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).

SMA Speedwire/Webconnect

The inverter is equipped with SMA Speedwire/Webconnect as standard. SMA Speedwire/
Webconnect is a type of communication based on the Ethernet standard. This enables inverter­optimized 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.

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.

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.

Operating Manual 15SB30-50TL-21-BE-en-11

4 Product Description

SMA Solar Technology AG

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.

Fan retrofit kit

The fan retrofit kit is used for additional inverter cooling at high ambient temperatures and also has
a multifunction relay (for information on installation and configuration, see the installation manual of
the fan retrofit kit). The fan retrofit kit can be retrofitted and must not be operated in parallel with the
SMAPowerControlModule.

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.

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 inverter in areas containing highly flammable materials or gases.

• Do not mount the inverter in a potentially explosive atmosphere.

☐ 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 in the living area, 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47).
☐ To ensure optimum operation, the ambient temperature should be between -25°C and 40°C.
☐ The mounting location should not be exposed to direct solar irradiation. Direct solar irradiation

can cause the inverter to overheat. As a result, the inverter reduces its power output.
☐ Climatic conditions must be met (see Section11 "Technical Data", page47).
☐ 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.

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mm² to 10mm²
☐ 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 circuit breaker.

Make sure to observe the maximum permissible fuse protection (see Section11 "Technical
Data", page47). 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).

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 Section8.5, page40).

Safety in accordance with IEC62109 when the grounding conductor monitoring is
deactivated

In order to guarantee safety in accordance with IEC62109 when the grounding conductor
monitoring is deactivated, carry out 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, page27
). 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 with the same cross­section as the connected grounding conductor to the connecting terminal plate for the AC
cable (see Section6.3.3, page27). 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

Requirements:

☐ 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. If an additional DC load-break switch is available, switch off the DC load-break switch and
secure against reconnection.

3. If the ESS is installed and plugged in, remove the ESS.

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

☑ The display clicks into place.

6. Unscrew the swivel nut from the cable gland.

7. If the outer diameter of the cable is between 15mm and 21mm, remove the inner sealing ring
from the cable gland.

8. Move the swivel nut of the cable gland over the AC cable and then route the AC cable
through the cable gland into the inverter.

9. Dismantle the AC cable.

10. Shorten L and N by 5mm each.

11. Strip the insulation of L, N and the grounding conductor by 18mm.

12. Push the locking levers of the connecting terminal
plate for the AC cable right up to the stop.

13. Connect the grounding conductor, N and L to the connecting terminal plate for the AC cable
in accordance with the labeling.

14.

Danger of crushing fingers 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.

6 Electrical Connection

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.

Cable requirement:

☐ Grounding cable cross-section: max. 10mm²

Procedure:

1. Strip the grounding cable insulation.

2. Release the screw using an Allen key (AF4) until
the grounding cable can be led under the
clamping bracket.

3. Feed the grounding cable under the clamping bracket. Position the grounding conductor on
the left-hand side.

4. Tighten the clamping bracket with the screw and conical spring washer (torque: 6Nm). The
teeth of the conical spring washer must face the clamping bracket.

6.4 DC 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47).

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

(see Section11 "Technical Data", page47).

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).

☐ If the inverter is not equipped with an ESS and the regulations in the country of installation

require an external DC load-break switch, you must install an external DC load-break switch.

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45).

Reduced electromagnetic compatibility of the inverter in case of incorrect DC
connection

If the positive terminal and the negative terminal of a string are not connected to the same
input, electromagnetic compatibility of the inverter cannot be guaranteed. As a result, the
inverter can cause electromagnetic interference in other devices.

• Always connect the positive terminal and the negative terminal of one string to the same
input.

6.4.2 Connecting the PV Array

Destruction of the inverter due to overvoltage

If the open-circuit voltage of the PV modules exceeds the maximum input voltage of the inverter,
the inverter can be destroyed due to overvoltage.

• If the open-circuit voltage of the PV modules exceeds the maximum input voltage of the
inverter, do not connect any strings to the inverter and check the design of the PV system.

Destruction of the measuring device due to overvoltage

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

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. Connect to the communication interface. Installation manual of the
communication interface

2. Check the country data set configuration of the inverter. Supplementary sheet with
the default settings, type la­bel or display

3. 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.

4. 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.

5. Commission the inverter and start a self-test, if required. Section7.4, page34 and

Section7.2, page31

Section7.3, page32

Section7.5, 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38).

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.

device (e.g. computer with BLUETOOTH interface or SMAcommunication product), you can leave
the NetID set to 1.

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.

7.5 Self-Test in Accordance with CEI 0-21 for PV Systems
≤6kW

7.5.1 Starting the Self-Test

The self-test only applies to inverters that are configured with the country data set
CEI 0-21 Int or CEI 0-21 internal.

The self-test is only valid for inverters licensed for Italy and configured with the country data set
CEI 0-21 Int or CEI 0-21 internal.

If the inverter is configured to the country data set CEI 0-21Ext or CEI0-21external, no
self-test is required.

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
CEI0-21. 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 threeminutes.

10 Disconnecting the Inverter from Voltage Sources

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 and secure it against reconnection.

2. If an additional DC load-break switch is available, switch off the DC load-break switch and

secure against re-connection.

3. If an ESS is plugged in, remove the ESS.

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

5. Wait until the LEDs, the display and if necessary, the load connected to the multifunction relay,

are switched off.

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

7. Remove all screws of the lower enclosure lid using an Allen key (AF3) and remove the

enclosure lid.

8. Release and remove all DC connectors. Insert a

slotted screwdriver or an angled screwdriver
(blade width 3.5mm) into one of the slide slots
and pull the DC connectors out downwards. Do
not pull on the cable.

9. Ensure that no voltage is present at the DC inputs of the inverter.

10. Use a suitable measuring device to check that no voltage is present at the AC connecting
terminal plate between L and N and L and PE. Insert the test probe (maximum diameter:
2mm) in each round opening of the terminal.

11. Flip the display up to have more space to make the measurement. Loosen the screw on the
display.

☑ The display clicks into place.

12. Ensure that no voltage is present between any terminal of the multifunction relay and PE of the
AC connecting terminal plate.
