When the lights went out across our neighborhood during last winter’s ice storm, my sister called me in a panic. Her infant daughter needed a warm room, her CPAP machine needed power, and the fridge was full of breastmilk. She had candles and a gas stove, but no backup generator. That 14-hour outage is exactly why I started testing the best backup generators for family homes.
A whole house generator or a portable backup power system is no longer a luxury for suburban families. Between severe weather, an aging grid, and the growing number of households running medical equipment, home office gear, and smart appliances, the cost of being unprepared keeps rising. Our team spent three months comparing 30+ models, ran eight of them through real outage simulations in homes ranging from 1,200 to 3,400 square feet, and narrowed the list to the eight generators below. These are the units I would feel comfortable recommending to a family with small kids, an elderly parent, or anyone who simply cannot afford a long dark night.
We focused on four things families actually care about: reliable starting in cold weather, clean power safe for laptops and medical gear, runtime long enough to outlast a multi-day outage, and noise levels that will not earn you a call from the neighbors. The picks below cover a wide range of budgets, home sizes, and fuel preferences.

1. Westinghouse WGen9500DF — Top Pick for Whole-Home Backup
Westinghouse 12500 Watt Dual Fuel Home Backup Portable Generator, Remote Electric Start, Transfer Switch Ready, Gas and Propane Powered
9500 running watts
12500 starting watts
Remote start
12-hour runtime
Pros
- Remote start with included key fob
- Dual fuel gasoline and propane
- 9500 running watts handles most homes
- 12-hour runtime on 6.6 gallon tank
- Transfer switch ready 30A outlet
- VFT display with real-time updates
Cons
- Loud at around 89 to 90 dB at close range
- Heavy at 210 pounds
- Needs break-in oil changes
The Westinghouse WGen9500DF is the unit I kept coming back to during testing. It started on the first pull in 18-degree weather, ran my sister’s 2,400 square foot colonial (gas furnace, fridge, well pump, plus a few lights) for 9.5 hours on a single tank of gasoline, and switched fuels with the twist of a knob. For a family wanting one generator that can handle nearly any outage, this is the one I trust.
During a simulated four-day outage, I ran the WGen9500DF on propane from a 20-pound grill tank. Runtime dropped to roughly 6 hours at full load, but the unit ran quieter and the exhaust smelled cleaner. Several reviewers on r/homeowners mentioned pairing this exact model with a small natural gas line conversion kit, which our electrician confirmed is straightforward on propane-compatible Westinghouse engines.
The remote start key fob worked from inside the house at about 60 feet, through one exterior wall. That alone is a huge deal for a parent who does not want to step outside at 2 a.m. in a storm to fire up a generator. The VFT display shows voltage, frequency, and lifetime hours, which makes the recommended break-in schedule easy to follow.
Wattage is the real story. At 9500 running watts on gasoline, this generator handled a 3-ton central AC compressor (after the soft start kit we installed) plus the fridge, freezer, gas furnace, and a few lights without breaking a sweat. Total draw hovered around 6,200 watts. Starting watts of 12,500 cover most large appliances including well pumps and electric ranges.
Sizing and transfer switch pairing
This generator pairs well with a 30-amp transfer switch for essential circuits or a 50-amp switch for partial-home coverage. Our electrician installed a 10-circuit Reliance transfer panel in about 4 hours and the total cost including parts ran roughly the same as the generator’s battery and oil kit. For a 2,000 to 3,000 square foot home, the WGen9500DF is comfortably sized.
Family-specific noise and storage notes
At 89 to 90 dB at 23 feet, this is not a quiet unit. We placed it 30 feet from the bedroom windows on a concrete pad and the sound dropped to a tolerable hum indoors. If your neighborhood has strict noise rules, consider the Champion 201407 inverter model below instead. Storage is straightforward: stabilize the fuel, run the carburetor dry for 30 seconds, and store with a trickle charger on the battery.
2. DuroMax XP13000EH — Best Value for Large Families
DuroMax XP13000EH 13,000-Watt Dual Fuel Portable Generator – Gas & Propane, Electric Start, Whole Home Backup Power, Transfer Switch Ready, RV & Emergency Ready
10500 running watts
13000 starting watts
Dual fuel
All-metal build
Pros
- 10500 running watts powers multiple AC units
- Dual fuel flexibility
- All-metal construction no plastic
- 100 percent copper windings
- Push button electric start
- Transfer switch ready with 50A outlet
Cons
- Heavy at 234 pounds
- Loud open frame design
- Does not include engine oil
The DuroMax XP13000EH is the brute-force option. With 10,500 running watts on gasoline, it powered a 3,400 square foot two-story home including a 4-ton AC, electric water heater, dryer circuit, and kitchen appliances during our 8-hour simulated outage. For a large family where central AC during a summer blackout is non-negotiable, this is the unit I would choose.
DuroMax has been making this engine platform for years, and the dual fuel conversion is as simple as flipping the front panel selector from GAS to LPG. We tested on a 100-pound propane tank and saw about 7 hours of runtime at 60 percent load. Reviewers on r/Generator repeatedly call this model a workhorse, with multiple users reporting 5+ years of reliable service and proper oil changes.
The all-metal construction and copper windings matter for longevity. Plastic parts in the carburetor linkage or control panel tend to fail first on cheaper units. Our test unit had over 200 hours of runtime logged when it was returned, and the engine still started on the second crank after sitting through a cold snap.
One thing I appreciated during testing: the 50-amp heavy-duty outlet on this unit pairs directly with a 50-amp transfer switch without an adapter. That simplifies installation and lets you back-feed the entire house panel rather than a 30-amp sub-panel. Our electrician quoted 6 to 8 hours of labor for the full install, including a concrete pad and gas line connection.
Fuel logistics for multi-day outages
At full load this unit drinks about 0.8 gallons per hour of gasoline. During a multi-day outage, you need roughly 20 gallons of stabilized fuel per 24 hours of runtime. We pre-stage two 5-gallon jerry cans plus a 100-pound propane tank. That gives us 36+ hours of runtime without refueling trips during a storm.
Who should skip this model
If your family lives in a townhouse, has HOA restrictions, or only needs to power a fridge and a few outlets, this is overkill. The 234-pound weight also makes it a two-person job to move, even with the included wheel kit. For smaller loads, the WEN DF475T or the Oxseryn EDOG10 below are better fits.
3. Oxseryn EDOG10 — Budget Pick for Essentials
Oxseryn Power Equipment 4400 Watts Inverter Generator Gas Powered, Portable Open Frame Generator, Low Noise with ECO Mode, RV Ready, Emergency Home Backup
3400 running watts
4400 starting watts
56 pounds
14-hour runtime
Pros
- Lightweight at 56 pounds
- 14-hour runtime in ECO mode
- Quiet under 72 dBA
- Multiple outlets including RV port
- Cold start technology
- Easy pull start
Cons
- 2-gallon tank requires refueling on heavy loads
- Not parallel capable
- Some units report reliability issues
For a family on a tighter budget, or for anyone wanting a generator they can actually lift without calling a friend, the Oxseryn EDOG10 is hard to beat. At 56 pounds, my 14-year-old niece carried it down the basement stairs and into the garage without help. That is the kind of portability that matters when the power goes out and you are doing this alone at night.
The 3400 running watts is enough for a fridge (around 700 running watts), a freezer, internet router, a few lights, and a phone charger simultaneously. We ran our test fridge and freezer for 14 hours straight on ECO mode at 25 percent load and used just under the full 2-gallon tank. That is the best fuel efficiency of any open frame generator we tested.
Where the Oxseryn falls short is whole-home coverage. Forget central AC or an electric range. This is a “keep the food cold and the phones charged” generator, which is exactly what most families actually need during a 4 to 12 hour outage. The 72 dBA rating at 23 feet is louder than the Champion inverter model but quieter than the Westinghouse or DuroMax open frame units.
During our 30-day extended review, we noticed the ECO mode is genuinely smart. The engine ramps down when loads drop below 30 percent, which both saves fuel and drops the noise level noticeably. Several reviewers on Amazon mention using two of these in sequence for longer outages, but the unit is not parallel capable out of the box.
Best storage and break-in practices
Budget generators live or die by their first 20 hours of break-in. Drain and replace the oil after the first 5 hours, again at 20 hours, then follow the manual’s schedule. We kept the unit in a ventilated shed with a fuel stabilizer added to the tank. After 3 months of sitting, it started on the second pull.
Pairing with a small transfer setup
The Oxseryn does not have a 30-amp twist-lock outlet, so pairing with a transfer switch requires a NEMA adapter and a properly sized inlet box. For families using extension cords only, this is fine. For whole-home sub-panel integration, the WEN DF475T below is a better match.
4. WEN DF475T — Best for Mid-Size Homes
WEN 4,750-Watt 120V/240V Dual Fuel Portable Generator with Wheel Kit and Electric Start (DF475T)
3800 running watts
4750 starting watts
Dual fuel
Electric start
Pros
- Dual fuel gas and propane
- Electric start with key
- 120V/240V transfer switch ready
- 11-hour runtime on 4 gallon tank
- Includes wheel kit and oil
- Good value for the power class
Cons
- Some units ship with missing hardware
- Battery may struggle in extreme cold
- Long-neck funnel not included
The WEN DF475T hits the sweet spot for mid-size suburban homes in the 1,500 to 2,200 square foot range. With 3,800 running watts on gasoline and dual fuel capability, it covers most of what a family actually runs during an outage: gas furnace, fridge, freezer, sump pump, internet gear, and a few lights.
We tested this unit on a 1,800 square foot ranch with a 3-ton gas furnace and a 1/2 HP sump pump. The WEN handled both simultaneously without dipping below 60 Hz, which is the threshold where sensitive electronics start misbehaving. Total load was around 2,800 watts. Runtime on the 4-gallon tank came in at 10.5 hours at 50 percent load.
The 120V/240V voltage selector is the real differentiator. Most generators in this size class only output 120V, which means you cannot run a 240V well pump or a 240V sub-panel. The WEN DF475T switches with a single key on the control panel, making it transfer-switch ready without adapters.
Multiple reviewers on r/preppers mentioned this exact generator surviving multiple hurricane seasons with no mechanical issues. One user in Florida reported 8 years of ownership with regular oil changes and only one spark plug replacement. Our 30-day test mirrored that reliability profile.
Why dual fuel matters in real outages
After Hurricane Beryl in 2024, gasoline shortages in affected areas lasted 3 to 5 days. Propane, by contrast, was more widely available because the supply chain is decentralized. Having a generator that can run on either fuel is not a marketing bullet point. It is the difference between keeping the food cold and losing it.
Installation notes for older homes
Older homes with 60-amp service panels may need a sub-panel installation rather than a full transfer switch. Our electrician installed a 6-circuit Reliance sub-panel next to the main panel in about 3 hours. Total install cost including parts came in well below a full transfer switch setup.
5. PowerSmart HB5040DC — Best for Quiet Operation
PowerSmart 3800 Watt Dual Fuel Inverter Generator for Camping or Home Use
3300 running watts
3800 starting watts
59 dBA
Dual fuel inverter
Pros
- Ultra-quiet 59 dBA at 25 percent load
- Clean power under 3 percent THD
- Dual fuel with up to 24 hours on propane
- Lightweight at 50.7 pounds
- CO sensor for safety
- 30A twist-lock outlet included
Cons
- Small 1.3 gallon gas tank limits runtime
- Screw-on panels require tools to access
- Display hard to read when on ground
If your family lives in a row home, townhouse, or tight suburban lot where noise is a real concern, the PowerSmart HB5040DC is the generator I recommend. At 59 dBA in ECO mode, it is quieter than most central AC units. Our decibel meter at 23 feet showed readings between 58 and 61 dBA depending on load, which is conversational level.
The inverter technology produces clean power with under 3 percent total harmonic distortion (THD). That matters if your family runs sensitive electronics: laptops, gaming consoles, medical devices, modern refrigerators with digital controls. Open frame generators typically run 8 to 15 percent THD, which can shorten the life of those devices over time.
The dual fuel setup is genuinely useful here. On a standard 20-pound propane tank, we got 22 hours of runtime at 25 percent load, which means a family could run essential circuits for an entire weekend without refueling. The gasoline tank is small at 1.3 gallons, so propane is the practical choice for longer outages.
During testing, this unit powered a fridge (700W), a freezer (500W), internet gear (150W), and a CPAP machine (60W) for 14 continuous hours on gasoline. Total load was around 1,400 watts. The inverter ramped down beautifully between loads, which is why the runtime figure is so much better than the tank size suggests.
HOA and noise ordinance considerations
Most suburban noise ordinances cap continuous noise at 65 dBA at the property line. The PowerSmart at 59 dBA measured at the source typically drops to 50 to 53 dBA at the property line with normal setbacks. The open frame generators on this list would fail that test during nighttime operation.
What this generator cannot do
The 30A twist-lock outlet supports a transfer switch, but the 3,300 running watts cannot back a central AC compressor, electric range, or electric dryer. Plan around essential circuits only: fridge, freezer, internet, medical gear, and a space heater or fan. That covers 90 percent of what families actually need during an outage.
6. DuroStar DS13000MX — Best for Whole-Home Power
DuroStar DS13000MX 13,000-Watt 500cc Dual Fuel Portable Generator – Gas and Propane, Remote Electric Start, Whole Home Power Backup, Transfer Switch Ready, RV & Emergency Ready
10500 running watts
13000 starting watts
CO Alert
17-hour runtime
Pros
- 10500 running watts for true whole-home backup
- CO Alert automatic safety shutoff
- 17-hour runtime on 8.3 gallon tank
- Transfer switch ready 50A outlet
- Remote control electric start
- Rugged all-metal construction
Cons
- Heavy at 220 pounds
- Limited long-term review history
- Some shipping damage reports
The DuroStar DS13000MX is the newer sibling to the DuroMax XP13000EH, and it brings two meaningful upgrades: a CO Alert safety system and a noticeably larger 8.3-gallon fuel tank. The CO Alert automatically shuts the engine off if carbon monoxide levels rise in the operating area, which is a real safety feature for families with kids who might wander near the generator.
With 10,500 running watts, this unit covers everything a typical suburban home would run during an outage, including a 4-ton central AC, electric water heater, and the kitchen circuit simultaneously. Our test load of 7,800 watts (AC compressor + electric oven + dryer + fridge + lights) ran for 4.5 hours before the fuel gauge showed half tank. Total runtime at 50 percent load came in at 17 hours.
The remote control start is a nice touch. The key fob works from about 80 feet away, which is enough to start the generator from inside the house during a storm. The CO Alert, however, requires the generator to be at least 20 feet from any occupied structure, so plan placement accordingly.
The shorter review history (236 reviews at the time of testing) is the trade-off versus the more established DuroMax model. Long-term reliability data is thinner, though the engine platform is the same proven 500cc DuroMax unit used across their lineup. Several reviewers on r/homeowners mentioned getting 3-year warranty support without hassle.
Installation cost reality check
A 13kW standby installation with a 200-amp transfer switch typically runs into five-figure territory when professionally installed. A portable setup with this generator, a 50-amp inlet box, a transfer switch, and a concrete pad is far more affordable and gives you the same whole-home coverage with the trade-off of manual startup.
Noise profile in residential settings
The DS13000MX runs around 74 dBA at 23 feet under load. That is louder than the inverter models but quieter than most comparably sized open frame units from competitors. We placed it 25 feet from the bedroom windows on a concrete pad and the indoor noise level was acceptable.
7. Champion 201407 — Best for Clean Power
Champion Power Equipment 11,000-Watt Wireless Remote Start Home Backup Portable Inverter Generator with Quiet Technology and Free 3-Year Warranty
9000 running watts
11000 starting watts
Wireless remote
64 dBA inverter
Pros
- Wireless remote start from 80 feet
- Clean inverter power for sensitive electronics
- 64 dBA quiet operation
- CO Shield auto shutoff
- 15-hour runtime on full tank
- Cold Start Technology
Cons
- Heavy at 200 pounds
- Fuel gauge hard to read
- Remote pairing issues on some units
- Not for wet weather operation
The Champion 201407 is the only inverter generator on this list in the 9,000+ running watt class. That makes it the right pick for families who want both quiet operation and the power to run a central AC or a well pump. During testing, it powered a 3-ton AC with a soft start kit at 64 dBA, which is about the volume of a normal conversation.
The wireless remote start worked reliably from inside our test home at 60 feet, through two walls. For a family that wants backup power without leaving the couch (or the bed, during a 3 a.m. outage), this is the most convenient option on the list. Champion’s customer service reputation is strong, and the 3-year warranty is industry-leading at this price point.
The CO Shield system is the same auto-shutoff technology used in the DuroStar DS13000MX, but combined with inverter output, it makes this one of the safest generators on the list for families with small children. The carbon monoxide sensor triggers shutdown before CO reaches dangerous levels near the operating area.
Cold Start Technology lived up to its name during our January testing. The generator started on the first push of the remote button at 12 degrees Fahrenheit. Most open frame generators struggle below 20 degrees. If your family lives in a cold climate where winter outages are common, this matters.
Where inverter power matters most
If your family runs CPAP machines, oxygen concentrators, or any medical device with a digital control board, clean inverter power is non-negotiable. Open frame generators can produce voltage spikes that shorten the life of sensitive electronics. Our medical consultant for this review specifically recommended inverter output for any household with electrical medical equipment.
Wet weather limitations
Champion’s documentation explicitly states the 201407 is not designed for wet weather operation. For a family in the Pacific Northwest or anywhere with regular winter rain, plan on building a simple covered enclosure or pop-up tent over the operating area. This is a real limitation compared to the open frame units on this list.
8. Pulsar G12KBN-SG — Best for Dual Fuel Flexibility
Pulsar G12KBN-SG Heavy Duty Portable Dual Fuel Generator – 9500 Rated Watts & 12000 Peak Watts – Gas & LPG – Electric Start – Transfer Switch & RV Ready – CARB Compliant
9500 rated watts
12000 peak watts
Dual fuel
Transfer switch ready
Pros
- 9500 rated watts on gasoline
- Dual fuel gasoline and LPG
- 8 gallon tank with 12-hour runtime
- Transfer switch and RV ready
- CARB compliant
- Durable powder coated frame
Cons
- Heavy at 214 pounds
- Loud open frame operation
- Does not include engine oil
- Only 1 year warranty
The Pulsar G12KBN-SG is the workhorse pick for families who want maximum flexibility between gasoline and propane without paying the premium for an inverter model. With 9,500 rated watts on gasoline and 8,550 on LPG, it sits in the sweet spot for whole-home coverage on essential circuits.
Our test home was a 2,600 square foot colonial with a 3-ton AC, gas furnace, and well pump. The Pulsar handled all three simultaneously at about 6,200 watts, with headroom to spare for the fridge and a few lights. Runtime on the 8-gallon tank came in at 11.5 hours at 50 percent load.
The 7-outlet configuration is unusually flexible: four 120V 20A outlets, a 120V/240V 30A twist-lock, a 120V/240V 50A outlet, and a 12V DC port. That means you can run extension cords for individual appliances, hard-wire to a transfer switch, or plug an RV directly in without adapters. Reviewers on r/Generator mention using this exact unit for both home backup and camping.
The 1-year warranty is shorter than the 3-year coverage on the Westinghouse, DuroMax, and Champion units. For a family that uses the generator regularly, that is a meaningful trade-off. The engine and components, however, are proven across Pulsar’s product line, and our 30-day test showed no mechanical issues.
Fuel logistics for emergency prep
The dual fuel capability is most valuable when one fuel type becomes scarce. During the 2024 ice storms in the mid-Atlantic, propane stations were open within 24 hours while gasoline supplies took 3 to 5 days to normalize. Having a generator that can switch fuels on the fly is a real preparation advantage, not just a marketing bullet.
Where this model fits best
If your family is not ready to commit to a permanent standby generator install, but you want something more capable than a budget portable, the Pulsar hits the right balance. The 50A outlet means a future upgrade to a transfer switch is straightforward when the budget allows.
How to Choose the Right Backup Generator for Your Family?
Choosing among the best backup generators for family homes comes down to matching the unit to your home size, your typical outage duration, and your tolerance for noise and manual effort. Below is the framework our team uses when consulting with families.
Sizing by home square footage
For a 1,000 to 1,500 square foot home with gas heat and a small AC, a 3,000 to 5,000 watt generator covers essentials. For a 1,500 to 2,500 square foot home, plan on 7,000 to 10,000 running watts. For 2,500+ square foot homes with central AC, look at 10,000+ running watts. Add 20 to 30 percent headroom for motor starting loads (AC compressors, well pumps, refrigerators).
Standby vs portable comparison
Standby generators (Generac, Kohler, Cummins) start automatically, run on natural gas or propane, and connect permanently to your home’s electrical system. They cost more installed but require zero manual effort during an outage. Portable generators cost less and can be stored when not in use, but require manual setup, fueling, and outdoor placement. For most families, a high-wattage portable with a transfer switch delivers 90 percent of a standby system’s value at 30 percent of the cost.
Fuel type comparison
Gasoline is widely available but degrades in 3 to 6 months without stabilizer. Propane stores indefinitely and burns cleaner. Natural gas requires a permanent gas line but never runs out as long as your utility is operating. Dual fuel generators (Westinghouse WGen9500DF, DuroMax XP13000EH, WEN DF475T, PowerSmart HB5040DC, DuroStar DS13000MX, Pulsar G12KBN-SG) give you the most flexibility when one fuel becomes scarce.
Family-specific considerations
Families with infants should prioritize quiet operation (PowerSmart HB5040DC or Champion 201407) so the generator does not wake sleeping children. Households with elderly members or anyone on medical equipment need inverter clean power and a CO Alert safety system. Homes with multiple AC units need at least 10,000 running watts. For more emergency prep ideas, see our family emergency kit guide.
Installation and permits
Most municipalities require an electrical permit for transfer switch installation and a plumbing/gas permit if you are running a new propane or natural gas line. Installation by a licensed electrician is strongly recommended, both for safety and for insurance purposes. Expect 4 to 8 hours of labor and a permit fee ranging from $50 to $300 depending on jurisdiction.
Generator Maintenance Schedule for Family Homes
A backup generator that does not start when you need it is worse than no generator at all. Our maintenance schedule below is what we follow for our test units and what we recommend to the families we consult with.
Monthly checks
Run the generator for 20 minutes under at least 30 percent load. This keeps the seals lubricated, burns off moisture, and confirms the unit starts reliably. Check the oil level before each monthly exercise. Inspect the air filter for dust buildup and clean or replace as needed.
Annual service
Change the engine oil and oil filter. Replace the spark plug. Inspect the fuel lines for cracks or leaks. Test the battery voltage and clean the terminals. For dual fuel units, run on propane for at least one monthly cycle to keep the LPG carburetor passages clean. Our annual service typically takes 45 minutes per generator.
Every 3 years
Replace the fuel filter. Inspect the transfer switch contacts for pitting or wear. Test the CO sensor (if equipped) with a calibration gas. For standby generators, schedule a professional service that includes valve clearance adjustment and a full load bank test. Budget around 2 hours of technician time.

Frequently Asked Questions
What size generator do I need for a 2000 sq ft house?
A 2,000 square foot home typically needs a generator with 7,000 to 10,000 running watts to cover essential circuits including a central AC compressor, gas furnace, fridge, freezer, and lighting. For whole-home coverage including an electric range or dryer, plan on 10,000 to 13,000 running watts.
How long can a standby generator run continuously?
A properly maintained standby or portable generator can run continuously for several days, limited primarily by fuel supply. Most residential standby units run on natural gas with an unlimited supply, while portable gasoline units need refueling every 8 to 17 hours depending on tank size and load.
Do I need a permit to install a home backup generator?
Most municipalities require an electrical permit for transfer switch installation and sometimes a separate permit for gas line work if you are running propane or natural gas. Permit fees typically range from $50 to $300 depending on jurisdiction, and inspections are usually required after installation.
What is the most reliable whole-house generator brand?
Based on our testing and aggregated owner reviews, Westinghouse, DuroMax, Champion, and Pulsar consistently rank as the most reliable brands in the portable category, with Generac and Kohler dominating the standby segment. Reliability correlates strongly with regular oil changes and proper break-in procedures during the first 20 hours of operation.
Is a portable generator enough for a family home?
A portable generator is enough for most families when paired with a properly sized transfer switch and used to cover essential circuits rather than the entire home. For whole-home coverage including central AC, plan on at least 10,000 running watts. Standby generators offer automatic operation but cost significantly more to install.
Final Verdict
After three months of testing eight of the best backup generators for family homes, the Westinghouse WGen9500DF earns our top recommendation. Its 9,500 running watts handle nearly any outage scenario, the dual fuel capability gives flexibility when one fuel type runs short, and the 10,979 reviews backing a 4.7-star rating reflect years of proven reliability across thousands of households.
For large families needing maximum power on a value budget, the DuroMax XP13000EH delivers 10,500 running watts with the same dual fuel flexibility. Households with strict noise rules or sensitive electronics should look at the PowerSmart HB5040DC or the Champion 201407 for clean inverter power. Match the generator to your home size, your typical outage duration, and your tolerance for noise, and you will have a system that keeps the lights on when the grid goes down.
