"Brett did an excellent job for us. We had the outside meter box and cable replaced. Brett gave us a great price, communicated quickly and got the job done when he said it would be done. The town just stopped by to sign off on the job and they said that the job was one of the best that he’s seen. We also had Brett put up two ceiling fans on the porch, he made sure that they were operating perfectly. Don’t hesitate to contact this company for your next electrical project"

"The solar company I chose was one of the worst choices I have ever made. Vision Solar went Bankrupt and I had no one to help me when my system went down. I call numerous solar companies and no one would help me. Then I found Phase Out Electric it was an immediate yes after I told them what was going on. My inverter was bad and still under guarantee and they took care of getting it for me. I was kept well informed on what was happening. I will use them again if I have any more problems."

Generator Install questions, answered by experts

Yes. You can connect your home back-up battery to a generator with its designated charger. Be sure that the output of the generator matches the input requirements for the battery for best results.

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. 

Many services include assembling the unit and securing it in the window. Confirm with your provider.

When installed and used correctly, generators are safe to use. The most critical generator safety tips to keep in mind are:

  • Never use a portable generator inside an enclosed space, as the carbon monoxide exhaust it creates is lethal.

  • Never attempt to connect your generator to your home’s electrical panel independently; hire a professional for this dangerous job.

  • Never overload your generator by connecting more appliances than for which it’s rated; you can damage your generator and appliances or even cause a fire.

It’s usually better to repair your generator if it isn’t working properly, as it will typically be much more affordable and should yield similar results. Generator repairs cost around $300 on average, while installing a new whole-house generator costs around $5,000 on average. The only exception is if you know your generator is reaching the end of its useful life, usually between 30 and 40 years. If you have an older generator, you could face multiple repairs in the coming years, which might mean that a full replacement will be more cost-effective over time.
