About WEESS
WEESS GmbH offers energy solutions based on real projects: the portfolio includes the PowerTower system for distribution and physical metering of solar power per dwelling unit in multi-family buildings, the all-in-one energy storage system Zugspitze for private customers, the Zugspitze Pro hybrid inverter, the Bodensee C&I battery storage system for commercial and industrial applications, and the containerized large-scale storage system Nordsee for grid-serving applications. The range is complemented by the PowerSite Cube mobile storage system for construction sites and events, the Power Pulse real-time monitoring and control system, as well as trading and revenue share participation models. The customer segments range from the housing industry to installers and distributors through to institutional project partners. In the reference projects, tenant electricity systems with outputs between 10 and 52 kW and storage capacities between 10 and 232 kWh were implemented, including heat pump and wallbox integration. The project locations are exclusively in Germany.
