Fig. 4 sonnenEvo Connection Concept
The sonnenEvo is an intelligent storage system
that monitors and controls energy production,
consumption and storage in the house. The storage
system is connected to the grid via the main load
panel.
The sonnenEvo can work with existing or newly
installed PV systems. The PV array does not
connect to the storage system directly. The storage
system uses a power meter and current transforms
to monitor PV power generation and energy
consumption in the building.
The sonnenEvo offers three modes of operation:
Self-consumption, Backup and Time of Use.
Self-consumption mode
Self-consumption is the part of the generated
PV power that has been either consumed at home
or stored in the battery. This is the default mode
of operation.
Generation > Consumption
If the generation of PV power is higher than the
consumption such as at midday, there is a surplus
of electrical energy. In this case the surplus energy
is used to charge the battery of the storage
system.
If the entire portion of the surplus cannot be
charged into the battery, the remaining surplus is
fed into the public electricity grid.
Consumption > Generation
If the consumption is higher than the generation
of PV power such as in the evening, there is a
deficit of electrical energy. In this case the battery
of the storage system is discharged to offset
as much of the deficit as possible. If the entire
deficit cannot be compensated by discharging the
battery, the remaining deficit is covered by the
public electricity grid.
The storage system also acts as a backup power
supply, meaning that if the utility grid goes out,
