  • Patent number: 12060826
    Abstract: A containerised generator set comprises a generator arranged within a container having a first aperture through which cooling air is exhausted in use. A pair of first doors are arranged to pivot outwardly on either side of the first aperture, with a removable wall being removably mounted between the first doors and spaced apart from the body of the container by the first doors from its lower end region to its tipper end region in its mounted position. The removable wall and the first doors define an exhaust air duct which preferably includes a sound absorbent material. The exhaust air duct extends for at least most of a total height of the body of the container to attenuate noise from the generator. Exhausted cooling air flows upwardly from the open upper end of the exhaust air duct and away from the immediate operating environment.

  • Patent number: 9584055
    Abstract: A voltage regulator system for regulating an output voltage of a genset includes a voltage regulator for reducing terminal voltage in response to a reduction in terminal frequency. A plurality of under-frequency roll-off (UFRO) states is provided in the voltage regulator, with each UFRO state being configured to implement a UFRO characteristic. An operational signal indicative of an operating condition of the genset forms the basis for selection of the UFRO characteristic.

  • Patent number: 9371953
    Abstract: A base made of a composite material supports a generator assembly. The base may support a number of components of the generator assembly, including an alternator, an engine, a control panel, a fuel tank, and a lifting frame. The base may include first and second tiers that are in two different horizontal planes for mounting of the alternator on one tier and the engine on the second tier, with a drive shaft of the alternator being aligned with a drive shaft of the engine. The base may include ribs extending from an under side of a support surface of the base in order to distribute loads and withstand stresses that result from the weight of the generator assembly.
