Automatic Backup Power
How Does a Generator Work When the Power Goes Out?
Your System Detects an Outage
The automatic transfer switch monitors your utility power and signals the generator when an outage occurs.
Backup Power Starts
After a brief startup period, the generator powers your selected circuits.
Utility Power Returns
Once utility power stabilizes, your system transfers back and the generator completes its shutdown cycle.
Coverage and runtime depend on system size, connected loads, fuel availability, and operating conditions.
Power Out? No Problem!
What Can a Standby Generator Power During an Outage?
With the right size and setup, a standby generator can keep your whole home running as usual during an outage, powering:
- Heating & Cooling Systems – Stay comfortable year-round.
- Refrigerators & Freezers – Keep food fresh.
- Lights & Outlets – Keep everyday essentials running.

Your Local Generac Team
Automatic Power. Thoughtfully Installed.
Installed outside your home and connected through a transfer switch, a Generac standby generator runs on natural gas or propane. You won’t need to bring a portable unit outside and start it during a storm.
Our team will help you compare capacity, fuel requirements, available monitoring features, and warranty coverage for your selected model.
Home Generator Questions, Answered
Should I choose a standby or portable generator?
A standby generator is permanently installed and starts automatically during an outage. A portable generator generally requires manual setup, startup, and refueling. The best fit depends on the equipment you want to power, your budget, and how much manual operation you prefer.
Can a generator power my whole home?
Some systems can support whole-home coverage, while others serve selected essential circuits. Generator capacity, appliance startup demands, and load management determine what can run together. GSM will review your home’s needs before recommending a system.
How much does home generator installation cost?
Cost depends on generator size, fuel connections, site preparation, electrical work, and permit requirements. Schedule a free installation consultation for a quote specific to your home.
Does a standby generator need maintenance?
Yes. Routine service helps support reliable operation. Follow the maintenance schedule for your model and ask GSM about inspections and service.
