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. SunnyPortal
powered by ennexOS 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 26 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, Great Britain, and
Australia.
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 residential installation cabinet in the area of the additional
applications intended for this as per VDE-AR-N 4100:2019-04 or the locally applicable installation
regulations.
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.
Statutory warranty
Use SMA products only in accordance with the information provided in the enclosed
documentation and with the locally applicable laws, regulations, standards and directives. Any
other application may cause personal injury or property damage.
Any use of the product other than that described in the Intended Use section does not qualify as the
intended use
The enclosed documentation is an integral part of this product. Keep the documentation in a
convenient, dry place for future reference and observe all instructions contained therein.

2 Safety SMA Solar Technology AG
Operating manualHM-20-ennexOS-BE-en-1014
This document does not replace any regional, state, provincial, federal or national laws, regulations
or standards that apply to the installation, electrical safety and use of the product. SMA Solar
Technology AG assumes no responsibility for the compliance or non-compliance with such laws or
codes in connection with the installation of the product.
2.2 IMPORTANT SAFETY INFORMATION
Keep the manual for future reference.
This section contains safety information that must be observed at all times when working.
The product has been designed and tested in accordance with international safety requirements. As
with all electrical or electronical devices, some residual risks remain despite careful construction. To
prevent personal injury and property damage and to ensure long-term operation of the product,
read this section carefully and observe all safety information at all times.
DANGER
Danger to life due to electric shock when live components or cables are
touched
High voltages are present in the conductive components or cables of the product. Touching live
parts and cables results in death or lethal injuries due to electric shock.
• Disconnect the product from voltage sources and make sure it cannot be reconnected
before carrying out any work on the product.
• Before carrying out any work on the product, disconnect the grid side from all voltage
sources using the installed disconnect switch.
• Ensure that the conductors to be connected are de-energized.
• Clean the product with a dry cloth only.
• Only use the product in a dry environment and keep it away from moisture.
• Install the product in the switch cabinet only and ensure that the connection areas for the
line conductors and the neutral conductor are behind a cover or have contact protection.
• Observe the prescribed minimum clearance between the network cable and live installation
components, or use suitable insulation.
DANGER
Danger to life due to electric shock if external disconnect switch is missing
High voltages are present in the conductive components. Touching live parts results in death or
lethal injuries due to electric shock.
• Install an external disconnect switch between the product and the grid-connection point. The
external disconnector must be close to the product and easily accessible.
• Before carrying out any work on the product, disconnect the grid side from all voltage
sources using the installed disconnect switch.

2 Safety
SMA Solar Technology AG
Operating manual HM-20-ennexOS-BE-en-10 15
DANGER
Danger to life due to electric shock in case of overvoltages and if surge
protection is missing
Overvoltages (e.g. in the event of a flash of lightning) can be further conducted into the building
and to other connected devices in the same network via the network cables or other data cables
if there is no surge protection. Touching live parts and cables results in death or lethal injuries due
to electric shock.
• Ensure that all devices in the same network are integrated in the existing overvoltage
protection.
WARNING
Danger of fire due to missing or incorrect fuse
If a fuse is missing or incorrect and a fault occurs, a fire may be caused. This can result in death
or serious injury.
• Protect the line conductors of the product with a fuse or a selective circuit breaker with max.
63A.
NOTICE
Manipulation of system data in networks
You can connect the supported SMA products to the Internet. When connected to the Internet,
there is a risk that unauthorized users can access and manipulate the data of your system.
• Set up a firewall.
• Close unnecessary network ports.
• If absolutely necessary, only enable remote access via a virtual private network (VPN).
• Do not use the port forwarding feature. This also applies to the used Modbus ports.
• Disconnect system components from other network components (network segmentation).
• Even if the product is used as energy and grid-supply meter, the system setup assistant in
SunnyPortal must be used and an administrator account created.
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. These operating activities, including data communication between PV system
operator/service personnel and data logger, inverter or additional equipment, can be accessed by
using local displays, keypads or using local access of the webserver of a device in the LAN of the
PV system or of the building.
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 powered by ennexOS)
• 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 powered by ennexOS 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 enables secure communication via the
internet.
You can find the current recommendations of SMA Solar Technology AG on the topic of cyber
security in the technical information "PUBLIC CYBER SECURITY - Guidelines for a Secure PV System
Communication" at www.SMA-Solar.com.

3 Applications
3.1 SunnyHomeManager as energy meter
The SunnyHomeManager detects energy flows in both directions and can be used as the
following applications:
• As a consumption meter
• As an energy meter for energy generators through, for example, continuous recording of the
energy generated by the PV system
• As an energy meter to capture the grid-supplied power and export via bidirectional
measurement at the point of interconnection
3.2 SunnyHomeManager in systems without self-
consumption
3.2.1 Monitoring System of the SunnyHomeManager in
Systems without Self-Consumption
The basic PV system status monitoring to confirm correct system performance analyzes all energy
flows and indicates, or evaluates, these. Disturbances are communicated at an early stage via
message. In this way, the product supports maximizing the power and profitability of PV systems,
extending the service life of the system, and minimizing downtimes.
3.2.2 Limiting of the Active Power Feed-In in Systems without
Self-Consumption
Local legal regulations, for example the Renewable Energy Sources Act (EEG) in Germany, can
call for permanent limiting of the active power feed-in for your PV system. This means limiting the
active power fed into the utility grid to a fixed value or a percentage of the installed nominal 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.
3.3 SunnyHomeManager in systems with self-
consumption
3.3.1 Information about 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.

3.3.2 Monitoring and prognosis
The energy management system can create a PV generation forecast based on the location-based
weather forecast. Furthermore, it is possible to create a load profile based on individual analysis of
time-dependent energy consumption:
The SunnyHomeManager makes recommendations for the judicious use of electrical energy. This
enables the switching on and off of household loads (e.g., home appliances, heating, heat pumps,
charging stations) in a targeted manner (see Section11, page50).
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.
3.3.3 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 automatically switches on home appliances that can be operated
flexibly when PV energy is available.
3.3.4 Optimized self-consumption through dynamic active
power limitation
Through forecast-based load control, the SunnyHomeManager ensures that even on sunny days,
surplus energy that had to be curtailed due to limiting of the active power is rarely lost.
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.
3.3.5 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.
3.3.6 Increased Self-Consumption and 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).
• 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
