What matters when buying Generators
Types of Generators
Generators can be broadly categorised into portable and inverter types. Portable generators are typically heavier and designed for use in a fixed location, such as during power outages or at job sites. These generators usually provide more power output and are suitable for running larger equipment. Inverter generators, on the other hand, are lighter and more compact, making them ideal for recreational activities like camping or use in caravans. They produce cleaner electricity with less harmonic distortion, which is essential for sensitive electronic devices.
Power Output and Capacity
When selecting a generator, it is crucial to consider the power output. This is typically measured in watts (W) and defines how much electrical power the generator can supply. Identify the total wattage needed for the devices intended to be powered. Continuous power ratings indicate the maximum power the generator can sustain over time, while surge power ratings show the temporary power available for starting equipment with higher initial demand. Ensure that the generator's capacity meets or exceeds these requirements.
Fuel Type and Efficiency
Most generators operate on petrol, but some models may use alternative fuels such as diesel or propane. Petrol generators are common due to their availability and ease of use. However, consider the efficiency of the generator, as this will affect running costs and convenience. The fuel tank size also impacts how long the generator can operate before needing a refill, which is particularly important for extended use during trips or emergencies.
Noise Levels and Portability
Noise reduction is a significant factor, especially for recreational use or in residential areas. Generators are rated for noise levels, usually expressed in decibels (dB). Inverter generators tend to operate more quietly than conventional generators. Portability features, such as weight, handles, and wheels, should also be considered. A lighter and more compact generator will be easier to transport and store, making it more convenient for outdoor activities or emergency situations.
