Understanding Home Power Needs
Before deciding if a portable generator can power your whole home, it's key to know your household's power needs. The energy needs of a house change based on the number of appliances, heating and cooling systems, and other devices. Start by making a list of the must-have appliances and systems you want to keep running during an outage, like refrigerators, freezers, HVAC, lights, sump pumps, and communication devices.
Calculating Total Wattage Requirements
After listing the essential items, figure out the total wattage needed to power them. This will help you choose the right size generator for your home during a blackout. Experts say a generator with a wattage of 18kW+ is perfect for an average-sized home in Wisconsin, without cutting off any circuits.
For homes with central air conditioning, a 10kW generator is a good choice. Generators under 7kW are portable but might only run a freezer or two briefly, not the whole house. Generators between 7kW to 11kW can power important lights, garage door openers, fridges, freezers, and sump pumps. Those between 11kW to 15kW can also run essential circuits and air conditioning systems.
A 14kW whole-home generator is often enough for powering essential circuits and central air in Southeastern Wisconsin. Generators between 16kW to 24kW work well for average homes as a full backup, and units over 25kW are best for bigger homes with many air conditioning units and high electrical use.
Choosing the right generator size is key for your backup power system's safety, efficiency, reliability, and performance. The right size will also increase your home's value and appeal in Southeastern Wisconsin.
Types of Generators
Choosing the right generator for your home means knowing the different types available. You'll find everything from small, mobile options to big solutions for the whole house. Each type has its own benefits and things to think about.
Portable Generators
Portable generators are small, easy to move, and very useful. They're great for keeping important appliances running during outages. They're also perfect for camping trips or job sites. These generators run on gasoline, making them a budget-friendly choice.
Inverter Generators
Inverter generators are a special kind of portable generator. They make clean, steady power and use less fuel. These are perfect for charging your phone or running small appliances. They're also quiet and good for sensitive electronics.
Standby Generators
Standby generators, or whole-house generators, are set up outside your home. They kick in automatically when the power goes out. These connect right to your home's electrical system, so everything stays powered. They use natural gas or propane, giving you a steady backup power source.

Each type of generator has its own perks and things to consider. From the easy-to-move portables to the full-house standby generators. Knowing what your home needs and what each generator offers will help you pick the best one for backup power.
Can a Portable Generator Power a Whole House
Can a portable generator really power a whole house during a power outage? It depends on the generator's wattage and the home's power needs. The generator's wattage and the home's power requirements are key factors.
Portable generators have a starting wattage that's two to three times their running wattage. This surge wattage is important for starting devices. Homeowners should figure out the total wattage needed for their essential appliances and systems. This will help them decide if a portable generator is enough or if they need a bigger one.
| Appliance/System | Running Wattage | Surge Wattage |
|---|---|---|
| Coffee Maker | 400-800 watts | 800-1,600 watts |
| Microwave | 1,200 watts | 2,400 watts |
| Refrigerator/Freezer | 600-800 watts | 1,200-1,600 watts |

| Electric Furnace | 5,000-25,000 watts | 10,000-50,000 watts |
By knowing the generator capacity and home power needs, homeowners can pick the right portable generators for whole-house power. This ensures their essential devices and systems work during an outage.
"A generator providing between 5,000 and 7,500 watts is generally enough to power a house during an outage."
Sizing Your Portable Generator
Finding the right size for your portable generator is key to keeping your home powered during outages. The wattage of a generator is a major factor. You must add up the wattage of all the important appliances and devices you want to use. This includes their starting (surge) wattages to make sure the generator can handle it.
Wattage Rating
Generators are sized by their electrical output, in watts (W) or kilowatts (kW). A good rule of thumb is to not load a generator more than 90% of its capacity for best performance. Appliances usually need 2-3 times more wattage to start than to run continuously.
Factors to Consider
When picking a portable generator for your home, think about these key points:
- Generator Wattage Capacity: Make sure the generator can handle the total wattage of your essential appliances and devices.
- Fuel Type: Pick a generator that uses fuel you can easily get and find convenient.
- Runtime: Check how long the generator can run to make sure it lasts through outages.
- Portability: Think about the generator's weight and how easy it is to move if you need to.
- Noise Level: Consider how loud the generator is to make sure it meets your noise preferences and local laws.
- Safety Features: Choose generators with strong safety features like automatic shut-off and low-oil protection to protect your home and family.
By looking at these factors, you can pick the perfect portable generator for your home's power needs during outages.
Safety Precautions for Portable Generators
Portable generators are great for backup power, but they must be used safely. It's key to follow portable generator safety steps. This includes the right generator placement and grounding, and fuel storage and handling. These steps help keep you and your property safe.
Proper Location and Grounding
Place your portable generator in an open, well-ventilated spot. Keep it away from windows, doors, and vents. This stops carbon monoxide gas from building up. Use cords rated for the generator's wattage to avoid overloading and fire risks.
Grounding your generator is also vital for safety. Connect it to a grounding rod or system to lower the risk of electric shock or electrocution.
Fuel Handling and Storage
Store fuel for your generator in a well-ventilated area, away from heat and open flames. Don't keep fuel inside or in cars to avoid fire or explosion risks. Always turn off and cool the generator before refueling to prevent ignition.
Regular checks are key for safe use. Look for fuel leaks, replace old parts, and keep oil levels right.
Follow these portable generator safety tips for safe and effective use. This reduces risks of carbon monoxide poisoning, electrical dangers, and fire. Always put safety first with your portable generator.
Limits of Portable Generators
Portable generators are great for power outages but have limits for a whole house. They can handle essential appliances but might not power everything, especially big items like central air conditioners.
Portable generators have a wattage limit. They range from 1,000 to 10,000 watts. This might not be enough for a full house's power needs. Most American homes need a 7,500-10,000 watt generator to run all appliances at once. Central air conditioners need 1,000 to 5,000 watts, and starting can take four times that amount.
