"Working with Smith Power Group, Inc. was a very rewarding and mutually beneficial experience. The owner, Carlton, sat with us and explained the entire process and answered all of our questions. The office kept us informed concerning the necessary paperwork, permits, etc. On the day of installation the crew arrived on time and proceeded to install our generator without issues. We highly recommend SPG."

"Ken was hired to put a sub-panel in the garage, but he notice that rain was getting in the main panel. I hired him to replace the service coming down the side of the house, through the meter box and then the main panel and sub-panel. He did a great job. He was clean and neat and he worked around my work-from-home needs to electricity. He did the service and main panel on a Saturday and I had minimal power disruption. He is friendly and knowledgeable. I would definitely hire him again."

"Fantastic work! They installed under-cabinet LED lighting in our kitchen, and it has completely transformed the space. The lighting is crisp, bright, and perfectly placed to illuminate the countertops and backsplash. The team was prompt, clean, and extremely professional throughout the process. Highly recommend!"

Generator Install questions, answered by experts

A 1,500 square foot home will likely need a 15kW to 20kW generator. When deciding on whole-house generator size, add up the total wattage of the devices that you’d like to continue running during a power outage. That way, you can ensure you purchase a generator that can power your necessary appliances or medical equipment during an electrical emergency.

Yes, in most municipalities, you will need a permit to install a permanent home generator, including emergency backup, partial-home, and whole-home models. Because these installations involve significant alterations to your home's electrical system and produce exhaust fumes, local governments often require a permit or inspection for safety purposes. A generator permit typically costs between $50 and $250, depending on your location. Your electrician or certified installer can usually handle the permitting process for you, but you will be responsible for the cost. It's a good practice to confirm with your installer that they will pull all necessary permits before work begins.

If you’re wondering if you can use your electric vehicle as a backup battery, it depends on whether your EV is compatible with bidirectional charging. This technology allows energy to flow both ways, enabling vehicle-to-home (V2H) backup power, vehicle-to-load (V2L) for appliances and camping, and vehicle-to-grid (V2G) to support the power grid. Compatible EVs convert stored DC energy into usable AC power, helping reduce energy costs and enhance grid stability while providing emergency backup power.

If you’re wondering whether gas generators produce carbon monoxide, know that natural gas generators do not produce carbon monoxide if they are functioning properly, as natural gas burns cleanly. However, if the generator malfunctions and the gas does not burn completely, there is potential for carbon dioxide to be produced. To prevent malfunctions, it's crucial to perform regular maintenance, including running the generator weekly and scheduling professional inspections every 6 to 12 months. Also, be sure to test your carbon monoxide detectors regularly to ensure they function in the rare case of the generator producing carbon monoxide.

Potential benefits of using a natural gas generator include reducing your carbon footprint, lower likelihood of carbon monoxide exposure, budget-friendly operating costs, and low-maintenance, continuous fuel supply. Some possible drawbacks, though, include higher initial installation costs, dependency on a natural gas supply, and installation complexity. Keep in mind that pros and cons will vary based on the type and brand of natural gas generator.
