WhisperPower's extensive product range covers both leisure and professional applications.

OctoPower Marine

Low emission power solutions for the marine market

OctoPower is an integrated single branded power solution for recreational or commercial marine applications. We have the ultimate plug-and-play solution at hand, from 3 - 48 kVA. The heart of the OctoPower system is a battery bank that feeds a WhisperPower inverter during silent time. This (lithium) battery pack is rechargeable from different sources, including a dock connection, solar/ wind generators, one or more boat DC alternator and a DC or AC WhisperPower generator.

OctoPower 3

OctoPower 3

Battery-based 3 kW power system

Designed for boats. Consists of one power electronics module and one or two Lithium battery packs. All components will have been pre-installed/mounted.

The OctoPower 3 is supplied as an easy plug and play installation, with connections to: AC power (land/shore) input, solar panel(s) input, connection to outboards or inboard starter battery. The maximum charge power from this source is 1 kW (100 Amps / 12 V or 50 Amps / 24 VDC). There are outlets for 230 VAC and (optional) 12 VDC. A 120 VAC 60 Hz output is also available.

Piccolo generators

3.5 kVA - 15 kVA Marine Generators

The Piccolo generator range of compact generators combines the latest diesel engine technology with a new way of producing electrical power. Instead of adding an alternator with fixed speed on the back of the fly-wheel, WhisperPower have designed a very compact permanent magnet alternator (PMA), located just behind the engine. As a result, these systems are much smaller and lighter compared to traditional generators. The generator RPM can be fixed to a position offering the optimal balance between RPM, output power, audible noise and vibration.

Piccolo 5

Piccolo 5

AC 4.4kVA (3.5 kW)

The WhisperPower Genverter© Piccolo 5 is the smallest, quietest and most powerful of its kind. Thanks to the electronic PMG inverter output, it delivers the ideal power quality for all your comfort equipment such as a washing machine, small air conditioning system, electrical cooking hob, battery chargers and inverter/charger combinations.

Unique engine
All Piccolo 5 models are fitted with a modern diesel engine designed by WhisperPower, entirely for the purpose of generating power the smooth way. The engine is cooled by a heat exchanger designed for indirect water-cooling. The circulation water pump is driven by a PTO (no belt). This WhisperPower engine operates between 2800 and 3600 rpm.

M-SQ Generators

13.75 kVA - 48 kVA Super Quiet Marine Generators

Over the past 20 years, WhisperPower M SQ generators have established a strong reputation as one of the most durable and reliable fixed rpm (1500/1800) generators in the world. These SuperQuiet diesel generators meet the challenges of commercial and high-end recreational marine applications.

M-SQ Pro 15

M-SQ Pro 15

AC - 13.75/15 kVA (12/12.5 kW)

Every M-SQ (Super Quiet) Pro 15 WhisperPower diesel generator is designed for non-stop, 1500/1800 rpm operation under harsh circumstances. They are robust, silent, compact and extremely reliable. All M-SQ Pro 15 generators are made in the Netherlands and tested during a 2 hours running period in one of the most advanced generator production facilities in the world, before distributed on a world-wide base by dedicated, service orientated, distribution partners.

Only the best 4 cylinder engines are applied: long lasting, reliable, silent engines, complying with EPA Tier 4 (USA standard) and Stage V (European standard). The engine is water-cooled and kept on a constant temperature via a heat exchanger.
