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 data and purchased electricity 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 switch is required in the battery-backup system. In the event of grid
failure, the automatic transfer switch 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.
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.

Operating manualSBSxx-10-BE-en-1018
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 and a standard switch to the inverter. You can connect
a load with a maximum of 16A and 230/240V to the outlet. The load is supplied with energy
form the battery during grid failure. The switch is used to activate and deactivate secure power
supply operation.
The secure power supply operation is not automatically activated in the event of a grid failure,
neither is it automatically deactivated once the utility grid is available again. If the utility grid fails,
the load supply must be activated 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 deactivated manually by switching the switch off.
During active secure power supply operation, the inverter is disconnected from the electricity 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
does not take place automatically. Once the battery is sufficiently charged again and the load can
be supplied, the secure power supply operation must be restarted.
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 a stable energy supply
The secure power supply operation and the battery-backup operation may not be used for
loads that require a stable 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 a stable energy supply for reliable
operation.
Battery-backup function
The inverter is equipped with a battery-backup function. The battery-backup function is deactivated
by default and must be activated via the user interface. The battery-backup function can only be
activated if the inverter is operated in a battery-backup system with an automatic transfer switch.
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
loading of the battery is ensured by the existing PV system. As soon as the utility grid is available

again, the battery-backup operation is deactivated 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 activated in the event of a grid failure, and must also be deactivated
again once the utility grid is available.
An updated list of automatic transfer switches approved by SMA Solar Technology AG is available
at www.SMA-Solar.com.
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 a stable energy supply
The secure power supply operation and the battery-backup operation may not be used for
loads that require a stable 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 a stable 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.
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.

5.1 Requirements for Mounting
Requirements for the mounting location:
WARNING
Danger to life due to fire or explosion
Despite careful construction, electrical devices can cause fires.
• Do not mount the product in areas containing highly flammable materials or gases.
• Do not mount the product in potentially explosive atmospheres.
☐ The mounting location must be inaccessible to children.
☐ A solid support surface must be available for mounting, e.g. concrete or masonry. When
mounted on drywall or similar materials, the inverter emits audible vibrations during operation
which could be perceived as annoying.
☐ The mounting location must be suitable for the weight and dimensions of the inverter (see
Section13 "Technical Data", page119).
☐ The mounting location must not be exposed to direct solar irradiation. If the inverter is exposed
to direct solar irradiation, the exterior plastic parts might age prematurely and overheating
might occur. When becoming too hot, the inverter reduces its power output to avoid
overheating.
☐ The mounting location should be freely and safely accessible at all times without the need for
any auxiliary equipment (such as scaffolding or lifting platforms). Non-fulfillment of these
criteria may restrict servicing.
☐ To ensure optimum operation, the ambient temperature should be between -25°C and
+45°C.
☐ Climatic conditions must be met (see Section13 "Technical Data", page119).
Permitted and prohibited mounting positions:
☐ The inverter must only be mounted in one of the permitted positions. This will ensure that no
moisture can penetrate the inverter.
☐ The inverter should be mounted in such a way that the LED signals can be read without
difficulty.

Recommended Clearances:
If you maintain the recommended clearances, adequate heat dissipation will be ensured. Thus, you
will prevent power reduction due to excessive temperature.
☐ Maintain the recommended clearances to walls as well as to other inverters or objects.
☐ If multiple inverters are mounted in areas with high ambient temperatures, increase the
clearances between the inverters and ensure sufficient fresh-air supply.

5.2 Mounting the Inverter
Additionally required mounting material (not included in the scope of delivery):
☐ Three screws suitable for the support surface (diameter: 8mm)
☐ Three washers suitable for the screws
☐ Where necessary, 3 screw anchors suitable for the support surface and the screws
☐ To secure the inverter against theft: one padlock suitable for outdoor use
Padlock dimensions:
• Diameter of the shackle: 8mm to 10mm
• Width of the shackle (inner dimension): 30mm to 40mm
• Height of the shackle (inner dimension): 30mm to 40mm

CAUTION
Risk of injury when lifting the inverter, or if it is dropped
The inverter weighs 26kg. There is risk of injury if the inverter is lifted incorrectly or dropped
while being transported or when attaching it to or removing it from the wall mounting bracket.
• Transport and lift the inverter carefully.
The Connection Unit and Power Unit can be disconnected from one another
to make mounting easier
If the local conditions make it difficult to mount the entire inverter, you can disconnect the
Connection Unit and Power Unit from each other if the ambient temperature is at least 0°C
and there is no frost. This way, you can transport each enclosure part and also attach to the
wall mounting bracket individually. Then, during assembly, both enclosure parts must be joined
again. A detailed description for how to disconnect the Connection Unit and Power Unit from
each other and to individually mount them to the wall mounting bracket can be found on the
Internet under www.SMA-Solar.com.
Procedure:
1.
CAUTION
Risk of injury due to damaged cables
There may be power cables or other supply lines (e.g. gas or water) routed in the wall.
• Ensure that no lines are laid in the wall which could be damaged when drilling holes.
2. Align the wall mounting bracket horizontally on the
wall and use it to mark the position of the drill holes.
Here, use at least one hole each, to the right and
left, and the hole at the bottom center.
3. Set the wall mounting bracket aside and drill the marked holes.
4. Insert screw anchors into the drill holes if the support surface requires them.
5. Secure the wall mounting bracket horizontally using screws and washers.

6. Hook the inverter into the wall mounting bracket.
Here, the lugs on the rear side of the Power Unit
must be hooked into the upper recesses and the lugs
in the Connection Unit into the lower recesses in the
wall mounting bracket.
TOP
7. Check whether the inverter is securely in place.
If the Connection Unit can be moved forward, the lugs on the rear side of the Connection Unit
are not hooked into the lower recesses in the wall mounting bracket. Remove the inverter from
the wall mounting bracket and hook it in again.
Once the Connection Unit cannot be moved forward, the inverter is securely in place.
8. Secure the inverter to the wall mounting bracket. To
do this, insert the screw M5x60 through the hole on
the left side of the Power Unit using a Torx
screwdriver (TX25) and screw it into the thread
(torque: 1.7Nm ± 0.3Nm).
9. If the inverter is to be protected against theft, attach a padlock:
• To do this, guide the shackle of the padlock
through the provided hole on the left side of the
Power Unit and close the shackle.
• Keep the key of the padlock in a safe place.
