Whole-home Generac and Cummins backup systems, installed the way I'd install one at my own house. Transfer switches, load calculations, permits, and inspections — all handled.
A whole-home standby generator wired to an automatic transfer switch means you don't wait for the power company, and you don't string extension cords through your kitchen. When utility power drops, the generator is running and the house is back on in about 15 seconds — no human involvement required.
I install Generac Guardian and Cummins QuietConnect systems from roughly 14kW through 26kW — appropriately sized for the homes I see most often in Greenville, Seneca, Westminster, and the Lake Keowee communities. I also handle transfer switch replacements, propane/natural gas connections (coordinating with your gas fitter), and pad preparation.
The install is permitted with your county AHJ, load-calculated against your actual panel, and tested end-to-end before I leave. You also get walked through the monthly exercise cycle and what to do if the unit ever throws an alarm.
Not every home needs one. Here's when the math usually works.
Lake Keowee, The Cliffs, Keowee Key, and the surrounding rural roads see longer outages than urban Greenville. Standby power is usually justified.
CPAP, oxygen concentrator, well pump for drinking water, septic lift station, insulin refrigeration — standby becomes more than convenience.
Extended outages during hurricanes, ice storms, or derechos can destroy a freezer's worth of food and knock out your ability to work remotely.
I walk the house with you to identify must-have loads (AC, well pump, fridge, office) and right-size the unit. Oversized costs money you don't need to spend; undersized leaves you in the dark.
Permits pulled with your county AHJ. Concrete pad or composite base sized correctly. I coordinate with your propane supplier or gas fitter for the fuel line. HOA paperwork handled on request.
Transfer switch wired between utility and panel, generator commissioned, full outage test performed. You get a walk-through of operation, monthly exercise, and what to do if it alarms.
A standby generator is an eight-to-fifteen year piece of equipment. The install matters more than the brand.

Most installs land between $9,000 and $18,000 depending on size (14kW–26kW), transfer switch scope, pad work, and fuel line run. I give a fixed written quote before starting — no squishy ranges.
Both are solid. Generac has broader local dealer/service coverage in Upstate SC. Cummins units tend to run quieter at the same kW rating. I'll give you a straight opinion for your specific situation.
I don't do fuel-line work — that's gas fitter territory. But I coordinate the schedule with your propane supplier or plumber so your install lands in one coordinated effort, not three separate stressors.
Yes. All permits pulled with the county AHJ in your name. You get the signed inspection paperwork at closeout.
Most installs wrap in 1–2 days of actual electrical work once permits, pad, and gas are coordinated. The whole project cycle (site visit → unit delivered → installed → inspected) typically runs 3–6 weeks depending on equipment stock.
I install, test, and handle electrical troubleshooting. Annual service (oil, filters, firmware) is best left to a factory-authorized service tech. Happy to recommend one.
Let's walk your panel, size it right, and get a written quote on your desk this week.
