SMA Solar Technology AG

4 Product Description

BLUETOOTH

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

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.

Fault indicator relay

The inverter is equipped with a fault indicator relay which will signal faults depending on the type
of output device connected. You can connect your own load to this relay (e.g. warning light,
acoustic signal) (see Section6.4 "Connecting the Fault Indicator Relay", page28).

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.

SMA Solar Technology AG

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48).
☐ 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48).
☐ 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.

Cable requirements:

☐ External diameter: 5mm to 13mm
☐ Conductor cross-section: 1.5mm² to 2.5mm²

Operating Manual 23SB13-21TL-BE-en-11

6 Electrical Connection

SMA Solar Technology AG

☐ Insulation stripping length: 4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48). 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 installation 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42).

6 Electrical Connection

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

6.4 Connecting the Fault Indicator Relay

You can use the fault indicator relay to have inverter errors displayed or reported. This requires a
parallel connection. Alternatively, you can choose to have fault-free operation displayed or
reported. This requires a series connection. You can connect several inverters to one fault indicator
or operation indicator. You must connect the fault indicator relay of several inverters in parallel.

In case of critical disturbances, the fault indicator relay will close immediately and trip the warning
signal through the connected load. In case of non-critical disturbances, the fault indicator relay will
only close after several flashing cycles of the yellow LED. When the inverter reconnects to the utility
grid, the fault indicator relay opens again.

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:

• Connect a display device to the fault indicator relay which signals either 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.

7.4.1 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
CEI0-21Int or CEI0-21internal.

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.

Operating Manual 37SB13-21TL-BE-en-11

7 Commissioning

SMA Solar Technology AG

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.

Requirements:

☐ Configured country data set: CEI0-21 Int or CEI0-21 internal or amended country data set

trimmed or Specialsetting based on one of the country data sets mentioned above.

☐ A report for entering the test results according to CEI0-21 must be available.
☐ The inverter must be in operation and in the start-up phase.

Procedure:

1. As soon as the configured country data set appears in the display, tap once on the display
within tenseconds.

☑ A message informing you that the self-test has started is shown in the display:

AvvioAutotest.

✖ The message AvvioAutotest is not shown in the display?

The tenseconds have elapsed so the self-test cannot start.

• Restart the self-test (see Section7.4.2, page39).

2. Tap on the display within 20seconds and enter the subsequent test results into the test report.

☑ The self-test starts.
☑ The inverter displays the results of the individual tests for overvoltage, undervoltage, maximum

frequency and minimum frequency. The results are displayed threetimes in succession for
tenseconds each.
Useful hint: If you want to have the next result displayed without waiting tenseconds, tap twice
on the enclosure lid.

✖ The information Autotestinterroto is shown in the display?

The self-test was cancelled due to an unexpected disconnection condition or the DC voltage is
too low to continue grid feed-in.

• Restart the self-test (see Section7.4.2, page39).

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.

Procedure:

1. Disconnect the circuit breaker and secure it against reconnection.

2. If an external DC load-break switch is installed, disconnect it from all voltage sources.

3. If an ESS is installed, carefully remove the ESS.

4. If the fault indicator relay is used, switch off the load supply voltage, if necessary.

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

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

7. Release and remove all DC connectors. 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.

8. Ensure that no voltage is present at the DC

inputs on the inverter.

9. Pull the AC connection socket out of the AC pin

connector on the inverter. Turn the bush insert of
the AC connection socket to the left until the AC
connection socket releases.

10.

Danger to life due to high voltages

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

• Wait tenminutes before opening the inverter.
