Austrian expert in energy solutions is launching the Fronius Wattpilot in May
2021. The Wattpilot is aimed at all electric car drivers, regardless of whether
they have their own photovoltaic system or not. It is particularly easy to install
and is one of the few products on the market which can switch between
single-phase and three-phase surplus charging, allowing customers to get the
most out of their PV system.
“The Fronius Wattpilot is
an intelligent charging solution which allows electric car drivers to enjoy
maximum independence and to always charge their car at the lowest possible
cost,” explains Martin Hackl, Global Director of the Business Unit
Solar Energy, Fronius International GmbH. “Our aim was to develop an installer-friendly and customer-friendly
e-mobility solution and that is what we’ve done – the Fronius Wattpilot is easy
to install, commission and use,” he adds.
Even if an electric car driver doesn’t yet have a PV system, it is
advisable to start thinking about the right charging solution now, since not
all devices can be operated intelligently in combination with a PV system. “The Fronius Wattpilot already enables
customers to fill up their electric car with self-generated PV current,”
notes Martin Hackl.
User-friendly operation via app
The Solar.wattpilot app makes it easy to commission and operate the
charging solution. It also offers users a visually appealing overview of the
status of the charging operations. The app runs on iOS and Android and is the
only user interface needed to operate all functions clearly and easily.
The cheapest reliable charging
You can charge an electric vehicle very cheaply on a variable
electricity tariff1. These are based on the current electricity
exchange prices and are passed directly to customers with very little
surcharge. Users simply define the maximum electricity price for charging their
electric car using the Solar.wattpilot app. As well as the variable electricity
tariff, there are two other measures you can take to fill up your car as
cheaply as possible: use the Next Trip Mode charging mode and the option of
only using surplus PV for charging.
Charging an electric vehicle with as much solar energy as
Charging solutions must be able to follow the sun. If there’s a lot
of solar energy available, more charging takes place, when there is little
solar energy available, less charging takes place. The Fronius Wattpilot is
excellent at utilising the surplus PV and controls in 1-ampere increments up to
the maximum charging power. “This brings
as much solar energy to your vehicle as possible,” says Martin Hackl,
The Fronius Wattpilot is one of just a handful of products on the
market that can switch between single-phase and three-phase charging. This
means that all the surplus PV from 1.38 kW to 22 kW is used. Charging takes
place in ampere increments and the single/three-phase switchover is fully
automatic. Unlike conventional solutions, this prevents brief but expensive
Intelligent charging modes for every situation
The Wattpilot also has two different charging modes: Eco and Next
Trip Mode. Depending on the situation, the electric vehicle is either charged
highly economically or up to a specified charge level for the next planned
trip. Eco Mode is ideal for owners of PV systems, as it combines the surplus PV
charging with the variable electricity tariff. Next Trip Mode allows users to
charge the vehicle with energy for a specific journey. This ensures that there
is at least enough energy for the upcoming trip, using the cheapest available
Combining e-mobility and photovoltaics brings an array of
advantages “The Fronius Wattpilot is
aimed at all electric car drivers, whether they have a PV system or not,” explains Leonhard Peböck, Product Marketing Solar Energy, Fronius
International GmbH. “But the main
advantages come from combining e-mobility and photovoltaics.” The cost
effectiveness of PV systems, as well as of electric cars, is improving. The
reason is that self-generated solar energy is being used for charging, meaning
that less power is needed from the grid. “You
produce the electricity for your mobility yourself, sustainably and at the
lowest cost,” reports Peböck.
The Wattpilot rounds off the Fronius range of solutions. Its
introduction means that there is now a product with proven Fronius quality
available not only for the PV and heat sectors, but also for the mobility sector2.
The Fronius Wattpilot comes in two versions: a permanently mounted Wattpilot
Home for home and the mobile Wattpilot Go for on the move.
