Include diesel generators in your search for reliable power sources, to back-up your electricity demand during emergencies. But, you don't have to wait for a new hurricane to hit your area. Numerous maintenance procedures carried by the electricity supply authorities impede on the access by private residents. Aging power grid causes many blackouts, often lasting for days. That's why every reasonable homeowner needs a back-up power supply, that can be run economically and without much fuss.
The choice of diesel generators available makes the selection process quite complicated. And when you consider that hardly anybody is conversant with the electrical engineering principles, no wonder many buys are resulting in a mismatch between the power demand and the generating capacity of the diesel generator. What follows is a waste of money firstly, because the purchase price is high, and secondly, due to the expensive maintenance costs and premature wear and tear of spare parts. High noise level, offensive fumes and excessive oil consumption may be a problem.
Having said all that, diesel generators have many advantages over their petrol counterparts. Major benefits include the following: - Long operating life (12,500 - 32,000 hours between major maintenance is needed) for liquid cooled diesel generators. - Cost of the scheduled maintenance is lower than for the petrol gensets, even the most reliable ones. - To generate 1 kW of electricity will cost you 38% less. - Low level of noise when operating at full capacity, especially, when high quality muffler is used.
Yes, whilst an average petrol generator will require an air cooled engine replacement after 550 - 1600 hours (depending on the brand) an average liquid cooled diesel generator will last many times longer; particularly low speed engines operating at 1800 rpm. Although diesel engines operating twice as fast, at 3600 rpm are not as durable, they are still commonly used in light-duty applications, such as portable power units; also in less expensive models. So, what are the critical criteria of selecting one of many available diesel generators for your home? Here they are, listed in no particular order:
1. There's nothing better, than a liquid cooled diesel generator, fully enclosed and operating with an efficient muffler. 2. Exchangeable air cleaners are a must. 3. Your generator must have low oil alarms and overload shutdowns. 4. To be on the safe side, add an extra 25% to the nominal output needed. 5. Check the length of warranty and availability of the spare parts and service.
Finally, which manufacturer should you choose? It all depends how much you can afford. If you have only $1,500 you can buy some cheaper models with lower output.5 kW. But, if you have more money, you surely should consider buying one of many portable Kubota diesel generators. Cost of a 6.5 kW unit is about $5,000. Other reputable brands like Honda, Steele or Pramac are also worth considering. Finally, remember that you're investing in your and yours family comfort and safety, in the long term.
