Maximum Freedom with Clean Energy

The Stack 3000 is designed for professionals who need access to clean, mobile energy anywhere. Thanks to its stackable and portable design, you always have a power source at hand. You can easily increase capacity without the hassle of cables or polluting generators. This gives you exactly the right amount of power, wherever you’re working. That makes the Stack ideal for industries like construction, events, and film production—where reliable and silent off-grid power is becoming increasingly essential.

Smart, Rugged, and User-Friendly

Wattsun founder and designer Koen Olieslagers explains:

“Our goal was to create a battery system that’s not only user-friendly and mobile, but also smart and durable in all weather conditions. With the Stack, you have power at the push of a button—anywhere. Plus, it’s portable and easily expandable by stacking. The top module automatically delivers power, allowing you to add or remove units even during use.”

In addition to these features, the jury also praised the robust housing and the ability to generate, store, and use solar energy simultaneously.

‘A Tremendous Recognition’

“This award is a tremendous recognition of our team’s hard work,” Koen continues. “The fact that a prestigious German expert jury values our innovation makes it even more special. Winning the iF Award is another step toward our mission: making sustainable energy available everywhere.”

We’ll officially receive the award and certificate at the iF Design Award Night 2025 in Berlin on April 28.

Lastly, a big thank you to Studio ManGo for their contribution to the design!
