Small diesel generators – which are basically miniature versions of full sized diesel generators and function as such – are used not only as primary power sources but also as standby/back up power sources. Considered to be the best engines available, diesel engines are popular because they are efficient and generally maintenance free. While – as will be discussed later – they do cost more to purchase at the outset, their reliability and low maintenance costs inevitably make up for the extra money spent and remain more cost effective.
Diesels have no ignition systems, carburetors, nor spark plugs. Small diesel generators are simple in design and extremely durable and with few exceptions, properly serviced diesel engines will run for years and years before needing an overhaul.
The industrial-quality diesel generators, many of which now have Chinese origins with China being the industrial powerhouse of the world, are generally dependable, quiet and reliable, functioning at peak performance for many years, producing full-rated, clean and stable power.
The power created by a small diesel generator in the home is ideal as it won’t destroy home PCs, audio components, VCR, etc. It’s the kind of power that’s suitable for a home, office, and shop. It will produce that power on about half the amount of fuel that would be required for a same-size gas generator. The small catch to using 12v small generators, the type of which is required by the average homestead, as mentioned above is the extra expense at the outset. In the long haul, diesel wins every time. When you figure in the fuel savings and replacement costs for the several gas engines that it would take to equal the life of a diesel, the higher price of the diesel generator becomes insignificant. diesel generator set
Used generators, especially used diesel ones, are just as good as brand new generators if still functioning correctly. If you are not well acquainted with the workings of these generators, then it is always a good idea to have somebody knowledgeable check it out first. Older generators will often have very complex and possibly malfunctioning voltage-regulating hardware that can cost more to straighten out than the machine is worth. And remember, don’t buy a generator that is capable of producing way more power than you need.
Diesel engines are always priced considerably higher than similar-horsepower gas engines, and that price is of course reflected in the price of a diesel-powered genset. If the engine is cleaned of oily build-up on a regular basis and any leaks or other irregularities are easily spotted. Regular, timely oil changes are essential, as is the use of oil rated for diesels. Diesels operate at a much higher combustion pressure than do gas engines, and regular motor oil won’t stand up to the job. Small diesel generators have come a long way and truly offer a great solution to many problems you could face.
