Set the country data set appropriate for your country or purpose within the first ten feed-in hours via the rotary switches in the inverter. After the first ten feed-in hours, the country data set can only be changed by means of a communication product.

A display language is assigned to every country data set. If the display language of the country data set does not match the required language, you can change it after commissioning ( > Changing the Display Language).

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).

1. If you are not sure which standards and directives are valid for your country or purpose, contact the grid operator.

Country data set for operation with external decoupling protection

When operating the PV system with an external decoupling protection, the inverter with a firmware version ≤ 2.99.99.R has the country data set Medium-Voltage Directive (Germany) or MVtgDirective and with a firmware version ≥ 3.00.00.R the country data set DE VDE-AR-N4110:2018 generator ext. Decoup. Protection Device or VDEARN4110/18a. These country data sets allow you to extend the operating range of the inverter for voltage and frequency. These country data sets may only be selected if the PV system is disconnected via external decoupling.

1. If the country data set for operation is set with external decoupling protection, only operate the inverter with an external three-phase decoupling protection. Without external three‑phase decoupling protection, the inverter will not disconnect from the utility grid when the country-specific standard requirement is exceeded.
