This standard operating procedure (SOP) details the steps that are required to change the default grid
code setting of a Zeversolar three phase inverter.
1.2 Assumed Knowledge
This guide assumes the following:
A Zeversolar three phase inverter has been installed;
The installation manual has been read and fully understood.
1.3 IMPORTANT – CHECK GRID CODE SETTING DURING COMMISSIONING!
The grid code setting should be checked during the commissioning of a PV plant. It is essential to
ensure that the correct grid code/safety setting has been selected for the relevant region. Each
Zeversolar inverter is set to a default grid code which is based on the serial number suffix that can
be found on the label affixed to the inverter and its packaging, see Fehler! Verweisquelle konnte nicht
gefunden werden. below.
Figure 1 - Serial Number with UK Suffix
Inverters shipped to Europe have three distinct suffixes and as such the default grid code is set
accordingly, please see Table 1.
Table 1 - Default Grid Code Settings
Therefore it is necessary to check the serial number suffix and ensure that the correct grid code is
set. For example, an inverter being installed in the UK may have the DE suffix, in this case the inverter
grid code should be changed from the “VDE-AR-N-4105” grid code to the relevant UK grid code “G83/2
or G59/3.”

1.4 When is Changing the Grid Code Required
As mentioned above it is necessary to change the grid code if the inverter is not installed in the region
to which the default grid code is set to. The grid code should also be changed if the inverter is installed
in the following countries:-
Austria, Belgium, France, Greece, Northern Ireland, Poland, Republic of Ireland, Switzerland,
Turkey.
Please note: please refer to the Certificate Overview available from the Zeversolar website to
determine for which regions the Zeversolar inverters are certified.

1.6 Basic & Advanced Settings
This guide is intended for inverters that have both the “Basic” and “Advanced” settings which can be
selected from the front panel display. If the inverter does not have both menu items then the “Safety
Setting” can be accessed by simply selecting “Settings” on the “Menu” screen.

6. On the “Safety” menu the grid code
shown as “Standard” will be the first
item highlighted.
7. To change the “Standard” use the arrow
