3.1 Sunny Home Manager
3.1.1 Functions
The Sunny Home Manager is a device for monitoring PV systems and for controlling loads in
households with PV systems. The Sunny Home Manager carries out the following tasks:
• Read-out of energy meter data and data from SMA devices with BLUETOOTH or Speedwire
communication interface
• Sending of data to Sunny Portal
• Support for increased self-consumption
• Limitation of active power feed-in
• Implementation of grid management services via Ethernet-based communication
Read-out of 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 ex works fitted with Speedwire or BLUETOOTH or they can be
retrofitted accordingly (see product page of the respective inverter at www.SMA-Solar.com).
Energy meter data from combined heat and power plants and other non-PV-specific generation plants
is not supported.
PV System Monitoring and Parameterization via 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.
Using Sunny Portal, and taking the different electricity prices into account, the Sunny Home Manager
provides recommendations for the prudent use of electrical energy.
14 HoMan_Portal-BA-en-17 User Manual
SMA Solar Technology AG 3 Product Description
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, as loads are operated while PV power is
produced (e.g. oven) and because certain loads continuously consume current (e.g. refrigerators,
devices in standby mode). If the PV system produces a lot of PV power, it is possible that only a part
of the 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

Creation of a load profile The Sunny Home Manager logs the PV generation, the grid feed-in,
Control of
SMA radio-controlled
sockets
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.
and the purchased electricity. Based on PV g enerati on, gri d feed-in and
purchased electricity, the Sunny Home Manager determines how
much energy is typically consumed at certain times and uses this to
create a load profile for the household. This load profile can be
different for each day of the week.
The Sunny Home Manager obtains the PV generation data from the
connected SMA inverters, from an SMA Energy Meter, or from
another energy meter. The Sunny Home Manager receives the data on
grid feed-in and purchased electricity from one SMA Energy Meter or
at least one other energy meter.
Specific loads connected to SMA radio-controlled sockets can be
switched on and off by the Sunny Home Manager. The
Sunny Home Manager uses the PV 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 system
operator's specifications and taking the determined time periods into
account, the Sunny Home Manager controls switch-on and switch-off
of the loads.
Also, SMA radio-controlled sockets provide the facility to individually
monitor and record the energy consumption of loads.

Function Explanation
Control of Miele devices
via the Miele@home
system
The Sunny Home Manager can control devices from Miele & Cie. KG
via a Miele@home Gateway**. The Sunny Home Manager uses the
PV 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 system operator's specifications and taking
the determined time periods into account, the Sunny Home Manager
controls switch-on and switch-off of the Miele devices.
Direct control of devices
via a data exchange
protocol
The Sunny Home Manager can control devices using a data exchange
protocol defined by SMA Solar Technology AG by communicating
with the devices either directly or via an appropriate gateway 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
pr oto col use d by the dev ice is s upp ort ed b y th e Su nny Hom e Ma nager
in the device manual or from the device manufacturer.
When used with SMA
battery 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 also controlled and the battery is
charged optimally in accordance with the available energy supplies,
if excess PV energy cannot otherwise be used.
When used with SMA
battery inverters:
Optimized discharging
behavior for lead-acid
batteries
The Sunny Home Manager uses the calculated load profile and the PV
yield forecast to control battery discharge. The battery is discharged
when the following criteria are met:
• It is possible for the battery to be discharged to a point where
sufficient storage capacity is free to absorb the amount of PV
energy forecast for the next battery charge.
• The discharged lead-acid battery can then promptly be charged
with excess PV energy.
The use of these criteria ensures that the lead-acid battery is conserved
while making optimum use of the battery capacity.

SMA Solar Technology AG 3 Product Description
Limitation of active power feed-in
Local regulations, for example, the Renewable Energy Sources Act (EEG) in Germany, can call for
permanent limitation of active power feed-in for your PV system, tha t is , a l imi tat ion of t he a ctiv e po wer
fed into the utility grid to a fixed amount or a percentage share of the installed nominal PV system
power. If required, ask your grid operator whether a permanent limitation of the active power feed-in
is necessary and whether you are allowed to use the Sunny Home Manager for this purpose (see the
Manufacturer's Declaration "Feed-In Management In Accordance with the Renewable Energy
Sources Act (EEG) 2012 with SMA Sunny Home Manager (SHM) from SMA" available at
www.SMA-Solar.com).
Using an SMA Energy Meter or a suitable feed-in meter, the Sunny Home Manager monitors the
active power that is fed into the utility grid. If the active power feed-in exceeds the prescribed limit, the
Sunny Home Manager limits the PV generation of the inverters accordingly.
The Sunny Home Manager avoids derating losses due to limitation of PV power generation by taking
the current self-consumption of the household into account. Sunny Hom e Ma nag er h elps to us e ex ces s
PV power in households directly and increases the self-consumption quota as a result. For PV systems
with SMA battery inverters, the Sunny Home Manager preferentially uses the derated active power
to charge the battery.
Example: Limitation of the active power feed-in to 70% of the nominal PV system power
Due to high levels of solar irradiation, the system can currently produce 90% of the nominal
PV system power.
• At this time, 20% of the nominal PV system power is being consumed by loads in the
household. The remaining 70% of the nominal PV system power is being fed into the utility
grid.
☑ No limitation of PV generation is required.
• A load is switched off and only 10% of the nominal PV system power is consumed in the
household. As a result, 80% of the nominal system power is available for feed-in to the utility
grid – more than allowed.
☑ The Sunny Home Manager reduces PV generation from the theoretically possible 90% of
nominal PV system power to 80%. 70% of the nominal PV system power continues to be
fed into the utility grid.
Implementation of Grid Management Services via Ethernet-Based
Communication
As part of grid management services, it may be necessary to implement grid operator specifications
for active power limitation and for reactive power feed-in (e.g. the active power feed-in of your PV
system will be reduced in the event of grid overloads).
The Sunny Home Manager can implement specifications for grid management services, which the
grid operator sends via Ethernet-based communication to the Sunny Home Manager. If applicable,
ask your grid operator whether your PV system is required to implement grid management services.
