Household consumption
In Eco Mode, the electric vehicle is connected to the Wattpilot at around 15:00, as
although a fixed additional range for the electric vehicle is not necessary, cheaper electri-
city 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 optimisation. 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.
Between 02:00 and 05:00, the electricity price falls below the defined price limit. The
electric vehicle is charged with cheap electricity during this period.

Next Trip 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 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) 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 kilometres and calculated on the
basis of an average consumption (18 kWh/100 km). External conditions (season, driving
