In this example, the Production pie chart on
the left indicates that the homeowner produced
151.25kWh of energy for that day. Using their
sonnenBatterie storage system, they were able to
use 62.1% of the energy that they produced with
their solar system. The other 37.9% was fed back
into the grid.
The Consumption chart on the right indicates
that the homeowner consumed 93.9kWh of
energy that day. It also shows that with the help of
their sonnenBatterie, the homeowner produced
93.9% of the energy they used that day with solar
power! Only 2.4% of the energy they used had to
come from the grid.
Time of Use Mode Use Case
If the sonnenBatterie is set to Time of Use
mode, the daily consumption and production
cycle will look very similar to the self-consumption
cycle, except the sonnenBatterie will only begin
discharging at specific times at night to ensure
that loads generated during peak energy periods
are covered.
Backup Mode Use Case
This section will provide an example of a typical
history graph for a sonnenBatterie set to Backup
mode.
As in self-consumption mode, in this weekly
backup mode graph, you can see the transition
from day to night as the PV production
reading rises and falls in daily cycles. The home
consumption is also relatively steady until sunset
where energy consumption tends to increase.
In backup mode, the sonnenBatterie does not
discharge throughout the day, instead reserving
power to restore energy to the home in the event
of an outage. Accordingly, the State of Charge,
as indicated by the purple line at the top of the
graph, stays relatively constant (small fluctuations
are normal).
Underneath this graph are the Production
and Consumption pie charts, which show how
much of your own energy you are producing
and consuming. In this example, the Production
chart on the left indicates that the homeowner
produced 190.36kWh of energy for that day
using their home solar system. They were able to
consume 32.7% of the energy that they produced
with their solar system. The other 67.3% was fed
back into the grid.
The Consumption chart on the right indicates
that the homeowner consumed 105.75kWh of
energy overall that day. It also shows that the
homeowner produced 54.7% of the energy they
consumed and purchased the remaining 45.3% of
the energy they consumed from the utility grid.
