Choosing the right generator for your needs can be a confusing process if you’ve never used one before. Whether you need a portable generator for camping trips, power for your mobile business or a full backup power supply for your entire home, simply picking the cheapest option may leave you with limited power capacity and unable to run the appliances you need. Equally, overestimating your power requirements can mean unnecessarily high initial costs.
In many cases, to simplify the process, it is suggested that we calculate the wattage requirements of all the appliances we intend on running at any one time. To do this, you will need to:
- Create a list of everything you need to run at any given time
- Find the starting watts and running watts of those appliances – exact figures can be found on the appliance’s manual or identification plate, or online if you can’t find those. A wattage metre can also be used to check each appliance if you can’t find its information.
- Then, calculate the combined running wattage for all of the appliances you will be using at the one time.
- Finally, identify the appliance with the highest starting wattage and add this to the total running wattage of all appliances.
For example, we want to run a dishwasher, a 1,000watt microwave and a fridge at the same time so make the following list:
|Appliance||Running watts||Starting watts|
The combined running wattage of the three appliances is 3,200watts and the fridge has the highest starting watts at 2,200watts. So: 3,200 + 2,200 = 5,400watts. We can therefore look at generators with an output of 5,400watts or more.
It is however important to note that this can sometimes be misleading. If you have numerous appliances, how often will you be using them all together? Equally, with smaller generators it’s easy to go over capacity so often it’s best to choose the next model up as wattage does not increase in large increments from machine to machine – it’s only with large, commercial machines that going up a model will mean a big jump in wattage and therefore price. These various factors are why we like to work in a different way with our customers to calculate the wattage and consider all factors to ensure they get the best machine for their uses.
It’s always best to speak to an expert to determine how much power your generator requires and explore the most efficient generators for your application.
