On the road to mobile three-phase power: a behind-the-scenes look with Wattsun’s engineers

At Wattsun, we are continuously working on the next step in mobile energy solutions. Right now, our engineers, led by Marnix Bakker and Peter Hoogervorst, are working intensively on an innovation that is in high demand from our customers: a fully mobile three-phase battery system. No fixed connection, no diesel generator, but silent three-phase power that you can use anywhere.

“The biggest challenge lies in combining three-phase power with mobility,” says Lead Engineer Marnix. “Three-phase power normally means heavy, fixed installations. We want the system to remain mobile. Something you can move around, deploy at changing locations, and still deliver the power and capacity needed on construction sites, at events, or for use by, for example, defense or emergency services.”

That mobility is therefore a strict requirement in the design. The system must be easy to move in multiple ways, for example with a forklift, in a company van, or by rolling or lifting the battery system on site. At the same time, it must be robust, with safety and reliability as top priorities. Senior Hardware Design Engineer Peter adds: “We design this system for real-world use. That means it must be able to take a hit, work reliably in rain, cold, and heat, and be deployable day in, day out. Indoors as well. Just like our current systems, but at a whole new power level.”

We are also taking major steps forward in terms of functionality. The new three-phase battery system will include a UPS function, a start/stop system for hybrid use, can be used as a single-phase to three-phase converter, and can be monitored and read remotely through an app. “Continuity and energy security are crucial for our users,” says Peter. “Whether you are running machines or powering a temporary installation, downtime is not an option.” At the same time, Peter emphasizes that even a battery system with more features must remain plug-and-play. “With one press of a button and one screen where you can read and adjust everything.”

Development is already well advanced. “We are truly in the final stages of engineering,” says Marnix. “If everything goes according to plan, we will start a pilot phase within a few months. We are already looking for interested parties who want to test it with us in real-world conditions.” The full launch of the system is expected later this year.

What makes the development of this innovation even more special is the way the new battery system is being created. Peter: “It is incredibly educational to do this together with production partners, knowledge partners, and professionals from top companies in construction and infrastructure, the entertainment industry, and the emergency and safety sector. Their input and feedback are worth gold. I am really looking forward to entering the pilot phase with professionals in the field. Together we are working on a solution that will make a difference: a flexible, silent force on the worksite.”
