Tips on buying the right generator for your needs

Tips on buying the right generator for your needs

Whether it’s for a job site, your home or your business, a generator is a solid investment, but there are many generators on the market and knowing which one to buy can be confusing.  Here we will look at four ways to make sure you end up with the best generator for your needs.


  • Calculate the size you need:

This is the first thing you need to know: How much power are you going to need to run whatever you might need while the power is out.  One way to do this is to have a qualified electrician run a load test or to speak to an expert at a generator company, but basically, to calculate the size of generator you need to calculate the combined running wattage of all the appliances you want to run and then check what the starting wattages of these items are.  Select the highest one and then pick a generator that delivers at least that starting wattage.  Remember that appliances that use heat – heaters, stoves and so on use more power.


  • Fuel type:

Most South African generators run on diesel.  Diesel generators are long-lived, durable and don’t need much maintenance, but they can somewhat more expensive.


  • Noise and location:

One thing that can affect your choice of generator is where you’re going to install it and how much noise is allowed in that location.  For industrial clients or those using a generator at a work site, a larger, louder generator might be fine because the environment is already noisy.  If you’re in a residential area, on the other hand, a very big noisy generator that might need to run at night will disturb both your household and your neighborhood.  Generators generally should not be used indoors, including in garages – if they are, they need to be properly installed with a good exhaust, and not just place near an open window. Ideally generators should be kept outdoors and this is another thing to keep in mind when investing in one for the household use.  Noise reducing enclosures are available.


  • Fuel Tank size:

It’s important not to let your generator run out of fuel while it’s in use, so opt for a model that has both a reasonably large fuel tank and fuel gauge.  The fuel tank should be large enough to get you through a few hours of power outage, at least.  Another thing is to consider is how you’ll be able to get to your generator to refuel it
