Rethinking tenant electricity: scalable system solutions for apartment blocks
How hardware-based system solutions such as the WEESS PowerTower simplify tenant electricity in apartment blocks – without complex supplier models, and with high returns.

A multi-family residential building in 45470 Mülheim an der Ruhr was equipped with a complete WEESS solution featuring a split hybrid inverter, a 20 kWh Zugspitze battery system, a PowerTower, and a Wallbox. The integrated system maximizes solar self-consumption, provides reliable and sustainable energy management, and seamlessly combines clean energy with convenient EV charging.


System for distribution and physical metering within the building. PowerTower provides the foundation for implementing tenant electricity as a clearly structured building electricity supply in multi-unit residential buildings, with less administrative effort and without ongoing software and licence fees.

All-in-one hybrid storage system for projects where battery storage is expected to do more than just store energy - it also needs to deliver backup, control and full system functionality.

WEESS combines PV, storage, heat pump, and charging station into one smart system. More self-consumption, lower costs – for your home.
Let's explore how WEESS can turn your building into energy infrastructure.
