Furthermore, the conventional housing lack efficient sound-proofing and has limitation to prevent sound pollution caused by the operation of the generator set assembly housed therein. Further, the conventional housing is difficult to handle. Furthermore, the conventional housing has limitation to maintain ambient temperature inside the housing under control and generator set assembly has limitation to provide cold starting and problems associated therewith. Furthermore, the conventional generator set assembly have ventilation fan driven by the engine resulting into less efficiency of the cooling package as well as more fuel consumption. Still further, the generator set assembly with conventional housing has limitation to give full rated output at higher ambient temperature. Still further, the conventional housings have limitation to provide efficient ventilation for venting out hot air generated during continuous operation of the generator housed therein.
Further, most of the conventional housings are made from sheet metal bend panels that have limitation to impart enough strength to the over-all structure of the housing and are comparatively bulky. Further, the conventional housings have

limitation for transportation to remote / difficult to access areas (i.e. having rough terrain, high altitude etc). Further, most of the conventional housings are with hinged doors which require comparatively considerable clear space for its opening. Furthermore, the conventional housings are subject to vandalism. Still further, the conventional housing has limitation to provide protection against ingression of undesirable moisture, warm air that may be detrimental for the delicate electrical equipment housed therein.

At low temperature and partial load, no fan is switched on thereby improving fuel efficiency. With this arrangement the generator set can be operated at wide range of temperature at rated load.
Referring to Figure 1 - Figure 6 of the accompanying drawings, the housing 100 is illustrated. The housing can be used for accommodating generators used in residence, hospitals, hotels, malls, lighting towers, hydraulic pumps, battery charging units, repair and maintenance units, mobile communication stations, heating systems, all terrain auxiliary power supply, cellular applications, NBC filtration stallions, Digital surveillance systems, Intelligence and data analysis systems, Force fighting vehicles and the like. The housing 100 has a modular, scalable and compact construction, thereby requires minimum foot print. The housing 100 is scalable and may accommodate generators of varying sizes. The housing 100 is divided into an operative top compartment 20 and an operative bottom compartment 10. The bottom compartment 10 includes a frame structure and a plurality of composite panels 10a, 10b, 10c and lOd that may be assembled with the frame structure for enclosing and defining an interior of the bottom compartment 10. This structure imparts strength during handling, transportation & is less prone to vandalism. All the composite panels 10a, 10b, 10c and lOd are provided with toggle clamps 12 for facilitating assembly of the panels 10a, 10b, 10c and lOd to the frame structure for configuring the housing and removing the

panels 10a, 10b, 10c and lOd for quickly accessing the generator housed inside the bottom compartment 10. Such a configuration provides easy access to all maintenance points of the generator without loosening any bolts, thereby reducing the maintenance time. The front panel 10a, and the right hand side panel 10c is provided with louvers 14 for facilitating ventilation of the interior of the bottom compartment 10. Further, the side and top panels of the top compartment 20 are also provided with louvers 19 for facilitating cooling of engine coolant passing through radiator 20. More specifically, the air heated due to continuous operation of the generator escapes through the louvers 14 configured on the housing 100. The louvers 14 are configured on steel fabricated panels that are secured to the housing 100. The housing 100 is further provided with lifting eyes for facilitating lifting and handling of the housing 100.

More specifically, the housing 100 is provided with telescopic slider on which the generator is supported, wherein the telescopic slider may be withdrawn for accessing the generator for facilitating maintenance of the generator. Such a configuration of the housing 100 facilitates convenient servicing and maintenance of the generator housed therein without affecting existing setup. Further, such a configuration of the housing 100 helps to take out the generator for a specific distance for maintenance purposes and push the generator back inside the housing 100 once maintenance is over. Accordingly, such housing 100 finds use in areas where space is an issue such as vehicle mounted generators and places where carrying out maintenance from the side doors of the generator housing is restricted because of pre-existing equipment.

The bottom compartment 10 generally houses an engine, an alternator, a control panel and a battery (not illustrated in Figures 1-8), whereas the top compartment 20 houses a radiator 22. Figure 9 illustrates the placement of the engine 15, the generator/alternator 16, the control panel 17 and the battery 18 inside the housing 100. In accordance with an embodiment, the battery 18 is a 12 V battery. The control panel 17 is mounted on the rear of the alternator 16. Generally, the control panel 17 has micro-processor based control units which monitors and controls the alternator 16. The Control panel 17 is compact in size being it's input power moulded case circuit breaker (MCCB), current transformers are housed inside Alternator's terminal box. Alternator 16 is having innovative design with smaller length and slightly bigger diameter. This further reduces the housing overall length as Alternator length is one of important criteria in deciding the length of generator set assembly .. The battery 18 is a vented lead acid (VLA) battery mounted besides the engine 15 for providing DC auxiliary supply to the generator/alternator 16. Necessary precautions are taken to minimize Electromagnetic conducted emission. The generator 16 can operate under three different modes of operation, the auto mode, the manual mode and the by-pass mode of operation.
In the auto mode, in the event of mains failure, the diesel generator (DG) controller detects failure and gives start command to the DG, i.e. remote start. The controller monitors and controls the DG set. During any abnormality i.e. low lube oil pressure, high water temperature, over speed, over/under voltage, DG over load etc., it trips the DG set. After attending/ rectifying the fault, the DG set can be taken into operation. In the manual mode, the DG set can be started and stopped for the DG controller. In this mode also it monitors and controls the DG set. It protects the DG set in the event of any abnormality. In the bypass mode, the DG set can be taken into operation "bypassing the DG controller", such kind of feature is required when generator is being used in critical applications e.g. fire fighting equipment, hospitals etc. The generator is capable of performing, when operating conditions such as operation temperature is in the range of -20 degree centigrade

to +55 degree centigrade and storage temperature is in the range of -30 degree centigrade to + 70 degree centigrade, relative humidity is in the range of 95 percent at 40 degree centigrade and altitude is 4160 meters above Mean sea level (MSL) in operation and 9100 meters above MSL in storage.
