DC conductors and the live components of the inverter. Touching the DC conductors or the live
components can lead to lethal electric shocks. If you disconnect the DC connectors from the
inverter under load, an electric arc may occur leading to electric shock and burns.
• Do not touch non-insulated cable ends.
• Do not touch the DC conductors.
• Do not touch any live components of the inverter.
• Have the inverter mounted, installed and commissioned only by qualified persons with the
appropriate skills.
• If an error occurs, have it rectified by qualified persons only.
• Prior to performing any work on the inverter, disconnect it from all voltage sources as
described in this document (see Section10 "Disconnecting the Inverter from Voltage
Sources", page50).
Danger to life due to high voltages in the inverter
Touching live components within the inverter can lead to lethal electric shocks. Some components
also require at least five minutes to discharge after the inverter has been disconnected from
voltage sources.
• Do not open the inverter.
Danger to life due to electric shock
Touching an ungrounded PV module or array frame can cause a lethal electric shock.
• Connect and ground the PV modules, array frame and electrically conductive surfaces so

Web server with user interface for configuration
The inverter is equipped as standard with an integrated web server that enables configuration of
the inverter via an individual user interface. The inverter user interface can be called up directly via
the web browser in a computer, tablet PC or smartphone so long as there is a WLAN or Ethernet
connection (see Section8 "Using the Inverter User Interface", page34).
SMA Speedwire
The inverter is equipped with SMA Speedwire as standard. SMA Speedwire is a type of
communication based on the Ethernet standard. This enables inverter-optimized 10/100Mbit data
transmission between Speedwire devices in PV systems and the inverter user interface.
Webconnect
The inverter is equipped with a Webconnect function as standard. The Webconnect function
enables direct data transmission between the inverters of a small-scale system and the Internet
portal SunnyPortal without any additional communication device and for a maximum of four
inverters per SunnyPortal system. In large-scale PV power plants, data transmission between
inverters and the Internet portal SunnyPortal is carried out via the SunnyHomeManager. You can
access your SunnyPortal system from any computer with an Internet connection.
Webconnect enables - for PV systems operated in Italy - the connection or disconnection of the
inverter to or from the utility grid and the specifying of the frequency limits to be used via
IEC61850-GOOSE messages.
WLAN
The inverter is equipped with a WLAN interface as standard. The inverter is delivered with the
WLAN interface activated as standard. If you do not want to use WLAN, you can deactivate the
WLAN interface (see Section9.17 "Switching WLAN Off", page48). In addition, the inverter has
a WPS (WiFi Protected Setup) function. The WPS function connects the inverter automatically with
an end device (e.g. smartphone, tablet PC or computer). You can activate the WPS function by
tapping on the enclosure lid twice in quick succession. The open interface will then be signalized
via the rapid flashing of the blue LED on the inverter.

Grid Management Services
The inverter 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.
SMAOptiTracGlobalPeak
SMAOptiTracGlobalPeak is an advancement of SMAOptiTrac and allows the operating point of
the inverter to follow the optimal operating point of the PV array (MPP) precisely at all times. In
addition, with the aid of SMAOptiTracGlobalPeak, the inverter detects several maximum power
points in the available operating range, such as may occur particularly with partially shaded
strings. SMA OptiTrac Global Peak is enabled by default.
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.
Connection of the SMAEnergyMeter
If an SMAEnergyMeter is installed in the PV system, the inverter can receive data on the
household energy consumption directly from this.

Cable requirements:
☐ External diameter: 5 mm to 13 mm
☐ Conductor cross-section: 1.5mm² to 4mm²
☐ Insulation stripping length: 15 mm
Operating Manual21SB15-25-BE-en-10
Page 22
6 Electrical Connection
SMA Solar Technology AG
☐ Sheath stripping length: 70mm
☐ The cable must be dimensioned in accordance with the local and national directives for the
dimensioning of cables. The requirements for the minimum wire size derive from these
directives. Examples of factors influencing cable dimensioning are: nominal AC current, type of
cable, routing method, cable bundling, ambient temperature and maximum desired line losses
(for calculation of line losses, see the design software "SunnyDesign" from software
version2.0 at www.SMA-Solar.com).
Load-break switch and cable protection:
Damage to the inverter due to the use of screw-type fuses as load-break switches
Screw-type fuses (e.g. DIAZED fuse or NEOZED fuse) are not load-break switches.
• Do not use screw-type fuses as load-break switches.
• Use a load-break switch or circuit breaker as a load disconnection unit (for information and
design examples, see the Technical Information "Circuit Breaker" at www.SMA-Solar.com).
☐ In PV systems with multiple inverters, protect each inverter with a separate circuit breaker.
Make sure to observe the maximum permissible fuse protection (see Section11 "Technical
Data", page52). This will prevent residual voltage being present at the corresponding cable
after disconnection.
☐ Loads installed between the inverter and the circuit breaker must be fused separately.
Residual-current monitoring unit:
☐ If an external residual-current device is required, install a residual-current device which trips at
a residual current of 100mA or higher (for details on selecting a residual-current device, see
the Technical Information "Criteria for Selecting a Residual-Current Device" at www.SMASolar.com).
Overvoltage category:
The inverter can be used in grids of overvoltage categoryIII or lower in accordance with
IEC60664-1. That means that the inverter can be permanently connected to the grid-connection
point of a building. In case of installations with long outdoor cabling routes, additional measures to
reduce overvoltage categoryIV to overvoltage categoryIII are required (see the Technical
Information "Overvoltage Protection" at www.SMA-Solar.com).
Grounding conductor monitoring:
The inverter is equipped with a grounding conductor monitoring device. This grounding conductor
monitoring device detects when there is no grounding conductor connected and disconnects the
inverter from the utility grid if this is the case. Depending on the installation site and grid
configuration, it may be advisable to deactivate the grounding conductor monitoring. This is
necessary, for example, in an IT system if there is no neutral conductor present and you intend to
install the inverter between two line conductors. If you are uncertain about this, contact your grid
operator or SMA Solar Technology AG.
☐ Grounding conductor monitoring must be deactivated after initial start-up depending on the
grid configuration (see Section9.5, page43).

SMA Solar Technology AG
6 Electrical Connection
Safety in accordance with IEC62109 when the grounding conductor monitoring is
deactivated
In order to guarantee safety in accordance with IEC62109 when the grounding conductor
monitoring is deactivated, carry out one of the following measures:
• Connect an additional grounding that has at least the same cross-section as the
connected grounding conductor to the connecting terminal plate for the AC cable (see
Section6.3.3, page25). This prevents touch current if the grounding conductor at the
connecting terminal plate for the AC cable fails.
Connection of additional grounding
In some countries, additional grounding is generally required. In each case, observe the
locally applicable regulations.
• If additional grounding is required, connect an additional grounding that has at least the
same cross-section as the connected grounding conductor to the connecting terminal
plate for the AC cable (see Section6.3.3, page25). This prevents touch current if the
grounding conductor at the connecting terminal plate for the AC cable fails.
6.3.2Connecting the Inverter to the Utility Grid
Requirements:
☐ Only the AC connector supplied may be used.
☐ The connection requirements of the grid operator must be met.
☐ The grid voltage must be in the permissible range. The exact operating range of the inverter is
specified in the operating parameters.
Procedure:
1. Disconnect the circuit breaker and secure it against reconnection.
2. Unscrew the swivel nut from the cable gland for
the AC connection.
3. Thread the swivel nut over the AC cable.
4. Thread the AC cable through the cable gland.

• If the external diameter of the cable is
between 5mm and 7mm, thread the cable
through the cable gland directly.
• If the external diameter of the cable is
between 8mm and 13mm, first remove the
inner sealing ring from the cable gland and
then thread the cable through the cable
gland. When doing so, ensure that the
outer sealing ring is positioned correctly in
the cable gland.
5. Dismantle 70mm of the AC cable.
6. Shorten both L and N by 5mm respectively, in order that the grounding conductor is the last
to become detached in the event of tension.
7. Strip 15 mm of the insulation of L, N and the grounding conductor.
8. Connect L, N and the grounding conductor to
the connecting terminal plate of the supplied AC
plug in accordance with the labeling. When
doing so, ensure that the conductors are
plugged completely into the terminal up to the
insulation.
Tip: To detach the conductors, plug a flat-blade
screwdriver (blade width: 3mm) into the
rectangular openings positioned behind them.
9. Make sure that all conductors are securely in place.

14. Attach the connection cap to the inverter using
the three screws and a Torx screwdriver (TX20)
(torque: 3.5Nm).
6 Electrical Connection
15. Tighten the swivel nut hand-tight.
6.3.3Connecting Additional Grounding
If additional grounding or equipotential bonding is required locally, you can connect additional
grounding to the inverter. This prevents touch current if the grounding conductor at the terminal for
the AC cable fails.
The required clamping bracket, the cylindrical screw M5x16, the washer and the spring lock
washer are part of the scope of delivery of the inverter.
Cable requirements:
Use of fine-stranded conductors
You can use an inflexible or a flexible, fine-stranded conductor.
• When using a fine-stranded conductor, it has to be double crimped by a ring terminal lug.
Make sure that no insulated conductor is visible when pulling or bending. This will ensure
sufficient strain relief by means of the ring terminal lug.
☐ Grounding cable cross-section: max. 10mm²

☑ The installation assistant dialog opens.
SMA Solar Technology AG
9.3Starting the Self-Test (For Italy Only)
The self-test is only required for inverters to be commissioned in Italy. The Italian standard requires
that all inverters feeding into the utility grid are equipped with a self-test function in accordance with
CEI0-21. During the self-test, the inverter will consecutively check the reaction times for
overvoltage, undervoltage, maximum frequency and minimum frequency.
The self-test changes the upper and lower disconnection values for each protective function on a
linear basis for frequency monitoring and voltage monitoring. As soon as the measured value
exceeds the permitted disconnection threshold, the inverter disconnects from the utility grid. In this
way, the inverter determines the reaction time and checks itself.
After the self-test has been completed, the inverter automatically switches back to feed-in operation,
resets the original disconnection conditions and connects to the utility grid. The test takes
approximately threeminutes.
Requirements:
☐ The country data set of the inverter must be set to CEI 0-21 internal.

9.16Switching the Dynamic Power Display Off
As standard, the inverter signals its power dynamically via the pulsing of the green LED. When
doing so, the LED flashes on and off uniformly or is permanently lit at full power. The various
gradations are related here to the set active power limit of the inverter. If this display is not desired,
switch this function off in accordance with the following procedure. Once this has been done, the
green LED is only lit permanently to signalize feed-in operation.
The basic procedure for changing operating parameters is explained in another section (see
Section9.14 "Changing Operating Parameters", page46).
Procedure:
• In the parameter group Device > Operation, select the parameter Dynamic power
display via green LED and set this to Off.
9.17Switching WLAN Off
The inverter is equipped with an activated WLAN interface as standard. If you do not want to use
WLAN, you can switch the WLAN function off in accordance with the following procedure. In
doing so, you can switch the WLAN direct connection and the WLAN connection in the local
network on or off independently of each other. If you would like to switch the WLAN function off
completely, you must switch off both the WLAN direct connection and the WLAN connection in the
local network.
The basic procedure for changing operating parameters is explained in another section (see
Section9.14 "Changing Operating Parameters", page46).
Switching on the WLAN function only possible via Ethernet connection
If you switch off both the WLAN function for the WLAN direct connection and for the WLAN
connection in the local network, access to the inverter user interface and therefore reactivation
of the WLAN interface is only possible via an Ethernet connection.
Procedure:
• To switch off the WLAN direct connection, select the parameter Soft-access-point is turned
on and set this to No.
• To switch off the WLAN connection in the local network, select the parameter WLAN is
turned on and set this to No.
9.18Switching WLAN On
If you have switched the WLAN function for direct connection or for connection in the local network
off, you can switch the WLAN function back on in accordance with the following procedure. In
doing so, you can switch the WLAN direct connection and the WLAN connection in the local
network on independently of each other.
The basic procedure for changing operating parameters is explained in another section (see
Section9.14 "Changing Operating Parameters", page46).
Requirement:
☐ If the WLAN function was previously switched off completely, the inverter must be connected
to a computer or router via Ethernet.
