Properly Sizing a Home Generator – an Important First Step for Edwardsville, MO, Homeowners

Home Generator Edwardsville MOIn Edwardsville, Missouri, we experience unpredictable and often harsh weather, including strong storms and high winds. So, you never know when a power outage may occur. If you’ve decided to prepare for this eventuality by having a backup generator installed, you can begin the process by following these steps to determine accurate home generator sizing.

Determine What Will Require Power During an Outage

The first thing you should do is walk around your home and figure out what you’d like to keep power running to. Is it just your lights and HVAC system? Do you have any necessary powered medical equipment? Would you like to maintain power to your entire home during an outage? Be sure that you don’t leave anything out during this step.

Figure Out the Total Power Requirement

This is the most important step in home generator sizing. Determining the total wattage of components that will require power during an outage will help you choose a system with the correct capacity. Be sure to account for the power required to start and run all of your equipment. Once you’ve arrived at a total, you should purchase a system that has a slightly higher capacity than you will need. A good rule of thumb is to get a generator with 1.25 times the required capacity.
