2 Safety
2.1 Intended Use
The SunnyHomeManager is the central product responsible for energy management in households with a
photovoltaics (PV) system and battery-storage system for self-consumption. The SunnyHomeManager continuously
records the solar power generated by the PV system and, if desired, ensures optimal use of the solar power by
combining all suitable energy flows in the household to create an intelligent system and, upon request, control it
automatically.
The online portal Sunny Portal is used to operate and configure the SunnyHomeManager. The user can make all the
required and desired settings here.
The SunnyHomeManager is not an energy meter for power consumption in the sense of the EU directive 2004/22/
EG (MID). The SunnyHomeManager may not be used for billing purposes. The data collected by the
SunnyHomeManager relating to the power generated by your PV system may deviate from the data of the main
energy meter, which is used for billing purposes.
The SunnyHomeManager supports up to 24 devices and can actively control a maximum of 12 devices.
The SunnyHomeManager is not suitable for controlling life-sustaining medical devices. A power outage must not lead
to personal injury. Loads connected to the SunnyHomeManager must have an CE, UKCA, RCM or UL identification
label.
The SunnyHomeManager is approved for use in all EU member states, in Great Britain, Australia and selected other
countries.
The type label must remain permanently attached to the product.
Environment
The product is designed for indoor use only.
The SunnyHomeManager may only be connected to the subdistribution of the household on the load side behind the
energymeter of the electric utility company. The SunnyHomeManager must be installed in a switch cabinet or in a
domestic installation cabinet in the area of the additional applications intended for this as per VDE-AR-N
4100:2019-04.
It is possible to use the SunnyHomeManager in delta IT grids. When using the SunnyHomeManager in delta IT
grids, the cumulative power values are correctly measured. Due to the measuring principle of the
SunnyHomeManager, other measured values may be incorrect.

DHCP Server is recommended.
The DCHP server automatically assigns the appropriate network settings to your nodes in the local network. A
manual network configuration is therefore not necessary. In a local network, the Internet router is usually the
DHCP server. If the IP addresses in the local network are to be assigned dynamically, DHCP must be activated in
the Internet router (see the Internet router manual). In order to receive the same IP address by the internet router
after a restart, set the MAC address binding.
In networks where no DHCP server is active, proper IP addresses must be assigned from the free address pool of
the network segment to all network participants to be integrated during commissioning.
2.3 Cyber Security
Most operating activities such as monitoring and control of systems can be done locally by the PV system operator or
service personnel without the need for data communication via public Internet infrastructure.
In other use cases of systems, the PV systems are also part of the global communication system, which is based on
Internet infrastructures.
The data communication via Internet is an up-to-date, economically viable and customer-friendly approach in order to
enable easy access for the following modern applications such as:
• Cloud platforms (e.g. SunnyPortal)
• Smartphones or other mobile devices (iOS or Android apps)
• SCADA systems, which are remotely connected
• Utility interfaces for grid management services
Alternatively, selected and secured communication interfaces may be used. These solutions are no longer state of the
art and are very expensive to use (special communication interfaces, separate wide area networks and more).
When using the Internet infrastructure, the systems connected to the Internet are entering a basically unsecure area.
Potential attackers constantly seek vulnerable systems. Usually, they are criminally motivated, have a terrorist
background or aim to disrupt business operations. Without taking any measures to protect systems and other systems
from such misuse, a data communication system should not be connected to the Internet.
Communication between the SMA internet platform SunnyPortal and the SunnyHomeManager takes place via the
Webconnect process as well as the HTTPS protocol, i.e. an authenticated and encrypted connection and thus allows
safe online communication.

3 Service Description
The field of applications for the SunnyHomeManager ranges from its use as a simple energy meter to monitoring a
PV system and intelligent energy management.
SunnyHomeManager as energy meter
The SunnyHomeManager detects energy flows in both directions:
• Continuous recording of the energy generated by the PV system
• Measurement of the feed-in of generated energy into the utility grid as well as the consumption of energy from the
utility grid takes place at the point of interconnection.
SunnyHomeManager in systems without self-consumption
Monitoring
Basic PV system status monitoring to confirm correct system performance:
All energy flows are recorded and evaluated. You will be notified about disturbances at an early stage.
Limitation of Active Power Feed-In
Local legal 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 - that is, a limitation of the active power fed into the utility grid to a
fixed amount or a percentage share of the installed nominal PV system power.
The SunnyHomeManager monitors the active power that is fed into the utility grid. If the active power feed-in exceeds
the prescribed threshold, the SunnyHomeManager will limit the PV generation of the PV and hybrid inverters.
SunnyHomeManager in systems with self-consumption
Self-consumption means that the energy produced by your PV system is consumed at the site where it is generated.
Self-consumption reduces the amount of energy that you feed into the utility grid, but also the amount of energy that
you purchase from your grid operator.
Energy Management - Monitoring and Forecast
Creation of a PV generation forecast - based on the location-based weather forecast
Creation of a load profile - based on individual analysis of time-dependent energy consumption:
Taking into account different electricity prices, the SunnyHomeManager makes recommendations for the prudent use
of electrical energy. This allows you to selectively switch on loads at times when electricity is cheap (loads include, for
example, home appliances such as dishwashers, dryers, washing machines, as well as heating and hot water
preparation via heat pumps, and heating elements, but also charging stations for e-mobility).
To learn the load profile, the consumption data should be available over a period of at least 2 weeks.
The forecast generated by the SunnyHomeManager is calculated from the estimated energy balance from generation
and consumption for the next 48 hours.
Optimized self-consumption through load control
The SunnyHomeManager measures the power consumption of all connected loads and records both the power
consumption and the usage time of a load. The SunnyHomeManager uses this individual load profile combined with
the location-based weather forecast to support your increased self-consumption:
To control loads, there are the following options:
• Control of loads that do not communicate directly via switching devices such as radio-controlled sockets or relays,
e.g. Modbus devices that control the SG Ready interface of loads
• Control of directly communicating loads via the standard protocol interfaces EEBus or SEMP
The SunnyHomeManager switches home appliances on automatically when PV energy is available.

Operating manualHM-20-BE-en-1814
Optimized self-consumption through dynamic active power limitation
• Through forecast-based load control, the SunnyHomeManager ensures that even on sunny days excess energy
hardly ever gets lost that has to be "curtailed" due to the limitation of the active power.
• When using SMA battery inverters, the SunnyHomeManager prevents derating losses that can be caused by
limiting the active power feed-in. Taking the PV generation forecast and the consumption forecast into account, the
time and duration of battery charging are chosen so that the battery is charged when PV energy is available.
Increased self-consumption through forecast-based battery charging
The SunnyHomeManager increases the efficiency of your PV system by storing the excess energy generated during
the midday peak, which is not allowed to be fed into the utility grid due to the active power limitation, in batteries.
By means of the location-based weather forecast, the SunnyHomeManager can predict the solar irradiation for some
hours to days and check whether derating losses due to the limitation of PV grid feed-in are to be expected for the
current or following day. This means that in the afternoon of the current day only as much PV energy is charged to the
battery as to ensure that, with the remaining battery charge, grid-supplied power at night and on the morning of the
next day can be avoided. Any derating losses forecast for the following day are avoided by the free storage capacity
of the more heavily discharged battery.
Increased self-consumption through peak load shaving
In systems with SMA battery or hybrid inverters, the self-consumption portion can be additionally increased and more
electricity costs saved by virtually distributing the total storage capacity of the battery between increased self-
consumption and peak load shaving (multi-use). In doing so, the battery can be integrated even more flexibly into your
energy management
• Increased self-consumption - through flexible use of the self-generated solar power stored in the battery at times
when insufficient or no solar power is produced
• Peak load shaving - limitation of power consumption from the utility grid; any increased energy demand at certain
times is drawn from the battery

5.3 Components for Operating the SunnyHomeManager
5.3.1 Basic Operation
The following components are required for operating the SunnyHomeManager:
☐ Internet access via router (for SunnyPortal connection)
☐ PC with web browser
☐ Sunny Portal access
Router
The SunnyHomeManager establishes the internet connection to Sunny Portal via a router.
Via the Ethernet connection of the SunnyHomeManager to the router, the data read out by the integrated measuring
device of the SunnyHomeManager from all devices integrated in the system is sent to the SunnyPortal. The user can
make all the required settings for the SunnyHomeManager system via SunnyPortal.
SunnyPortal
SunnyPortal is an Internet portal which enables you to monitor and configure systems and to visualize system data.
The SunnyPortal system setup assistant is used to commission the SunnyHomeManager (to www.sunnyportal.com/
register)
5.3.2 Operation of a PV system with SMA inverters
The SunnyHomeManager organizes the electricity generated by the PV system and provided by inverters within the
loads in the household. The SunnyHomeManager regulates the feed-in of the residual current into the utility grid at
the point of interconnection.

5 Product Overview
SMA Solar Technology AG
Operating manual 19HM-20-BE-en-18
Inverters can communicate in two different ways with the SunnyHomeManager:
• Wired via SMASpeedwire/Ethernet
The inverter must be connected to the local network via a network cable (e.g. via a router).
• Wireless via SMASpeedwire/Wi-Fi
The SunnyHomeManager does not have its own a Wi-Fi connection, however it can communicate with all
devices connected to the same router.
The SunnyHomeManager supports all inverters with integrated or retrofitted Speedwire interface of SMA Solar
Technology AG. The inverters must have the current firmware version in each case (see the inverter product page at
www.SMA-Solar.com).
5.3.3 Operation of a PV system with third-party inverters
For the operation of the SunnyHomeManager in a system with third-party inverters, an SMAEnergyMeter as a PV
generation meter is required.
☐ The power output of the inverters from other manufacturers must be captured via a separate SMAEnergyMeter.
☐ The SMAEnergyMeter must be configured in SunnyPortal as a PV generation meter.
If third-party inverters are also used in the PV system, the SMAEnergyMeter handles the recording of the generated
PV energy. In hybrid systems with SMA inverters and inverters from other manufacturers, the generated energy of all
inverters is measured via the energy meter since it is used as the central PV generation meter. Upon registering and
configuring a PV generation meter in the SunnyHomeManager system, the SunnyHomeManager will receive the
power data of the SMA inverters on this PV generation meter.
Monitoring of the PV system and the dynamic limitation of the active power fed into the utility grid are not possible with
inverters from other manufacturers. In this case, verify whether operation of the PV system without dynamic active
power limitation is permitted in the given country, or whether dynamic active power limitation can be performed
independently by the inverter itself.
5.3.4 Components for the control of loads
At least one of the following compatible components must be present to control loads:
☐ Switching device, e.g. a radio-controlled socket, a relay or a Modbus device
☐ Device with EEBus or SEMP interface
Switching device
Devices that do not have a directly communicating data connection can be integrated into the energy management
system as an intermediate switch via radio-controlled sockets, relays or Modbus devices. The SunnyHomeManager
controls the switching device; the switching device can then switch the loads on and off via control signals from the
SunnyHomeManager. For example, the Modbus device MoxaE1214 offers the possibility to control a heat pump
via the relay output R0 (terminal 9 and 10).
At which times the SunnyHomeManager switches the switching device on or off automatically and without any further
manual operation depends on the configuration of the load and the current load planning configured in the
SunnyPortal: The SunnyHomeManager can measure the power consumption and length of the power consumption
of individual loads connected to a switching device and transmits these measured values to SunnyPortal. There, you
can control specific loads so that they are switched on if a lot of PV power is available, for example.
In addition, switching devices can be used purely for monitoring purposes, i.e. to measure the energy consumption of
individual loads.
Device with EEBus or SEMP interface
To control a load that communicates directly, this load must have an EEBus or SEMP interface that is compatible with
the SunnyHomeManager.
