NOTICE
Damage to the product due to cleaning agents The use of cleaning agents may
cause damage to the product and its components.
· Clean the product and all its components only with a cloth moistened with
clear water.
Change to the names and units of grid parameters to comply with the
gridconnection requirements in accordance with Regulation (EU) 2016/631 (valid
from April 27, 2019) To comply with the EU grid-connection requirements (valid
from April 27, 2019) the names and units of grid parameters were changed. This
change is valid from firmware version 3.00.00.R if a country data set for
fulfilling the EU grid-connection requirements (valid from 2019-04-27) is set.
Names and units of grid parameters for inverters with firmware version
2.99.99.R are not affected by this change and remain valid. This also applies
from firmware version 3.00.00.R if a country data set that is valid for
countries outside the EU is set.
A country data set must be set for feed-in operation From firmware version
4.00.00.R, the activation conditions for feed-in operation were changed. To
ensure the inverter begins feed-in operation during initial commissioning, a
country data set must be set (for instance via the installation assistant on
the user interface of the product, or via a communication product). If no
country data set is set, then feed-in operation will be stopped. This state is
signaled by the green and red LEDs flashing simultaneously. The inverter will
automatically start feed-in operation only after the inverter configuration is
completed.
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 standards and directives are valid for your
country or purpose, contact the grid operator.

4 Product Overview
SMA ShadeFix
The inverter is equipped with the shade management system SMA ShadeFix. SMA
ShadeFix uses an intelligent MPP tracking system to determine the operating
point with the highest output during shading conditions. With SMA ShadeFix,
inverters use the best possible energy supply from the PV modules at all times
to increase yields in shaded systems. SMA ShadeFix is enabled by default. The
time interval of SMA ShadeFix is usually 6 minutes. This means that the
inverter determines the optimum operating point every 6 minutes. Depending on
the PV system or shading situation, it may be useful to adjust the time
interval.
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 ArcFix
SMA ArcFix is a system for DC arc fault detection and interruption in
accordance with EN 63027. A detected electric arc causes a brief interruption
of the feed-in operation. An event message is entered on the user interface
when an electric arc is detected. If SMA Smart Connected is activated, the
user and installer are additionally informed of the detected electric arc by
e-mail. After a waiting period, the inverter starts automatically and checks
whether the electric arc is still present. If the electric arc is still
present, the inverter disconnects from the grid again and the process is
repeated. SMA ArcFix is switched off by default and must be activated on the
user interface.
SMA Smart Connected
SMA Smart Connected is the free monitoring of the product via the SMA Sunny
Portal. Thanks to SMA Smart Connected, the operator and qualified person will
be informed automatically and proactively about product events that occur.

stripping length: 12 mm Sheath stripping length: 50 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).

6 Electrical Connection
Grounding cable requirements:
Use of fine-stranded conductors You can use an inflexible or a flexible, fine-
stranded conductor.
· When using a fine-stranded conductor, it has to be double crimped by a ring
terminal lug. Make sure that no insulated conductor is visible when pulling or
bending. This will ensure sufficient strain relief by means of the ring
terminal lug.
Grounding cable cross-section: max. 10 mm²
Load-break switch and cable protection:
NOTICE
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 13, page 107). This will prevent residual voltage from 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: The inverter does not require an external
residual-current device when operating. If local regulations require the use
of a residual-current device, the following must be observed:
The inverter with firmware version 3.00.10.R is compatible with type A/B
residual-current devices that have a rated residual current of 30 mA or higher
(information about the selection of a residual-current device see technical
information “Criteria for Selecting a Residual-Current Device” at www.SMA-
Solar.com). Each inverter in the system must be connected to the utility grid
via a separate residual-current device.
When using residual-current devices with a rated residual current of 30 mA,
the rated residual current must be set in the inverter (see Section 8.20, page
71). In this way the inverter reduces the operational leakage currents and
prevents a false triggering of the residual-current device.
Overvoltage category: The product can be used in grids of overvoltage category
III or lower in accordance with IEC 60664-1. That means that the product 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 Electrical Connection
SMA Solar Technology AG
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 disable the
grounding conductor monitoring. This can be necessary, for example, in a Delta
IT system or other grid configurations 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 disabled after initial start-up
depending on the grid configuration (see Section 8.17, page 70).
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, you have to connect an
additional grounding conductor to the inverter.
· Connect an additional grounding conductor that has an cross-section of at
least 10 mm (see Section 6.2.3, page 34). This prevents touch current in the
event of the grounding conductor on the AC connector bush insert failing.
Connection of an additional grounding conductor In some countries, an
additional grounding conductor is generally required. In each case, observe
the locally applicable regulations.
· If an additional grounding conductor is required, connect the one that has
an crosssection of at least 10 mm (see Section 6.2.3, page 34). This prevents
touch current in the event of the grounding conductor on the AC connector bush
insert failing.
6.2.2 Connecting the Inverter to the Utility Grid
Requirements: The connection requirements of the grid operator must be met.
The grid voltage must be within the permissible range. The exact operating
range of the inverter is specified in the operating parameters.
Procedure: 1. Disconnect the AC miniature circuit breaker and secure against
reconnection.

4. Dismantle the AC cable by 50 mm. 5. Shorten L and N by 8 mm each, so that
the grounding conductor is 8 mm longer. This ensures
that the grounding conductor is the last to be pulled from the screw terminal
in the event of tensile strain. 6. Strip the insulation of L, N and the
grounding conductor12 mm. 7. In the case of fine stranded wire L, N and PE are
to be fitted with bootlace ferrules. 8. Assemble the AC connector and connect
the conductor to the AC connector (see manual of the AC connector). 9. Ensure
that all conductors are securely connected to the AC connector. 10. Plug the
AC connector into the jack for the AC connection. When doing so, align the AC
connector so that the key on the inverter AC jack is inserted into the keyway
on the AC connector bush insert.

7 Commissioning 7.1 Commissioning Procedure
This section describes the commissioning procedure and gives an overview of
the steps you must perform in the prescribed order.
Commissioning a product in SMA Energy Systems If the product is used in an SMA
Energy System, the commissioning must be performed according to the manual of
the SMA Energy System. The procedure and the sequence may differ from the
steps described in this section.
· Commissioning an SMA Energy System (see system manual of the SMA Energy
System).
Commissioning an inverter that is captured in a communication device
When the inverter is captured in a communication device, the communication
device (e.g. SMA Data Manager) is the unit for configuring the total system.
The configuration is transferred to all inverters in the system. The system
password assigned via the communication device is also the password for the
user interface of the inverter.
· Commission the inverter (see Section 7.2, page 47).
· The initial configuration of the inverter is made via the communication
device. The configuration is transferred to the inverter and the settings of
the inverter are overwritten.
· Deactivate the Webconnect function of the inverter via the Sunny Portal.
This prevents unnecessary connection attempts of the inverter with Sunny
Portal.
A country data set must be set for feed-in operation
From firmware version 4.00.00.R, the activation conditions for feed-in
operation were changed.
To ensure the inverter begins feed-in operation during initial commissioning,
a country data set must be set (for instance via the installation assistant on
the user interface of the product, or via a communication product).
If no country data set is set, then feed-in operation will be stopped. This
state is signaled by the green and red LEDs flashing simultaneously.
The inverter will automatically start feed-in operation only after the
inverter configuration is completed.
Procedure 1. Commission the inverter.

7.4 Starting the Self-Test (for Italy and Dubai)
The self-test is only required for inverters that are to be commissioned in
Italy or Dubai. The Italian standard CEI 0-21 and the DEWA (Dubai Electricity
and Water Authority) stipulate that all inverters that feed into the utility
grid are equipped with a self-test function. 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.
Requirements: The country data set of the inverter must be set to CEI 0-21
internal or DEWA 2016 internal.

is completed, the product will start operating automatically.
By default, the inverter is set to a universally valid country data set. You
must adjust the country data set for the installation site.
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 standards and directives are valid for your
country or purpose, contact the grid operator.
Change to the names and units of grid parameters to comply with the
gridconnection requirements in accordance with Regulation (EU) 2016/631 (valid
from April 27, 2019)
To comply with the EU grid-connection requirements (valid from April 27, 2019)
the names and units of grid parameters were changed. This change is valid from
firmware version 3.00.00.R if a country data set for fulfilling the EU grid-
connection requirements (valid from 2019-04-27) is set. Names and units of

8.19 Generating the I-V Characteristic Curve
8 Operation
During the measurement, the inverter can briefly interrupt the feed-in or feed
in with reduced power. The duration of a measurement is approx. 20 seconds per
MPP tracker. To avoid misuse of the function and thus yield loss, the
measurement can be carried out a maximum of 10 times per day. If more than 10
measurements per day are to be carried out, the inverter must be restarted.
The measuring curve has over 200 measuring points. The display is from 0 V up
to the maximum MPP voltage of the inverter. The current is limited by the
maximum possible input current of the inverter. The data is stored on the user
interface until the next measurement. Further information as well as help for
the interpretation of the I-V-characteristic curve can be found in the
technical information “I-V diagnostic function: Determination of the generator
characteristic curve by the inverter for fault detection in the PV array”.
Using the function when using external module optimizers is not recommended.
Using the function when using external module optimizers does not produce
interpretable results and is therefore not recommended.
Requirements: · In order to avoid misinterpretation of the determined
characteristic curve at low powers, a measurement should be carried out at at
least 50% of the inverter’s nominal power. · In the case of comparative
measurements (e.g. at annual intervals), similar ambient conditions (solar
irradiation, shading, temperature) should prevail.
Procedure: 1. Log on to the user interface of the inverter. 2. Click on
Diagnosis in the menu. 3. Click on [Start new measurement]. 4. Go to [PDF
export] or [CSV export] to export the data shown.
8.20 Setting the Rated Residual Current of the ResidualCurrent Device
When using residual-current devices with a rated residual current of 30 mA,
set the rated residual current to 30 mA. In this way the inverter reduces the
operational leakage currents and prevents a false triggering of the residual-
current device (further information see technical information “Leading Leakage
Currents” at www.SMA-Solar.com).

8.24 Firmware Update
You can activate an automatic firmware update in the inverter or in the
communication product. If no automatic update is set in the communication
product (e.g. SMA Data Manager or Sunny Home Manager) or in Sunny Portal, you
have the option of carrying out a manual firmware update. You have the
following options to update the firmware:
· Automatic Firmware Update (Recommended) · Update the firmware with the
existing update file via the user interface of the inverter. · Search and
install the firmware via the user interface of the inverter.
8.24.1 Activating Automatic Firmware Update
You can activate the automatic firmware update in the inverter or in the
communication product. If the automatic firmware update is activated in the
inverter, the inverter searches for updates and carries out the update. If the
automatic firmware update is activated in the communication product, the
communication product searches for updates for the inverter and carries out
the update of the inverter. In this case, the automatic firmware update is
deactivated by default in the inverter. This prevents multiple downloads of
updates. In this section we describe how to activate the automatic firmware
update in the inverter. The procedure for activating the automatic firmware
update for detected devices in the communication product can be found in the
manual for the communication product. The basic procedure for changing
operating parameters is explained in another section (see Section 8.12, page
66).
Procedure:
· In the parameter group Device > Update, select the Automatic Update
parameter and set to Yes.
