4 Product Overview
SMA Solar Technology AG
4 Product Overview
4.1 Product Description
The SunnyBoyStorage uses the connected battery for the intermediate storage of excess PV
energy in the SMAFlexibleStorageSystem. For this purpose, the SunnyBoyStorage receives the
feed-in and purchased energy data from the energy meter. This data is used by the
SunnyBoyStorage to control the charging and discharging of the battery.
The use of an automatic transfer switching device is required in the battery-backup system. In the
event of grid failure, the automatic transfer switching device disconnects the PV system, loads and
the SunnyBoyStorage from the utility grid and creates a battery-backup grid. The battery-backup
grid supplies loads that should continue to be supplied with electricity in the event of grid failure. In
the event of grid failure, the SunnyBoyStorage supplies the loads with energy after a short
switching time. The PV system supplies additional energy that can be used to supply the loads and
charge the battery.
The use of an automatic transfer switching device is not required in limited battery-backup systems.
To build a limited battery-backup system, you must attach an outlet and a switch to the inverter. You
can connect a load to the outlet, which should continue to be supplied with power from the battery
in the event of grid failure. The secure power supply operation is not automatically enabled in the
event of a grid failure, neither is it automatically disabled once the utility grid is available again.
During secure power supply operation, the load can only be supplied with energy as long as there
is stored energy available in the battery.
Secure power supply operation in FlexibleStorageSystems with backup
power supply not possible
If the inverter is used in a battery-backup system and connected with an automatic transfer
switch, the secure power supply operation is not available.

4 Product Overview
Grid management services
The product is equipped with service functions for grid management.
Depending on the requirements of the grid operator, you can activate and configure the functions
(e.g. active power limitation) via operating parameters.
Secure power supply operation
In case of a grid failure, the secure power supply operation supplies the loads with energy from the
battery. You can connect a standard outlet (230V) and a standard switch to the inverter. You can
connect a load with a maximum of 16A and 230/240V to the emergency power outlet. The load
is supplied with energy from the battery during grid failure. The switch is used to enable and
disable secure power supply operation.
The secure power supply operation is not automatically enabled in the event of a grid failure,
neither is it automatically disabled once the utility grid is available again. If the utility grid fails, the
load supply must be enabled manually by activating the switch. The inverter automatically regulates
the energy supply of the outlet after activating the switch. When the utility grid is available again
and the load can be supplied by this again, the secure power supply operation must be disabled
manually by switching the switch off.
During active secure power supply operation, the inverter is disconnected from the building's main
electrical system and does not therefore feed into the utility grid. During secure power supply
operation, the load can only be supplied with energy as long as there is stored energy available in
the battery. If there is insufficient energy available from the battery, the secure power supply
operation remains active, even if the utility grid is available again. Switching over to supplying the
load from the utility grid is not carried out automatically.
Secure power supply operation in FlexibleStorageSystems with backup
power supply not possible
If the inverter is used in a battery-backup system and connected with an automatic transfer
switch, the secure power supply operation is not available.
Do not connect any loads that require an uninterrupted energy supply
The secure power supply operation and the battery-backup operation may not be used for
loads that require a uninterrupted energy supply. The energy that is available during the
secure power supply operation or battery-backup operation depends on the battery capacity
available and the state of charge of the battery (SOC).
• Do not connect loads if they are dependent on an uninterrupted energy supply for
reliable operation.

Battery-backup function
The inverter is equipped with a battery-backup function. The battery-backup function is disabled by
default and must be enabled via the user interface. The battery-backup function can only be
enabled if the inverter is operated in a battery-backup system with an automatic transfer switching
device. If the system is retrofitted with an automatic transfer switching device, the battery
configuration must be reset and carried out once again. Then the battery-backup system must be
configured. The configuration is carried out via the installation assistant on the user interface of the
battery inverter.
The battery-backup function ensures that the inverter forms a battery-backup grid that uses energy
from the battery and the PV system to supply the household grid in the event of a utility grid failure.
When the battery-backup operation is activated, the automatic transfer switch disconnects the PV
system and the household grid from the utility grid in the event of a grid failure, and connects these
to the battery-backup grid. After a short switch-over time, the battery-backup grid and loads
connected can be supplied by the battery and supplemented with energy from the PV system. The
charging of the battery is ensured by the existing PV system during battery-backup operation. The
charging process of the battery (initiated by the PV system) can be deactivated via a certain
parameter during battery-backup operation. As soon as the utility grid is available again, the
battery-backup operation is disabled automatically and the loads are supplied with energy from the
utility grid. If the automatic battery-backup operation is not set, the battery-backup operation must
be manually enabled in the event of a grid failure, and must also be disabled again once the utility
grid is available (information in terms of switching operations of the automatic transfer switch and
procedures during grid failure and grid reconnection see planning guidelines
"SMAFLEXIBLESTORAGESYSTEM with Battery-Backup Function").
When the utility grid is down and the battery fully discharged, there is, in the beginning, not enough
power available to create a stable battery-backup grid. In this case, the battery must be charged by
the PV system. The battery inverter is able to create a stable battery-backup grid only when enough
power is available in the battery. To use battery charging power from the PV system, the battery
inverter has to create a stand-alone grid. For this purpose, the battery inverter requires energy from
the battery reserve. If enough PV power is available, the PV inverters start automatically and the
battery is charged with energy from the PV system. The battery is charged with energy until the
battery inverter is able to provide a battery-backup grid. By setting parameters, it is possible to
define up to which state of charge the battery is charged and discharged. If not enough PV energy
is available to start the PV inverters, the stand-alone grid breaks down. Two hours later, the battery
inverter tries to start the PV inverter again to charge the battery with energy from the PV system. If
the battery inverter still fails to create a stand-alone grid after several attempts due to insufficient PV
energy, the battery inverter and battery switch to sleep mode. In this case, a manual black start is
required to switch the battery inverter and battery from sleep mode back to operation.

4 Product Overview
Do not connect any loads that require an uninterrupted energy supply
The secure power supply operation and the battery-backup operation may not be used for
loads that require a uninterrupted energy supply. The energy that is available during the
secure power supply operation or battery-backup operation depends on the battery capacity
available and the state of charge of the battery (SOC).
• Do not connect loads if they are dependent on an uninterrupted energy supply for
reliable operation.
Black start function
The inverter has a black start function and an auxiliary battery that provides energy for the black
start. In battery-backup systems, you have the possibility to install a standard switch for black
starting the inverter and battery. The black-start switch is used to start the battery-backup operation
manually in the event of grid failure if the battery and inverter are in sleep mode and, therefore, are
unable to provide energy. When the black-start switch is switched on manually, the energy from the
auxiliary battery is made available in order to automatically switch the battery and therefore also
the inverter from sleep mode to operation in order that the inverter can make energy available from
the battery. You can stop the battery-backup operation by switching it off manually. To enable the
black-start function, at least one battery must be connected to input A.
Multi-battery device
The product is equipped with the multi-battery function as standard from firmware version
1.50.10.R. The multi-battery function enables to charge and discharge several batteries of the same
or different type. If the system is extended by one or several batteries or one battery is replaced,
the battery configuration must be reset and carried out again. The configuration is carried out via
the installation assistant on the user interface of the battery inverter. An overview of batteries
approved by SMA Solar Technology AG and their possible combinations is available at
www.SMA-Solar.com.
All-pole sensitive residual-current monitoring unit
The all-pole sensitive residual-current monitoring unit detects alternating and direct differential
currents. In single-phase and three-phase inverters, the integrated differential current sensor detects
the current difference between the neutral conductor and the line conductor(s). If the current
difference increases suddenly, the inverter disconnects from the utility grid.
SMA Smart Connected
SMA Smart Connected is the free monitoring of the inverter via the SMA SunnyPortal. Thanks to
SMA Smart Connected, the PV system operator and qualified person will be informed automatically
and proactively about inverter events that occur.
SMA Smart Connected is activated during registration in SunnyPortal. In order to use SMA Smart
Connected, it is necessary that the inverter is permanently connected to SunnyPortal and the data
of the PV system operator and qualified person is stored in SunnyPortal and up-to-date.

Time-of-Use
With the "Time-of-Use" function, you can adjust the charging behavior of the battery to your
electricity tariff. Energy bills are thus reduced and electricity at lower cost can be used. You can
determine in which time range the battery with a specified charging power is operated. At specific
times, this is mostly useful when the battery's state of charge has to take on a certain value or the
tariff situation makes the charging more attractive, regardless of the power at the grid-connection
point. The charging parameters set in the power profile are only limited by the state of charge
(SOC). At times when the "Time-of-Use" function is not enabled, the battery is charged
correspondent to the increased self-consumption for the entire system. The "Time-of-Use" function is
disabled by default and must be enabled by creating power profiles.
Peak load shaving
With the "Peak Load Shaving" function, you can optimize the behavior of the battery inverter with
respect to the power exchange at the grid-connection point. This is mostly useful when a higher
supply of energy would lead to a higher electricity cost. With the "Peak Load Shaving" function,
certain grid-exchange power outputs to which the battery inverter is adjusted depending on its
power and battery capacity available can be set. Power peaks can thus be avoided.
You can configure times and setpoints for the power drawn at the grid-connection point. When the
loads require additional energy, the battery is discharged and the maximum value is kept constant
at the grid-connection point. This is based on the prerequisite that the battery is sufficiently charged.
At times when the "Peak Load Shaving" function is not activated, the battery is charged or
discharged correspondent to the increased self-consumption for the entire system. The "Peak Load
Shaving" function is deactivated by default and must be activated by creating power profiles.
Frequency Shift Power Control
If PV inverters are connected on the AC side during battery-backup operation, the battery inverter
must be able to limit their output power. This limitation becomes necessary when, for example, the
battery inverter's battery is fully charged and the power available from the PV system exceeds the
power requirement of the connected loads.
To prevent excess energy from overcharging the battery, the battery inverter automatically detects
the problem and changes the frequency at the AC output. This frequency adjustment is analyzed by
the PV inverter. As soon as the power frequency of the battery-backup grid increases beyond the
value specified in f Start Delta, the PV inverter limits its output power accordingly.

The frequency shift power control is enabled by default. No additional settings must be carried out.
It must be ensured that the connected PV inverters limit their power at the AC output via the battery
inverter due to changes in frequency. The frequency-dependent active power limitation P(f) must be
set in the PV inverter.
