Why Every Murrells Inlet Home Needs a Whole-House Generator

Living in Murrells Inlet comes with a lot of advantages — waterfront access, a tight-knit community, some of the best seafood restaurants on the East Coast, and the kind of outdoor lifestyle that most people have to vacation to experience. It also comes with a reality that every longtime Grand Strand resident understands: when a major storm moves through, the power goes out, and it does not always come back quickly.

Power outages in the coastal Carolinas are not minor inconveniences. They can last for days or even weeks following significant hurricane or tropical storm events. For homeowners without a backup power source, that means no air conditioning in summer heat that routinely pushes into the 90s, no refrigeration for food and medication, no sump pumps running during heavy rainfall, and no lights or communication when you need them most.

A whole-house standby generator changes that equation entirely. When utility power fails, the generator activates automatically — usually within seconds — and your home continues operating normally. This guide covers everything Murrells Inlet homeowners need to know about whole-house generators, from types and sizing to installation, maintenance, and the specific reasons why backup power makes particular sense for properties on the Grand Strand.

The Case for Backup Power in Murrells Inlet

Murrells Inlet is located in Horry County along the central South Carolina coast — precisely the area that Atlantic hurricanes and tropical storms target with regularity. The Grand Strand has seen direct and near-direct impacts from major storms throughout its history, and even storms that make landfall well to the south or north routinely bring extended periods of high winds and heavy rain to the area.

Beyond hurricanes, the Grand Strand sees frequent severe thunderstorm activity throughout spring, summer, and fall. Lightning strikes, downed trees, and wind damage to utility infrastructure cause localized outages that can last hours or days regardless of storm severity. Utility restoration after major events involves prioritizing commercial and critical infrastructure first — residential neighborhoods, particularly in smaller communities like Murrells Inlet, can wait considerably longer.

The other factor that makes Murrells Inlet properties particularly dependent on reliable power is the climate itself. Summer temperatures in the low-to-mid 90s with high humidity make an unair-conditioned home genuinely dangerous for elderly residents, young children, and anyone with certain medical conditions. Losing HVAC during a July or August outage is not just uncomfortable — it can be a health emergency.

For property owners who rent their homes seasonally, power outages have direct financial consequences. Guests who lose power expect either a resolution or a refund, and extended outages during peak rental season can mean significant lost income on top of the disruption itself.

A whole-house standby generator eliminates all of these concerns.

Standby Generators vs. Portable Generators: What Is the Difference?

Homeowners new to the generator conversation sometimes assume that a portable generator — the kind you can buy at a home improvement store and run extension cords from — is a sufficient solution. For temporary, limited use, portable generators can help. But they have significant limitations compared to a permanently installed standby generator.

Portable Generators

Portable generators run on gasoline and must be started manually after an outage occurs. They can only power a limited number of circuits through extension cords or a manual transfer switch, and they must be operated outside due to carbon monoxide risk — which means running extension cords through doorways or windows and going outside in storm conditions to start and refuel them.

Gasoline availability during and after major storms is frequently limited. Gas stations lose power too, and the lines at working stations after a significant storm event can be extremely long. If you do not have fuel stored before the storm, you may not be able to get it when you need it.

Portable generators also cannot power whole-house systems — central air conditioning, well pumps, and electric ranges are typically beyond their capacity, and the manual management of what is running at any given time is a constant task.

Whole-House Standby Generators

A whole-house standby generator is permanently installed outside your home — similar to a central air conditioning unit — and connected to your home’s electrical system through an automatic transfer switch. It runs on natural gas or propane from a permanent supply, which means you never have to worry about having fuel on hand.

When utility power fails, the automatic transfer switch detects the outage and starts the generator within seconds — whether you are home or not. Your home continues operating normally: the air conditioning runs, the refrigerator stays cold, the lights stay on, the security system stays active, and everything functions as it would on a normal day.

When utility power is restored, the transfer switch automatically returns your home to utility power and shuts the generator down. The entire process requires no action from you.

For Murrells Inlet homeowners, particularly those who travel during storm season or own the property as a second home or rental, the automatic operation of a standby generator is not just convenient — it is the only practical backup power solution.

Sizing Your Generator: How Much Power Do You Actually Need?

Generator sizing is one of the most important decisions in the installation process. A generator that is too small will not power everything you need. A generator that is significantly oversized costs more to purchase, install, and fuel than necessary.

Sizing is based on the total electrical load of your home — specifically, what circuits and systems you want the generator to power during an outage.

Essential whole-house coverage — running central air conditioning, the refrigerator, lighting, outlets, and communication systems — requires a generator sized to handle the startup surge of your HVAC system, which is typically the largest single draw in a residential property. For most mid-size Murrells Inlet homes, this puts the requirement in the range of 14-22 kilowatts, but larger homes or those with larger HVAC systems may require more.

Full-load coverage — running everything in the home simultaneously, including electric ranges, clothes dryers, pool pumps, multiple EV chargers, and other high-draw items — requires a larger unit.

The right approach is a professional load calculation performed before any generator is specified. Greg Beverly Services assesses your home’s actual electrical load — not a generic estimate — and recommends a generator sized appropriately for your specific property and the coverage level you want.

Fuel Options: Natural Gas vs. Propane

Whole-house standby generators run on one of two fuel types: natural gas or propane (LP gas). The right choice depends on your property.

Natural Gas

Natural gas is the preferred option for homes with existing natural gas service. The generator connects to the gas line directly and draws fuel as needed — there is no tank to fill, no supply to monitor, and no fuel storage on the property. During extended outages, natural gas supply is typically maintained even when utility power is not, making it the most reliable fuel option for most applications.

Propane

For Murrells Inlet homes without natural gas service, propane is the standard alternative. A propane tank is installed on the property and connected to the generator. Tank sizing matters — a 500-gallon tank provides enough fuel for several days of continuous runtime under normal load conditions, and a 1,000-gallon tank extends that further.

With propane, it is important to keep the tank at a reasonable level during storm season. Running out of fuel during a multi-day outage defeats the purpose of having the generator. Most propane suppliers offer automatic refill programs that maintain a consistent level.

The Generator Installation Process

A whole-house generator installation involves several coordinated steps. Greg Beverly Services handles every aspect of the process.

Site assessment. We evaluate your property to determine the best location for the generator, confirm fuel supply options, and assess your electrical panel to determine what is needed for the transfer switch installation.

Permitting. Generator installations require electrical permits in South Carolina. We handle all permit applications and coordinate the inspection process.

Electrical work. The automatic transfer switch is installed at or near your main electrical panel. This is the component that detects outages and controls the switchover between utility power and generator power. Depending on your panel’s current configuration, some additional electrical work may be needed at this stage.

Generator placement and connection. The generator is installed on a permanent pad — typically poured concrete — outside the home, connected to the fuel supply, and wired to the transfer switch.

Startup and testing. Once all connections are made and the installation is inspected, we perform a complete test of the system, including a simulated power outage, to confirm everything operates correctly.

Orientation. We walk you through the operation of the system, including how to read the control panel, how to manually start or stop the generator if needed, and how to interpret any alerts.

Generator Maintenance: Keeping Your System Ready

A generator that is not properly maintained may fail when it is needed most. Standby generators require periodic maintenance to stay in reliable operating condition.

Weekly self-test. Most modern standby generators perform a short automatic test run once per week — typically a 10-20 minute exercise cycle — to keep the engine lubricated and confirm the system is operational. This happens automatically and does not require any action from you.

Annual service. A licensed technician should perform a full service on your generator annually, including oil and filter change, spark plug inspection, battery check, and a review of all electrical connections and components. Before hurricane season is the ideal time to schedule this service.

Load bank testing. For generators that primarily run short exercise cycles and are not frequently called on during actual outages, periodic load bank testing verifies that the generator can perform under real-world load conditions.

Why Act Before Hurricane Season?

Generator installation is a process that takes time to schedule, permit, and complete. Demand for generator installation increases sharply in the weeks leading up to and following storm events — and the homeowners who waited until they heard a storm was coming are the ones who cannot get a contractor on the schedule.

The smart approach is to plan generator installation during the winter or early spring, well before the June 1 start of hurricane season. This ensures you have time to assess your options without urgency, get the permitting done properly, and have the system installed, tested, and fully operational before the first storm of the season.

If you are reading this before hurricane season, this is the time to act.

Frequently Asked Questions

How long can a whole-house generator run continuously?
A properly maintained standby generator running on natural gas or a sufficiently sized propane tank can run for extended periods — days to weeks — as long as fuel is available. Natural gas supply is rarely interrupted during power outages, making it the most reliable option for extended runtime.

Will a whole-house generator power my central air conditioning?
Yes. One of the primary advantages of a properly sized whole-house standby generator over a portable generator is the ability to run central air conditioning. Sizing the generator correctly to handle the startup surge of your HVAC system is a key part of the installation planning process.

How loud is a standby generator?
Modern standby generators are significantly quieter than older models and most portable generators. Installed at a proper distance from the home and neighboring properties, they operate at a level comparable to a central air conditioning unit. Local setback requirements dictate minimum distances from property lines and structures, and we comply with those requirements on every installation.

Do I need a permit for generator installation in South Carolina?
Yes. Generator installations require electrical permits in South Carolina. Greg Beverly Services handles all permitting as part of the installation process.

What happens to the generator when utility power comes back?
The automatic transfer switch detects the restoration of utility power, returns the home to utility power, and shuts the generator down automatically. You do not need to do anything.

Can a generator power a well pump? Yes. A properly sized whole-house generator can power a well pump, which is an important consideration for Murrells Inlet properties on well water. Make sure well pump load is factored into the generator sizing assessment.

How often should I have my generator serviced?
Annual service is the standard recommendation for whole-house standby generators. The best time to schedule service is in the winter or early spring, before the demands of hurricane season.
