2 Safety

SMA Solar Technology AG

Danger to life due to high voltages of the PV array

When exposed to sunlight, the PV array generates dangerous DC voltage which is present in the
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 uninsulated 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 Section10 "Disconnecting the Inverter from Voltage
Sources", page48).

Danger to life due to electric shock

Touching an ungrounded PV module or array frame can cause a fatal electric shock.

4.2 Interfaces and Functions

The inverter can be equipped or retrofitted with the following interfaces and functions:

BLUETOOTH

Via BLUETOOTH, the inverter can communicate with various BLUETOOTH devices (for information
on supported SMA products, see www.SMA-Solar.com).

Speedwire/Webconnect

SMA Speedwire/Webconnect is a type of communication based on the Ethernet standard. This
enables inverter-optimized 10/100Mbit data transmission between Speedwire devices in PV
systems and the software Sunny Explorer. The Webconnect function enables direct data
transmission between the inverters of a small-scale system and the Internet portal SunnyPortal
without any additional communication device and for a maximum of four inverters per SunnyPortal
system. In large-scale PV power plants, data transmission to the Internet portal Sunny Portal is
carried out via the SMA Cluster Controller. You can access your SunnyPortal system from any
computer with an Internet connection.

Operating ManualSTP15-17TL-10-BE-en-1014

SMA Solar Technology AG

SMA Speedwire/Webconnect enables, for PV systems operated in Italy, the connection to or
disconnection of the inverter from the utility grid and definition of the frequency limits to be used
with IEC61850-GOOSE messages.

SMA Speedwire/Webconnect can be retrofitted.

4 Product Description

RS485 interface

The inverter can communicate via cables with special SMA communication products via the RS485
interface (information on supported SMAproducts at www.SMA-Solar.com). The RS485 interface
can be retrofitted.

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.

SMA Power Control Module

The SMAPowerControlModule enables the inverter to implement grid management services and
is equipped with an additional multifunction relay (for information on installation and configuration,
see the installation manual of the SMAPowerControlModule). The SMAPowerControlModule
can be retrofitted.

Multifunction Relay

You can configure the multifunction relay for various operating modes. The multifunction relay is
used, for example, to switch fault indicators on or off (for information on installation and
configuration, see the installation manual of the multifunction relay). The multifunction relay can be
retrofitted.

SMAOptiTracGlobalPeak

SMAOptiTracGlobalPeak is an advancement of SMAOptiTrac 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 SMAOptiTracGlobalPeak, the inverter can detect the presence of 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.

String-failure detection

String-failure detection recognizes the failure of an individual string or substring. If an insulation
error occurs, string-failure detection disconnects the defective string from the inverter. This avoids
having to shut down the entire PV array. In order for the string-failure detection to be reliable,
identically aligned PV modules must be connected to both inputs of the inverter. String-failure
detection is deactivated by default and must be activated.

Surge Arrester Type II

The surge arresters monitor the PV modules and limit dangerous overvoltages. Surge arresters of
typeII can be retrofitted.

Operating Manual 15STP15-17TL-10-BE-en-10

4 Product Description

SMA Solar Technology AG

Electronic string fuse

The electronic string fuse protects the PV array against potential reverse currents. The electronic
string fuse recognizes DC cables that were connected with reverse polarity or defective PV modules
and short-circuits the PV array. In order for the electronic string fuse function to be reliable, the
connection of the PV array must be made when there is sufficient irradiation. If the input voltage is
less than 188V, the protective function of the electronic string fuse is not active when the
connection is made.

QonDemand24/7

The inverter can supply reactive power by means of QonDemand24/7 covering the entire unit
circle around the clock.

IntegratedPlantControl

The inverter can display the Q(V) characteristic curve specified by the grid operator by means of
IntegratedPlantControl without measuring on the grid-connection point. The inverter can
automatically compensate equipment installed between the inverter and the grid-connection point.

6.3 AC Connection

6.3.1 Requirements for the AC Connection

Cable requirements:

☐ External diameter: 14 mm to 25 mm
☐ Conductor cross-section: 1.5 mm² to 16 mm²
☐ Maximum conductor cross-section with bootlace ferrule: 10mm²

Operating Manual 25STP15-17TL-10-BE-en-10

6 Electrical Connection

SMA Solar Technology AG

☐ Insulation stripping length: 12 mm
☐ 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 "SunnyDesign" from software
version2.0 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 three-phase circuit

breaker. Make sure to observe the maximum permissible fuse protection (see Section11
"Technical Data", page50). 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 100mA 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 categoryIII or lower in accordance with
IEC60664-1. 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 categoryIV to overvoltage categoryIII are required (see the Technical
Information "Overvoltage Protection" at www.SMA-Solar.com).

Additional grounding:

Safety in accordance with IEC62109

The inverter is not equipped with a grounding conductor monitoring device. In order to
guarantee safety in accordance with IEC62109, you must take one of the following
measures:

• Connect a grounding conductor made of copper wire with a cross-section of at least
10mm² to the connecting terminal plate for the AC cable.

• Connect additional grounding with the same cross-section as the connected grounding
conductor to the connecting terminal plate for the AC cable (see Section6.3.3
"Connecting Additional Grounding", page28). This prevents touch current if the
grounding conductor at the connecting terminal plate for the AC cable fails.

Operating ManualSTP15-17TL-10-BE-en-1026

6 Electrical Connection

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 with the same cross­section as the connected grounding conductor to the connecting terminal plate for the AC
cable (see Section6.3.3, page28). This prevents touch current if the grounding
conductor at the connecting terminal plate for the AC cable fails.

6.3.2 Connecting the Inverter to the Utility Grid

☐ 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 from all three line conductors and secure against reconnection.

2. If the lower enclosure lid is mounted, loosen all screws of the lower enclosure lid using an
Allen key (AF3) and lift the enclosure lid from below and remove it.

3. Remove the adhesive tape from the enclosure opening for the AC cable.

4. Insert the cable gland from the outside into the
enclosure opening and tighten it from the inside
with the counter nut.

5. Route the AC cable into the inverter through the cable gland. If necessary, slightly loosen the
swivel nut of the cable gland.

6. Remove the sheath from the AC cable.

7. Shorten L1, L2, L3 and N by 5mm each.

8. Strip off the insulation of L1, L2, L3, N and PE by 12mm.

9. Push the safety levers of the AC connecting terminal plate right up to the stop.

10.

Risk of fire if two conductors are connected to one terminal

If you connect two conductors to a terminal, a fire can occur due to a bad electrical
connection.

• Never connect more than one conductor per terminal.

11.

Danger of crushing when locking levers snap shut

The locking levers close by snapping down fast and hard.

• Press the locking levers of the connecting terminal plate for the AC cable down with your
thumb only.

• Do not grip the entire connecting terminal plate for the AC cable.

• Do not place your fingers under the locking levers.

12. Connect PE, N, L1, L2 and L3 according to the labeling to the connecting terminal plate for the
AC cable and push the safety levers down. The direction of the rotating magnetic field of L1,
L2 and L3 is not relevant.

13. Make sure that all conductors are securely in place.

14. Tighten the swivel nut of the cable gland.

6.3.3 Connecting 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 connecting
terminal plate for the AC cable fails. The required clamping bracket, the screw and the conical
spring washer are part of the scope of delivery of the inverter.

Cable requirement:

☐ Grounding cable cross-section: max. 16mm²

Operating ManualSTP15-17TL-10-BE-en-1028

SMA Solar Technology AG

Procedure:

1. Strip the grounding cable insulation.

2. Lead the clamping bracket over the grounding
cable. Arrange the grounding cable on the left­hand side.

3. Screw the clamping bracket tight using the
M6x16 cylindrical screw and the conical spring
washer M6 (torque: 6Nm). The teeth of the
conical spring washer must face the clamping
bracket.

6.4 DC Connection

6 Electrical Connection

6.4.1 Requirements for the DC Connection

Requirements for the PV modules per input:

☐ All PV modules must be of the same type.
☐ All PV modules must be aligned and tilted identically.
☐ On the coldest day based on statistical records, the open-circuit voltage of the PV array must

never exceed the maximum input voltage of the inverter.

☐ The same number of series-connected PV modules must be connected to each string.
☐ The maximum input current per string must be maintained and must not exceed the through-

fault current of the DC connectors (see Section11 "Technical Data", page50).

☐ The thresholds for the input voltage and the input current of the inverter must be adhered to

(see Section11 "Technical Data", page50).

☐ The positive connection cables of the PV modules must be fitted with the positive DC

connectors (for information on assembling DC connectors, see the DC connector installation
manual).

☐ The negative connection cables of the PV modules must be fitted with the negative DC

connectors (for information on assembling DC connectors, see the DC connector installation
manual).

Operating Manual 29STP15-17TL-10-BE-en-10

6 Electrical Connection

SMA Solar Technology AG

Use of Y adapters for parallel connection of strings

The Y adapters must not be used to interrupt the DC circuit.

• Do not use the Y adapters in the immediate vicinity of the inverter. The adapters must not
be visible or freely accessible.

• In order to interrupt the DC circuit, always disconnect the inverter as described in this
document (see Section10, page48).

6.4.2 Connecting the PV Array

Risk of fire due to electric arc when thresholds on the DC input are exceeded

The electronic string fuse recognizes when the maximum short-circuit current is exceeded and
short-circuits the PV array. This can cause an electric arc and thus a risk of fire.

• Ensure that the thresholds for the input voltage, the input current and the short-circuit current
of the inverter are adhered to.

Damage to the DC connectors due the use of contact cleaner of other cleaning agents

Some contact cleaners or other cleaning agents may contain substances that decompose the
plastic of the DC connectors.

• Do not use contact cleaners or other cleaning agents for cleaning the DC connectors.

Limitation of the electronic string fuse by using string connection boxes

When using string connection boxes, the functionality of the electronic string fuse may be
limited.

Procedure:

1. Ensure that the circuit breaker is switched off from all three line conductors and that it cannot
be reconnected.

2. Ensure that there is no ground fault in the PV array (see service manual at www.SMA­Solar.com).

3. Securely plug in the ESS. The ESS must be aligned parallel to and flush with the enclosure. If
the ESS is plugged in when connecting the DC connectors, the protective function of the
electronic string fuse can be activated.

Operating ManualSTP15-17TL-10-BE-en-1030

6 Electrical Connection

4.

Risk of fire due to reverse currents not being detected

The electronic string fuse monitors the PV array and protects it against dangerous reverse
currents which can cause a fire. In order to activate the electronic string fuse, you must observe
the following during DC connection:

• When connecting more than two strings, the first string must be connected to input B of
the inverter. This activates the string fuse.

• All strings must be clearly assigned to the correct DC input. Do not cross-wire or combine
the strings.

5. Check whether the DC connectors have the correct polarity.
If the DC connector is equipped with a DC cable of the wrong polarity, the DC connector must

be assembled again. The DC cable must always have the same polarity as the DC connector.

6. If there are more than two strings, connect the first assembled DC connector to input B. This
activates the string fuse.

☑ The green LED is flashing or glowing, no acoustic signal sounds and no error message is

displayed. The string fuse is activated and all remaining DC connectors can be
connected.

✖ The display does not show any data after a waiting period of at least 60seconds and no

acoustic signal sounds?
The inverter is probably defective.

• Ensure that the DC input voltage is at least 188V.

• Ensure that the DC connectors are not connected with reverse polarity.

• If the DC input voltage is sufficient and the DC connectors are connected correctly,
contact Service (see Section13, page56).

✖ An acoustic signal sounds and an error message with the event number 4001 appears in

the display?
The inverter short-circuits the PV array to avoid reverse currents through individual strings.

The PV array and the inverter are in a safe state.

• Do not remove the ESS and/or the DC connector under any circumstances. This
prevents an electric arc from forming which can cause injuries and a fire.

• Stop working on the inverter and wait until dark and until the acoustic signal no
longer sounds.

• If you would like to leave the PV system to continue work when it is dark, set up
protection against contact (e.g. a fence) and protect the inverter against penetrating
moisture (e.g. with tarp).

• Only remove the ESS and all DC connectors and correct the connection once it is
dark.

✖ An acoustic signal sounds and an error message with the event number 6313 or 8201

appears in the display?

• Contact Service (see Section13, page56).

7 Commissioning

SMA Solar Technology AG

7 Commissioning

7.1 Commissioning Procedure

Before you can commission the inverter, you must check various settings and make changes if
necessary. This section describes the procedure and gives an overview of the steps, which must
always be performed in the prescribed sequence.

Procedure See

1. Check which country data set the inverter is set to. Supplementary sheet with
the default settings, type la­bel or display

2. If the country data set is not set correctly for your country

or your purpose, adjust to the required country data set
and the corresponding display language within the first
ten feed-in hours via the rotary switches in the inverter.

3. If the inverter is to communicate with several BLUETOOTH

devices, or if BLUETOOTH is not to be used as a type of
communication, set the NetID.

4. Commission the inverter. Section7.4, page37

Section7.2, page34

Section7.3, page35

7.2 Configuring the Country Data Set

A display language is assigned to every country data set. Set the country data set appropriate for
your country or purpose, with the corresponding display language, within the first ten feed-in hours
via the rotary switches in the inverter. After the first ten feed-in hours, the country data set can only
be changed by means of a communication product.

If the display language of the country data set does not match the required language, you can
change it after commissioning (see Section8.2 "Changing the Display Language", page39).

The country data set must be set correctly.

If you select a country data set which is not valid for your country and purpose, it can cause a
disturbance in the PV system and lead to problems with the grid operator. When selecting the
country data set, you must always observe the locally applicable standards and directives as
well as the properties of the PV system (e.g. PV system size, grid-connection point).

• If you are not sure which country data set is valid for your country or purpose, contact
your grid operator for information on which country data set is to be configured.

Operating ManualSTP15-17TL-10-BE-en-1034

SMA Solar Technology AG

Country data set for operation with external decoupling protection

When operating the PV system with external decoupling protection, the inverter has the
additional country data set Medium-Voltage Directive (Germany) or MVtgDirective. This
country data set allows you to extend the operating range of the inverter for voltage and
frequency. This country data set should only be selected if the PV system is disconnected via
external decoupling.

• If the country data set for operation is set with external decoupling protection, only
operate the inverter with an external three-phase decoupling protection. Without external
three‑phase decoupling protection, the inverter will not disconnect from the utility grid
when the country-specific standard requirement is exceeded.

Procedure:

1. Determine the rotary switch position for your country and purpose. Call up the Technical
Information "Overview of the Rotary Switch Settings" at www.SMA-Solar.com.

2.

Danger to life due to high voltages

• Ensure that the inverter is disconnected from all voltage sources and that the enclosure lid
is removed (see Section10, page48).

3. Set the rotary switches A and B to the required
position using a flat-blade screwdriver (blade
width: 2.5mm).

7 Commissioning

☑ The inverter will adopt the setting after commissioning. This can take up to five minutes.

7.3 Setting the NetID

By default, the NetID is set to 1 for all SMAinverters and SMAcommunication products with
BLUETOOTH. If your PV system consists of an inverter and a maximum of one further BLUETOOTH
device (e.g. computer with BLUETOOTH interface or SMAcommunication product), you can leave
the NetID set to 1.

Operating Manual 35STP15-17TL-10-BE-en-10

7 Commissioning

SMA Solar Technology AG

You must change the NetID in the following cases:

• If your PV system consists of one inverter and two other BLUETOOTH devices (e.g. computer
with BLUETOOTH interface and SMA communication product) or of multiple inverters with
BLUETOOTH, you must change the NetID of your PV system. This will enable communication
with multiple BLUETOOTH devices.

• If another PV system with BLUETOOTH is located within 500m of your PV system, you must
change the NetID of your PV system. This will help keep both PV systems separate.

• If you do not wish to communicate via BLUETOOTH, deactivate the BLUETOOTH
communication on your inverter. This will protect your PV system from unauthorized access.

All BLUETOOTH devices in a PV system must have the same NetID. You can set a new NetID in the
inverter by means of the rotary switch C.

10 Disconnecting the Inverter from Voltage Sources

Prior to performing any work on the inverter, always disconnect it from all voltage sources as
described in this section. Always adhere to the prescribed sequence.

Destruction of the measuring device due to overvoltage

• Only use measuring devices with a DC input voltage range of 1,000 V or higher.

Procedure:

1. Disconnect the circuit breaker from all three line conductors and secure against reconnection.

2. If the multifunction relay is used, switch off any supply voltage to the load.

3. Test whether there is an acoustic signal.

If an acoustic signals sounds and the display shows an error message that prohibits
disconnecting the ESS, wait until dark. The ESS can only be disconnected once it is dark.

If no acoustic signal sounds and the display does not show an error message, remove the ESS.

4. Wait until the LEDs and the display have gone out.

5. Remove all six screws from the lower enclosure

lid using an Allen key (AF3).

6. Flip the lower enclosure lid up and remove it.

7.

Risk of burns when touching the DC protective cover

The DC protective cover can get hot during operation.

• Do not touch the DC protective cover.

8. Use an appropriate measuring device to ensure that no voltage is present at the AC

connecting terminal plate between L1 and N, L2 and N, and L3 and N. Insert the test probe
into each round opening of the terminal.

10 Disconnecting the Inverter from Voltage Sources

9. Use an appropriate measuring device to ensure that no voltage is present at the AC

connecting terminal plate between L1 and PE, L2 and PE, and L3 and PE. Insert the test
probe into each round opening of the terminal.

10. If you are using the multifunction relay, ensure that no voltage is present between any of the
terminals on the multifunction relay and PE on the AC connecting terminal plate.

11. Use a current clamp to ensure that no current is present in the DC cables.

12. Release and remove all DC connectors. To do this, insert a flat-blade screwdriver or an angled
screwdriver (blade width: 3.5mm) into one of the side slots and pull the DC connectors
straight out. Do not pull on the cable.

13.

Danger to life due to high voltages in the inverter

The capacitors in the inverter take 20minutes to discharge.

• Wait 20minutes before opening the upper enclosure lid.

• Do not open the DC protective cover.

14.

Damage to the inverter due to electrostatic discharge

Touching electronic components can cause damage to or destroy the inverter through
electrostatic discharge.

• Ground yourself before touching any component.
