Overview

Experience pure tranquillity on the water, with only the gentle sound of waves against the hull around you while knowing you cruise with energy independence. Harnessing the engine’s spare power, Integrel E-Power produces up to 9kW of energy (or 18kW in a dual system) that is intelligently stored in a 48V battery bank, replacing a standard generator. With a state-of-the-art power management system and a series of fail-safe measures, Integrel E-Power is much more efficient than a generator. Step into the future of boating, enabled by precision engineering.

Integrel E-Power 18 DE

  • 18 kW of power
  • 48 Volts
  • 25% Fuel saving
  • 100% Automatic
  • 77kg Weight
  • Minimal maintenance

Integrel E-Power 18 DE is designed for dual engine multihull applications, and delivers up to 18kW of energy generation, stored in a 48V battery bank.

Integrel E-Power monitors throttle input, so that in the event full engine power is needed for propulsion, the system instantly powers down. As soon as stable engine RPM is restored, Integrel E-Power resumes full power generation.

Integrating seamlessly into a larger powered electronics system, Integrel E-Power works quietly in the background, with little need for user intervention.

How it works

Technology

Integrel E-Power is a high efficiency, high-output, large-frame alternator. It is fitted to the front of an existing inboard diesel engine and collects the spare power generated to deliver up to 9kW (or 18kW in a dual system) of energy. Spare energy is stored in a 48V battery bank for later use.

Controlled by an advanced power management system, Integrel E-Power leverages the substantial power differential between an engine’s optimal efficiency load and the boat propeller’s load. The system meticulously regulates the variable load (over 100 times per second) and complements the propeller load to ensure the engine consistently runs at or near peak performance and efficiency. Consequently, the engine operates with peak efficiency at all times, delivering high energy output, while optimising fuel efficiency to its fullest potential.

Rest assured that Integrel E-Power allows your boat to run at full speed at any time. The system automatically monitors throttle input and will instantly power down if full engine power is needed. Once stable RPM is restored, Integrel E-Power resumes full power generation. The system’s added weight does not affect boat speed, as it remains tied to propeller speed with a modern, well-governed engine.

Dive into inspiring stories from boat owners who already have Integrel onboard and explore our exciting case studies!

We’re currently considering a new boat for an around the world cruise and Integrel would be mandatory for the build. Great concept, great products, great support.

To anyone thinking about replacing a generator or trying to decide if they want an onboard generator – call Integrel. Talk to them about their technology, cost, and installation. You’ll be happy you did!

Shaun Chaney

The technical support team were as impressive as any we’ve ever worked with. Since installation, they’ve been responsive to technical questions and provided excellent service. Excellent system, excellent company!

We are currently sailing the coast of Brittany and the Integrel is working perfectly. Every boat should have an Integrel!

After two weeks of cruising we are extremely satisfied with having Integrel E-Power onboard. Having a third crew on the boat, and we always get the same comments: just wow!

I'd like to report that Integrel E-Power is one of the favourite parts of our boat... It 'simply works' as advertised.

We’ve never had a moment that the boat is unable to make power.

Shaun Chaney

I can’t imagine any other system for our heavy electrical needs. With 5 passengers onboard and air conditioning 3 cabins every night (& watermaker, large refrigerator, electric galley) – Integrel E-Power performs flawlessly.

Even in winter conditions with freezing temperatures, running the Integrels for an hour or so has kept the batteries full for everything we need onboard."
