"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."

"Roy is the best. He spent 3 hours Saturday afternoon troubleshoot a mistake that previous electrician made, for a very reasonable price. Now the awning and front patio lights work, finally! Kids and wife happy. Hiring rap for the next projects."

"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."

"A+ for being prompt, accurate on time and on the scope of work. I did request to install needed equipment to run the generator and my house had some non-standard situations. I love that all challenges were solved in the right way, not the fast way. The electrician was very open-minded for debating on the possible approaches to an unexpected situations, etc. I love the work, very rational pricing and I would hire again."

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.

Here’s what you can run with different wattages and types of generators:

Portable generator:

  • 2,000 watts can handle a large appliance like a freezer or refrigerator, plus a few smaller items like phones or computer chargers. 

  • 4,000 watts will keep two large appliances operating and a few smaller devices.

  • 8,000 watts should power most essential appliances and other devices, including a sump pump, well pump, or your dishwasher.

Partial to whole-house generator:

  • 20,000 watts and above will make it seem like your home’s power is still on.

An undersized whole-house generator has the potential to overheat and shut down when you try to run a central AC system. This scenario can not only damage the whole-house generator, but can also trip your home’s breakers or cause electrical damage. To avoid this situation, hire a local generator installer to correctly size your whole-house generator.

Setting up utilities on a vacant property usually takes at least a few months, or between 6 weeks to 16 weeks. This process requires working with the local planning and zoning department, hiring a building contractor or engineer to design the utility layout, securing permits, laying the lines, and connecting the utilities.

As a safety measure, you should always turn off the main breaker while operating your generator’s backup breaker. In addition, you should also switch off all appliance breakers so you don't have a power surge when the main breaker turns back on. And finally, turning off the main breaker prevents back-feeding, which endangers utility workers with the risk of electrocution. Back-feeding could also destroy the electrical circuits of your neighbors if they use the same power network.
