"I would give Kevin and St. John Electric 10 stars if I could. He put in a fairly challenging outlet for me and also a second outlet for a freezer in the basement and did an excellent job. Very reasonable pricing. I will definitely be calling him in the future for a generator installation. I recommend him highly and without reservations."

"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."

"Andrew came to our house between Ann Arbor and Plymouth at 8 PM on Tuesday when a storm caused an electrical outage. We had a generator but we're only getting partial power in the house. Andrew ran tests inside the house, determining that not enough power was coming into the house. He then started testing different areas of the generator until he found the part not working. Once he located the problem, he quickly fixed it. Because he didn't give up on me or my problem, he restored electricity, saving me hundreds from food spoilage in a refrigerator and freezer. I don't think most electricians would have stuck with the problem or been able or willing to fix the generator. If I could give more than 5 stars, I would."

"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

Costs range from $500 to $2,500, depending on generator type and installation complexity.

A home that is 2,500 square feet will likely need a 20kW to 25kW generator. Consult your local generator installer to confirm the generator size needed to power your home before purchasing a new one. Be sure to consider how much power your necessary devices need to run.

Sizing a generator is a careful process that requires calculating the electrical load of your entire house. You have to take into account every device you want to use and their wattage requirements, plus the wattage needed to start them, and look for a generator that can safely run all that at around 80% capacity.

In more practical terms, a small home can run on a 10,000-watt generator (and if you only want to power a few key appliances, much less than that). A mid-sized home may need something between 15,000 and 22,000 watts. Larger homes require 25,000 watts or more. 

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.

To reduce AC startup power for a whole-house generator, install a soft start kit or hard start capacitor, which lowers the initial surge by gradually ramping up the compressor. Using a smart load manager can also help by staggering startup loads, preventing a system overload and future costly repairs.
