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
3.11.00.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.

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:
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 “Technical Data”, page 95). 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 is compatible with type A and 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.SMASolar.com). Each inverter in
the system must be connected to the utility grid via a separate 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).

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 8.14, page 64).
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 additional
grounding:
· In order to guarantee safety in accordance with IEC 62109 when the grounding
conductor monitoring is deactivated, you have to connect additional grounding
(see Section 6.2.3, page 34): The additional grounding conductor must have the
same crosssection as the connected grounding conductor at the connecting
terminal plate for the AC cable. 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 that
has at least the same cross-section as the connected grounding conductor to
the connecting terminal plate for the AC cable (see Section 6.2.3, page 34).
This prevents touch current if the grounding conductor at the connecting
terminal plate for the AC cable fails.
6.2.2 Connecting the Inverter to the Utility Grid
Requirements: Only the terminal block supplied may be used for the AC
connection. 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 circuit breaker and secure it against
reconnection.

3. Thread the swivel nut over the AC cable.
4. Thread the AC cable through the cable gland of the AC connection:
· If the external diameter of the cable is 5 mm to 7 mm, thread the AC cable
through the cable gland directly.
· If the external diameter of the AC cable is
8 mm to 13 mm, first remove the inner sealing
ring from the cable gland and then thread the
AC cable through the cable gland. When
doing so, ensure that the outer sealing ring is positioned correctly in the cable gland.

LN
12. Ensure that the terminal block is securely in place by slightly pulling
it.
6.2.3 Connecting Additional Grounding
If additional grounding or equipotential bonding is required locally, you can
connect additional grounding to the product. This prevents touch current if
the grounding conductor at the terminal for the AC cable fails. The required
clamping bracket, the cylindrical screw M5x16, the washer and the spring lock
washer are part of the scope of delivery of the inverter.
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
Procedure: 1. Strip off 12 mm of the grounding cable insulation. 2. Insert the
screw through the spring lock washer, the clamping bracket and the washer.

7 Commissioning
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 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 44).
· 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 3.11.00.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
See
1. Commission the inverter.
Section 7.2, page 44
2. Establish a connection to the user interface of the inverter. Section 8.1, page 48 There are various connection options to choose from for this: · Direct connection via WLAN · Direct connection via Ethernet · Connection via WLAN in the local network · Connection via Ethernet in the local network
3. Log into the user interface.

Requirements: The AC circuit breaker must be correctly rated and mounted. The
product must be correctly mounted. All cables must be correctly connected.
Procedure: 1. Switch on the AC circuit breaker. 2. Turn the DC load-break
switch of the inverter to position I.
All 3 LEDs light up. The start-up phase begins.
All 3 LEDs go out again after approximately 90 seconds.
3. If the green and red LEDs flash simultaneously during initial
commissioning, operation is stopped because no country data set has been set
yet. For the inverter to begin operation, the configuration must be completed
and a country data set must be set.
4. If the green LED is still flashing, the conditions for activating feed-in
operation are not yet met. As soon as the conditions for feed-in operation are
met, the inverter starts with feed-in operation and, depending on the
available power, the green LED will light up continuously or it will pulse.
5. If the red LED lights up, an event has occurred. Find out which event has
occurred and, if necessary, initiate countermeasures.

assistant (recommended) · Manual configuration
Accepting the settings Saving the made settings is indicated by an hourglass
symbol on the user interface. If the DC voltage is sufficient, the data is
transferred directly to the inverter and accepted. If the DC voltage is too
low (e. g. in the evening), the settings are saved, but they cannot be
directly transferred to or accepted by the inverter. As long as the inverter
has not yet received and accepted the settings, the hourglass symbol will
continue to be displayed on the user interface. The settings will be accepted
when there is sufficient DC voltage applied and the inverter restarts. As soon
as the hourglass symbol appears on the user interface, the settings have been
saved. The settings will not be lost. You can log off of the user interface
and leave the system.
Adopting the Configuration from a File You can adopt the inverter
configuration from a file. To do this, there must be an inverter configuration
saved to a file.
Procedure: 1. Select the configuration option Adopting configuration from a
file. 2. Select [Browse…] and select the desired file. 3. Select [Import
file].
Configuring the Installation Assistant (Recommended)

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.
Procedure: 1. Select the menu Device Configuration. 2. Select [Settings]. 3.
Select [Starting the Self-Test] in the subsequent context menu. 4. Follow the
instructions appearing in the dialog and save the report of the self-test
where necessary.

8.10 Configuring the Country Data Set
For the product to begin operation, 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). As long as no country data set is set,
operation of the product will remain stopped. This state is signaled by the
green and red LEDs flashing simultaneously. Once configuration of the product
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).
