Types Of Generators And Their Maintenance Tips

A generator keeps the lights in the home in case of a power outage. Power obtained from this redundant equipment can charge a phone when camping. Have a backup generator to power the premises when not connected to the grid.

Type Of Generators Based On Application

Whole House Generator

A home standby generator keeps all appliances in the house running, the HVAC system working, and the lights on in case of an emergency. Connect the gadget to the existing fuel supply at home, including propane or natural gas. A backup power source enables the machine to run even without fuel at home. Such sources include gasoline, solar, and newer generators with intelligent systems to connect users to regular checks.

Portable Generator

These types use a combustion engine, just like standby generators, to produce electricity. Consider the use when in need of temporary electrical power and power lights and tools in remote construction sites. The models are helpful in a wide range of applications and come in different configurations to suit other uses. Use them for smaller commercial establishments, including shops and retail outlets, outdoor weddings, camping, and powering of agricultural equipment such as irrigation systems or bore wells.

Inverter Generators

Models in this category can be portable or whole-home generators. An inverter generator produces electricity in three phases and creates a high-frequency alternating current (AC). The power produced is converted to a direct current (DC) and a more stable AC output. Generators in this category help create clean energy, and for this reason, they are suitable for use in sensitive electronics, including laptops and phones. Such models also operate more quietly due to stable energy output.

Generators By Energy Source

Input energy sources are either a fossil fuel combusted in an internal combustion engine to produce rotary motion or a natural energy source captured and turned into action.

Fossil Fuel Energy Source Generators

Generators that operate on fossil fuels include

Diesel Fuel Generators

Diesel fuel is readily available, and such engines have long lifespans if adequately maintained. The affordability of an industrial power generator and the ease of the cold environment starting has necessitated their popularity. Always store the fuel in the tanks for durations not exceeding 24 months and limit the number of hours the model is operated to reduce harmful emissions to the environment. Avoid using the models in wet climates to prevent engine damage.


They are the most common types due to the availability of gasoline. Maintenance costs are minimal and such types are ideal for portable models. Use such for residential and commercial services. However, keep in mind their loud nature to prevent disturbing noise when using them inside the house or office. Store gasoline and use it for a period not exceeding 12 months. Use such on rare occasions, for instance, when natural disasters like hurricanes hit as they produce relatively high emissions.

Natural Energy Source Generators

Solar Generators

Solar generators make use of radiating energy from the sun to power them. Solar panels help in capturing the energy to facilitate charging the battery. A stored charge is used to produce electricity to achieve the final goal. An inverter comes in handy to change power to a more stable AC. Use such models when in need of minimal electrical requirements.

Natural Gas Generator

Generators running on natural gas tend to produce fewer emissions. Such models do not require containers to store fuels as the natural gas is conveyed through gas pipes. Regular maintenance makes these types of generators last long.

Proper Maintenance Tips For Generators

  • Maintain the cooling system and check the coolant level. Note the existing levels, especially during shutdown periods
  • Clean and filter the fuel annually. Diesel fuel degrades quickly through contamination by microbes and water—clean fuel annually in all generators except for standby models to avoid moisture attraction.
  • Test the battery to establish its current health status. Check whether the batteries are clean and assess the electrolyte level and specific gravity of the batteries.
  • Check the battery power, especially for standby generators. Ensure that the batteries are robust and charged enough for long-term use.

Run the generator once every week for 30 minutes when under load. Charging the battery, removing excess wetness, and fuel filtering are enhanced. Keep the inspection records and tests for future scrutiny.
