Optimal Sound reduction
Our 27 kVA generators come standard with a robust sound-shield, with corrosion-resistant metal coating and heavy insulation material for optimum sound reduction. The soundproof design allows easy access to all sides of the generator and provides access to all maintenance-related components from one-side.
Units can also be delivered without a sound-shield. Ask for our open units with or without sound-shield.

DDC with optional 7" Touch Panel
A key feature of our 27 kVA generators is the 7 inch full color touch screen control that interfaces with WhisperCare. This allows full control over the generator system. The perfect solution for attractive visualization of immediate and/or historical information.
Pure power, excellent service & adequate parts supply
All our 27 kVA generators are build to automatically run air-conditioning/ heating systems, heavy-duty tools, compressors, kitchen galleys, lights, refrigeration and cooling systems, computers and more. All simultaneously, depending on the load.
The ever growing global network of distributors and dealers take care of technical support and service. Spare parts can be ordered from them or through shop.whisperpower.com.

24/7 Monitoring with WhisperCare 2.0
Our fixed speed 27 kVA generator can be monitored 24/7 in real-time remotely via the optional WhisperCare Wi-Fi router package. This is based on a combination of 4G/5G internet connection and WhisperTouch 7″ or 10″ monitor screen.
With WhisperCare, all important parameters can be read remotely using a mobile phone, tablet or computer. Plus, full Wi-Fi is now available for computers, TVs, and other enabled devices. The WhisperPower systems can also be connected to a variety of digital switching systems, each seamlessly integrated with Naviop, Yachtcontrol, Garmin, Trigentic, EmpirBus and more.
