Automatic home standby generators, professionally sized and installed by Delta Power Group — your local licensed Generac dealer in Ohio, Michigan & Texas.
One team, every solution your home needs — Delta also installs GAF roofing and smart-home security, so your generator is handled by a company already trusted inside thousands of homes.
The moment your home loses utility power, the system senses the outage automatically. No flashlights, no fumbling.
Within seconds the unit starts on its own, running on your home's natural gas line or a propane tank. No gas cans, no extension cords.
An automatic transfer switch safely disconnects your home from the grid and moves your circuits onto generator power.
When utility power comes back, the switch returns your home to the grid and the generator shuts itself off and goes back to standby.
Back up everything, or just the circuits that matter most — sizing determines the right fit.
No refueling trips, no gas cans in the garage.
Works whether you're home, asleep, or out of town.
Sump pumps, medical equipment, HVAC, refrigerators, home offices, security systems keep running.
Smart load-shedding can let a smaller unit protect more of your home — ask us.

If you need a new roof, highly recommend talking to Delta Power Group. Not only did they do a great job on my new roof, they also took the time to clean up after themselves.
They really know how to run a business. I've dealt with lots of companies and the majority feel very transactional. Everyone at Delta treats you like family and makes sure you're taken care of. They did my roof and smart home installation almost a year ago and I couldn't be happier with my decision to give them a chance.
