How to select a suitable generator for you?

Generators are usually chosen based on their maximum and rated power. One must calculate what the total load will e in order to effectively choose the proper generator. Some appliances and equipment require a higher starting wattage and then it tapers.

Rule of thumb is to take the running wattage and multiply by 3 unless the appliance or equipment is under a constant load such as light bulbs.
Click on Amps, Watts, Volts and Kilowatts for the formula to calculate wattage. Otherwise use the charts provided below.
You can use our Wattage Chart below to estimate the wattages of the tools, appliances and motors you will be operating at the same time. Add up the wattage of the tools, appliances and motors you will be running at the same time.
Then, select the generator with the continuous wattage rating that meets or exceeds your total load.
How to choose an Effective diesel generator?

The cheapest operating costs are for Gas fueled generators. In sizes up to 100 KW Gas generators can be up to 30% more expensive than Diesel fueled generators with the same output. If Gas is available and you are going to operate your generator for more then 2000 hours a year, this can be the most cost effective solution Gas is also much more environment friendly.

Kerosene engines are not expensive to buy and have comparatively low running costs. They are limited in output generally not exceeding 5KVA.
An additional advantage in using Kerosene fuel is that it is less volatile and thus much safer than Petrol. Petrol Engines are the cheapest to purchase and the most expensive to operate. If you need a Generator to operate for up to three hours a day, they are a good choice. In general, Petrol fueled generators are limited to maximum output of 20KVA and minimum speed of 3000 RPM.

Diesel Generators are commonly available with outputs from 5 KVA up to 2500 KVA. They are significantly cheaper to operate and maintain compared to Petrol,
but more expensive then Petrol engines.
If you need a generator for more then 3 hours a day, or a minimum of 1500 hours annually, it is recommended that you to buy a Diesel Generator.
Diesel Generators are machines that generate electricity.
The two main components of the diesel generator are the engine which supplies power and the alternator that turns power into electricity.
Choosing the right diesel generator may look like a difficult task, but choosing the right one can give you the most efficient and most effective diesel generator for you. First is to identify the tools and appliances you want to operate with your diesel generator. Next is to determine the required power for each item.

Then add the required watts of each item that will be running all at the same time.
Last is choosing the generator that has rated watts that exceed or meet the total power required for the tools.
Another important thing to keep in mind is the Motor Starting. Keep in mind that induction type motors, like those that run sump pumps, refrigerators and compressors , typically require 2 to 3 times their listed running watts to start.
