Customers say: True professional

"I had initially gotten a quote for the purchase and installation of my 22KW Generac generator from an electrician. He suggested contacting a Generac dealer to purchase and install my generator. Since I would have to contact a dealer if I had a problem with my generator after installation anyway, it seemed like a good idea. I got a quote from Trinity Generators which was substantially less than my previous quote. Getting the generator from Trinity was an easy choice. They did an outstanding job of installing the generator. Trinity handled all the paperwork and permits all the way to the final inspection of the installation. Trinity sent 4 technicians to install the generator. They started at 9am and finished right after lunch. The installation was fast and neat. They treated the installation as if my home was theirs. They removed all packing material and trash and left my home just as it was before they were there. I couldnâ t be more satisfied and happy with my decision to have them add a generator to my home. 5 Stars!!!!"

"Carlos is a PRO. Came out installed a new 200 amp electrical panel, conduit protected 200 amp line in, full bonding and grounding system, as well as ran a line and installed a generator interlock kit. He was thorough in showing me how to operate everything, the craftsmanship of his work was next level, everything up and running in a timely manner, and the cost was great. 10/10 would recommend for any and all electrical needs."

"Jason installed doorbells at 2 doors. There were no functioning doorbells when I purchased this house 5 years ago. Various contractors warned me of the difficulty and expense of hardwired installations, making me put off the project. Wireless doorbells were unreliable. I was encouraged by James, who did my annual electrical maintenance, and scheduled the work for me. Jason did a fantastic job by creative thinking to avoid the difficulties I'd previously been warned about. He did the job quickly, neatly, and very successfully. I am thrilled to have working doorbells for the first time in 5 years!"

Generator Install questions, answered by experts

While standby generators provide essential backup power, they can fail when you need them most due to lack of maintenance, fuel supply issues, dead batteries, electrical problems, or improper installation. To avoid costly failures, professional installation and regular maintenance are crucial. Licensed technicians ensure safety, uphold warranty requirements, comply with regulations, and provide expert servicing.

If your home already has a grinder pump and you’re still noticing issues (like frequently clogged toilets and sinks), it could be time to upgrade your grinder pump. Start by checking your existing horsepower. If there are four or fewer people living in your home, using a 1/2-horsepower grinder pump should be sufficient. Larger households should consider investing in a 1-horsepower grinder pump to maximize wastewater removal efforts.

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. 

Energy output depends on turbine size, average wind speed at your site, and system efficiency. A 5 kW turbine in a good wind location can generate 8,000 to 12,000 kilowatt-hours per year, which may cover a large portion of an average home’s needs. Accurate output estimates require a professional wind assessment and a review of your household’s energy usage patterns.

You can determine what size generator you need for a transfer switch by matching the switch to the largest outlet on your generator. Larger generators can power up to 10 circuits, while most 5,000-watt generators can provide power to six circuits. So, if your generator’s largest outlet is 30 amps, you’ll need a 30-amp transfer switch.
