"Sweetwater Electric installed my Generac whole house generator. Part way through the installation, we discovered a problem with the landscaping and placement of the generator. Sweetwater was patient while we worked out the issue and resumed work the day after the landscaper left. Alan and Thomas worked well together as a team and finished the installation without a problem. I would highly recommend them for your Generac, or general electrical, work. They are conscientious, hardworking, amenable and clean up after the job is complete. What more could you ask for?"

"We have had Andy do a couple of electrical projects for us. Reasonably priced. Quality Work. He tested running the generator and made sure the electrical systems in the house were running on the new generator after the electrical upgrade. Highly recommend."

"We hired Lighthouse Electrical to install a generator interlock kit for our house and am very impressed at how smooth everything went. They were the cheapest out of 5 quotes, but didn't cut any corners. Corey came out on site for a quote which added comfort that he won't try to extra bill us once the work was to be done, and we got the install scheduled within a week from calling. Christian came out to do the install and once everything was complete he vacuumed up and walked me through how to use the switch. As a cherry on top, they didn't add a surcharge for paying by credit. I couldn't be happier with the experience."

Generator Install questions, answered by experts

A portable generator can supply power to selected appliances and circuits in a home, but it's generally not designed to handle the entire household's electrical needs simultaneously. Portable generators have limited wattage capacity, so they are only designed to power essential devices and electronics temporarily until local power is restored. If your power needs outweigh the capabilities of a portable generator, consider installing a whole-home generator instead.

In many cases, yes. There are models called dual-fuel generators and fuel switches, but only between certain types of fuel. For example, with the right setup you can convert a generator from natural gas to propane. Some allow switching between diesel and gasoline. There are even tri-fuel generators available in some cases, which adds a large layer of security if you are worried about fuel availability in times of crisis. Always check your generator capabilities and manual instructions before trying to switch fuels. Some generators can use another fuel but may need a fuel conversion kit to prep them first.

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.

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.

You can expect a diesel generator to last for up to 30,000 hours of use, which works out to 20 to 25 years with the proper maintenance, of course. That depends on how much you use it, so a diesel generator used for emergencies a couple of times a year will last a lot longer than a generator that takes over for a faulty electrical grid every month for a day or two.
