Generac QuietPack 55G
Watts Delivered since 05/10/07
|The Generac QuietPack is a low speed timing
belt-driven 5.5kw generator designed for RV service. It features
single-side service, single location connections, remote-controllable and is
one of the quietest generators I've ever tested.
It uses the Briggs &
Stratton Vanguard industrial V-twin 27 hp engine. Most of the lack of
noise is achieved by the simple technique of only running the engine at
about 2000 RPM. The two pole alternator is driven at 3600 RPM by means
of a guaranteed-for-life timing belt and pulley system.
I bought this generator for use with my concession trailer. I
needed a very quiet portable generator capable of supplying power to an
all-electric concession stand. This generator fit the bill perfectly.

|This photo shows the generator as it arrived. The service panel is off. The V-twin engine is to the left. Note that it is completely enclosed in sound damping metal.
|A closer shot showing several features. The oil change system is especially nice. After having cursed the drain plug locations on various generators, I have nothing but praise for this system.
|Another view showing yet more features. As can be seen here, the oil change hose is simply unclipped, the cap removed and the hose lowered into a suitable container.
|Here is a closeup of the oil change system.
|Here is where all the outside connections are made. Note the waterproof automotive-type connector for the remote controls. If you've ever fought to get heavy cables bent around to make the connections to an Onan, you'll really appreciate this battery connection.
|The control panel. Note the heavy welded studs and anti-vibration nuts used to hold things together.
|Here is a view of the fuel system. The fuel hose is simply pushed through the grommet, slipped over the fuel filter nipple and the clamp tightened. Note the superb Facet fuel pump. Very quiet and efficient.
|If you've ever camped in cold weather you've probably experienced carburetor icing. With older Onans you just lived with it. Newer ones have a damper that directs warm air to the carb. Of course, you have to go outside to flip the lever.
|Generac has a better idea. This photo shows the electric fuel cutoff that also serves as an electric carburetor heater. It applies heat right where it is needed - the emulsion tube. This deices the carb without the power hit that warm air causes.
|A view of the inside of the control box. Note the single point ground system. This greatly reduces conducted electrical noise. Also note the RivNuts that receive the fasteners. This device contains real threads. Much better than a punched hole and sheet metal screws like most manufacturers use.
|A closer view of the control box. Note the quality high temperature wiring.
|The generator cart is pictured above left. This is a shot of the electrical connections. I bypassed the internal breakers and installed an external breaker so that I don't have to remove the service panel to reset the breakers.
|Another view of the connector panel. The QuietPack comes connected for 120 volt output but can be re-strapped for 240. I have mine strapped that way. The panel features an RV 30 amp outlet, a 240 volt twist-lock and a convenience outlet.
|This shows the generator deployed at a concession event. It is powering the concession stand, a commercial refrigerator and my RV. It is quiet enough to be located right next to the stand. Note the outboard motor gas tank. This tank can be changed out for another without shutting down the generator.
