Total system example
The W-SQ Pro 40 diesel generator extends beyond a standalone solution, serving as a key component in a comprehensive energy system when combined with power electronics and a battery bank. This integration allows for a seamless transition between diesel-generated power and stored energy, creating a hybrid system that is both flexible and efficient. The generator’s robust performance is complemented by the battery bank’s ability to provide silent, emissions-free power.

The eco-friendly upgrade
Mobile power supply is typically facilitated by trucks equipped with substantial diesel generators. These generators can operate up to 10 hours daily, potentially using up to 300 liters of fuel. Moreover, the absence of aftertreatment in older models means diesel exhaust fumes are a common issue.
Conversely, a novel hybrid solution has been integrated into a Mercedes Sprinter. This system comprises a W-SQ Pro 40 diesel generator that meets the Stage V exhaust criteria and has a capacity of 35 kW, alongside a 32 kW LiFePo4 battery array. It allows for the direct use of up to 21 kW of power without the need for the diesel generator for a certain duration. When additional power is required, a cumulative output of as much as 56 kW is achievable.
Revolutionizing efficiency: cut costs and emissions
The WhisperPower hybrid system operates entirely on autopilot. The generator kicks in to recharge the battery bank as soon as it detects a need, ensuring the process is completed in the minimal amount of time.
The WhisperPower system has reduced our fuel expenses by more than 80%. Now, the W-SQ Pro 40 diesel generator is only needed for up to two hours a day during regular operations. We were astonished to find that, after an extensive day of shooting, we only needed to refuel with a few liters of diesel. Additionally, the absence of noxious exhaust odors is a significant improvement.

Hybrid system using the W-SQ Pro 40
A mobile power supply is indispensable when sufficient power is needed at the filming locations for a movie or series, especially as the location is often changed several times a day. It’s not just lighting, sound and camera equipment that need power… Catering for the film crew and actors is also a major issue.

The quietest generator in its class!
We supply the generator standard with a robust noise barrier. This shield consists of aluminum plating, equipped with heavy insulation material for optimal sound reduction. At a fixed speed of 1500 rpm, the W-SQ 40 Pro produces only 53 dB! Want to experience how incredibly quiet that is? Visit our test center in Drachten, Netherlands, take the hearing test, and you’ll be convinced!
Smart design: maintenance-required components are accessible from one side. Also available without a noise shield, ask about our open frame options.
Pure power, excellent service & adequate parts supply
All W-SQ Pro 40 generators are set up to automatically operate air-conditioning/ heating systems, heavy-duty tools, compressors, kitchen galleys, lights, refrigeration and cooling systems, computers and more. All at the same time, depending on the load
The ever growing global network of distributors and dealers take care of technical support and service.
