A generator module includes a housing arranged for mounting to a rear face of an internal combustion engine, a generator stator fixed in the housing, a generator rotor arranged radially inside of the generator stator, and a bearing arranged to support a radial inside of the generator rotor on the housing. The generator rotor may include a rotor carrier and a plurality of stacked plates secured to the rotor carrier. The bearing may be at least partially radially aligned with the plurality of stacked plates.

A standby generator includes a standby housing defining a cavity and an internal combustion engine. The engine includes an engine block including a cylinder comprising a piston, an engine housing at least partially covering the engine block, and a crankshaft configured to rotate about a vertical crankshaft axis in response to movement by the piston. The standby generator also includes an alternator configured to generate alternating current electrical power, a controller comprising a rectifier configured to convert the alternating current to a direct current and an inverter configured to convert the direct current to a clean alternating current electrical power, and a transfer switch configured to receive the clean alternating current electrical power from the controller and at least one of grid, solar, or battery power, and configured to supply power to an electrical load. The internal combustion engine, the alternator, and the controller are positioned within the cavity.

An electric generator protective cover has a protective cloth cover, a set of cloth cover bracket, and a plurality of fixing feet. The cloth cover bracket includes a central block located in the center of the top and four elastic supporting rods fixed to the central block. The protective cloth cover is jacked up through the central block and the four elastic supporting rods. One end of each fixing foot is connected to an elastic supporting rod, and the other end is mounted on an upper cross bar of an electric generator bracket. The electric generator protective cover has the advantages that the protective cloth cover is arranged, which can isolate dirt such as rain, snow, mud, and sand.

A genset module coupling assembly includes a cross-bar of a module chassis oriented orthogonal to an engine neutral axis of vibration defined by an engine mounted on an engine chassis, a first bracket coupled to the cross-bar on a first side of the engine neutral axis of vibration, and a second bracket coupled to the cross-bar on a second side of the engine neutral axis of vibration. The first bracket and the second bracket are positioned to minimize communication of vibrations from the engine chassis to the module chassis.

A genset enclosure includes a frame system, a plurality of side panels, a plurality of roof panels, a first connector, and a second connector. The frame system includes a plurality of interconnected frame members. The plurality of side panels are coupled to opposing sides of the frame system. The plurality of roof panels are coupled to a roof of the frame system and extend between the opposing sides of the frame system. The plurality of roof panels are oriented perpendicular to the plurality of side panels. The frame system, the plurality of side panels, and the plurality of roof panels together define an enclosure portion having a first open end and a second open end. The first connector and second connector are engageable with one another and are coupled to the frame system along a perimeter of the first open end and the second open end, respectively.

A standby generator includes an internal combustion engine, an alternator, and a controller. The internal combustion engine includes an engine housing, an engine block, and a crankshaft. The engine housing at least partially covers the engine block. The engine block includes a cylinder. The crankshaft is configured to rotate about a vertical crankshaft axis in response to movement by the cylinder. The alternator includes a stator, as well as a rotor that is configured to rotate with the rotation of the crankshaft to produce electrical power. The controller includes an inverter that is configured to receive electrical power from the alternator and output alternating current electrical power. The controller extends at least partially above the engine housing.

A control system for a standby generator includes a control box mounted in a standby generator enclosure with a control panel coupled to the control box that is selectively openable to provide access into the control box. One or more fasteners may be mounted to the control panel to selectively hold the control panel closed, and one or more generator control components may be mounted in the control box and operated by the control panel.

An outer casing includes an under panel disposed on a bottom surface, and the under panel integrally includes a reinforcing part that supports an engine. By the reinforcing part, strength and rigidity can be secured without using other parts, a height dimension of the reinforcing part can be suppressed to be low compared to the case of separately providing a support member as in the conventional art, and a generator can be made light in weight and miniaturized. In addition, since a structure is such that the engine is supported by one under panel, need of fastening the other parts is eliminated, there is no risk of generating a gap between the parts, and noise can be reduced.

A generator module includes a housing arranged for mounting to a rear face of an internal combustion engine, a generator stator fixed in the housing, a generator rotor arranged radially inside of the generator stator, and a bearing arranged to support a radial inside of the generator rotor on the housing. The generator rotor may include a rotor carrier and a plurality of stacked plates secured to the rotor carrier. The bearing may be at least partially radially aligned with the plurality of stacked plates.

An air filtration system is coupled to an inlet of an enclosure of or to a piece of equipment. The air filtration system is coupled to the enclosure at the air inlet such that air entering the enclosure through the air inlet passes through the air filtration system. The air filtration system includes a frame assembly. The frame assembly includes an outer frame and a support mesh. The outer frame is coupled to the enclosure. The air filtration system includes a door assembly. The door assembly includes a door frame and a door support mesh. The door assembly is received by and mechanically coupled to the frame assembly. The air filtration system includes filter media positioned in an interior of the air filtration system defined by the frame assembly and the door assembly.
