Support in increasing the self-consumption rate
Self-consumption means that the PV power is consumed at the site where it is generated.
In every household, there is "natural" self-consumption, because electrical loads (e.g., oven) are in
operation while PV power is being produced and because certain electrical loads continuously
consume current (e. g. refrigerator, devices in standby mode). If the PV plant produces a lot of PV
power, it is possible that only a part of the PV power will be self-consumed. The residual PV power is
fed into the electricity grid.
A higher self-consumption rate can be achieved if electrical loads are specifically switched on when
residual PV power is available.
The following functions of the Sunny Home Manager make it possible to increase the
self-consumption rate:

Explanation
The Sunny Home Manager receives location-based weather forecasts via
the Internet and uses them to create a yield forecast for the PV plant.
consumed at certain times in a household and uses this to create a load
profile of the household.
To create the load profile, the following energy meters must be connected
to the Sunny Home Manager:
• One feed-in meter and one consumption meter
or
Bidirectional meter for feed-in and purchased electricity
Specific electrical loads connected to SMA radio-controlled sockets can
be switched on and off by the Sunny Home Manager. The
Sunny Home Manager uses the yield forecast and the load profile to
determine favourable times for increasing the self-consumption rate, and
thus controls the loads.
The Sunny Home Manager can control Smart Grid-ready (SG-Ready)
devices from Miele & Cie. KG via a Miele@home Gateway** .
Smart Grid-ready devices from Miele are marked with the SG-Ready
emblem.
The Sunny Home Manager uses the yield forecast and the load profile to
determine favourable times for increasing the self-consumption rate, and
thus controls the loads. The Sunny Home Manager controls the devices via
the Miele@home Gateway.
