*SOC - State of Charge of the stationary battery
**Fronius-compatible DC coupled battery
NOTE!
The component with the highest priority in the inverter is taken into account.
If, for example, a battery in the inverter is prioritised higher than an Ohmpilot
and the battery limit value is set to 50% and the Ohmpilot limit value is set to
50 °C, the Wattpilot will start charging when the battery reaches 50% SOC. The
Ohmpilot is not supplied with energy until the electric vehicle and battery are
fully charged.
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.
Flexible electri-
city tariff
The flexible electricity tariff can be used if electricity is purchased from electri-
city retailers and charged for hourly via the electricity exchange, e.g.
-
Lumina Strom hourly (available in Germany, as at 01/03/2021) or
-
aWattar hourly (available in Austria and Germany, as at 01/03/2021).
The Wattpilot queries the retailer tariffs directly via the Internet. It is possible to
specify a price threshold (Eco Mode price limit) below which charging starts. This
is the pure electricity price, without network charges or other fees.
Example
The following figure shows the electricity price of an electricity retailer (Lumina
Strom hourly, aWattar hourly) over 24 hours. The hourly tariffs are retrieved from
the electricity exchange at a specific time for the next day.
Information regarding electricity retailers with a flexible electricity tariff can
be found under

Lumina Strom hourly (as at 01/03/2021)
-
aWattar hourly (as at 01/03/2021)
