Zum ersten Mal erlaubt Griechenland Haushalten und Unternehmen die Installation von Balkonsolaranlagen und eigenständigen Batteriesystemen

I think the reason they are not allowed in Hungary is because they can put voltage on the grid even if it’s powered off and under maintenance. Is that even a concern where it’s allowed?

I would imagine these inverters doesn’t give any output if they don’t see a voltage and frequency on the grid. Can they even make the frequency themselves and work off grid?

The Greek Ministry of Environment and Energy has opened a public consultation on the development, installation and grid connection of self-consumption systems, as well as the use of renewable energy for consumers’ own needs. The new framework allows the installation of small solar systems with a capacity of up to 800 watts (balcony photovoltaics) and individual electricity storage systems if they are used exclusively to cover the consumers’ own needs and do not feed electricity into the grid, and meet safety requirements to protect the electricity network and electrical installations.

The reform clarifies and simplifies the procedures for implementing different self-consumption schemes. It also defines the conditions under which storage systems can be added to self-consumption installations. The new rules are intended to make it easier for households, businesses, farmers, local authorities and energy communities to participate in the energy transition.

According to the [announcement](https://ypen.gov.gr/gia-proti-fora-dynatotita-gia-fotovoltaika-sto-balkoni-kai-aftonomes-bataries-se-noikokyria-kai-epicheiriseis/), the government has identified the expansion of self-consumption as an important element of energy democracy. The growing role of self-consumption is reflected in the number of systems already operating in Greece. Since 2020, 37,407 such systems with a total capacity of 1,070 MW have been installed, with households and businesses leading the way. By comparison, between 2015 and 2019, only 1,772 systems with a total capacity of 36 MW were commissioned.

The amendment addresses regulatory issues and introduces greater flexibility for consumers. It clarifies the procedures for implementing and clearing self-consumption schemes and facilitates collective self-consumption, such as in apartment buildings and residential complexes. It allows third parties to develop installations and consumers to be represented by different suppliers. It permits, under certain conditions, switching between different self-consumption schemes and allows one electricity connection to be linked to more than one self-consumption system. It also provides transitional rules for existing installations.

The new framework also introduces digital measures; it accelerates the installation of smart meters and introduces an Electronic Self-Consumption Registry to digitalise procedures and enable faster information exchange.

I wish these were also allowed in Hungary too.
