The renowned Whisper range of marine generator systems and accessories, previously manufactured by WhisperPower for Mastervolt, will be sold directly by WhisperPower through its own network of dealers, distributors and agents from July 2010.

This announcement is part of a new long-term cooperative agreement between WhisperPower and Mastervolt. The agreement will also see WhisperPower manufacture the jointly developed GPX 5 kW variable speed hybrid generator system. Mastervolt will have exclusive rights to distribute the GPX worldwide in the marine sector, while WhisperPower will sell this innovative product directly to the mobile and off grid remote markets.

This new supply agreement between WhisperPower and Mastervolt, both located in the Netherlands, was made at the same time as Mastervolt’s co-founder and main shareholder Roel ter Heide agreed to sell all his shares in Mastervolt to the company. Although Ter Heide stepped down as managing director of Mastervolt in 2007 and started WhisperPower, he had remained a Mastervolt shareholder until now.

“The additional positioning of WhisperPower as a ‘marine’ company will strengthen its base and stimulate expansion in a broader market,” says Ter Heide. “We had already succeeded in gaining a substantial market share in global mobile and off grid/remote markets with the current WhisperPower product ranges. With our new Variable Speed hybrid power systems we are even better placed to become a leading player in these markets, offering added value by integrating power electronics and power storage as part of the entire system.”

WhisperPower is located in the northern Dutch province of Friesland, where it has a state-of-the-art premises in Drachten for development, assembly and logistics. Employing 40 FTEs, the company’s sales revenue since its formation in July 2007 amount to 14 million euro.

“WhisperPower’s mission is to change the world of power generation by developing quieter, cleaner and more energy efficient systems,” concludes Ter Heide. “We have made substantial funds available in order to achieve this ambitious goal.”
