We will look at the lists published by E.ON and MVM of the equipment they accept, and how you can check whether a particular model is included. We will also explain who is responsible for approval and how you can find information in the official databases.

Finally, we will answer where you can purchase system-approved inverters and what types SOLARKIT recommends from its range. This article will help you choose a reliable and compliant solar power system with confidence in accordance with the 2025 regulations.

Why is it important to choose based on the list of applicable inverters?

The inverter is not only the heart of the solar system, but also a key component for connecting to the grid — which is why it is essential to choose a type that is included in the current list of approved inverters. Without this, your service provider may not allow you to connect to the grid or may change the connection conditions at a later date. These documented, approved inverters comply with technical and safety regulations and the professional guidelines of the Hungarian Chamber of Engineers, and also include a network code that complies with Hungarian regulations, such as the VDE-AR-N 4105 standard.

Nowadays, with the regulatory environment constantly changing, it is particularly important to use only devices that have valid certificates and are included in the lists of E.ON, MVM or other service providers. This provides confidence in operation and protects against future costs arising from incompatibility.

Overall, the use of an approved inverter list is therefore of strategic importance not only from a technical point of view, but also from a legal and financial perspective. Safety, reliability and compliant operation – these are the principles that should guide your choice.

Who is responsible for approving inverters in Hungary?

In Hungary, electricity suppliers are primarily responsible for approving inverters: E-ON (which includes ELMŰ and ÉMÁSZ) and MVM Démász manage the lists. As the list is shared, if one supplier adds an inverter to the list, it will appear on all lists when they are next updated. They examine the manufacturers' documentation and only inverters that comply with technical, safety and network requirements are added to their lists.

Inverters must comply with standards such as VDE-AR-N 4105 or similar international standards, and the relevant certificates must be updated from time to time (the validity date can be found on the lists).

How can you check whether an inverter is on the approved list?

1. Visit your electricity supplier's document archive, for example on the E‑ON/ELMŰ, ÉMÁSZ or MVM Démász website, where you can download the latest PDFs from the "Approved inverters" list.
2. Find the exact name of the manufacturer and type. The lists contain the type number, phase number, power limits, and certificate validity. For example, E‑ON's list contains the version valid from July 3, 2025.
3. Please note any restrictions on use (e.g. only three-phase systems or time-limited approvals) – these are listed in detail at the end of the lists.
