What is Integrel?
Integrel is the future of energy generation, completely replacing your stand alone generator!
Integrel uses smart new technology to generate up to 9kW of electrical power without compromising your engine’s performance. In fact, the system actively manages its output so that the engine is always running at its most fuel efficient. INTEGREL – Intelligent Generation of Electricity.
By using your engine for both propulsion and power generation, both tasks are delivered at optimum efficiency, resulting in fuel savings of up to 25%.
ONE ENGINE. TWO JOBS. LESS FUEL.
Integrel is completely automatic, working in the background with no direct input from you. It requires no maintenance other than a periodic belt change, offering substantial savings on fuel and maintenance costs across its lifetime.

WHAT DO I NEED TO DO?
Integrel is fully automatic and almost no user intervention is required. Simply start the main engine and it will start generating power. All of the information regarding your boat’s energy system is available on the dedicated user interface, including the amount of diesel fuel that you have in your tank.
When the engine is not running, all of the boat’s electrical systems automatically continue to be supported by the energy stored in the batteries; the more batteries, the greater the boat’s electrical autonomy.
When the batteries need recharging, a reminder appears on the screen indicating the battery level and advising that the engine should be started. The Integrel generator is so powerful, the engine only needs to be run at idle, or a little above, to recharge the batteries very rapidly.
Yes it is available right now. Systems are even more widely available NOW. We have many new distribution partners in more countries. Check out our Distributors Map.

The Integrel system is much more than just a generator; it is a complete power generation, storage, conversion and distribution system.
Focussing on the Integrel generator itself, this is manufactured specifically for Triskel Marine and is very different from a conventional high-power alternator:
- The generator will deliver its rated power continuously. For example, with an ambient temperature of 25C the generator will deliver a constant 8.3kW.
- The coupling of the magnetic flux between the rotor and stator has been dramatically improved to give very high generation efficiency.
- The windings have been changed to give the specific voltage range we need and to provide unusually high power output at low revs. With a suitable engine, up to 3.5 kW of output DC power is available at engine idle.
- The generator itself has no embedded electronics and much improved cooling air flow to cope with the higher power output.
- The customised engine mountings are specifically designed to minimise side loads on the engine, to eliminate shock loading and to maximise belt life.
- The control system is radically different from that of a conventional alternator (see next question).
Integrel is a complete power generation, storage, conversion and distribution system, deeply embedded in the operation of the vessel. To achieve this without compromising safety and to deliver ample electrical power automatically at all times requires a very smart control system.
The Integrel controller receives information in real time from multiple sources around the vessel (where available). This includes the engine ECU; the vessel’s on board data system, such as NMEA 2000; other proprietary data systems and Integrel’s own battery sensors and system components.
The controller uses this data to ensure that the engine is optimally loaded and that propulsion is never compromised. It also delivers the precise amount of power required to service the electrical loads and ensures that the batteries are kept in optimum condition. In the background, the controller also monitors key safety parameters such as battery and generator temperature, voltage and current limits and battery state of charge.
Because of the high power output from the generator, the load on the engine has to be managed very carefully. The controller checks that the engine is at its operating temperature before slowly ramping up the electrical power until the engine is loaded to its most fuel-efficient point. At the same time, the controller prioritises propulsion so if it senses a change in gear or a rapid change in engine revs, it shuts the generator down until the engine returns to a steady state. At high engine revs when the propeller uses all the engine power, or when manoeuvring at low speeds, the generator is also shut down.
Generator power output is calculated and adjusted 100 times every second to give a virtually instantaneous response to the constantly changing environment on board an operational vessel.
Power from an AC generator is quoted in kVA and power from a DC generator is normally quoted in kW. Integrel is a DC generator and so its power output is quoted in kW. The figures that we provide are the actual electrical power measured at the output of the controller, which is the amount of useable power from the system. To compare power quoted in kVA with Integrel’s output, multiply the kVA number by the power factor of the AC circuit, which is typically about 0.8. For example, this means that a 10kVA AC generator is equivalent to about 8kW.
A catamaran can have a system fitted to each engine but does not necessarily need it. The Integrel system is self-organising and is perfectly happy to run with two interconnected generators, sharing the load as needed with no user intervention. Two systems provide redundancy and balanced engine running hours; they can also charge multiple battery banks faster than a single system and can support high continuous loads.
A single system fitted on a twin-engine boat performs perfectly well but will take a little longer to charge multiple battery banks. If the engine is run in generator only mode when only one engine is fitted with an Integrel generator, it will accumulate more hours than the second engine.
The most obvious difference is that the Integrel system does not require a separate engine. This means that the fitting costs are less than for a stand-alone generator with no need for through hull fittings and no separate fuel, exhaust or cooling systems. Through life maintenance costs are also substantially less as Integrel only needs a periodic belt change; no more second engine checks and maintenance schedules.
Other key differences are that the Integrel system improves the fuel efficiency of the propulsion engine, reducing overall vessel fuel consumption. It is fully automatic, managing electrical power generation, storage, conversion and distribution in one package.
Integrel also allows you to reduce the size of your 12 and 24 volt house battery banks with its powerful battery to battery charging capability and reduces the size and weight of the cabling for power hungry consumers such as bow thrusters, windlasses and winches.
An Integrel system will replace a generator of up to about 10kVA. The Integrel generator itself is fitted directly on to the propulsion engine occupies very little space and weighs only 15kg. The storage batteries that it uses are normally fitted into the same space as the stand alone generator it replaces; a 10kWh lead acid battery pack for example measures 600 x 600 x 350mm and weighs 260kg. Lithium ion batteries have about the same volume depending on the supplier and are less than half the weight.
What if I already have a large 12v battery bank, inverter, solar and it’s working pretty well. Can I replace my 180 amp alternator with this system? So I would have a small 48v bank and a large 800-1000AH 12v bank. Also will my 12 volt bank being charged by solar and my inverter (when on shore power or gen.) be able to charge the 48v bank?
You would want to reconfigure the batteries to maximize the 48v bank, as this will optimize the charge acceptance rate and reduce battery-charging times. You would then have a small 12v ‘buffer’ bank, maintained in a full state of charge by a Triskel 48v to 12v battery-to-battery charger. Your 12v inverter/charger will not charge the 48v bank so you will either need a stand-alone 48v charger, or a 48v inverter/charger, both of which Triskel can supply.
Yes, there are high quality 48v solar regulators available. Using the solar array to charge the main battery banks directly is a good way to use the energy and it can then be trickled down to the house banks via the battery-to-battery charger.
What if I have a large generator that I am constantly under loading. Can I put this on the generator motor? Would that even make sense?
Now that I have a 48v battery bank can I install an Elco electric motor connected to its own shaft and prop as a get home engine? It would be used if my prop or shaft on the main was fouled or damaged. I would put the main in neutral and use the alternator to run the Elco motor. Would that work?
No. Integrel generates a lot of power at low engine revs. This optimises engine fuel consumption, which keeps the fuel bills down and ensures that the engine is properly loaded even at low revs. Your main engine becomes an optimally loaded, fuel efficient, stand-alone generator.
Without Integrel (or a stand alone generator), most cruisers have to run the main engine at anchor to charge the batteries from a conventional alternator; this does not load the engine optimally, is an expensive way of producing power and is not good for the engine due to the light load.
No. Mixing battery types will result in incorrect charging and potential battery damage. Ideally all batteries should be installed at the same time, be from the same manufacturer and be of exactly the same type. They will then charge and discharge consistently, balance correctly and achieve the longest possible life.
The Integrel control system supports both advanced lead acid and some brands of lithium ion batteries. We will advise on battery type when helping you to specify your system.
The key factor in selecting batteries is that they must be capable of high charge rates in order to minimise the amount of time taken to recharge and to make the most of the high power output available. The Integrel generator is software limited to 170A and 9kW allowing us to charge a typical 48v bank at the 1C rate, which is the amp hour rating normally quoted by the battery manufacturer.
Basically, there are two core parameters, with the tougher one in any application being the determining factor:
- The maximum DC load between Integrel run periods. Typically, you want to calculate the worst-case overnight loads, which in many applications is air conditioning loads, and then, if using advanced AGM lead-acid batteries, double that for the battery capacity, and if using lithium-ion, multiply by 1.2, to establish a minimum battery capacity.
- The charge acceptance rate of the batteries. If the batteries cannot soak up the output of the Integrel system you lose a lot of the benefits of the system. You really need at least 10 kWh of lead-acid batteries to optimize the system, and even then the charge acceptance rate will taper off once the batteries are much above 50 percent charged. With lithium-ion, we like to keep the charge rate no higher than the 1C rate, which is a charge rate equal to the rated capacity of the batteries, so a ~7.5 kWh battery capacity rating fits nicely with the 7-8 kW output of the Integrel system.
The inverter should be sized to meet the peak AC load. This is not the sum of all of the possible AC loads but the sum of the loads likely to be on at the same time. For example, an electric cooker will draw up to 5kW; an electric kettle 3.5kW; a fan heater 2kW; a hair dryer or a water immersion heater 1.5kW. It is unlikely that all of these will be on at the same time so a boat fitted with all of these devices would probably need a 6 or 8kW inverter. The inverter will draw power directly off the 48v system, 8kW being 160A at 50v, which is well within the capability of the system.
We use DC because it allows us to generate useable electrical power regardless of the rotational speed of the generator. It is also very flexible in its management and directly compatible with battery storage. Most boats have DC systems on board and we can service these with a minimum of conversion losses.
48 volts was chosen as it is classified as “low voltage” and is safe to handle. If you accidentally touch a live terminal, it will not harm you. 48 volts also allows us to use relatively small diameter cables which are less expensive and physically easier to install.

What are the benefits for a cruising yachtie?
One of the major frustrations for yacht owners is having to power up the main engines for two hours a day just to charge the house batteries for simple things; running a small fridge, lights, water pump etc. There was no opportunity to consider the “everyday comforts” such as an espresso, making ice for an evening drink, hair dryer, laptop computers, longer hot showers or air-conditioning in those hot summer months when you are NOT hooked up to shore power in an expensive marina. The Integrel system is a game-changer for the boating industry that solves this problem.
In the past, there was only one option. A separate, noisy, expensive generator.
The problem was simple.
- Having a large battery bank that could supply the power needs for your comforts
- The ability to charge that battery bank
The Integrel Solutions team can help you solve this problem.
With the Integrel system and the “right-sized” battery bank, you can rapidly charge even the largest battery bank FAST.
We can help you calculate your power requirements for now and in the future, and guide you in selecting the right “package” of:
