Top 5 Best Inverter Generator for Home Backup
10 Best Inverter Generator for Home Backup Review
1. Westinghouse iGen11000TFc Tri-Fuel Portable Inverter Generator
The Westinghouse iGen11000TFc stands as the undisputed champion for large-scale home backup, blending the fuel versatility of a tri-fuel engine with the clean power of an inverter. This unit is designed for homeowners who need to run almost every circuit in their house, including central air conditioning and other large appliances. Its defining feature is the ability to run on gasoline, propane, or natural gas, providing unmatched fuel security during long outages.
Delivering a massive 11,000 peak watts on gasoline, this generator features a 50A outlet and is fully Transfer Switch Ready, ensuring seamless integration into your home’s electrical system. The inverter technology maintains low total harmonic distortion (THD), protecting all your sensitive electronics. However, its significant power comes at the cost of portability; at 191 pounds, it’s quite heavy, requiring careful placement. Nonetheless, the inclusion of a key fob for Remote Start compensates for the weight.
This generator is ideal for those seeking a true whole-house inverter solution and prioritizing fuel flexibility and power capacity above all else. Its combination of output and safety features, like the built-in CO sensor, makes it a top-tier investment for emergency preparedness.

How to Choose Best Inverter Generator for Home Backup
Choosing the right Best Inverter Generator for Home Backup is a balance between power, noise, and fuel security. The primary purpose of an inverter is to convert the raw power generated by the engine into clean, stable AC electricity. This process minimizes the Total Harmonic Distortion (THD), making the power safe for sensitive electronics. This is a crucial distinction from older, noisier conventional generators. To learn more about inverter technology, check out the Wikipedia article.
Wattage Requirements
To correctly size your unit, calculate the running watts of all essential appliances you plan to operate simultaneously, then add the largest starting (surge) wattage to that total. For running essential circuits (refrigerator, lights, furnace fan), 3,000 to 5,000 watts often suffices. However, for large loads like central A/C units or electric water heaters, you’ll need 7,000 to 12,000 peak watts, making accurate calculation essential before purchase.
Noise Level (dBA)
The noise level is a major factor for residential use. Inverter generators typically run between 52 dBA (super quiet) and 76 dBA (louder, high-output). To put this in perspective, 60 dBA is roughly the sound of a normal conversation. When choosing, look for models with ECO Mode or variable throttle, as these features automatically reduce engine speed—and noise—when the power demand is low.
Fuel Versatility (Dual/Tri-Fuel)
Fuel type affects runtime, storage, and availability. Gasoline is common but has a short shelf life. Propane (LPG) is cleaner, easier to store indefinitely, and often cheaper, but offers slightly lower power output. Dual-fuel models provide the essential security of backup fuel, while tri-fuel models (Gas/Propane/Natural Gas) offer the ultimate peace of mind, especially for extended outages where NG lines remain operational.
THD Rating and Clean Power
For a generator to be considered safe for sensitive electronics (smart TVs, phones, computers), it must produce power with low Total Harmonic Distortion (THD). The industry standard for “clean” power is under 5% THD, with the best inverters typically providing under 3%. Always confirm the THD rating if you plan to plug in anything with a microprocessor, as poor power quality can damage internal components.
Connectivity and Parallel Capability
Check the control panel for the right outlets. For home backup via a transfer switch, you’ll need a 30A (L14-30R) or 50A (14-50R) outlet. Parallel capability is a feature that allows you to connect two smaller inverter generators together to double the total power output, providing flexibility to scale your power needs without buying one massive unit.
Advanced Considerations for Best Inverter Generator for Home Backup
When integrating a generator into your home, always plan for safe operation. For long-term outages, consider fuel storage solutions—propane tanks are far easier to manage than bulk gasoline storage. Always use the provided LPG hose and regulator and ensure the generator is operated outdoors, away from windows and doors. Another important element to consider is ATS-Readiness. This feature means the generator has a specific port designed to connect seamlessly with a separately purchased Automatic Transfer Switch, which manages the power switch automatically during an outage, a function usually associated with whole house generators.
How to Use Best Inverter Generator for Home Backup
The key to safe and efficient operation is proper setup and load management.
- Setup/prep: Place the generator at least 20 feet away from the home, ensuring the exhaust is pointed away from all structures. Check the oil and fuel levels and connect the battery if using electric start. Never operate it in a garage or enclosed space due to carbon monoxide risk.
- Core usage & best practices: Start the generator using the electric start, remote fob, or recoil pull. Let it warm up for five minutes before connecting your load. Connect your transfer switch, or plug in items in order from largest to smallest load, ensuring the peak wattage of the largest starting appliance is accommodated.
- Optimization/safety/maintenance: Use the ECO mode when running light loads to save fuel and reduce noise. If your unit has a CO sensor, check that it’s functioning before operation. Regularly check the oil and listen for any unusual noises. Never refuel a hot engine.
- Troubleshooting & pro tips: If the generator trips the circuit breaker, you are attempting to run too many appliances simultaneously—reduce your load. For easy storage, run the engine dry of gasoline or use the fuel shut-off valve to prevent carburetor gumming.
Frequently Asked Questions
What capacity Best Inverter Generator for Home Backup do I need for my house?
For most homes, a unit in the 7,000 to 11,000 peak watt range is sufficient to cover essential circuits and possibly a large appliance like an air conditioner. For strictly minimal needs (lights, fridge, electronics), a 3,000-5,000W model will work. Always consult an electrician to determine the exact wattage required for your home’s setup.
Is an inverter generator truly safe for my laptop and television?
Yes, absolutely. Inverter generators produce power with a very clean sine wave, characterized by low Total Harmonic Distortion (THD), typically under 3%. This is often cleaner than the electricity coming from the utility grid and is completely safe for all sensitive electronics, microprocessors, and smart appliances.
What is the benefit of a Dual-Fuel or Tri-Fuel model?
The main benefit is redundancy and fuel security. Propane (LPG) is easily stored in tanks for years and is widely available, making it an excellent emergency backup when gasoline might be scarce or spoiled. Tri-Fuel adds the option of Natural Gas, which offers unlimited runtime if you have a connected NG line.
Can I use a heavy-duty extension cord to connect my generator to my home?
While possible for small loads, connecting directly to your home’s main panel requires a dedicated high-amperage cord (30A or 50A) plugged into the generator and a Transfer Switch or interlock kit installed by a qualified electrician. This is the only way to safely feed power into your house and avoid back-feeding the utility lines, which can be deadly.
How often should I run my generator for maintenance?
It’s best practice to run your generator for 15 to 20 minutes every month or two, using the fuel you intend to store in it (preferably gasoline with a stabilizer). This keeps the engine lubricated, seals fresh, and helps prevent fuel-related issues. If you choose to run it dry, remember to add fuel before the next scheduled run.
Final Thoughts
Selecting the right inverter generator is the cornerstone of reliable home preparedness. We strongly recommend prioritizing a model that offers a low-THD rating for appliance protection, and that includes a CO safety shutoff for peace of mind. By matching the unit’s peak wattage to your calculated needs and considering the convenience of features like remote start, you ensure a safe and comfortable experience when the lights go out.
For most homeowners needing a high-powered, versatile system, the Westinghouse iGen11000TFc Tri-Fuel offers the Best Inverter Generator for Home Backup due to its unmatched fuel flexibility and enormous output. If you need a more portable, budget-friendly option for essential circuits, the Westinghouse iGen4500 is a leader in low noise and high efficiency.
