SMA Solar Technology AG The Communication Module (Quick Module)
5.3.1 SMA Grid Guard Protected Country Data Sets
In some countries, the local grid connection requirements demand a mechanism which prevents the
parameters for the grid feed‑in from being changed. Some country data sets are therefore protected
and can only be unlocked with a personal access code, the SMA Grid Guard code.
SMA Grid Guard protected country data sets are automatically blocked for 10 feed‑in hours after
commissioning, or after the last alteration. If the country data set is changed via the rotary switch after
these 10 feed‑in hours, the inverter will not accept the changes and displays the error message
"Grid parameter locked". If, however, a later change to the country data set only relates to a change
of the display language, this change is immediately applied.
It is a lso pos sib le t o se t co untr y da ta s ets (pa ram ete r "C ntr ySet" or "Set country standard"), and to lock
or unlock these manually via a communication product. To lock a data set, enter the digit sequence
"54321" instead of the password into the SMA Grid Guard Code field. The data set can only be
unlocked by entering a personal, 10‑digit SMA Grid Guard code which is valid for a maximum of
10 feed‑in hours. The application form for the personal access code is located in the download area
at www.SMA.de/en, in the "Certificate" category for each inverter. The language can be configured
without a password, regardless of the country data set.
Changing parameters in SMA Grid Guard protected country data sets
If the parameters within protected country data sets are changed, these are no longer
protected and instead of the standard, "ADJ" or "Special setting" is displayed. In this case
the parameters are not changed automatically after 10 feed‑in hours, but have to be
manually locked. To manually lock the parameters, set the SMA Grid Guard code to
"54321".
Detailed information on parameter settings
You will find information on making adjustments and changing parameters in the
corresponding user manual for your software.
The last change (executed via rotary switch or communication product) is always verified and
activated if applicable. This means that you cannot always read off t he actual c ountry setting from the
switch position.

5.3.2 Checking the Country Standard
The switch position 0 / 0 indicates the delivered state. If you have ordered the inverter with specific
count ry setting s, the y will have alr eady been pres et at the factory via a c ommunicat ion pr oduct. In t his
case, you will not be able to recognize the setting by the switch position. If changes are made via the
rotary switches or via a communication product, the default grid parameters are overwritten. They
cannot be restored, and must be re‑entered via a communication product. The display language can
be changed at any time using the rotary switches, independently of the grid parameters. This means
that the default grid parameters remain unchanged, but the display messages are shown in the set
language. For devices ordered without any specified country of installation, the standard setting is
"VDE0126‑1‑1" and the language "Deutsch" (German).
Changes will be accepted immediately after switching the miniature circuit‑breaker on. If an
unprogrammed switch setting is selected, the inverter issues an error message on the display and the
last valid setting is retained.
Check whether the inverter is set to the installation country.
Before commissioning:
• Check that the country setting of the inverter is correct by comparing the additional sheet
provided with the default settings of the inverter.
After commissioning:
• Check that the country standard is correct on the basis of the display message during
(re‑)commissioning (see section 7.2"Display Messages During the Startup Phase" (page51)).
or
• Check that the country standard is correct using the "SMA grid guard" measuring channel via
a communication product.
Display language
Once you have set the country standard, you can always set the display language later
using rotary switch B. However, you h ave to then set rotary switch A to "0" in order to keep
the country data set.
The operating parameters define which parameter set refers to which setting. The parameters can be
read out using a communication product. A detailed description of the parameters and measured
values for the inverter is available in the download area at www.SMA.de/en in the
"Technical Description" category for the respective inverter.

SMA Solar Technology AG The Communication Module (Quick Module)
If the inverter is not set to the installation country, there are several ways of configuring the required
country standard.
• Setting via 2 rotary switches in Quick Module, as described in section 5.3.4"Setting the
Country Standard and Language using the Rotary Switch" (page28).
• Alternatively you can adjust the setting via the "CntrySet" or "Set country standard" parameters
with a communication product (e.g. Sunny Data Control or Sunny Explorer), once you have
commissioned the inverter.
•If you require adjusted parameter settings for your installation site, you can change these with
the help of a communication product.
5.3.3 Opening the Quick Module

5.3.4 Setting the Country Standard and Language using the Rotary Switch
1. Open the Quick Module, as described in section 5.3.3"Opening the Quick Module"
(page27).
2. Set the arrows on both left rotary switches
(A and B) to the desired positions using a
screwdriver (see table in section 5.3.2"Checking
the Country Standard" (page24)). For this
purpose, use a screwdriver with a blade width of
2.5 mm.
Jumper for English
You can also set the language to English by
means of a jumper (e.g. for service purposes).
• To do this, place the jumper onto both
left pins as shown in the diagram on the
right.
☑ The country standard and the language are set.
5.3.5 Communication via Bluetooth
Communication via Bluetooth with a communication product is activated as standard. Networking via
Bluetooth with other inverters is deactivated ex works.
The following configuration settings are possible via a rotary switch (switch C):
Switch position (NetID) Setting
0off
1 Communication via Bluetooth with communication product possible,
no networking with other inverters (default settings)
2 ... F Networking with other inverters and/or communication products
In order to restrict communication via Bluetooth between the inverters of your plant and those of
neighboring plants, you can assign an individual NetID to the inverters of your plant (switch position
2 ... F). However, this is only necessary if neighboring plants are within a radius of 500 m.
So that all inverters in your PV plant are detected by your communication product, all inverters must
have the same NetID.
