What size do you really need?

If you have made a decision to get a portable generator, then a basic question you might get from a shopper would be “What size of portable generator do you need for home use?”  However, the answer to this question would not very popular. The answer is, “It depends on many things”.

To continuously run this unit, you should have approximately 700 to 1000 watts.  However, if the compressor kicks in, then it needs some additional 1100 surge watts. So in total, it takes 1800 to 2000 watts to provide ongoing power to your refrigerator. As it settles into running watt requirement of 800, the difference of 1200 watts can then be used to power something else.  If you have a low to the mid-watt generator, then you can prefer to run your refrigerator most of the time and rely on it keeping itself cold with the doors closed, then unplug and switch the power to other needs.

The size of your portable generator mainly depends on the number and type of electrical appliances that you plan to run. Cooling and heating appliances like freezers and air conditioners consume a lot of power. You will require a huge generator to power such appliances. Whereas, if you want the generator to only power lights, then you can opt for a smaller generator. For the home appliances that have moving parts like pumps and fans, consume a lot of electricity at start-up but do not require a lot of power to continue functioning. So the first thing you need to do is to work out and analyze your total electrical load, using the power charts available online and then prepare the steady state load, such as appliances and lights, which you expect to operate at any time.
