Reading Out Energy Meter Data and Data from SMA Devices with BLUETOOTH
or Speedwire Communication Interface
The Sunny Home Manager reads out the data of the connected energy meters and SMA devices.
The Sunny Home Manager is connected to the energy meters via network cables.
The Sunny Home Manager establishes the wireless connection to the BLUETOOTH devices
(e.g. SMA radio-controlled sockets) via BLUETOOTH.
The communication between the Sunny Home Manager and an SMA inverter is possible either via
BLUETOOTH or via Speedwire. It is not necessary for all inverters in a PV system to use the same
interface. The Sunny Home Manager can manage and regulate inverters with BLUETOOTH and
inverters with Speedwire as one PV system.
The Sunny Home Manager establishes the connection to Speedwire devices via a router/network
switch in the local network.
SMA inverters are either available fitted with Speedwire or BLUETOOTH ex works, or they 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 and sends the read-out data to Sunny Portal via a
router.
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 derives from
this 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:
Function Explanation
Creation of a PV yield
forecast The Sunny Home Manager continuously logs the energy generated by
the PV system. It 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.
