Stop sitting in the dark, Ann Arbor! Power outages happen across Washtenaw County due to summer storms, winter ice, or grid overloads. A standby generator provides an automated solution that runs your essential appliances while you wait for DTE Energy or another provider to restore electricity.
What does “standby generator” mean and how does it help protect my home?
A standby generator is a permanently installed power system that automatically restores electricity to your home during power outages. These devices connect to your electrical panel and your home’s natural gas or liquid propane fuel line. The generator monitors utility voltage 24/7 to help protect essential appliances, heating and cooling equipment, and sensitive electronics.
When evaluating backup power options, understanding the components of a standby system highlights why it’s superior to portable generators:
- Permanent Outdoor Enclosure: Unlike portable generators that must be wheeled out of storage and run outdoors in the rain or snow, a standby generator sits permanently on a concrete or composite pad outside your home. Wrapped in an all-weather, sound-dampened housing, it’s ready to operate instantly.
- The Automatic Transfer Switch (ATS): This constantly monitors your incoming utility power. The moment grid drops, the ATS safely disconnects your home from the main utility line and starts the generator to start. This restores your household power within 10 to 20 seconds, even if you are away from home or asleep.
- Continuous Fuel Supply: You don’t need to fill a standby generator with gasoline during outages and storms. The unit connects to your natural gas line or liquid propane tank so it can run until grid power comes back.
- Whole-Home or Essential Circuit Coverage: You can customize your backup power load based on your needs and budget. Essential-circuit systems power critical equipment such as your furnace, sump pump, refrigerator, and medical devices. A whole-house generator can run your entire electrical panel, including central air conditioning and appliances.

Once I Get a Standby Generator, Is There Anything I Have to Do?
After your generator is professionally installed, your main responsibility is making sure the unit gets routine maintenance so you can rely on it during emergencies. Scheduling annual inspections with a certified technician helps keep fuel lines, electrical connections, and engine components operational before severe weather strikes.
Here’s some of what a licensed electrician does when handling your generator’s ongoing maintenance:
Schedule Annual Inspections
Even if your generator hasn’t been used in the past year, maintenance is essential to keep it ready and fully operational. A certified technician inspects electrical connections, verifies the automatic transfer switch is working, and tests battery voltage. They also check fuel supply pressures to make sure your system starts properly when needed.
Regular Oil and Filter Changes:
Just like your car, a standby generator needs clean engine oil and fresh filters to protect its mechanical components from wear and overheating. Engine oil should be replaced every 100 to 200 operating hours during a prolonged outage, or at minimum once per year. Fresh lubrication prevents sludge buildup, maintains oil pressure, and helps extend the operational lifespan of your generator.
Battery Health and Charge Levels:
Your generator’s electric starter motor relies on an internal 12-volt battery to crank the engine when utility power fails. Over time, those freezing winter nights in Ann Arbor can weaken the unit’s battery capacity and its ability to hold a charge. Routine maintenance includes testing battery cold-cranking amps, cleaning terminal corrosion, and replacing aging batteries every two to three years.
Enclosure Clearance and Vent Cleaning
You should regularly clear away fallen leaves, snow, and lawn debris so it doesn’t block your generator’s intake and exhaust vents. Airflow is vital for engine cooling and carbon monoxide safety, and proper ground clearance keeps moisture from damaging electrical components. Keeping a clear, three-foot perimeter around your generator helps with safe operation and gives service technicians easy access during maintenance visits.
Pro Tip: Neglecting these yearly checkups can lead to hidden component degradation that leaves your home vulnerable during the next blackout.
