In a house that is reliant to electricity, a power outage is one of the last things you want. It’s dark, you cannot charge your phone, and the food in your fridge is going bad.
That’s why you need a generator for home backup, or an inverter generator specifically. It will transform high frequency AC current to DC current and back to AC current, hence the name.
Inverter generator is better because its complex engine creates less sound than a regular generator. Most importantly, it can supply energy at a steadier rate.
In this post, I have compiled the 10 best inverter generators for home backup. I will discuss each of their pros and cons to help you find your perfect inverter generator.

10 Best Inverter Generators for Home Backup in 2021 – My Reviews
1. WEN 56380i Super Quiet Inverter Generator
One of the most popular inverter generators on the market is the WEN 56380i. It is available in 4 different wattages (3800W, 4000W, 6250W, 8750W) to supply steady electricity into your home.
It’s equipped with a fuel shutoff that will use up the remaining fuel in the carburetor before shutting down. This will prevent blockages and limit maintenance, while increasing its lifespan.
The WEN 56380i is also popular for its capability to produce clean power with less than 1.2 percent total harmonic distortion. It also has a compact design and doesn’t need regular maintenance, yet it is recommended to change the oil every 25 hours.
Some people find this inconvenient s. Another minor complaint about this generator is its wheel that is almost dysfunctional, although the generator is lightweight and still portable.
- Long lifespan

- Requires regular oil change
- Dysfunctional wheel
2. Honda EU2200i Portable Inverter Generator
If your house uses up less power, I recommend getting a cheaper and smaller generator. The Honda EU22001 is a portable inverter generator with a wattage of only 2200W.
This generator has an exclusive eco-throttle system, works efficiently and can run for 4 to 9.6 hours on a single tank. Most importantly, its powerful engine is extremely quiet and will not disturb your neighbor.
If 2200W is not enough, you can add a second additional unit for extra power. This will increase the total wattage to 4400W which is suitable even for time-consuming applications. However, it does require you to make an additional purchase.
Users make almost no complaints except for this low wattage, and that is why this generator deserves a spot amongst the other best inverter generators for home backup.
- Exclusive eco-throttle system to preserve energy
- Quiet engine
- Low wattage (2200W)
3. Briggs & Stratton P4500 Inverter Generator
Briggs & Stratton P4500 is a classic inverter generator that is reliable for home use, and available in 5 different wattages from 2200W to 6500W. It has a 4-stroke engine that will supply steady power into your home.
The standout feature of this generator is their unique COGUARD carbon monoxide shutdown technology, which will automatically shut the generator down when harmful levels of carbon monoxide are detected.
The generator does come with a user-friendly display and guide to help you start the generator. However, it does take a relatively longer time to turn on.
The protective shell contributes in minimizing sound, but this generator is definitely not the quietest inverter generator available.
- Safe COGUARD technology to detect carbon monoxide
- Supply steady power
- User-friendly display
- Takes longer time to start
- Quite loud
4. Yamaha EF2000iSv2 Inverter Generator
Do not bother getting a large generator if your house does not require much power, in which case the Yamaha EF2000iSv2 may be the perfect choice for you. This generator is only 1600W with a maximum output of 2000W.
The small engine also means that it creates less sound, while the smart throttle system ensures that it will adjust their output to maximize efficiency.
The Yamaha EF2000iSv2 is also equipped with an oil watch warning system that will prevent engine damage caused by low oil. It’s an ingenious feature as it will save you maintenance and repair cost.
The design is small and compact, yet it does not have a user display and may be confusing for some people.

How to choose an inverter generator for home backup
Here are several things to consider before deciding on an inverter generator for home backup.
Wattage is the amount of power the generator can supply when it’s full. The higher the wattage, the more expensive the generator will cost.
Around 4000W should be enough for most houses, but if you opt for the cheaper 2000W, make sure to use the power efficiently.
2. Noise Level
The last thing you want is for your neighbor to complain about your noisy generator. Generators with less wattage usually make less noise, although most inverter generators aren’t loud enough to disturb both you and your neighbor.
If space is a concern, please consider the size of the generator. Smaller generators weigh less and require less space. So, remember to make sure that your generator fits your house well.
4. Automatic Start
For maximum convenience, try getting a generator with automatic start. When the power goes off, it will conveniently turn itself on without you having to lift a finger. Of course, this is not a crucial factor and there are cheaper alternatives.
5. Low-Oil Shutoff
This feature enables your generator to automatically shut off when it is low on oil. This is a standard feature that will help prevent your generator from being broken. Generators with this feature usually have more lifespan and require less maintenance.
Most brands provide warranty, but you should check before purchasing. There’s always a possibility of your generator not functioning well for various reasons. So, warranty becomes a safety measure, but let’s just hope you will not have to claim it.
7. Customer Reviews
Make sure to refer to our list of best inverter generators for home backup. If you still cannot decide, just pick your top contenders and look at their customer reviews.
People like different generators for different reasons, so checking customer reviews will help you decide which one is best for you.
Make sure to set a budget because inverter generators are not cheap. If your budget is tight, we recommend getting a lower wattage generator.
Just make sure to use the power wisely and it should be enough to last you through a blackout. However, we definitely recommend getting a more advanced generator if you have enough on your budget.
This concludes my list of the 10 best inverter generators for home backup and how to choose the perfect generator. The next step is simple, simply think about these 8 factors and buy one generator from the list above.
Whichever generator you decide to buy, I guarantee that it would work well as your home backup. Good luck!
