Battery system powers coffee, lighting, and heating

Jan Willem Oversier, site manager at Dura Vermeer Infra Regional Projects, is enthusiastic about the new power setup on his project:

“We’re using a Dura Vermeer trailer equipped with solar panels, and we’ve installed four Wattsun modules to supply it with power. That electricity runs everything—from the coffee machine and lighting to the computers we use and even the heating. It’s ideal.”

A whisper-quiet alternative to generators

The benefits of this solution go beyond just emission-free energy. While many construction sites still rely on traditional generators—causing noise pollution and exhaust fumes—Wattsun provides a whisper-quiet work environment, as Oversier also notes:

“Like I always say: with a generator, you’re always surrounded by noise. You can’t hear your colleagues. The Wattsun modules are silent and create a comfortable climate inside. It’s perfect for a site manager trying to get work done.”

Flexible and sustainable power supply

Thanks to Wattsun’s portable and stackable battery systems, both mobility and scalability are effortless. This makes them a perfect fit for infrastructure projects like this one, where trailers and workspaces move along with the job site.

On top of that, this solution significantly reduces CO₂ emissions—aligning perfectly with Dura Vermeer’s sustainability goals.

Curious how this emission-free power solution works in practice?
