"A wonderful experience for a complicated project! I would use Green Sun Energy again for any service they provide. They made the generator install as easy and painless as possible. The crew was kind and efficient. Lots to do for an install such as this but they did it quickly, efficiently and were extremely organized. Just how I like it! Thank you so much!! We feel protected for whatever comes our way."

"Kope Electric just finished installing a Generac generator at my house and their work was top notch. They actually got me in their schedule 1 week early and finished as timely as they said they would. I highly recommend them to anyone interested in a generator."

"I cannot recommend RYB Electric LLC and Sebastian highly enough! We hired them for several electrical upgrades, including: 1. A full electrical panel upgrade 2, Installation of a Level 2 EV charger, and 3. Installation of ground rods for extra protection Beyond his technical expertise, Sebastian is a pleasure to work with. He is incredibly easy to talk to, has a great personality, and took the time to answer all my questions without making things feel overly complicated. It’s rare to find someone who is both a master of their craft and so personable. The workmanship is top-tier—everything is neatly installed, labeled, and functioning perfectly. If you are looking for a reliable, skilled, and fairly priced electrician who truly cares about the quality of his work, look no further than Sebastian. We couldn't be happier!"

"We called PipeWorks for an emergency hot water heater replacement on a weekend. In approximately one hour, they had a technician, Pablo, at our house to assess the issue. Pablo was extremely professional and made safety during the COVID pandemic a top priority as he did his work. He was able to get us a replacement water heater and install it the same day and completed the job within a few hours of when he first arrived. He answered all of our questions, did a terrific job, and even called us later that evening when we had reached out through the main number with a follow-up question. We were so grateful for Pablo's expertise and professionalism."

Generator Install questions, answered by experts

Whole-house generators can run continuously for extended periods, even for weeks at a time (around 400 to 500 hours), as long as they have a sufficient fuel supply. However, this type of extensive use will increase wear and tear and can shorten the generator's overall lifespan. During long periods of operation, it's important to check and refill the engine oil as needed, potentially as frequently as daily depending on the model. If your generator uses a fuel tank, ensure it is kept full to prevent unexpected shutdowns.

You may need a permit for a portable generator if you’ll be installing a transfer switch for your primary residence or similar work. Otherwise, a permit for other uses may not be necessary. Check your local building codes or ask a local generator installer for more information about your local regulations.

A 10,000-watt generator can run a small to mid-sized central AC unit (typically up to 3 tons or 36,000 BTU) along with a few other appliances. However, larger AC units or additional loads will require a bigger generator. Consult a local generator installer to ensure you add the correct size generator to your home.

While the rating will tell you how many watts the refrigerator needs at the peak of its cycle, it requires additional wattage to start. At the bare minimum, you’ll need a 1,500-watt generator to get the fridge up and running after a blackout. A 2,000-watt generator should be sufficient for most home refrigerators.

If you’re deciding between a solar battery versus a generator for the best backup power solution, you can take a few factors into consideration. Solar batteries are quiet while generators can be quite loud. Generators have a lower up-front cost, but they require fuel and ongoing maintenance while solar batteries are more expensive but don’t have many ongoing costs.
