About Wattando

Wattando GmbH develops solutions that enable installers to meet the high demand for PV and storage systems more efficiently than before. For this purpose, Wattando offers the energy management system "Wattster", which enables the simpler and faster integration of classic solar systems and storage units - and this for systems with a power spectrum of 1 kilowatt to 44 kilowatts. The numerous structural changes to electrical installations, juxtaposed with an ever-increasing shortage of skilled workers, are considered one of the major obstacles to a broad-based energy turnaround. Wattando was founded by Boris Klebensberger, former COO of Solarworld AG, and Stefan Ulfert, digital product and marketing strategist.

Wattando is part of the de:hub network, the digital ecosystem for startups of the German Federal Ministry of Economics and Climate Protection, as well as part of TELEKOM TECH BOOST, Deutsche Telekom's startup program.
