More Details on Our Top Picks

  1. Generac GP9500E Tri-Fuel Portable Generator with Electric Start

    Generac GP9500E Tri-Fuel Portable Generator with Electric Start

    Best Tri-Fuel Portable Pick

    View Latest Price

    For homeowners who want a portable unit that can use whichever fuel is available, the Generac GP9500E stands apart from the fixed-fuel standby models here. It delivers 9,500 running watts on gasoline and can also run on propane or natural gas, giving buyers more ways to keep backup power going. Its 12,500-watt gasoline starting capacity can help handle brief startup surges, while electric start avoids repeated pull starts. Compared with the Westinghouse WGen9500DF, this model adds natural gas compatibility; the tradeoff is that its 219-pound weight makes moving it a two-person job for many households. It also needs to be positioned and operated as a portable generator, so it will not automatically restore power like the Honeywell 14 kW standby unit. Choose it for fuel flexibility and portable backup, not unattended outage coverage.

    Pros:
    • Runs on gasoline, propane, or natural gas
    • Provides 9,500 running watts and up to 12,500 starting watts on gasoline
    • Electric start, wheels, and folding handle simplify operation and repositioning
    • COsense shutdown, low-oil shutdown, and GFCI outlets add safety protections
    Cons:
    • At 219 pounds, it is heavy to move and store
    • Natural gas operation depends on access to a suitable gas connection
    • Unlike fixed standby units, it does not automatically start when utility power fails

    Best for: Homeowners who want strong portable backup and the option to use gasoline, propane, or an available natural gas connection

    Not ideal for: Buyers who need automatic, unattended outage response or a generator that is easy to move alone

    • Model:8063
    • Fuel types:Gasoline, liquid propane, natural gas
    • Running power:9,500 watts
    • Starting power:12,500 watts on gasoline
    • Engine:500cc Generac OHV
    • Fuel tank capacity:7.5 gallons
    • Runtime:Up to 9.5 hours at 50% load or 14 hours at 25% load on gasoline
    • Weight:219 lbs
    Our verdict
    “Choose the GP9500E if you want high-output portable backup with three fuel options and can manage setup during an outage.”
  2. Honeywell 14 kW Home Standby Generator with 16-Circuit Transfer Switch

    Honeywell 14 kW Home Standby Generator with 16-Circuit Transfer Switch

    Best Standby Pick for Essential Circuits

    View Latest Price

    The Honeywell 14 kW suits homeowners who want backup to begin automatically and prefer a defined circuit limit over sizing for every household load. Its included 16-circuit transfer switch helps direct power to selected essentials, while the composite mounting pad and weather-resistant aluminum enclosure address parts of the outdoor installation. Compared with the portable Generac GP9500E, this unit responds to an outage without someone wheeling out and starting a generator. Its 14 kW output is also higher than that portable model’s running output, though actual coverage depends on the home’s loads and circuit setup. The tradeoff is installation planning: it needs a compatible natural gas or propane supply, and the listed 120 V specification offers less voltage detail than some alternatives. Pick it for automatic essential-circuit coverage, not a plug-and-play backup.

    Pros:
    • Automatically starts when utility power is lost
    • Includes a 16-circuit transfer switch
    • Runs on natural gas or propane
    • Includes a composite mounting pad and weather-resistant aluminum enclosure
    Cons:
    • Requires a compatible fuel connection and installation work
    • A 16-circuit switch means buyers must plan which household loads receive backup
    • The listed 120 V specification provides limited detail for evaluating broader electrical compatibility

    Best for: Homeowners who want automatic backup for a planned set of up to 16 essential circuits and have a suitable fuel supply

    Not ideal for: Renters or buyers who cannot arrange permanent installation, fuel hookup, or circuit selection

    • Power output:14 kW
    • Fuel types:Natural gas, propane
    • Voltage:120 V
    • Frequency:60 Hz
    • Transfer switch:16-circuit
    • Dimensions:48 × 25 × 29 in
    • Enclosure material:Aluminum
    • Warranty:3-year limited
    Our verdict
    “Choose the Honeywell if automatic backup for selected household circuits matters more than portable use or whole-home sizing flexibility.”
  3. Generac 14kW Whole Home Generator, Cellular Capability

    Generac 14kW Whole Home Generator, Cellular Capability

    Best for Remote Monitoring

    View Latest Price

    The Generac 14 kW Whole Home Generator is a fit for owners who want automatic outage response with a way to check on the unit remotely. Its built-in cellular capability and Mobile Link app add visibility that the Honeywell 14 kW listing does not specify, while natural gas or propane operation provides fuel flexibility for a permanent installation. At 14 kW, it shares the Honeywell’s output class, so neither should be treated as guaranteed full-house coverage without matching generator capacity to household loads. The 391-pound weight and 46.4-by-26.3-by-30.7-inch dimensions point to a substantial installation rather than a movable backup. Remote features also come with a limit: full functionality requires a premium subscription. This pick makes most sense when monitoring access matters enough to justify that ongoing requirement.

    Pros:
    • Automatically detects outages and starts within seconds
    • Cellular capability supports remote monitoring and control through Mobile Link
    • Dual-fuel operation accepts natural gas or propane
    • 14 kW output can serve essential circuits or a properly sized home setup
    Cons:
    • Full remote functionality requires a premium Mobile Link subscription
    • At 391 pounds, it requires a substantial permanent installation
    • 14 kW output may not cover all household loads without careful sizing

    Best for: Homeowners with a permanent natural gas or propane setup who want app-based visibility into generator status

    Not ideal for: Buyers seeking a portable unit, avoiding subscription-dependent remote features, or expecting 14 kW to cover every home load without sizing

    • Power output:14 kW
    • Fuel types:Natural gas, propane
    • Voltage:240 volts
    • Frequency:60 hertz
    • Weight:391 pounds
    • Dimensions:46.4 × 26.3 × 30.7 in
    • Material:Stainless steel
    • Additional features:Automatic idle control, overload protection, fully enclosed design
    Our verdict
    “Choose this Generac if automatic backup and cellular monitoring are priorities and you are comfortable with permanent installation and subscription requirements.”
  4. Generac 22 kW Whole-Home Standby Generator with Transfer Switch and Cellular Connectivity

    Generac 22 kW Whole-Home Standby Generator with Transfer Switch and Cellular Connectivity

    Best for Higher Household Loads

    View Latest Price

    Among the fixed standby options in this batch, the Generac 22 kW offers the largest stated output, making it the stronger starting point for homes with more simultaneous electrical demand than the 14 kW Honeywell or Generac models can accommodate. Its automatic 200 A transfer switch is included, and cellular monitoring can send maintenance alerts, giving owners a more connected setup than the portable Westinghouse WGen9500DF. Cold-weather design features may also matter where snow and ice can complicate outdoor operation. The tradeoffs are the 451-pound installation weight and dependence on an LP or natural gas supply. Cellular remote monitoring requires a premium subscription, so the added connectivity has an ongoing condition. The 22 kW rating is not a substitute for a load assessment; match capacity and transfer equipment to the home before choosing it.

    Pros:
    • 22 kW output exceeds the 14 kW standby models in this batch
    • Includes an automatic 200 A transfer switch
    • Cellular monitoring supports status checks and maintenance alerts
    • Cold-weather features and a 5-year limited warranty are specified
    Cons:
    • Requires a permanent LP or natural gas supply
    • At 451 pounds, it is a substantial installation
    • Remote monitoring requires a premium Mobile Link subscription

    Best for: Owners of larger homes with higher concurrent loads who want automatic transfer, cellular alerts, and a permanent fuel connection

    Not ideal for: Households with modest backup needs, no LP or natural gas access, or no plan for professional installation and load sizing

    • Power output:22 kW
    • Voltage:240 V
    • Fuel types:LP or natural gas
    • Transfer switch:Automatic 200 A
    • Weight:451 lb
    • Dimensions:46.4 × 26.3 × 30.7 in
    • Materials:Aluminum, steel
    • Warranty:5-year limited
    Our verdict
    “Choose this 22 kW Generac for higher household demand and automatic standby operation when the fuel hookup, installation, and monitoring terms fit your plans.”
  5. Westinghouse 12500 Watt Dual Fuel Home Backup Portable Generator with Remote Electric Start, Transfer Switch Ready, Gas and Propane Powered

    Westinghouse 12500 Watt Dual Fuel Home Backup Portable Generator with Remote Electric Start, Transfer Switch Ready, Gas and Propane Powered

    Best Portable Pick for Remote Starting

    View Latest Price

    The Westinghouse WGen9500DF is the portable choice for buyers who value convenient starting and can work with gasoline or propane. Its key fob can start the generator from a distance, while the 9,500-watt gasoline running output matches the Generac GP9500E on that fuel. The Generac has the broader fuel menu because it also supports natural gas; this Westinghouse counters with stated propane output of 8,500 running watts and up to 12 hours of runtime at half load. GFCI outlets and transfer-switch-ready connections make it adaptable for home backup, but “ready” does not make it an automatic standby system: someone still needs to position and operate the generator, and a compatible transfer setup matters. Its bulk also undercuts the portability suggested by the category. Pick it for portable power with remote start, not seamless unattended coverage.

    Pros:
    • Remote electric start with key fob and recoil backup
    • Provides 9,500 running watts on gasoline and 8,500 on propane
    • GFCI outlets include transfer-switch-ready and RV-ready connections
    • Runs up to 12 hours at half load on gasoline
    Cons:
    • Does not support natural gas, unlike the Generac GP9500E
    • Requires manual setup and operation during an outage
    • Heavy, bulky construction can make repositioning difficult

    Best for: Homeowners who want portable gasoline or propane backup with key-fob starting and a compatible transfer-switch setup

    Not ideal for: Buyers who need natural gas operation, automatic outage response, or a generator they can easily move alone

    • Peak power, gasoline:12,500 W
    • Running power, gasoline:9,500 W
    • Peak power, propane:11,200 W
    • Running power, propane:8,500 W
    • Fuel types:Gasoline, propane
    • Engine displacement:457 cc
    • Fuel tank capacity:6.6 gallons
    • Runtime:Up to 12 hours at half load
    • Starting method:Electric start with remote key fob and recoil backup
    Our verdict
    “Choose the WGen9500DF if remote starting and dual-fuel portable backup suit you better than natural gas flexibility or automatic standby operation.”
  6. Generac Guardian 22 kW Home Generator with Transfer Switch and Wi‑Fi Monitoring

    Generac Guardian 22 kW Home Generator with Transfer Switch and Wi‑Fi Monitoring

    Best Overall

    View Latest Price

    Whole-home capacity and included transfer equipment make this Guardian a strong fit for households that want automatic backup without piecing together the core system. Its 22 kW output matches the newer Generac 22 kW Whole-Home Standby Generator with Cellular Connectivity, while this model pairs that capacity with a 200 A NEMA 3R transfer switch and Wi‑Fi monitoring. Mobile Link alerts can help owners keep tabs on readiness remotely, and the 5-year limited warranty adds a defined support period.

    The tradeoff is installation: at 466 pounds, this is a fixed standby system that calls for professional handling and a licensed electrician. Buyers who want cellular connectivity should compare it with the newer cellular models; those who value Wi‑Fi and an included transfer switch get a more straightforward package here. It also needs a suitable natural gas or LP supply.

    Pros:
    • 22 kW output is suited to broad residential backup needs.
    • Includes a 200 A NEMA 3R automatic transfer switch.
    • Mobile Link Wi‑Fi supports remote monitoring and alerts.
    • Runs on natural gas or LP and carries a 5-year limited warranty.
    Cons:
    • The 466-pound unit requires professional handling and installation.
    • Licensed electrical installation adds work beyond placing a portable generator.
    • Wi‑Fi connectivity may be less suitable than cellular monitoring where home internet is unreliable.

    Best for: Homeowners seeking 22 kW automatic backup with an included 200 A transfer switch and Wi‑Fi monitoring.

    Not ideal for: Buyers who need a portable generator, want cellular rather than Wi‑Fi monitoring, or cannot accommodate professional installation.

    • Output:22 kW
    • Fuel:Natural gas or LP
    • Voltage:240 V
    • Engine:Generac G‑Force 1000 Series, 999 cc
    • Transfer switch:200 A NEMA 3R
    • Weight:466 lb
    • Dimensions:50 × 27 × 29 in
    • Warranty:5-year limited
    Our verdict
    “Choose this Guardian if you want 22 kW standby capacity, an included 200 A transfer switch, and Wi‑Fi monitoring in one package.”
  7. Generac 14 kW Whole-Home Standby Generator with 200 Amp Transfer Switch and Cellular Connectivity

    Generac 14 kW Whole-Home Standby Generator with 200 Amp Transfer Switch and Cellular Connectivity

    Best for Smaller Backup Loads

    View Latest Price

    This 14 kW Generac is the lower-capacity standby choice in this group, with automatic outage response, a 200 A transfer switch, and cellular connectivity. It suits homes whose backup plan prioritizes essential systems and managed loads rather than running every large appliance at once. Compared with the Generac 22 kW Whole-Home Standby Generator with Cellular Connectivity, it offers less output, but households with modest demand may prefer that smaller capacity over sizing for a heavier load.

    Cold-weather support and oil-level sensors address readiness concerns, while cellular monitoring can reach the Mobile Link app without relying on home Wi‑Fi. The limitation is that app updates and alerts require a premium subscription. At 391 pounds, it is still a permanent installation, and the 14 kW rating makes load planning important for homes with electric heating, multiple air conditioners, or other high-draw equipment.

    Pros:
    • Automatically detects outages and starts supplying backup power.
    • Includes a 200 A automatic transfer switch.
    • Cellular connectivity supports remote monitoring through Mobile Link.
    • Oil-level sensors and cold-start features support readiness in cold conditions.
    Cons:
    • 14 kW provides less capacity than the 18 kW and 22 kW standby options.
    • Mobile Link updates and alerts require a premium subscription.
    • At 391 pounds, installation requires professional handling.

    Best for: Owners of modest-size homes who want automatic standby power for selected household loads and cellular monitoring.

    Not ideal for: Households expecting to run several high-draw appliances simultaneously or owners who do not want a subscription for remote app updates and alerts.

    • Output:14 kW
    • Fuel:Natural gas or LP
    • Voltage:240 V
    • Frequency:60 Hz
    • Transfer switch:200 A automatic
    • Connectivity:Built-in cellular; Mobile Link app
    • Weight:391 lb
    • Dimensions:46.4 × 26.3 × 30.7 in
    Our verdict
    “Pick this model for automatic backup of planned household loads when 14 kW is sufficient and cellular monitoring suits your setup.”
  8. Generac 22 kW Whole-Home Standby Generator with Cellular Connectivity

    Generac 22 kW Whole-Home Standby Generator with Cellular Connectivity

    Best for Cellular Monitoring

    View Latest Price

    For owners who want 22 kW of automatic standby power and remote access without depending on home Wi‑Fi, this Generac pairs a cellular connection with the Mobile Link app. It runs on natural gas or propane and includes oil-level sensing and cold-start support. Compared with the Generac Guardian 22 kW Home Generator with Transfer Switch and Wi‑Fi Monitoring, this option offers cellular connectivity, while the Guardian description specifically includes a 200 A transfer switch.

    The stated package also includes a 5-year limited warranty and 24/7 customer support. The compromise is ongoing access: remote monitoring and control require a premium Mobile Link subscription. At 451 pounds, it is a fixed installation rather than a flexible backup unit, and buyers should confirm transfer-switch arrangements for their installation because one is not listed in the supplied product data.

    Pros:
    • 22 kW output supports substantial residential backup loads.
    • Cellular connection enables remote monitoring and control through Mobile Link.
    • Runs on natural gas or propane.
    • Includes oil-level sensing, cold-start support, and a 5-year limited warranty.
    Cons:
    • Remote Mobile Link features require a premium subscription.
    • The 451-pound unit needs professional installation and handling.
    • Transfer switch inclusion is not stated in the supplied product details.

    Best for: Homeowners who need 22 kW standby output and want cellular remote monitoring where Wi‑Fi coverage is uncertain.

    Not ideal for: Buyers who want an explicitly included transfer switch or remote app features without a premium subscription.

    • Output:22 kW
    • Fuel:Natural gas or propane
    • Voltage:240 V
    • Connectivity:Cellular; Mobile Link app
    • Weight:451 lb
    • Dimensions:46.4 × 26.3 × 30.7 in
    • Enclosure materials:Aluminum and steel
    • Warranty:5-year limited
    Our verdict
    “Choose this model if cellular monitoring and 22 kW capacity matter more to you than an explicitly listed transfer switch or subscription-free app access.”
  9. Generac 18kW Whole Home Generator with Cellular Capability

    Generac 18kW Whole Home Generator with Cellular Capability

    Best Middle-Capacity Standby Pick

    View Latest Price

    18 kW sits between the 14 kW and 22 kW Generac standby options, giving this model a middle ground for homes that need more headroom than the smaller unit but do not require the listed 22 kW output. Automatic outage detection, dual-fuel operation, and cellular app access make it a fixed standby choice for owners who want the system to start without a manual setup. Compared with the Generac 14 kW Whole-Home Standby Generator with 200 Amp Transfer Switch and Cellular Connectivity, this model offers more rated output; the supplied details do not list a transfer switch, which that 14 kW option does include.

    Its cold-start features and engine sensors speak to readiness in harsher conditions. Cellular monitoring requires a paid Mobile Link premium subscription, and the 426-pound weight points to professional installation. One listed starting-wattage figure appears inconsistent with the 18 kW output, so buyers should confirm the rating with the manufacturer before sizing loads.

    Pros:
    • 18 kW output provides more capacity than the 14 kW standby model.
    • Dual-fuel operation supports natural gas or propane.
    • Automatic outage detection and cellular Mobile Link access support hands-off monitoring.
    • Cold-start features and engine sensors support readiness in harsh conditions.
    Cons:
    • Cellular monitoring features require a paid Mobile Link premium subscription.
    • The 426-pound weight makes professional installation likely.
    • Transfer switch inclusion is not stated, and the supplied starting-wattage figure needs confirmation.

    Best for: Homeowners who need a capacity step up from 14 kW and want dual-fuel standby operation with cellular monitoring.

    Not ideal for: Buyers who need a stated included transfer switch, want to avoid a monitoring subscription, or need confirmed starting-output figures before purchase.

    Our verdict
    “Consider this 18 kW model for a middle-capacity standby system, after confirming its starting rating and transfer-switch configuration.”
  10. Westinghouse 14500 Peak Watt Tri-Fuel Home Backup Portable Generator with Remote Electric Start and Transfer Switch Ready

    Westinghouse 14500 Peak Watt Tri-Fuel Home Backup Portable Generator with Remote Electric Start and Transfer Switch Ready

    Best Portable Alternative

    View Latest Price

    This Westinghouse is the only portable generator in this batch, so its appeal is flexible placement and three fuel choices, not automatic whole-home standby operation.

    Best for: Homeowners who want a portable backup for selected appliances, need gasoline as a fuel option, and may also use the generator at a job site.

    Not ideal for: Buyers who want automatic whole-home outage coverage, a fixed 200 A transfer switch, or many direct outlet connections.

    • Peak output:14,500 W
    • Running output:11,500 W
    • Fuel:Gasoline, propane, or natural gas
    • Engine displacement:550 cc
    • Fuel tank:9.5 gal
    • Gasoline runtime:Up to 19 hours
    • Voltage:240 V
    • Ignition:Electronic; remote electric start
    Our verdict
    “Choose this Westinghouse if portability and tri-fuel flexibility matter more than automatic standby operation.”

    Best for Versatile, Portable Backup Power

    View Latest Price

    This portable generator provides ample power for emergency or recreational use, with dual-fuel capability and a long runtime.

Factors to Consider When Choosing Home Standby Generators

Choosing the right home standby generator involves understanding several key factors beyond just power output. Each home has unique requirements, so it’s important to consider how much backup power you need, the fuel type that fits your setup, and the installation complexity involved. Other critical considerations include system automation, connectivity features, and overall cost of ownership. Making informed decisions on these aspects can prevent costly mistakes and ensure your generator serves you well during outages.

Power Capacity and Home Size

Matching your generator’s capacity to your home’s electrical demands is essential. Larger homes with multiple appliances require higher wattage units, while smaller residences can opt for more modest models. Oversizing can lead to unnecessary costs and complexity, but undersizing risks insufficient backup during outages. Carefully assess your essential circuits and total power needs to select a generator that balances capacity with cost-efficiency.

Fuel Type and Availability

Generators typically run on natural gas, propane, or gasoline. Natural gas and propane are preferable for home standby units because they offer continuous supply and require less manual refueling, unlike gasoline-powered portable units. However, fuel availability depends on your local infrastructure, which can influence long-term operation costs. Consider your home’s existing connections and fuel delivery options when choosing a fuel type to avoid running out during prolonged outages.

Automatic Transfer Switches and Connectivity

Automatic transfer switches enable your generator to activate instantly when power fails, providing seamless backup. Advanced models include cellular or Wi-Fi connectivity, allowing remote monitoring and control—features that add convenience and peace of mind. While these extras increase upfront costs, they can reduce maintenance efforts and improve reliability, especially for those who want real-time updates without manual checks.

Installation and Maintenance

Proper installation is critical for safe and reliable operation. Larger units often require professional installation, which can add to the initial investment. Maintenance needs vary; some generators feature self-diagnostic systems and remote monitoring, simplifying upkeep. Remember, choosing a model with features suited to your technical comfort level can minimize ongoing hassle and ensure longevity.

Budget and Long-term Value

While initial costs are important, consider the total cost of ownership, including fuel, maintenance, and potential repairs. Premium models with advanced features may cost more upfront but can offer savings over time through better efficiency and remote diagnostics. Conversely, budget options might suffice for small homes with limited backup needs but could lack durability or advanced features for larger households.

Frequently Asked Questions

How do I determine the right wattage for my home generator?

Determining the appropriate wattage involves listing all essential appliances and circuits you want to power during an outage. Add up their running wattage requirements, then include a buffer for startup surges, especially for motor-driven devices. Consulting a professional electrician can help you accurately assess your needs and select a generator that provides reliable backup without overspending on capacity you don’t need.

Can I install a home standby generator myself?

Installing a home standby generator requires a licensed professional due to electrical code compliance and safety considerations. The process involves connecting to your home’s electrical system, gas lines, and ensuring proper ventilation. Attempting a DIY installation can lead to safety hazards, void warranties, and violate local regulations. Hiring experienced installers ensures the system operates safely and reliably when needed.

What maintenance does a home standby generator require?

Regular maintenance includes checking oil levels, inspecting filters, and running periodic tests to ensure readiness. Many modern models feature automatic diagnostics and remote monitoring, simplifying upkeep. It’s advisable to schedule professional inspections annually, especially before storm seasons, to verify fuel connections, battery health, and overall system performance. Proper maintenance extends the lifespan and guarantees reliable operation during outages.

Are there noise concerns with home standby generators?

Yes, standby generators can produce significant noise during operation, which might be disruptive depending on your proximity to neighbors or your home’s insulation. Many newer models incorporate sound-dampening features or quieter engine designs to reduce noise levels. When choosing a generator, consider the noise ratings and installation options like sound barriers or enclosures if noise is a concern.

How long can a home standby generator run continuously?

The runtime of a generator depends on its fuel capacity and load. Most models can operate for several hours—often 8 to 12 hours—on a full tank, but high loads or smaller fuel tanks reduce this duration. For prolonged outages, supplemental fuel supply or automatic refueling systems are options to consider. Planning for extended outages ensures your generator can sustain critical power needs without frequent refueling.

Conclusion

For homeowners seeking a reliable, hands-off backup power solution, the Generac 24 kW Whole-Home Standby Generator stands out as the best overall choice, especially for larger households. Those prioritizing value might prefer the Honeywell 14 kW Model, offering solid features at a more accessible price. If budget isn’t a concern and you desire the latest technology, the Generac 22 kW with Cellular Connectivity provides advanced remote monitoring and control. Beginners or small households may find portable options like the DuroMax XP13000HX suitable, though they require manual setup. Ultimately, your choice depends on your home size, budget, and desired features—this guide aims to match you with the best fit.
