Explanation
Specific loads connected to 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 favorable time periods for optimization of internal
power supply and self-consumption. In accordance with the PV sys-
tem operator's specifications and taking the determined time periods
into account, the Sunny Home Manager controls the switching on
and -off of the loads.
Furthermore, radio-controlled sockets provide the option of individu-
ally monitoring and recording the energy consumption of loads.
The Sunny Home Manager can control supported devices from
Miele & Cie. KG via a Miele@home gateway**.
The Sunny Home Manager uses the yield forecast and the load pro-
file to determine favorable time periods for optimization of internal
power supply and self-consumption. In accordance with the PV sys-
tem operator's specifications and taking the determined time periods
into account, the Sunny Home Manager controls the switching on
and -off of the Miele devices.
The Sunny Home Manager can control devices using a data ex-
change protocol defined by SMA Solar Technology AG by commu-
nicating with the devices either directly or via an appropriate gate-
way using Ethernet. The device reports its energy demand to the
Sunny Home Manager and the Sunny Home Manager allocates the
available energy to the device taking the PV yield forecast and the
consumption forecast into account. You can find out whether the
data exchange protocol used by the device is supported by the
Sunny Home Manager in the device documentation or from the de-
vice manufacturer.
The Sunny Home Manager prevents derating losses which can arise
due to the limitation of active power feed-in. Taking the PV yield
forecast and the consumption forecast into account, the timing and
duration of battery charging are controlled and the battery charge is
optimized according to the available energy supply, if excess PV en-
ergy cannot otherwise be used.
