattpilot.

2Five LEDs light up green.

✓Charging starts.

Activation or deactivation of the grounding test. It is necessary to deactivate the grounding test in insulated grids in some countries (e.g., Norway).

Up to 10 ID chips can be used. The ID chip is used for authentication and for recording user-specific charging amounts.

The password protects against unauthorized access to the Wattpilot.

Password guidelines

Technician password
If the technician password is activated, it is required to access Grid settings, Digital input and Load balancing.

Proceed as follows to call up the "Grid settings".

Choose country

Max. charging current
This setting is used to adjust the maximum charging current of the Wattpilot. Higher charging currents can no longer be selected.

General - Random maximum delay
Random charging start delay when using flexible electricity tariffs, charging timer or after a power failure. Random delay means that the grid is not overloaded when several Wattpilots start charging at the same time.

Phase unbalanced load
Activate and set the maximum asymmetry. Set the maximum asymmetry in accordance with the applicable regulations. Also see Phase unbalanced load on page (→).

The digital input (DI_1) can be used with the Fronius Wattpilot Flex.

The digital input in the grid lead can be used to limit the charging current, e.g., for charging unlocking via a keylock switch, for the grid operator to connect to a ripple control receiver, or for Article 14(a) EnWG (Energy Industry Act).
The digital input settings can be configured in the Solar.Wattpilot app (Settings > Digital input) and protected with the technician's password (Settings > Password > Protect digital input).

The following connection options can be configured in the "Internet" menu:

The following connection options can be configured in the "Internet" menu:

The charging point communication standard OCPP (Open Charge Point Protocol) is a universal communication protocol for charging infrastructures. It enables communication between the Wattpilot and a management system, via which, for example, load distribution of an infrastructure or billing can be carried out. It can be set up via a remote server provider or locally.

Activate OCPP
Activation or deactivation of OCPP.

Address
The address of the OCPP server must be provided by the provider and entered in the OCPP menu of the app.

Phase assignment
Implement settings for how the phases of the Wattpilot are assigned compared to a Smart Meter. This is necessary, for example, to ensure that load balancing functions correctly.

Custom certificate
Possibility to enter a self-created certificate for OCPP.

Alternative ID
If a charging process is started without authentication with an ID chip (Access management > Authentication > Open), an alternative ID can be stored and sent to the backend.

After confirming the restart, the Wattpilot is restarted; the most recent settings remain saved.

The current firmware of the Wattpilot is loaded via the Internet. The "Internet" menu shows which firmware version is installed and whether an update is available.

The Fronius Solar.wattpilot app can be updated via the respective platform (Google Play Store, App Store).
