Zero-emission power supply for construction, installation and industry

Published on 9 October 2025 Reading time : 6 minutes

A construction site that comes to a standstill because there is no mains connection available. An event that runs on a roaring generator that emits both noise and exhaust fumes. An installation job where consumption is temporarily too high for the local power supply. These are familiar situations that companies encounter on a daily basis.

Traditionally, this was solved with a diesel generator, but more and more organisations are finding that this no longer meets today's requirements. Noise pollution, CO₂ emissions, fuel costs and maintenance make generators a cumbersome and costly compromise.

At Van Dulst, we see that our customers in construction, installation and industry are increasingly asking for an alternative. As a wholesaler with decades of experience in tools and machinery, we always look for the most efficient and future-proof solution. That is why we have included Wattsun's mobile, emission-free power supplies in our range.

An alternative to the generator

For many companies, the switch from a traditional generator to a mobile battery is a logical next step. Whereas diesel generators were the standard for years, modern construction and installation projects require quieter, cleaner and more efficient solutions. The advantages of a mobile battery are immediately apparent:

  • Quiet operation: Wattsun's systems operate silently, instead of the constant noise of a generator. This increases concentration and improves the working environment, while also preventing noise pollution for local residents.
  • Emission-free and healthier: there are no emissions of exhaust gases, particulate matter or nitrogen oxides. This ensures a healthier workplace and contributes to the sustainability goals that are increasingly being demanded in tenders.
  • Flexible use: a mobile battery makes you independent of the mains electricity supply. You can start your project immediately, even at locations without a connection. As soon as mains power is available, the battery serves as a buffer and absorbs peak loads.
  • Efficient energy use: machines and tools often experience short power surges. A battery delivers exactly what is needed at the right time, instead of a generator running unnecessarily all day long. This means less energy loss and lower costs.

In summary, a mobile battery combines the advantages of reliability and power with the advantages of sustainability and efficiency. For companies that want to be ready for the future, it is an investment that pays off not only financially, but also socially.

Wattsun's mobile energy solutions

Van Dulst supplies the complete Wattsun range. This means we have a suitable solution for every situation.

The Wattsun Dock 3000 forms the heart of the modular Stack system. This compact unit delivers three kilowatts of continuous power and has an internal battery of 1.8 kilowatt hours. It can charge and discharge simultaneously and is easy to connect to solar panels. Its robustness and portability make the Dock ideal for smaller projects or as a mobile energy source in a service van.

For more capacity, you can expand the Dock with the Wattsun Pack 3000. Each Pack adds 2.3 kilowatt hours and the modules are stackable up to a total of eleven kilowatt hours. Thanks to hot-swapping, you can easily swap modules without interrupting the power supply. This allows you to build a customised system to suit the duration and intensity of your project.

When more power or endurance is needed, the Wattsun Ventus offers the perfect solution. This mobile powerhouse delivers five kilowatts continuously and can handle peaks of up to ten kilowatts. With a battery capacity of fifteen kilowatt hours and a robust, waterproof design, it is suitable for harsh conditions. The Ventus can be charged in a few hours via the mains or with solar panels and also functions as a UPS in the event of a power failure. This makes it an easy replacement for a traditional generator.

In addition to batteries, Wattsun also offers solutions for private power generation. The Wattsun Solarkit is ideal for equipping site huts, containers or service buses with solar panels. The kit is modular and plug-and-play, allowing you to quickly add sustainable power. For maximum flexibility, there is the Wattsun Foldable Solar. This 600-watt foldable panel can be placed anywhere and connects directly to the Dock or Ventus.

Applications in construction, installation and industry

The power of these systems is particularly evident in practice. A construction company working on an apartment complex in the city centre can get started right away with a Dock and a few Packs. During the day, energy is replenished by solar panels, and in the evening, the battery powers the lighting and tools. Everything runs quietly and without emissions.

An installation company that needs to test machines in an industrial hall can rely on the Ventus. Thanks to its high continuous power and large capacity, long-term testing is possible without the need for a noisy generator. The Ventus also offers the reliability of a generator for events, film shoots or temporary workplaces, but without the disadvantages.

In industry, where high power is often required, we are seeing batteries being used more and more to absorb peaks and relieve the grid. This allows companies to avoid expensive investments in infrastructure while working in a cleaner and more efficient manner.

Environment and future-proofing

The environmental benefits are obvious. Every hour you use a battery instead of a generator, you save CO₂, nitrogen oxide and particulate matter emissions. Noise reduction also contributes to a healthier and more pleasant working environment. The modern LFP batteries used by Wattsun have a long life span of thousands of cycles and are designed with safety and sustainability in mind.

Although the production of batteries requires raw materials, this is more than offset by the savings achieved during their service life. Especially when the systems are combined with solar energy, the balance is convincingly positive. For companies that are at the forefront of sustainability, this is an opportunity to distinguish themselves and comply with future regulations.
