The Company

WhisperPower was founded in 2007 for the manufacture and worldwide sale of diesel generators and related items, which had been sold until this point under the brand name Mastervolt. Since then, the company has quickly and successfully grown and developed especially in terms of innovation and quality.

In 2009 Hybrid Power Systems BV was founded to develop and produce combined hybrid power and propulsion systems for superyachts and commercial vessels. Since 2010, the product portfolio has been significantly expanded with products and components which form complete electrical systems for vehicles, vessels or locations which do not have (permanent) connection to the public grid. They can be assembled for plug and play solutions. WhisperPower has used its years of experience in developing systems containing a diesel engine to develop in-house, a new generation of power electronics. The product range covers power range options from 500 watts to 500 kW.



WhisperPower has years of experience in the field of combined generator/electronic systems with extensive knowledge of markets and applications. Our core competences cover the whole spectrum, needed to develop ‘hybrid’ style power systems.



Most of the manufacturing process is carried out in-house in our 5500 m2 building, located in Drachten, Friesland, the Netherlands. The building is a showcase for the very latest thinking in terms of energy-friendly sustainability and includes facilities such as solar cells and climate control based on an eco-energy recovery system. We save as much energy as possible in all our daily operations, using thermal storage for residual heat or power. Tours of these groundbreaking new premises are available upon request.
