2.1 Appropriate Usage
The Sunny Tripower is a PV inverter which converts the direct current of a PV array into alternating
current and feeds this into the electricity grid.
Principle of a PV system with the Sunny Tripower
String connections Sunny Tripower 10000TL and 12000TL
The Sunny Tripower 10000TL and 12000TL only have four string connections at input A.
The Sunny Tripower must only be operated with PV arrays of protection class II, in accordance with
IEC 61730, application class A. Do not connect any energy sources other than PV modules to the
Sunny Tripower.
Capacitive leakage currents
PV modules with large capacities relative to earth, such as thin-film PV modules with cells on a
metal substrate, may only be used if their coupling capacity does not exceed 2.55 μF.
During feed-in operation, a leakage current flows from the cells to earth, the size of which
depends on the manner in which the PV modules are installed (e.g. foil on metal roof) and on
the weather (rain, snow). This "normal" leakage current must not exceed 90 mA, as otherwise
the inverter would automatically disconnect from the electricity grid as a protective measure.
For further information on this subject, see the technical information "Capacitive Leakage
Currents" at www.SMA-Solar.com.
When designing the PV system, ensure that the permitted operating range of all components is
complied with at all times. The free design programme "Sunny Design", version 2.0 or higher
(see www.SMA-Solar.com/SunnyDesign), will assist you in this. The manufacturer of the PV modules
must have approved the PV modules for use with the Sunny Tripower. You must also ensure that all
measures recommended by the module manufacturer for the long-term maintenance of the module
properties are taken (see also technical information "Module Technology" at www.SMA-Solar.com).
Do not use the Sunny Tripower for purposes other than those described here. Alternative uses,
modifications to the Sunny Tripower or the installation of components not expressly recommended or
sold by SMA Solar Technology AG void the warranty claims and operation permission.

3 Product Description
The Sunny Tripower is a multi-string inverter which converts the direct current of a PV array into
alternating current. To do this, the Sunny Tripower is equipped with two separate MPP trackers which
can be connected to the different PV modules. The inverter performs three-phase feed-in of electricity
into the electricity grid. Cooling is effected via the OptiCool active cooling system.
In addition, Sunny Tripower is equipped with the features described below.
3.1 Bluetooth
The inverter is equipped with a serial Bluetooth interface and can communicate with special
SMA communication products and other inverters (for information on supported products,
see www.SMA-Solar.com).
If you wou ld like t o co mmunica te v ia Bluetooth, you can protect the inverter with one system password
for the user and one system password for the installer. All inverters are delivered with a standard
system password for the user (0000) and a standard system password for the installer (1111).
To protect the system from unauthorised access, you must change the system passwords using
Sunny Explorer (for information on changing the system password, refer to the Sunny Explorer help).
If you do not want to communicate via Bluetooth, deactivate Bluetooth communication
(see Section6.6.1 "Bluetooth", page52).
3.2 Communication Interface
The inverter can optionally be fitted with an extra communication interface (e.g., RS485).
This communication interface enables the inverter to communicate with special SMA communication
products or other inverters (for information on supported products, see www.SMA-Solar.com).
The interface can either be retrofitted or installed at the factory according to a specific order.
You can only set the operating parameters of the inverter via SMA communication products.
You can set the country data set of the inverter via the two rotary switches in the inverter only prior to
commissioning or within the first ten operating hours.
Depending on the type of communication, RS485 or Bluetooth or Speedwire, the parameters and
messages are displayed differently in the communication products.
Example: How the country data set parameter is displayed
• For communication with RS485: CntrySet parameter
•If you are using Bluetooth or Speedwire: parameter Set country standard

SMA Solar Technology AG 3 Product Description
3.3 Multi-Function Interface
The inverter is equipped with a slot for multi-function interfaces. This slot is designed to connect a
simple multi-function relay or an SMA Power Control Module. The interface can either be retrofitted
or installed at the factory according to a specific order.
Multi-Function Relay
You can configure the multi-function relay for various operating modes. The multi-function relay is
us ed, for exa mpl e, t o switch fau lt i ndi cat ors on o r of f (f or i nformation on installation and configuration,
see installation manual of the multi-function relay).
Error message required by technical standards
In some countries the indication of errors is mandatory in order to comply with the requirements
of a technical standard, e.g. IEC 62109-2.
To meet the requirements of IEC 62109-2, you must either connect an indicator to the
multi-function relay to report an error or register the inverter in the Sunny Portal. If you register
the inverter in the Sunny Portal, you can activate the error alarm (for information on error alarm
via Sunny Portal, see the Sunny Portal user manual at www.SMA-Solar.com).
SMA Power Control Module
The SMA Power Control Module enables the inverter to implement grid management services and is
equipped with an additional multi-function relay (for information on installation and configuration,
see installation manual of the SMA Power Control Module).
3.4 SMA OptiTrac Global Peak
SMA OptiTrac Global Peak is a more advanced form of the MPP tracking tool SMA OptiTrac.
MPP tracking is a feature that determines the highest usable power in the PV system at any given time.
The power generated by the PV array depends on the level of solar irradiation and the temperature
of the PV modules. As a result, the optimum operating point for maximum power (MPP) changes
constantly throughout the day.
SMA OptiTrac ensures that the operating point of the inverter always coincides exactly with the MPP.
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 PV strings. By this means, almost the entire available power of partially shaded PV strings can
be fed into the electricity grid.
SMA OptiTrac Global Peak is deactivated by default. In the case of partially shaded PV modules,
it should be activated and set via a communication product (see Section8.2 "Activating and Setting
SMA OptiTrac Global Peak", page59).

3.5 Surge Arrester Type II
Along with the thermally monitored varistors which are integrated as standard, the Sunny Tripower is
equipped with module slots for the additional installation of surge arresters of Type II. If the modules
are connected, they will be monitored. If a module has tripped, a warning is issued via the display or
external communication (e.g. Sunny WebBox or Sunny Explorer). This makes it easy to integrate the
Sunny Tripower into a lightning protection concept. The required modules are available as retrofit kits
for input A or input A+B.
3.6 Intelligent String Failure Detection
The Sunny Tripower is equipped with a system that recognises the total failure of individual strings or
partial strings (see the diagram below). With a PV module current of approx. 1 A, monitoring of up to
six partial strings per string input is possible. The prerequisite for the reliable functioning of the intelligent
string failure detection is an identical alignment of the connected PV array at input A and input B.
For the learning phase, the Sunny Tripower needs approximately 14 days at moderate irradiation after
successful activation. One advantage of this system is that its auto-adaptive function completely
eliminates the necessity of any configuration. In the event of a string failure, a warning message is issued
on the display or via external communication (e.g. Sunny WebBox or Sunny Explorer). Note that
extreme shading and snow-covered PV modules trip warning messages.
16 STP10-17TL-IA-en-32 Installation Manual
Page 17
SMA Solar Technology AG 3 Product Description
3.7 Electronic String Fuse
The Sunny Tripower is equipped with an electronic string fuse. This prevents dangerous reverse
currents in the PV array and thus plays a key role in fire prevention. Reverse currents can occur as a
result of reverse poling during installation or module defects during operation. The electronic string
fuse recognises these defects and shorts the PV array. This prevents the occurrence of reverse currents
and thus safeguards both the PV system and the Sunny Tripower. An advantage of this method is that
conventional fuses at the DC inputs are not necessary. The electronic solution is entirely
maintenance-free and does not require any dimensioning.
In order to make optimum use of this function, particular care must be taken during commissioning
(see Section6.4 "Connecting the PV Array (DC)", page35). The Sunny Tripower signals
dangerous conditions by beeping and issuing warnings in the display or external communication
(see Section12.1 "Sunny Tripower is Beeping", page82). If electrical installation takes place under
conditions of insufficient irradiation (PV voltage less than 188 V), the Sunny Tripower will not have
power supply which means that the protective functions described above will not be active during
installation.
3.8 Grid Management

5.1 Safety
Danger to life due to fire or explosion
Despite careful construction, electrical devices can cause fires.
• Do not mount the inverter on flammable construction materials.
• Do not mount the inverter in areas where highly flammable materials are stored.
• Do not mount the inverter in a potentially explosive atmosphere.
Risk of injury due to the heavy weight of the inverter (approximately 65 kg)
• Take the weight of the inverter into account during transport.
• Select a suitable mounting location and mounting surface.
• When mounting the rear panel, use fastening material suitable for the mounting surface.
• Two people are needed to mount the inverter.
Risk of burns due to hot enclosure parts
• Mount the inverter in such a way that it cannot be touched inadvertently.

max. 15°
5.2 Selecting the Mounting Location
Take the following requirements into consideration when selecting the mounting location:
• The mounting method and location must be suitable for the weight and size of the inverter
(see Section14 "Technical Data", page92).
• Mount on a solid surface.
• The mounting location must be clear and safely accessible at all times without the use of
additional aids such as scaffolding or lifting platforms. If this is not the case, service work may
be restricted.
• Mount vertically or tilted backwards by max. 15°.
• The connection area must point downwards.
• Never mount the device with a forward tilt.
• Never mount the device with a sideways tilt.
• Do not mount horizontally.
• Mount the inverter at eye level. Given the weight of the device, this will facilitate disassembly if
service work is necessary.
• The ambient temperature should be below 40°C to ensure optimum operation.
• Do not expose the inverter to direct solar irradiation as this could cause power derating due to
overheating.
• In order to avoid audible vibrations in living areas, do not mount the unit on plasterboard walls
or similar. When in operation, the inverter emits noise which may be perceived as annoying in
living areas.
Installation Manual STP10-17TL-IA-en-32 21
Page 22
5 Mounting SMA Solar Technology AG
• Observe the recommended clearances to walls,
other inverters or other objects, as shown in the
diagram. That ensures sufficient heat dissipation
and gives you enough space to unplug the
Electronic Solar Switch.
• If multiple inverters are mounted in areas with high
ambient temperatures, allow more than the
recommended clearances between the inverters
and ensure an adequate fresh-air supply.
This prevents a reduction in inverter power as a
result of high temperatures (details on temperature
derating can be found in the Technical Information
"Temperature Derating" at www.SMA-Solar.com).

6.3 Connecting the Electricity Grid (AC)
6.3.1 Conditions for the AC Connection
You must comply with the connection requirements of your network operator.
Residual Current Device
The inverter is equipped with an integrated all-pole-sensitive residual-current monitoring unit.
The inverter can automatically differentiate between residual currents and normal leading leakage
currents.
If an external RCD or residual-current device is strictly required, you must use a switch that trips at a
residual current of 100 mA or higher.
You will find further information for using an RCD in the technical information "Criteria for Selecting
an RCD" at www.SMA-Solar.com.
Overvoltage Category
The inverter can be deployed in grids of installation category III or lower, as defined under
IEC 60664-1. This means that it can be permanently connected at the grid-connection point in a
building. In installations involving long outdoor cable routes, additional overvoltage-reducing
measures must be taken so that the overvoltage category is reduced from IV to III (for further
information, see the Technical Information "Overvoltage Protection" at www.SMA-Solar.com).
Cable Dimensioning
The cable must be dimensioned in accordance with any local and national directives on cable
dimensions which specify requirements for the minimum conductor cross-section. Cable dimensioning
factors are e.g.: nominal AC current, type of cable, type of routing, cable bundling, ambient
temperature and maximum specified line losses (for calculation of line losses, see design software
"Sunny Design" with software version 2.0 or higher at www.SMA-Solar.com).

B Conductor
cross-section
1.5 mm² to 16 mm², with bootlace ferrule
maximum 10 mm²
C Stripping length approximately 12 mm
The PE wire must be 5 mm longer than the L and N wires.
Connection of a Second Protective Conductor
In some installation countries, a second protective conductor is required in order to prevent a contact
current in the event of failure of the original protective conductor.
For installation countries falling within the scope of validity of the IEC standard 62109, the following
requirements are applicable:
• Installation of protective conductor at the AC terminal with a conductor cross-section of at least
10 mm² Cu.
or
• Installation of a second protective conductor at the earth terminal with the same cross-section as
the original protective conductor at the AC terminal (see Section6.3.3 "Connecting the Second
Protective Conductor", page34).
You must always observe the applicable regulations in the country of installation.
30 STP10-17TL-IA-en-32 Installation Manual
Page 31
SMA Solar Technology AG 6 Electrical Connection
Load Disconnection Unit
You must install a separate miniature circuit-breaker for each inverter in order to ensure that the
inverter can be securely disconnected under load. You should use a three-pole miniature
circuit-breaker. If you are using a single-pole miniature circuit-breaker, a residual voltage from the
inverter may be present on the relevant cable after disconnection (maximum permissible fuse
protection (see Section14 "Technical Data", page92)).
Danger to life due to fire
When more than one inverter is connected in parallel to the same miniature circuit-breaker, the
protective function of the miniature circuit-breaker is no longer guaranteed. This could result in a
cable fire or destruction of the inverter.
• Never connect several inverters to a single miniature circuit-breaker.
• Observe the maximum permissible fuse protection of the inverter when selecting the miniature
circuit-breaker.
Danger to life due to fire
When a generator (inverter) and a load are connected to the same miniature circuit-breaker, the
protective function of the miniature circuit-breaker is no longer guaranteed. The currents from the
inverter and the electricity grid can accumulate to form overcurrents which are not detected by the
miniature circuit-breaker.
• Never connect loads between the inverter and the miniature circuit-breaker without fuse
protection.
• Always protect loads separately.
Damage to the inverter by use of screw-type fuses as switch-disconnectors
A screw-type fuse, e.g. DIAZED fuse or NEOZED fuse, is not a switch-disconnector and thus
may not be used as a load disconnection unit. A screw-type fuse only acts as cable protection.
If the inverter is disconnected under load using a screw-type fuse, the inverter may be damaged.
• Use only a switch-disconnector or a miniature circuit-breaker as a load disconnection unit.

6.4 Connecting the PV Array (DC)
6.4.1 Conditions for DC Connection
The inverter has two input areas "A" and "B", each with its own MPP tracker.
Up to four strings (Sunny Tripower 10000TL / 12000TL) or five strings (Sunny Tripower 15000TL /
17000TL) can be connected at input area A. One string can be connected at input area B.
• For input area A, the PV modules must meet the following requirements:
– same type
– same number of in-series-connected PV modules
– identical alignment
– identical tilt
• For the activation of the intelligent string failure detection, the PV modules at input A and B must
be identically aligned.
• The connecting cables of the PV modules must be equipped with connectors. The connectors
required for DC connection are included in the scope of delivery.

12000TL 1,000 V 22.0 A / 11.0 A 33 A / 12.5 A
15000TL 1,000 V 33.0 A / 11.0 A 40 A / 12.5 A
17000TL 1,000 V 33.0 A / 11.0 A 40 A / 12.5 A
• 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.
Risk of fire as a result of overcurrent on the string input
Destruction of the inverter
Since the electronic string fuse shorts the PV array in the event of a fault, the thresholds for the
maximum short-circuit current per string input given in the table above must not be exceeded.
If a string input is overloaded, it can result in an electric arc and hence a risk of fire.
• Make sure that the thresholds specified in the table above are not exceeded.
• Check whether the short-circuit currents of the connected PV modules are in compliance with
the thresholds given in the table above.
36 STP10-17TL-IA-en-32 Installation Manual
Page 37
SMA Solar Technology AG 6 Electrical Connection
Function of the Electronic String Fuse
The electronic string fuse prevents reverse currents in the PV array. Activation of the electronic string
fuse is only possible if the following conditions are met:
• During installation, the DC input voltage must be at least 188 V (see Section14 "Technical
Data", page92) in order to activate the protective function of the integrated electronic string
fuse, otherwise, a reversed polarity at the DC connection or a defective string will not be
recognised by the inverter.
Risk of fire in the PV array due to non-recognition of reverse currents
The integrated electronic string fuse monitors the PV array and protec ts it ag ainst dangerou s rever se
currents. In order to activate the electronic string fuse, you must observe the following during
connection of the strings:
• If more than two strings are connected to the inverter, ALWAYS connect the first string to
input B. If no string is connected at input B, the string fuse will not be active.
• Each string must be clearly assigned to the correct string input. D o not cr oss-wire or bun dle the
string cables. See the diagram in Section 6.4.1 for the correct assignment of the strings.
Use of external string collection boxes
If string collection boxes are used, the functionality of the electronic string fuse may be limited.
6.4.2 Assembling the DC Connectors
For connection to the inverter, all connection cables of the PV modules must be equipped with the
DC connectors provided.
Assemble the DC connectors as follows. Be sure to observe the correct polarity. The DC connectors
are marked with the symbols "+" and " − ".

6.4.4 Connecting the PV Array (DC)
Danger to life due to high voltages in the inverter
• Before connecting the PV array, ensure that the AC miniature circuit-breaker is switched off for
all three phase conductors.
Risk of electric arc if the DC connectors are pulled out while the Sunny Tripower is
beeping
The integrated electronic string fuse monitors the PV array. In case of incorrect installation
(e.g. reverse polarity) or a faulty string, the electronic string fuse short-circuits the PV array and the
Sunny Tripower starts to beep.
•Do NOT pull the DC connector out as this could trip an electric arc.
•Do NOT pull out the Electronic Solar Switch as otherwise the entire reverse current will flow
through the defective string which could result in a fire.
• Further procedure (see Section12.1 "Sunny Tripower is Beeping", page82).
Destruction of the inverter due to overvoltage
If the voltage of the PV modules exceeds the maximum input voltage of the inverter, it could be
destroyed by overvoltage. This will void all warranty claims.
• Do not connect any strings to the inverter which have an open-circuit voltage greater than the
maximum input voltage of the inverter.
•Check the system design.
Excessive voltages can destroy the multimeter
• Only use multimeters with a DC input voltage range up to at least 1,000 V.
40 STP10-17TL-IA-en-32 Installation Manual
Page 41
SMA Solar Technology AG 6 Electrical Connection
1. Check the connection cables of the PV modules for
correct polarity and make sure that the maximum
input voltage of the inverter is not exceeded.
At an ambient temperature over 10°C, the
open-circuit voltage of the PV modules should not
exceed 90% of the maximum input voltage of the
inverter. If this is not the case, review the system
design and the PV module circuitry.
Otherwise, the maximum inverter input voltage may be exceeded at low ambient temperatures.
2. Check strings for earth faults (see Section12.2 "Checking the PV Array for Earth Faults",
page83).
3. Check the Electronic Solar Switch for wear, as
described in Section 10.3. Providing it is in perfect
condition, plug the Electronic Solar Switch in right

The inverter can be configured for various countries. This is carried out via the two rotary switches in
the inverter prior to commissioning, or by configuring the "CntrySet" or "Set country standard"
parameter via a communication product (e.g. Sunny WebBox or Sunny Explorer) once you have
commissioned the inverter.
The switch position 0/0 indicates the state upon delivery. The country settings were preset at the
factory via a communication product if you ordered the inverter with specific country settings. In this
case, you will not be able to recognise the current setting by the switch position. If changes are made
via the rotary switches or via a communication product, the default grid parameters are overwritten.
They cannot be restored, and must be re-entered via a communication product. The display language
ca n be cha nge d at any tim e us ing the rota ry s wit che s, i nde pen dent of the grid parameters. This means
that the default grid parameters remain unchanged, but the display messages are shown in the set
language. For devices ordered without any specified country of installation, the standard setting is
"VDE0126-1-1" and the language is German.
Changes will be accepted immediately after switching the miniature circuit-breaker on. If a
non-programmed switch setting is selected, the inverter issues an error message on the display and
the last valid setting is retained.

SMA Grid Guard Protected Country Data Sets
In some countries, the local connection conditions demand a mechanism which prevents the feed-in
parameters from being changed. Therefore, some country data sets are protected and can only be
unlocked with a personal access code, the SMA Grid Guard code.
SMA Grid Guard protected country data sets are automatically blocked for ten feed-in hours after
commissioning, or after the last alteration. If the country data set is changed after these ten feed-in
hours, the inverter will not accept the changes and display the error message "Grid parameter
locked". If, however, a later change to the country data set only relates to a change of the display
language via the rotary switches in the inverter, this change is immediately applied.
It is also p ossible to conf igure country data s ets (parameter "CntrySet" or "Set country standard"), and
to lock or unlock these manually via a communication product. To lock a data set, enter the digit
sequence "54321" instead of the password in the SMA Grid Guard code field. The data set can only
be unlocked by entering a personal, ten-digit SMA Grid Guard code which is valid for a maximum
of ten feed-in hours. The application form for the personal access code is available at
www.SMA-Solar.com in the "Certificate" category of the respective inverter. The language can be
configured without a password, regardless of the country data set.
Changing parameters in SMA Grid Guard protected country data sets
If the para meter s withi n protec ted cou ntry da ta sets are chan ged, t hes e ar e no long er p rot ect ed
and instead of the standard, "ADJ" or "Special setting" is displayed. In this case, a change to
parameters is not locked automatically after ten feed-in hours, but has to be locked manually.
To manually lock the parameters, set the SMA Grid Guard Code to "54321".
Further information on parameter settings
You will find information on making adjustments and changing parameters in the user manual
for your software.
The last change (executed via rotary switch or communication product) is always verified and
activated if applicable. Consequently, the switch position may not necessarily show the actual country
setting.

6.5.1 Checking the Country Standard
Check whether the inverter is set to the country of installation.
Before commissioning:
• Check that the country standard of the inverter is correct by comparing the default settings of
the inverter listed on the supplementary sheet provided.
After commissioning:
• Check that the country standard is correct by checking the display message during
(re-)commissioning (see Section7 "Commissioning", page56).
or
• Check that the country standard is correct using the "SMA grid guard" measuring channel via
a communication product.
Display language
Once you have set the country standard, you can always set the display language later using
rotary switch B. However, you have to then set rotary switch A to "0" in order to keep the
country data set.
The settings of each country data set are specified in the operating parameters. The parameters can
be read out using a communication product. The description of the operating parameters is available
at www.SMA-Solar.com in the category "Technical Description" of the respective inverter.

6.5.2 Extension of the Deactivation Limits
The deactivation criteria (voltage, frequency) are specified by the country parameters.
Sunny Tripower inverters have the additional country data set "MVtgDirective". This parameter
expands the deactivation limits of the inverter for voltage and frequency to a maximum/minimum.
This country setting may only be selected if the system or the inverter is operated with external
three-phase decoupling protection, which will automatically disconnect the inverter from the electricity
grid if non-permissible voltage and frequency values occur. Device protection is still guaranteed.
Danger to life due to electric shock if external decoupling protection is missing
With the country setting "MVtgDirective", the inverter may only be operated with an external
three-phase decoupling protection device which complies with the country-specific requirements.
Without such external decoupling protection, the inverter will not disconnect from the electricity grid
when the standard requirement is exceeded.
• Install external three-phase decoupling protection.

6.6 Communication
6.6.1 Bluetooth
Communication via Bluetooth with a communication product is activated by default. Networking with
other inverters via Bluetooth is deactivated by default.
The following setting options are possible via a rotary switch:
Switch position
(NetID)
0Off
1 Communication via Bluetooth with communication product possible,
2 to F Networking with other inverters
In order to restrict communication via Bluetooth between the inverters of your system and those
of neighbouring systems, you can assign an individual NetID to the inverters of your system
(switch position 2 to F). However, this is only necessary if neighbouring systems are situated
within a radius of 500 m.
All inverters in your system must have the same NetID in order to be detected by your communication
product.
System password for user and installer
If you are using Bluetooth communication, you can protect the inverter with a system password
for the user and a system password for the installer. All inverters are delivered with the same
default system password. To protect the system from unauthorised access, you must change
system passwords using a communication product.
If you are not using Bluetooth communication, deactivate it. This will protect your system from
unauthorised access.
Changing the system time
If communication is effected via Bluetooth and Sunny Explorer, you must change the system
time (date and time) via a communication product after commissioning. This will prevent
disturbances when retrieving saved events.

You will also need the installer password to access the installer mode.
1. Enter the installer password.
2. Set the parameters "CoolSys.FanTst" or "Fan test" to "On" in the installer mode.
3. Check the air flow in both fans.
The inverter takes cooling air in from underneath on the left side and blows it out again through
the ventilation grids at the top. Listen for any unusual noise, which could indicate incorrect
installation or a fault in the fans.
4. After the test, set the parameter "CoolSys.FanTst" or "Fan test" back to the "Off" position.
☑ The fan test is now complete.

10.3 Checking the Electronic Solar Switch (ESS) for Wear
Check the Electronic Solar Switch for wear before plugging it in.
To do this, check whether the metal tongues (A) inside the plug display any brown discolouration.
If the metal tongues are discoloured or burnt right through (B), the Electronic Solar Switch can no
longer perform reliable disconnection of the DC side.
You must replace the handle of the Electronic Solar Switch before restarting the inverter.
You can obtain replacement handles for the Electronic Solar Switch from your specialist dealer
(see Section15 "Accessories", page110).

12.2 Checking the PV Array for Earth Faults
If the inverter displays event numbers "3501", "3601" or "3701", there is a high probability of an
earth fault in the PV array.
Check the strings for earth faults as described below:
1. Disconnect the inverter (see Section9 "Disconnecting the Inverter from Voltage Sources",
page61).
Danger to life due to live PV array
• Only touch the cables of the PV array by their insulation.
• Do not connect strings with earth faults to the inverter.
Excessive voltages can destroy the multimeter
• Only use multimeters with a DC input voltage range up to at least 1,000 V.
2. Measure the voltages between the positive pole of
each string and the earth potential (PE).
3. Measure the voltages between the negative pole of
each string and the earth potential (PE).
4. Measure the voltages between the positive and
negative poles of each string.
Installation Manual STP10-17TL-IA-en-32 83

12 Troubleshooting SMA Solar Technology AG
☑ An earth fault is present if the measured voltages are stable and the sum of the voltages of
the positive pole against earth potential and the negative pole against earth potential of a
string is approximately equal to the voltage between the positive and negative poles.
Result Measure
☑ You have detected an earth fault. • The installer of the PV array must remedy
the earth fault in the affected string.
You can determine the location of the earth
fault as described below.
• Do not reconnect the faulty string.
• Restart the inverter (see Section7
"Commissioning", page56).
☑You have not detected any earth fault. It is likely that one of the thermally monitored
varistors is defective.
• Check varistors (see Section12.3
"Checking the Function of the Varistors",
page85).
Location of the Earth Fault
The approximate location of the earth fault can be calculated from the ratio of the voltages
measured between plus and earth potential and minus and earth potential.
Example:
In this case, the earth fault is between the second and third PV modules.
☑ The earth fault check is now complete.

SMA Solar Technology AG 12 Troubleshooting
12.3 Checking the Function of the Varistors
If the inverter displays event number "7401", one of the varistors is probably defective.
Varistors are wear parts. Their functional efficiency diminishes with age or following repeated
responses as a result of overvoltages. It is therefore possible that one of the thermally monitored
varistors has lost its protective function.
Check the varistors as described below:
1. Disconnect the inverter (see Section9 "Disconnecting the Inverter from Voltage Sources",
page61).
Danger to life due to high voltages in the inverter
Death from electric shock
There is residual voltage in the inverter. The inverter takes 20 minutes to discharge.
• Wait 20 minutes before you open the upper enclosure lid or the DC lid.
Risk of burns due to hot components inside the inverter
• Wait until the components inside the inverter have cooled down.
2. Release the captive screws of the DC lid on the
left-hand side of the connection area.
3. Lift the DC lid up and off.

4. Remove all varistors by pulling them upwards.
If you have not received an insertion tool for
operating the terminals with the replacement
varistors, contact SMA Solar Technology AG.
5. Use a multimeter to check each varistor for a
conductive connection between terminals 2 and 3.
Result Measure
☑There is a conductive
connection.
Presumably there is a different error in the inverter.
• Proceed to step 8.
• Contact the SMA Service Line (see Section16 "Contact",
page111)
☑There is no conductive
connection.
The respective varistor is defective and must be replaced.
Varistor failure is due to influences which affect all varistors
similarly (temperature, age, induced overvoltages).
SMA Solar Technology AG recommends replacing all varistors.
The varistors are specially manufac tured fo r use in t he i nverter and
are not commercially available. You will need to order
replacement varistors directly from SMA Solar Technology AG
(see Section15 "Accessories", page110). Only use original
varistors that are sold by SMA Solar Technology AG.
• To replace the varistors, proceed to step 6.
Destruction of the inverter due to overvoltage
If varistors are missing, the inverter is no longer protected against overvoltages.
• Replacement varistors should be obtained as soon as possible.
• In PV systems with a high risk of overvoltages, never operate the inverter without varistors.

6. Insert an insertion tool into the openings of the
terminal contacts.
7. Insert new varistors into the slots by pushing them
down into the slots (as shown in the adjacent
diagram).
Make sure that the labelling is pointing to the front,
i.e. towards the insertion tool.
8. Dock the DC lid an at angle and then push on.
The captive screws must protrude.
9. Pre-screw all four screws of the DC lid and then
tighten them (torque: 3.5 Nm).
10. Restart the inverter (see Section7 "Commissioning", page56).
☑ The varistors have now been replaced and the inverter is back in operation.

12 Troubleshooting SMA Solar Technology AG
12.4 Replacing Surge Arresters Type II
If the inverter is displaying event number "8301" or "8302", presumably at least one surge arrester
is defective.
Surge arresters are wear parts. Their functional efficiency diminishes with age or following repeated
responses as a result of overvoltages. It is therefore possible that one of the surge arresters has lost its
protective function.
SMA Solar Technology AG therefore recommends replacing all surge arresters, since the failure of
one surge arrester is usually due to influences which affect all surge arresters in the same manner
(temperature, age, induced overvoltages). You will find the order numbers for both retrofit kits
(one for input A and one for input B) in Section 15.
Replace the surge arresters as described below:
1. Disconnect the inverter (see Section9 "Disconnecting the Inverter from Voltage Sources",
page61).
Danger to life due to high voltages in the inverter
Death from electric shock
There is residual voltage in the inverter. The inverter takes 20 minutes to discharge.
• Wait 20 minutes before you open the upper enclosure lid or the DC lid.
2. Release the captive screws of the DC lid on the
left-hand side of the connection area.
3. Lift the DC lid up and off.

4. Rem ove all sur ge a rre ste rs f rom t he s lot s. T o do thi s,
compress the grooved areas on either side.
☑ If a green strip is visible in the window (A),
the surge arrester is in perfect working order.
☑ If a red strip is visible in the window (A),
the surge arrester is defective.
5. Install new surge arresters (see Section6.7 "Retrofitting a Surge Arrester Type II", page53).

13 Decommissioning SMA Solar Technology AG
13 Decommissioning
13.1 Dismantling the Inverter
1. Disconnect the inverter (see Section9 "Disconnecting the Inverter from Voltage Sources",
page61).
2. Remove any connected communication cables from the inverter.
Risk of burns due to hot enclosure parts
• Wait 30 minutes for the enclosure to cool down before disassembling.
3. Screw off all projecting cable glands.
4. If necessary, open the anti-theft lock.
5. Lift the inverter off the rear panel and unscrew and remove rear panel as necessary.
13.2 Replacing the Enclosure Lid
In the event of a fault, your inverter may need to be replaced. If this is the case, you will receive a
replacement device fitted with transport lids.
Danger to life due to electric shock
During operation, there are high voltages present in the inverter.
• Do not operate the inverter without the upper and lower enclosure lid in place.
Dismantling Surge Arresters Type II
If you have retrofitted your inverters with surge arresters Type II, they must be dismantled before
returning the inverter to SMA Solar Technology AG (see Section12.4 "Replacing Surge
Arresters Type II", page88).
Prior to returning your inverter to SMA Solar Technology AG, you will need to replace the upper and
lower enclosure lids with the corresponding transport lids.
Danger to life due to high voltages in the inverter
Death from electric shock
After disconnecting the inverter, there is residual voltage in the inverter. The inverter takes 20 minutes
to discharge.
• Wait 20 minutes before you open the upper enclosure lid or the DC lid.
90 STP10-17TL-IA-en-32 Installation Manual
Page 91
SMA Solar Technology AG 13 Decommissioning
1. Dismantle the inverter (see Section13.1 "Dismantling the Inverter", page90).
2. Release all the screws on the upper enclosure lid
and remove it by pulling it towards you.
3. Do the same with the transport lid of the
replacement device.
4. Pre-screw the transport lid of the replacement
device with the six enclosure lid screws and
corresponding conical spring washers to your
original inverter and then screw down tight in the
sequence shown on the right (torque: 6.0 Nm).
The toothing of the conical spring washers must
point towards the enclosure lid. This ensures proper
earthing of the enclosure lid.
The scope of delivery of the inverter includes a
spare screw and conical spring washer.
5. Screw the lower enclosure lid down tight.
☑ The original inverter is now ready for return shipment to SMA Solar Technology AG.
6. Now mount the upper enclosure lid from the original inverter onto the replacement device in the
same manner.
7. Mount the replacement device (see Section5.3 "Mounting the Inverter with Rear Panel",
page23) and connect it (see Section6 "Electrical Connection", page27).
13.3 Packing the Inverter
• If the original packaging is available, the inverter should be packed in its original packaging
and secured with tension straps.
• If the original packaging is not available, use a cardboard box suitable for the weight and size
of the inverter.
13.4 Storing the Inverter
Store the inverter in a dry place where the ambient temperature is always between −25°C and +60°C.
13.5 Disposing of the Inverter
At the end of its service life, dispose of the inverter according to the current locally applicable disposal
regulations for electronic waste. Alternatively, send it back to SMA Solar Technology AG with shipping
paid by sender and labelled "ZUR ENTSORGUNG" ("FOR DISPOSAL") (contact see page 111).
