"The SES Team is phenomenal. They offer turnkey solutions that exceeded our widest expectations. We had remote ceiling fans installed where none existed, SMART landscape and home lighting installed to beautify the property that is WiFi controlled, and a gas and propane generator installed to keep us safe should electrical power be lost. SES has a team of highly technical and competent people who offer affordable, intelligent, practical, and high quality electrical services options that in over 40 years we've never experienced with any electrical contractor. Well done Forrest and the entire SES Team!"

"The gentleman who came out was very personable; however, I am not swayed by personality but by professionalism. There was a dropped neutral in one of my lines, among other problems. Rather than fix the problem, his solution was to bypass it and just run another line. I did not find that acceptable. and his quote was twice that of what I got elsewhere. My recommendation is always get a second opinion. He also tried to get me to replace the breaker box (>$8k), which did not need to replacement."

Generator Install questions, answered by experts

Sizing a generator is a careful process that requires calculating the electrical load of your entire house. You have to take into account every device you want to use and their wattage requirements, plus the wattage needed to start them, and look for a generator that can safely run all that at around 80% capacity.

In more practical terms, a small home can run on a 10,000-watt generator (and if you only want to power a few key appliances, much less than that). A mid-sized home may need something between 15,000 and 22,000 watts. Larger homes require 25,000 watts or more. 

While diesel is relatively stable, it won’t last nearly as long as propane and you may have to replace it if it sits unused for too long. Diesel can sometimes struggle to work efficiently or start engines during especially cold weather, so it’s not the best choice for every climate. Compared to fuels like propane and natural gas, diesel generators tend to be noisier and create more exhaust, which isn’t always ideal for home use.

A home that is 2,500 square feet will likely need a 20kW to 25kW generator. Consult your local generator installer to confirm the generator size needed to power your home before purchasing a new one. Be sure to consider how much power your necessary devices need to run.

Generators run on a variety of fuel types, ranging from natural gas to solar power. Keep in mind that fuel costs varying by type:

  • Natural gas: $2,000–$21,000 per year 

  • Liquid propane: $2,000–$21,000 per year

  • Diesel: $3,000–$20,000 per year

  • Gasoline: $500–$3,000 per year

  • Solar generator: $2,000–$25,000 per unit

  • Battery backup: $10,000–$25,000 per unit

To power a central air system during a power outage, the whole-house generator will need to be at least 5,000 watts, and this number will significantly increase for larger units. Check the specific wattage requirements of your AC unit to choose the right generator size. Consider consulting a generator installer to ensure your whole-house generator meets your electrical load needs.
