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 it 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 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 Integrel generator, the load on the engine must be managed very carefully. The controller checks the engine is at 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.
