Founding
Sol Research GmbH

Based on all the preliminary considerations and many initial sketches, we founded Sol Research GmbH in January 2024. Several other startups and established companies with annual revenues of over €1 million participated in the company right from the start. Furthermore, we managed to find an investor during the founding phase who, in the spirit of a business angel, provided both the financial security for technology and hardware development and the necessary network and contacts.

EES Munich trade fair
World premiere PS 2,500

At ees Europe – Europe's largest and most international trade fair for batteries and energy storage systems – we will be presenting our newly developed Powerstation 2,500 from June 19-21, 2024.

We present our first prototypes on-site and demonstrate their functionality. With our replaceable batteries, robust design, and sophisticated app and backend concept, we impress both on-site and on the presentation stage. At the same time, we gather a wealth of invaluable feedback from countless discussions, which we incorporate into further product development by adding to the specifications.

End of 2024

Customer-oriented practical test
Powerstation 2,500 on the home stretch

By the end of 2024, development of the Powerstation 2,500 will be completed, and final testing in customer-facing applications will begin. This step is rather unusual for a startup, as it costs additional time and money without generating the much-desired revenue. However, for us as a high-end manufacturer of Made in Germany products, this is a given and underscores our own commitment to quality.

The product is continuously optimized in testing and any remaining errors are corrected so that the products that go to end customers when they go on sale are completely convincing from the very first moment.

Second quarter of 2025

Market entry
Sales launch of Powerstation 2,500

We will launch our Powerstation 2,500 in 2025. Invented and developed in Germany, manufactured in the Stuttgart region, and ready for delivery, customers can order our first product with 2.5 kWh capacity and up to 2500 W power for €2,000.

At the same time, we also offer the appropriate accessories - such as cables, brackets, PV modules, etc. - for the PS 2,500, so that a complete customer solution can be purchased from us.

Rounding things off, of course, is our app, which is available for download from day one, ensuring the full customer benefit is realized. Back and and the data models in back and have already been sufficiently enhanced through previous testing to generate added value.

Mid-2026

Further development
Expansion of features

Over the course of the year, we will be upgrading the electronics of the Power Station 2,500 to enable the feeding of excess energy into your own power grid. This will transform the Power Station 2,500 into the Balcony Power Station 2,500.

We also use artificial intelligence to learn from historical user data and weather forecasts. This data helps us optimally adapt energy consumption to variable electricity tariffs. The goal is, for example, to minimize grid consumption and maximize self-sufficiency.

2026+

Expansion & Specialization

With this successful market launch, we are focusing on expanding our portfolio. In addition to the Powerstation 2,500, we are developing additional battery storage systems with various capacities – for mobile applications as well as for larger stationary deployments. We consistently focus on backward compatibility, maximum quality, and the principle of modular expandability.

At the same time, our practical insights, data, and customer feedback continuously flow into the further development of the app, backend, and AI. Our goal remains: intelligent energy solutions that simply work – for both professionals and private users.

We are also looking forward to many exciting customer-specific projects in which we will use our know-how and passion to create outstanding, new and innovative products.
