What Size Generator Do You Need? Hurricane Prep Tips for South Carolina Homeowners

How to Choose the Right Size Generator for Your Home’s Storm Backup Needs in SC

When storm season arrives in South Carolina, having reliable backup power isn’t optional—it’s essential. Between hurricanes, tropical storms, and widespread outages, a properly sized generator can keep your home safe, comfortable, and functioning when the power goes out.


At Ashley River Wired, we help homeowners across South Carolina select and install generators tailored to their specific needs. Here’s how to choose the right size generator for your home—and why expert installation makes a difference.


Why Generator Sizing Matters

Not all generators are created equal, and selecting the wrong size can lead to serious problems. A generator that’s too small may fail to power essential systems, while an oversized one wastes fuel and money and may not operate efficiently.


Proper home generator sizing ensures your backup power system runs efficiently and reliably when you need it most. This is especially critical in South Carolina, where backup generators for hurricanes help homeowners prepare for unpredictable weather patterns.

Understanding Your Home’s Power Needs

To choose the right generator, start by evaluating your home’s power requirements during an outage. Make a list of essentials you’ll want to keep running, such as:

  • Refrigerators and freezers
  • Heating and cooling systems
  • Well pumps and sump pumps
  • Lighting and security systems
  • Medical devices
  • Internet routers and electronics

Adding up the wattage for each device gives you a starting point for determining your whole house generator requirements. Depending on your household size and power usage, generators typically range from 7,500 to 20,000 watts or more.


If this process feels overwhelming, AR Wired can help by performing a comprehensive load assessment to recommend the ideal size generator for your South Carolina home.


Types of Generators to Consider

With your power needs in mind, the next step is choosing between portable and standby generators:

  • Portable Generators: Affordable and flexible but require manual setup and refueling. They’re ideal for short-term, minimal power needs.
  • Standby Generators: Permanently installed and connected to your home’s electrical system. These units activate automatically when the power fails, providing uninterrupted power—crucial during South Carolina’s hurricane season.

For most South Carolina homeowners, a standby generator is the best generator for power outages due to the risk of extended outages following hurricanes or tropical storms.

At Ashley River Wired, we specialize in generator services that ensures your system is seamlessly integrated with your home’s electrical infrastructure.


How Professionals Determine the Right Generator Size

A generator’s capacity isn’t just about adding up appliances. Professionals consider factors like starting vs. running wattage, surge demands, and potential future power needs.

Our licensed electricians at AR Wired provide comprehensive South Carolina generator installation services, including:

Bonus Protection: Surge Protection & System Integration

South Carolina storms often cause power surges that can damage electronics and your generator. That’s why we recommend pairing your generator with a surge protection system to shield your home’s devices and backup power source.


During generator installation, AR Wired can also integrate these protections, ensuring your entire system is prepared for hurricane season.

Common Electrical Issues Homeowners Should Never Ignore

By Ashley River Wired • June 30, 2026
Some electrical problems do not announce themselves loudly at first. They show up as a lamp that flickers during dinner, an outlet that feels slightly warm, a breaker that trips while the laundry is running, or a porch light that stops working after a storm. At first, it may seem like an inconvenience. Over time, that small symptom can become a warning sign. For Charleston homeowners, electrical problems can be shaped by older wiring, coastal humidity, storm exposure, and the growing number of devices used every day. Ashley River Wired helps homeowners look past the surface issue and find what is actually happening behind the switch, outlet, panel, or fixture. If something in your home feels unsafe, unreliable, or keeps coming back after a reset, it may be time to call an electrician for electrical issues before the problem becomes more expensive. The Outlet That Feels “Almost Normal” Picture this: one outlet in the living room still works, but the plug does not sit firmly anymore. A lamp flickers when someone walks by. Later, the outlet feels warm after a phone charger has been plugged in for a while. Before the repair, the homeowner may think the outlet is simply old. After inspection, the issue may turn out to be a loose connection, worn device, or wiring problem that should not be left alone. Warm outlets, loose plugs, discoloration, or small crackling sounds should always be taken seriously. Ashley River Wired can inspect the outlet and determine whether the problem is limited to that device or connected to a larger circuit concern.

Your panel controls how power moves through the property. When it can no longer support daily electrical demand, the signs may show up through tripping breakers, flickering lights, warm components, or limited power for modern appliances. In Charleston homes, panel concerns can be more common in older properties, renovated homes, and houses adding new electrical features. Ashley River Wired helps homeowners understand when a panel should be inspected, what warning signs matter, and when an upgrade may prevent bigger electrical problems. Indoor Signs Your Electrical Panel May Be Struggling Many panel problems first appear inside the home. A breaker that trips once may not mean the panel needs replacement, but repeated issues should not be ignored. If lights dim when appliances run, outlets feel warm, or certain rooms lose power often, the system may be under stress. A certified electrician can check whether the problem is caused by the panel, a circuit, wiring, or connected equipment. Ashley River Wired looks at how the home is actually using power, not just whether the panel is still turning lights on. Common indoor warning signs include: Breakers that trip repeatedly Flickering or dimming lights Warm outlets, switches, or panel areas Buzzing sounds near electrical components Not enough circuits for modern appliances These symptoms may point to overload, aging equipment, loose connections, or a panel that no longer fits the home’s needs.
