HiTHIUM - global market launch

Founded in 2019, stationary energy storage manufacturer Hithium first began shipping battery products in 2022.

They asked for our support when they decided to enter the global market and launch a new global brand identity, introducing it worldwide starting at EES/Intersolar 2023 in Munich.

We were tasked in February 2023 with identifying, designing, and launching Hithium’s global brand in four months, with the new global website to go live in mid-May, a month before the EES trade fair.

With our expertise in brand-building, marketing, and communications in the renewable energy sector, we were able to take on this enormous challenge successfully.

We were aided by the clarity of Hithium’s requests, fast and agile workflows and decision-making, and their authentically open, cooperative corporate culture! In fact, that culture inspired the first iteration of the global brand identity. Through 2023 we built on the initial brand-building, website, and trade fair work together to provide Hithium with a full palette of marketing and communications support.

Marketing and PR for SMARTFOX

Households only use around 30 percent of the solar power from their roof themselves, the rest is uneconomically fed into the power grid. With the intelligent energy management system from SMARTFOX, however, homeowners can use up to 98 percent of their solar power themselves – and also save around 40 percent on heating costs.
The energy manager is compatible with devices from other manufacturers. And fits perfectly with the wallboxes and heating elements from SMARTFOX.

Renewable energies in municipalities

This brochure contains a selection of successful renewable energy solutions that are suitable for application in municipalities. Information on the most important sectors and the current state of the energy transition is explained, as well as different technology options and the possibilities for application in municipalities. The brochure also contains model projects that have been successfully implemented in Europe, the Russian Federation and Central Asia. It was produced in German, Russian and English.

New Energy World 2017 campaign

For the established industry congress Forum Solarpraxis | Neue Energiewelt we designed and implemented a B2B advertising campaign for print and online. The campaign was designed to activate both existing and new customers and encourage them to participate in the congress. In view of the large number of new competitor offers, the campaign was intended to present the conference as both a self-confident industry leader and “original” on the one hand, and to emphasise the innovative and new on the other.

Advertising motifs of the campaign

Since the majority of the competing events have a similar mix of topics and even identical speakers, we have opted for an emotional approach that ironically focuses on the real reasons for attending the conference. The informal ultimately beats the concrete transfer of knowledge or the obligatory look into the future becomes a look into the glass ball. The motifs trace the themes exaggeratedly, without completely tilting them into the grotesque – even if it seems absurd, the protagonists could still be serious about it.

The various motifs were implemented both as print ads and as banners in various formats and sizes.

Cover TESVOLT image brochure

Tesvolt Marketing Concept

For the young German battery manufacturer Tesvolt we created a comprehensive integrated marketing concept and implemented it with a bundle of measures. This includes a corporate design, concepts for PR, website and technical marketing as well as an advertising campaign and ongoing support.

Corporate Design

The big goal was to create an unmistakable brand presence that would convey the fresh appeal of the start-up on the one hand and reflect the solidity and reliability of Tesvolt products on the other. The striking corporate design creates this arch with the help of its spring green/white/grey colour palette, which gives the brand a high recognition value. The consistent use of the corporate design from letterhead to trade fair stand to promotional gifts has paid off for the brand and helped to make Tesvolt known in the market within a very short time.

Advertising image campaign in print and online media

The aim of the B2B image campaign was to make TESVOLT known in the market and to anchor it as a premium provider. The ads are always written in the “If…, then…” style. The advertising motifs focus on photos of people (users) who were usually able to solve a specific problem thanks to a test memory. A semi-transparent green color gradient overlays the ad motif and ensures an unmistakable appearance and high recognition value.

In an extended version, the app can also calculate the actual savings potential and the internal consumption rate. The app is available for iOS and Android and can be flexibly adapted to your corporate design.


The user is guided comfortably through the APP by means of simple inputs and can thus get a good impression of the possible yields of a future PV system – even without any prior technical knowledge. The resulting interest benefits the provider of the APP directly as lead.


For the ambitious EU project “SmartFlex Solar Facades”, Sunbeam provides several services from a single source: We are responsible for pan-European public relations and supervise workshops in which the project results are discussed and solar prototypes are tested. Also the design for the SmartFlex marketing materials and the design of the website in a modern, responsive design as well as the content of the site is in our hands.

Using the SmartFlex software, architects can plan their facades simply and intuitively and then transfer the data directly to a production line. The first production line for tailor-made solar façades is located in Vilnius, Lithuania, in the factory of the solar module manufacturer Via Solis.
