Function Explanation
Control of radio-controlled
sockets
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.
Control of Miele devices via
the Miele@home system
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.
Direct control of devices via
a data exchange protocol
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.
When used with SMA bat-
tery inverters: prevention of
derating losses
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.
