Priority in the inverter Wattpilot Battery**
Battery** Priority 2 until SOC*,
then 1
Priority 1 until SOC*,
then 2
*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 bat-
tery 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 electricity 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 elec-
tricity 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)
