SMA Solar Technology AG

Operating Manual 9STP5-12TL-20-BE-en-15

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 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.

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
that there is continuous conduction. Observe the applicable local regulations.

Risk of burns due to hot enclosure parts

Some parts of the enclosure can get hot during operation.

• During operation, do not touch any parts other than the enclosure lid of the inverter.

Damage to the seal of the enclosure lid in sub-zero conditions

If you open the enclosure lid in sub-zero conditions, the sealing of the enclosure lid can be
damaged. This can lead to moisture entering the inverter.

• Do not open the inverter at ambient temperatures lower than -5°C.

inverters of a small-scale system and the Internet portal SunnyPortal without any additional

4 Product Description

SMA Solar Technology AG

Operating Manual 17STP5-12TL-20-BE-en-15

communication device and for a maximum of 4 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.

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.

Modbus

The inverter is equipped with a Modbus interface. The Modbus interface is deactivated by default
and must be configured as needed.

The Modbus interface of the supported SMA devices is designed for industrial use and has the
following tasks:

• Remote query of measured values

• Remote setting of operating parameters

• Setpoint specifications for system control

RS485 interface or SMA Power Control Module

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 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 RS485 interface and the SMAPowerControlModule can be retrofitted and may not be
operated in parallel.

If you want to operate the RS485 interface or the SMAPowerControlModule in parallel with the
multifunction relay in the inverter, you must ensure that a voltage of no more than 30VDC or
25VAC is connected to the multifunction relay.

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.

4Product Description

SMA Solar Technology AG

Operating ManualSTP5-12TL-20-BE-en-1518

Multifunction Relay

The inverter is equipped with a multifunction relay as standard. The multifunction relay is an
interface that can be configured for the operating mode used by a particular system.

Error message required by standard

In some countries, signaling of errors is required by standards, e.g. IEC62109-2. In order to
meet the standard requirement, take one of the following measures:

• Operate the multifunction relay in the operating mode Fault indication or FltInd and
connect a display unit to the multifunction relay that signals an error or the undisturbed
operation of the inverter.

• Activate the error alarm in SunnyPortal (for information on receiving error alarms via
SunnyPortal, see the SunnyPortal user manual at www.SunnyPortal.com). This requires
the inverter to be registered in SunnyPortal.

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 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.

5 Mounting

5.1 Requirements for Mounting

Requirements for the mounting location:

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.

☐ Do not mount the inverter on a pillar.
☐ 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

Section11 "Technical Data", page59).

☐ The mounting location must not be exposed to direct solar irradiation. Direct solar irradiation

can result in the premature aging of the exterior plastic parts of the inverter and direct solar
irradiation can cause the inverter to overheat. 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 40°C.
☐ Climatic conditions must be met (see Section11 "Technical Data", page59).

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 way that display messages and LED signals can be

read without difficulty.

Risk of injury when lifting the inverter, or if it is dropped

The inverter weighs 38kg. 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.

• Carry and lift the inverter upright with the help
of several people. Use both hands to grasp the
recessed grips at the top and bottom, or use a
steel rod (diameter: 30mm at maximum). This
will prevent the inverter from tipping forward.

Damage to the ESS pin connector from dirt and foreign bodies

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). This will impair the
function of the ESS.

• Always set the inverter down on a level support surface or lay it on its back.

Procedure:

1.

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. Use at least one hole on the right-hand and left-hand side in the wall mounting
bracket.

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.

6.1 Safety during Electrical Connection

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 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.

Damage to seals on the enclosure lids in subfreezing conditions

If you open the enclosure lid when temperatures are below freezing, the enclosure lid seal could
be damaged. This can lead to moisture entering the inverter.

• Only open the enclosure lid if the ambient temperature is not below -5°C

• If a layer of ice has formed on the seal of the lid when temperatures are below freezing,
remove it prior to opening the enclosure lid (e.g. by melting the ice with warm air). Observe
the applicable safety regulations.

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.

6.3 AC Connection

6.3.1 Requirements for the AC Connection

Cable requirements:

• External diameter: 12mm to 21mm

• Conductor cross-section: 1.5 to 6 mm²

• Insulation stripping length: 18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59). 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).

☐ If a residual-current device with a tripping threshold of 30mA is required and used, you must

set the tripping threshold of the residual-current device in the inverter to 30mA (see
Section8.7, page51).

Operating Manual 29STP5-12TL-20-BE-en-15

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).

6.3.2 Connecting the Inverter to the Utility Grid

specified in the operating parameters.

Procedure:

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

2. Unscrew all six screws of the enclosure lid using an Allen key (AF5) and remove the enclosure
lid. Ensure that the conical spring washers are retained.

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

4. Attach the M32x1.5 cable gland to the enclosure opening for the AC cable using a 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. Dismantle the AC cable.

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

8. Strip 18mm of the insulation from each of L1, L2, L3, N and the grounding conductor.

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

• Do not place your fingers under the locking levers.

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 terminal 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: 16mm² at maximum

Procedure:

1. Strip the grounding cable insulation.

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

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 enables you to communicate
using 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

1. Call up the user interface of the communication product or software and log in as Installer or
User.

2. If required, enter the SMAGridGuardcode.

3. Select and set the required parameter.

4. Save settings.

8.6 Configuring the ModbusFunction

The Modbus interface is deactivated by default and the communication ports 502 set. In order to
access SMA invertes with SMA Modbus® or SunSpec® Modbus®, the Modbus interface must be
activated. After activating the interface, the communication ports of both IP protocols can be
changed.

For information on commissioning and configuration of the Modbus interface, see the Technical
Information "SMAModbus® Interface" or in the Technical Information "SunSpec® Modbus®
Interface" at www.SMA-Solar.com.

Data security during activated Modbus interface

If you activate the Modbus interface, there is a risk that unauthorized users may access and
manipulate the data or devices in your PV system.

• Take appropriate protective measures such as:
– Set up a firewall.
– Close unnecessary network ports.
– Only enable remote access via VPN tunnel.
– Do not set up port forwarding at the communication port in use.
– In order to deactivate the Modbus interface, reset the inverter to default settings or

deactivate the activated parameter again.

Procedure:

• Activate the Modbus interface and adjust the communication ports if necessary (see the
Technical Information "SMAModbus® Interface" or "SunSpec® Modbus® Interface" at
www.SMA-Solar.com).

8.7 Setting the Tripping Threshold of the Residual-Current
Device

If a residual-current device with a tripping threshold of 30mA is specified and installed, you must
set the parameter RCD adjustment to 30mA (for further information, see the Technical
Information ""Leading Leakage Currents"" at www.SMA-Solar.com).

The basic procedure for changing operating parameters is explained in another section (see
Section8.5 "Changing Operating Parameters", page49).

• Select the parameter RCDadjustment and set it to 30mA.

8.8 Changing the Operating Mode of the Multifunction
Relay

The default operating mode of the multifunction relay is Fault indication (FltInd) . If you decide to
use another operating mode and have established the correct electrical connection for this
operating mode and the associated connection variant, you will have to change the operating
mode of the multifunction relay and make other settings, if necessary.

The basic procedure for changing operating parameters is explained in another section (see
Section8.5 "Changing Operating Parameters", page49).

Procedure:

1. Select the parameter Operating mode of multifunction relay or Mlt.OpMode and set the
desired operating mode.

2. Once you have set the operating mode Self-consumption or SelfCsmp, you can configure
other settings:

• Select the parameter Minimum On power for MFR self-consumption or
Mlt.MinOnPwr and set the desired value. This will configure the power threshold from
which a load is to be activated.

• Select the parameter Minimum power On time, MFR self-consumption or
Mlt.MinOnPwrTmm and set the desired value. This will configure the minimum time for
which the power must have exceeded the minimum switch-on power threshold in order to
trip activation of the load.

• Select the parameter Minimum On time for MFR self-consumption or
Mlt.MinOnTmm and set the desired value. This will configure the minimum time for
which the load remains activated.

3. If you have set the operating mode Control via communication or ComCtl, select the
parameter Status of MFR with control via communication or Mlt.ComCtl.Sw and set the
desired value. This will configure the status at which the multifunction relay is controlled via a
communication product.

4. If you have set the operating mode Battery bank or BatCha, make further settings:

8 Configuration

SMA Solar Technology AG

Operating Manual 51STP5-12TL-20-BE-en-15

• Select the parameter Minimum On power for MFR battery bank or
Mlt.BatCha.Pwr and set the desired value. This will configure the power threshold from

which the battery is to be charged.

• Select the parameter Minimum time before reconnection of MFR battery bank or
Mlt.BatCha.Tmm and set the desired value. This will configure the minimum time which
must elapse after charging the battery before the battery can be charged again.

8.9 Setting SMA OptiTrac Global Peak

For partially shaded PV modules, you should set the interval at which the inverter is to optimize the
MPP of the PV system. If you do not want to use SMAOptiTracGlobalPeak feature, you can
deactivate the feature.

The basic procedure for changing operating parameters is explained in another section (see
Section8.5 "Changing Operating Parameters", page49).

Procedure:

• Select the parameter Cycle time of the OptiTrac Global Peak algorithm or
MPPShdw.CycTms and set the required time interval. The ideal time interval is usually six

minutes. This value should only be increased if the shading situation changes extremely slowly.

☑ The inverter optimizes the MPP of the PV system at the predetermined time interval.

• In order to deactivate the SMAOptiTracGlobalPeak feature, select the parameter OptiTrac
Global Peak switched on or set MPPShdw.IsOn to Off.
