Recommended portable diesel generator for the home use. Exploring features and benefits of the best small diesel generators, including All Power America, ETQ, Champion....

Small diesel generators are mainly designed for home use in a case of emergency blackouts or for the construction site, where power is not available. Diesel generators for home use are temporarily connected to power appliances, electrical devices or even the whole house.

Advantages

  • Engines that are used on small diesel generators are consuming less fuel than engines on gasoline generators.
  • Portable diesel generator has the operating cost lower.
  • Diesel generators last longer.
  • Diesel engine has fewer elements so the maintenance is simpler and cheaper.
  • Diesel engine is more reliable than gasoline.
  • Diesel engine can produce more power as the compression ratio is higher. This engine compresses the air only, while the gasoline engine compresses the mixture of the fuel and air.
  • It is easier to obtain this fuel during the power outage than gasoline.
  • It is the least flammable fuel source.
  • Fuel home delivery is available.

Disadvantages

  • There are also disadvantages of diesel generators for home use, when comparing to propane or gasoline generators.
  • Diesel has a shorter shelf life when comparing to propane (longer when compare to gasoline).
  • It is harder to store diesel (needs bigger storage tank) and obtain during the hurricane season, than propane.
  • The engine is noisy - noise level is higher (check the level in dB).
  • These generators are built heavier (but stronger), so it is harder to move them around.
  • Pollution on the environment is higher than for unleaded gasoline or propane types.
  • Expensive.
  • Combustion gases are hazardous on your health.

Buying guide

  • Buy a generator that uses a four cycle, liquid cooled diesel engines as they are quieter and less prone to overheating.
  • Look for the diesel generator that comes with the muffler, low oil alarm and shutdown.
  • As they are heavier than gasoline, wheels and handle are must for easy transport.
  • In order to provide easier starting during the cold weather and during cold starts, installed preheater is recommended.
  • Starting system with the electric starter (preferably with a remote) and backup recoil starter is great to have.
  • If planning to use a small generator for a cabin in the mountains, check the altitude in specs.
  • Recommended noise level for most of the portable diesel generators is 75 dB - 80 dB... lower is better.
  • Make sure that your product is in compliance with electrical safety standards (UL, CSA).
