Sustainable Swiss battery storage

Increase self-sufficiency, reduce costs, decrease CO₂.

Store solar power resource-efficiently.

The sustainable battery storage.

The intelligent storage solution for every home. Whether you are planning a new solar system or retrofitting an existing one, our system perfectly adapts to your needs.

Use solar power for your own needs instead of feeding it cheaply into the grid.

With modual, you store the solar power you generate yourself and use it when you need it. Our systems are quickly retrofittable, safe, and built to Swiss quality standards. Thanks to Second Life batteries, we extend the lifecycle of high-quality cells and reduce resource consumption.

Sustainability with Second Life

We give high-quality battery cells a second life. This conserves valuable resources, significantly reduces your carbon footprint, and makes a direct contribution to the circular economy.

The second life for electric car batteries.

Instead of scrapping EV batteries, we give them a second life as stationary home storage. This reduces the ecological footprint and increases availability. Each battery cell undergoes rigorous testing and is monitored with the battery management system (BMS) developed specifically for second-life batteries to ensure safety and performance are always guaranteed.
