The sonnen group, a portfolio company of eCAPITAL AG and the world’s leading manufacturer of energy storage systems, is acquiring shares in Energeticum Energiesysteme GmbH in Balzhausen.

The strategy also includes long-term, trusting, collaborative partnerships with sonnenBatterie centres and specialist partners on all levels – from lead generation to energy services.

‘By embarking on an even closer partnership with an excellent team that we know very well, we are guaranteeing higher customer satisfaction and the expansion of our position in Allgäu. Our collaboration with our partners is the foundation of our success, including on an international level, and we are already experiencing a strong start to 2018 with a high turnover,’ says Philipp Schröder, Sales and Marketing Director at sonnen.

Energeticum has been working exclusively with sonnen as a sonnenBatterie centre for Swabia/Allgäu since 2011, and has already installed several thousand sonnenBatteries in the region.

‘sonnen and Energeticum have enjoyed a long-term partnership. We have done pioneering work and built up the storage battery market here together from the very beginning. We are grateful for sonnen’s faith in supporting our plans to grow even further,’ says Robert Specht, CEO of Energeticum Energiesysteme.
