SolarCloud is the next digital product to arise from the cooperation between Kiwigrid and the innogy Group

  • SolarCloud makes it possible to store the solar energy generated in summer for use in winter
  • The Kiwigrid platform is the IoT- and software-based backbone of this innovation



Virtual storage of solar power – now possible thanks to the innovative SolarCloud, which the Essen-based energy company innogy presented at Intersolar 2018. Kiwigrid’s energy service platform serves as the IoT- and software-based backbone of the virtual solar energy storage. When it comes to digital energy services, the Dresden-based company has been the strategic partner of innogy and the enviaM Group since last year.


Today, many customers rely on energy storage systems to enable them to use their self-generated solar power more flexibly. However, physical storage devices hit their limits if, for example, they are tasked with storing the solar energy produced in summer for use in winter. After all, the electricity that’s produced in summer would be an ideal supplement to the self-generated electricity during the dark winter months when PV systems produce almost no solar power on some days.


The heart of SolarCloud: the Kiwigrid platform


This is precisely why LEW led the charge in developing SolarCloud for innogy and enviaM, which enables virtual storage of solar energy. The Kiwigrid platform is the IoT- and software-based backbone of SolarCloud and the home energy management system solutions of the entire innogy Group. “We combine the solar system, energy storage, and SolarCloud into one smart and customer-centered system. We will continue to develop the product further in conjunction with innogy and the enviaM Group”, adds Tim Ulbricht, Managing Director of Kiwigrid.


The Dresden-based company specializes in connecting and orchestrating many small-scale distributed energy resources to form one system and already manages millions of data points of connected decentralized devices on its platform. This is Kiwigrid’s basis for its numerous services, which include system integration, installation support, and strategic consulting.


Martin Herrmann, Sales Director at innogy: “The sun often shines most intensely when the electricity consumption in the house is at its lowest, namely at noon. Almost every second homeowner therefore supplements their photovoltaic system with a battery. Our virtual storage, which can also be used as a storage expansion option, now makes it possible for PV system owners to use the electricity generated on their own roof more effectively.”


Open system for easy integration of new devices


SolarCloud takes the solar products from innogy, enviaM, and LEW to the next level. Kiwigrid advised on the development of SolarCloud and implemented the appropriate business logic. All components are integrated and controlled via KiwiCloud and the KiwiOS energy manager. Since the Kiwigrid platform is an open system, integration of additional devices is possible at any time.
