Support for a solar plant with battery and inverter: what we know about 2027

Summary: what is known at the end of October 2026

Officially (enmin.lrv.lt, checked 25 Oct 2026): new support calls for residents are planned for 2027; funding goes to solar plants combined with batteries that keep the home supplied during outages; the funding conditions will be approved only after the European Commission’s consent. Energy Minister L. Savickas said on 15 Oct 2026 that an EC decision is expected by the end of the year.

Citing ministry information, the media expect the calls in Q1 2027, but the ministry itself names no quarter, and planned funds are not yet a guaranteed grant. We check the status in official sources and update it in our support hub.

Why 2027 funds the whole package: plant, inverter and battery

On 15 Oct 2026 Energy Minister L. Savickas said that of roughly 200,000 prosumers only 15,000–16,000 can run in island mode, i.e. power the home when the grid goes down. Support should therefore encourage the whole package – not just panels on the roof, but a suitable inverter and battery too. The long-term ambition, according to the minister, is over €100M of support and about 30,000 new prosumers.

On 16 Sep 2026 the Government approved the so-called Storm package: prosumers living in remote and hard-to-reach areas are to receive priority support of up to 100% for solar plants, batteries and off-grid solutions, reaching about 30,000 consumers. Funding sources and call rules for this direction have not been published, and it has not been officially linked to the 2027 package support.

Why an inverter with a backup function matters

An ordinary grid-tied inverter must shut down during an outage, so a solar plant without storage cannot power the home even on a sunny day, and a battery alone does not guarantee power either. For the home to keep running off-grid you need a hybrid inverter with a backup (EPS) function, a compatible battery and a separate backup circuit in the distribution board. Citing ministry information, the media report that such systems are what 2027 support will target.

The pilot call did not formally require a hybrid inverter – a CE-marked inverter suitable for solar plants with at least a 5-year warranty was enough. The new call’s technical requirements are not yet published. If you are choosing equipment now, pick a hybrid inverter with a backup function that is on the battery maker’s compatibility list – for example the Solis S6-EH3P, Deye SUN SG05LP3, SolaX X3-Hybrid G4 or Solplanet ASW kH-T3 from our inverter catalogue – and a battery from our storage catalogue.

The previous ‘solar plant + battery’ call: terms and results

The pilot call was initiated by the Ministry of Energy, administered by APVA and funded by the state. Applications opened on 23 Oct 2025; the grant was a fixed €5,012.19 with an LFP battery or €4,572.30 with a lithium-ion battery. Applicants had to install a solar plant of at least 5 kW (up to 100 kW) and a battery of at least 10 kWh (up to 100 kWh) on the same electricity consumption site, with permitted grid export of no more than 1 kW, kept for 2 years. A plant alone or a battery alone was not funded.

The call was for households that had already installed the system: the application and payment claim were submitted via APVIS only after full installation, equipment had to be bought and installed no earlier than 1 Sep 2025, and ESO’s updated ownership-boundary act had to be obtained before applying. Claims worth €3.2M arrived in the first month; on 30 Jan 2026 the ministry added €10.13M (the call grew to €15.43M) and on 4 Jun 2026 another €6.9M for reserve-list applicants. The reserve list closed on 5 June 2026; more than a thousand residents became prosumers under the measure.

How to prepare in advance

Previous household calls were for people who had already installed their systems, and funds ran out within one or a few days: the pilot call accepted equipment installed from 1 Sep 2025 although it opened on 23 Oct 2025, and the 2025 storage calls accepted installations from 7 Jan 2025. That is why it pays to install and prepare the paperwork in advance. The eligible-cost start date for the new call will be set by its funding conditions.

Choose a system that fits both the earlier calls and the new model: plant and battery on the same site, a new CE-marked LFP battery, a hybrid inverter with a backup function, and a certified contractor who declares the installation to ESO. Keep the invoices, the equipment handover act, the contractor’s declaration, ESO’s ownership-boundary act, technical documents and photos of the installed system. We prepare the technical and warranty documents our customers need for the application.

Already have a solar plant? Adding a battery

The Ministry of Energy states that for residents who already have a solar plant but have not received support, it is considering allowing them to add a battery and apply for funding. This is not yet a decision – the terms will become clear with the funding conditions.

Technically a battery is added to an existing plant through a hybrid inverter: if your plant runs on a grid-tied inverter, it is replaced with a hybrid one, and the battery is chosen from that inverter maker’s compatibility list. Send us your inverter model – we will assess free of charge whether the battery can be connected to it or whether it needs replacing.
