SMA Solar Technology AG
The Sunny Home Manager establishes the connection to Speedwire devices via a router / network
switch in the local network.
SMA inverters are either fitted with Speedwire or BLUETOOTH ex works or can be retrofitted
accordingly (see product page of the respective inverter at www.SMA-Solar.com).
PV System Monitoring and Parameterization via Sunny Portal
Sunny Portal serves as the user interface of the Sunny Home Manager. The Sunny Home Manager
establishes the Internet connection to Sunny Portal via a router and sends the read-out data to
Sunny Portal.
Using Sunny Portal, the Sunny Home Manager enables monitoring of the system, a display of the
PV energy available over the course of the day, and a live display of all energy flows in the
household. Taking the different electricity prices into account, the Sunny Home Manager uses this to
derive recommendations for the prudent use of electrical energy.
Support for Increased Self-Consumption
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 loads (e.g. oven) are in operation
while PV power is being produced and because certain loads continuously consume current (e.g.
refrigerator, devices in standby mode). If the PV system produces a lot of PV power, it is possible
that only a part of that PV power will be self-consumed. The excess PV power is fed into the utility
grid.
A higher self-consumption quota can be achieved if loads are specifically switched on when excess
PV power is available.
The following functions of the Sunny Home Manager make it possible to increase the self-
consumption quota:

Creation of a PV yield fore-
cast
Creation of a load profile

Explanation
The Sunny Home Manager continuously logs the energy generated
by the PV system. The Sunny Home Manager also receives location-
based weather forecasts via the Internet*.
Based on this information, the Sunny Home Manager creates a PV
yield forecast for the PV system.
The Sunny Home Manager logs data on PV generation, grid feed-in
and purchased electricity. Based on PV generation, grid feed-in and
purchased electricity, the Sunny Home Manager determines how
much energy is typically consumed at which times and uses this to
create a load profile for the household. This load profile can be dif-
ferent for each day of the week.
The Sunny Home Manger receives the measured data for PV gener-
ation, grid feed-in and purchased electricity via the installed energy
meters (S0, D0 or SMA Energy Meter) or from the inverters directly
via the data connection.
