Key Takeaways
- Most 1,500 sq ft homes in Augusta need a 12 kW to 16 kW standby generator for full home backup power.
- Generator size depends on total appliance load, not just square footage.
- Central air conditioning and electric water heaters greatly increase the required wattage.
- Standby generators provide automatic, whole-home protection, unlike portable units.
- A licensed electrician should perform a load calculation to ensure safe and proper sizing.
Power outages are common in Augusta, especially during strong storms and hurricane season. When the lights go out, your comfort and safety can be at risk. That is why many homeowners are looking into standby generator installation.
If you own a 1,500 sq ft house, you may be asking, what size generator do I need? The answer depends on how much of your home you want to power and which appliances you need running.
This guide explains how to choose the right generator size for your Augusta home.
How Generator Sizing Works
Generators are sized by watts. Watts measure how much power your appliances and systems use.
There are two important numbers to know:
- Running watts, the power needed to keep something operating
- Starting watts are the extra power needed to turn it on
While square footage gives a starting point, it does not tell the whole story. Your HVAC system, water heater, and major appliances will determine how large your generator needs to be.
Typical Generator Sizes for a 1,500 Sq Ft House
For most 1,500 sq ft homes in Augusta, the right generator size falls between 7.5 kW and 16 kW.
7,500 To 10,000 Watts
This size can power basic needs such as lights, refrigerator, microwave, and a few outlets. It is best for homeowners who only want essential backup power.
12,000 To 16,000 Watts
This range can support central air conditioning, electric water heaters, kitchen appliances, and most home circuits. Many Augusta homeowners choose 14 kW to 16 kW for full coverage.
What Appliances Do You Want To Power?
Before choosing a generator, decide what must stay on during an outage.
Common running watt estimates include:
- Refrigerator, 600 to 800 watts
- Central AC, 3,000 to 5,000 watts
- Electric water heater, 4,000 to 4,500 watts
- Microwave, 1,000 watts
- Lighting, 300 to 1,000 watts
Homes with mostly electric systems will need a larger generator than homes using natural gas for heating and water.
Standby Generator Vs Portable Generator
Portable generators are usually less expensive at the time of purchase. However, they require manual setup each time the power goes out. You must wheel them outside, connect extension cords or a transfer switch, and refuel them regularly. Most portable units have limited wattage and cannot safely run central air conditioning, electric water heaters, and other large appliances at the same time.
Standby generator installation places the unit permanently outside your home. They turn on automatically within seconds of a power outage. These systems connect directly to a transfer switch, which safely powers selected circuits or your entire home. Standby generators typically run on natural gas or propane, providing steady fuel without frequent refueling.
Do You Need A Permit In Augusta?
Yes, standby generator installation in Augusta usually requires permits and inspections. Local codes regulate electrical wiring, transfer switch installation, generator placement, and fuel connections. These rules are in place to protect your home and the public.
Working with an electrician in Augusta, GA ensures all work meets Georgia building and electrical codes. A professional will handle the permitting process and schedule required inspections. This helps avoid fines, delays, or safety risks.
How Much Does A Standby Generator Cost?
The total cost of a standby generator depends on several factors. These include the size of the generator, an electrical panel upgrade, gas line installation, and site preparation work. Larger systems with whole home coverage will cost more than smaller essential load setups.
For a 12 kW to 16 kW system, installation often ranges from several thousand to over ten thousand dollars. While this is a significant investment, it protects your home from costly damage, food loss, and extended discomfort during outages. It can also add value and appeal to your property.
