Fronius Wattpilot

FREQUENTLY ASKED QUESTIONS

On this page we answer many questions about the Fronius Wattpilot.

General

For basic charging, all you need to do is connect the Wattpilot to the power supply and plug in your car. You can use the Solar.wattpilot app for special settings (PV optimisation, charging modes, etc.).
You can integrate the Wattpilot into a network using WLAN. If the Wattpilot is outside WLAN range, you can boost the WLAN signal using a repeater, WIFI Access Point or PowerLine adapter.
The warranty term is 2 years. 
Yes, you can do that. You can run as many Wattpilots in parallel as you like. Each Wattpilot must be individually integrated into the network. However, PV optimisation only ever works on one device.
You can use the Fronius Wattpilot to charge any electric vehicle. The type 2 socket even lets you charge vehicles with a type 1 connection. Just use the appropriate charging lead for the vehicle. 
Wattpilot Go is a mobile charging solution that you can use whenever you’re away from home.
RFID stands for “radio frequency identification”. This ID chip is used for authentication, e.g. to let you unlock the Wattpilot. The authentication step is only really important if you mount the Wattpilot in a publicly accessible place, such as an underground car park. Multiple ID chips can also be used for one Wattpilot to enable a number of different people to charge their vehicles on the same device. However, in this case the power usage will be recorded separately. 
If you have questions about the Wattpilot, you can always speak to your installer. You will also find all sorts of additional information about the Wattpilot on our website and on the Fronius YouTube channel.
The scope of supply of the Wattpilot includes the following: mounting bracket, incl. screws and rawlplugs, Wattpilot, miniature fuse, anti-theft device, reset card, ID chip and Quick Guide. The following are available as optional extras: a type 2 cable (5 m), ID chips (10 x), an extra mounting bracket and various adapter kits.
The Wattpilot is made in Austria. 
Wattpilot 2.0 has been developed based on a normative change (IEC 61851-1:2019 and IEC 62752:2016). This standard only concerns the manufacturer. The previous version of Wattpilot 2.0 may still be sold and used.
The Wattpilot 2.0 is produced with a newly designed housing. This ensures a higher IP protection (IP 55 instead of IP 54). The safety plug adapter cable is produced in a shorter length. The WLAN range has also been improved. In line with our sustainability strategy, more components from Europe are used to avoid long transport routes. Furthermore, there are two new versions of the Wattpilot 2.0: the Wattpilot Home 22 J 2.0 and the Wattpilot Go 22 J 2.0 AUS (for Australia). All known software features like PV surplus charging etc. are still available for Wattpilot (1.0) as well as for Wattpilot 2.0.

Installation and start-up

You will need to use the Solar.wattpilot app when starting up the Wattpilot for the first time. The Wattpilot must be connected to the Internet to enable various settings to be made and for remote access. 
Yes! There are no additional, recurring checks and therefore no need for any servicing.
You can simply plug the Wattpilot Go into any CEE16 or 32 socket. The Wattpilot Home needs its own permanently wired connection. Installation and commissioning by an installer is recommended for both versions, and does not take long at all.
The Wattpilot can be mounted upright indoors or outdoors. It has protection class IP 54 meaning the Wattpilot can be exposed to rain without detriment. Exposure to direct sunlight should be avoided.

Features

You can change the charging mode either using the app or a button on the device.
No, it is not possible to do this. However, you can set it to charge to a specific power level in kWh or km, and the electric car will then be charged to this level within a defined time period.
No, the Fronius Wattpilot does not allow you to do this. 
There are two options for visualising the Wattpilot: either using the Solar.wattpilot app or alternatively Solar.web. For visualisation in Solar.web, your installer will also install a secondary Smart Meter.
No, not at all! The Wattpilot can be used with or without a PV system with the same results. However, charging will cost you less if you use electricity you produce yourself using your solar panels. 
The LEDs provide information on the charging current, the type of charging (1-phase or 3-phase), installation of an update, etc.
It is easy to switch to a variable electricity tariff. You can find detailed information on how to switch on the energy provider’s website.

As it stands, there is still no standard for intelligent charging. For this reason, there may be limitations with cost-optimized charging for certain models of car. Fronius endeavours to configure the optimal charging behaviour for every vehicle.The following models of car are affected:

  • Renault Zoe
  • Twingo
  • Kia e-Soul
  • Mitsubishi i-MiEV
  • Citroen C-Zero
  • Peugeot iOn
  • VW ID.3 / ID.4  (Due to the charging behaviour, charging must not be interrupted) 

The selection of the car model can be found in the Solar.wattpilot app in Settings - Cost optimisation - Car.

No. The Wattpilot can also be used without a variable electricity tariff. 

All settings can also be set locally, directly by connecting to the Wattpilot’s hot spot. This is permanently open and secured with a password.The following functions are not possible without a network connection:

  • Remote app access via the internet
  • Coupling with the PV system (PV-optimised charging)• Use of flexible electricity tariffs
  • Software updates

Solar.wattpilot App

You can download the app from the Google Play Store (Android) and the Apple App Store (iOS). 
English, German, French, Italian, Dutch, Swedish, Spanish, Hungarian and Finnish
All information about the amount of electricity charged is displayed in the Solar.wattpilot app.

solar.web

Yes, multiple Wattpilots can be added to a PV system in Solar.web.
You can add your Wattpilot to your PV system in Solar.web in the tab "Settings" - "Components". 

If you have not yet created a PV system in Solar.web, register on www.solarweb.com and add your Wattpilot and paired inverter when creating the new PV system. When adding the Wattpilot to Solar.web we recommend that the Wattpilot currently has internet connection and is paired with the inverter. Nevertheless it is also possible to add an offline Wattpilot to Solar.web, but Wattpilot data will first be shown, when the Wattpilot is online and paired.

For Wattpilot data to be displayed in Solar.web, ensure the following:

  • The Wattpilot (as well as your inverter) must be added to your PV system in Solar.web in the tab "Settings" - "Components". If this tab is not visible, please ask your installer to assign you "Owner" or "Supervisor" rights for your PV system.
  • Both the Wattpilot and the paired inverter must be connected to the internet.The Wattpilot requires firmware version 36.0 or higher.
  • You can update your Wattpilot in the Solar.wattpilot app in the tab "Internet".
  • The Wattpilot needs to be paired with your inverter. Go to the tab "Settings" - "Cost Optimization" in the Solar.wattpilot app to pair your Wattpilot with an inverter.
  • If the paired inverter is a GEN24 or Tauro, firmware version 1.12 or higher is required. You can update your inverter in Solar.web in the tab "Settings" - "Components".
The Wattpilot must be paired with the new inverter in the Solar.wattpilot app in the "Settings" - "Cost optimization" tab. The inverter must be replaced in Solar.web in the "Settings" - "Components" tab. Afterwards, all Wattpilot data will be displayed again in Solar.web.

If the Wattpilot has no internet connection (e.g. due to weak WLAN), live and history data is not available in Solar.web. History data will not be restored when the Wattpilot reconnects to the internet.

Furthermore, Wattpilot data is only shown if the Wattpilot is paired with an inverter of the same PV system in Solar.web. For example, no data is displayed in Solar.web for periods when the Wattpilot Go is used on the go.
