How Does a Whole-Home Generator Work?

A whole-home generator continuously monitors incoming utility power. When it detects an outage, the automatic transfer switch disconnects your home from the grid and signals the generator to start.

Once running, the generator supplies selected circuits or home loads, depending on how the system was designed. When utility power returns and stabilizes, the transfer switch shifts your home back to the grid, and the generator shuts down.

Benefits of a Standby Generator

A properly designed system can support many everyday needs during an outage. With a standby generator, Greenville homeowners can expect the following:

• Backup power: Keeps your chosen circuits energized when the grid is down.
• Refrigeration: Protects food and medications from spoilage.
• Lighting: Maintains safe, usable lighting in key rooms.
• HVAC: With a properly sized unit, you can even enjoy continued heating and cooling.
• Home-office equipment: Keeps computers and internet gear available for remote work.

Not every system is able to power all the appliances and pieces of equipment in a typical household. Our advice is to review your priorities with a qualified professional to ensure your system matches your needs.

Whole-Home Generator Installation

Proper setup determines how well your system performs. Corley Pro’s professional home generator installation typically includes these steps:

• Load assessment: Reviews which circuits and appliances need power.
• Fuel selection: Matches the system to available fuel.
• Equipment sizing: Aligns generator capacity with your calculated loads.
• Placement: Positions the unit to meet clearance and code requirements.
• Electrical connection: Connects the generator and transfer switch into your panel.
• Permits: Secures required local approvals and inspections.
• Startup testing: Confirms everything operates correctly before handoff.

Each step of the generator installation process ensures your home and equipment’s safety and performance.

What Size Generator Does Your Home Need?

Sizing should account for your home’s essential loads: the lights, refrigeration, well pump, or medical devices you cannot do without. HVAC equipment — particularly air conditioners and heat pumps — draws the most power, especially during startup. Appliances like ranges and dryers add to the total, so household priorities shape the final list.

Your home’s electrical service matters too, because panel capacity limits the load capability of your whole-home generator. Greenville, SC homeowners are advised to schedule a professional load calculation to address future needs — such as room additions — and prevent undersizing.

Generator Fuel Options

Most whole-home systems run on natural gas or propane. Natural gas offers a continuous supply through your utility line, while propane is stored in an on-site tank, making it a practical choice where gas service is unavailable.

Your decision should be made based on your existing infrastructure, including existing gas lines, meter capacity, and space for a tank. Fuel availability and equipment requirements matter as well, since each generator model is rated for specific fuel types and pressures.

Generator Maintenance

Technicians typically perform oil and filter service, check battery condition, inspect the fuel system, and perform scheduled testing to verify the unit starts and can support the required load. Following manufacturer-specific schedules is essential, as intervals vary by model.

With regular generator service, Greenville homeowners can identify worn parts early. Although maintenance cannot prevent every failure, our Priority Maintenance plan can help identify developing concerns and keep scheduled service on track.

Generator Repair

Certain symptoms indicate the need for immediate attention. Watch for these signs:

• Failure to start
• Unexpected shutdown
• Warning codes
• Abnormal noises
• Fluid leaks
• Reduced output

Early diagnosis may help address a problem before it becomes more disruptive. If you notice any of these, schedule generator repair with a licensed technician as soon as possible.

Preparing for Storm-Season Power Outages

In South Carolina, it isn’t unusual for hurricane season to last until the end of November. Upstate South Carolina can even experience thunderstorms and hurricane remnants late into the season. With simple pre-prep on the backup generator, Greenville, SC residents can keep their system performing optimally:

• Test equipment before expected storm conditions.
• Keep maintenance current.
• Know what loads the system is designed to support.

Remember that while preparation improves storm readiness, there’s no guarantee that your system will provide power in every situation. Nevertheless, taking these precautionary measures will better prepare you for outages.
