Briggs & Stratton Generators: Models, Prices, Warranty & Are They Good?

Are Briggs & Stratton Generators Good?

Yes.

The current residential standby product range has several technically compelling attributes:

• competitive natural-gas output
• strong motor-start capability
• 120/240V residential models
• Vanguard engines
• optional power management
• automatic transfer equipment
• remote monitoring
• substantial warranty coverage

The current manufacturer catalogue includes PowerProtect and PowerProtect+ residential standby equipment at several capacities, with 13, 18, 22 and 26 kW models represented across the current range.

That is enough depth to treat Briggs & Stratton as a proper residential standby brand rather than a fringe alternative.

What we cannot responsibly say is:

“Briggs & Stratton is more reliable than Generac.”

We do not have credible population-level current failure-rate evidence proving that.

Generator reliability also depends heavily on:

• installation
• fuel system
• battery
• maintenance
• controller
• transfer equipment
• local servicing

So the practical question is:

Does the Briggs system fit your load, fuel and local service market better than the alternatives?

Current Briggs & Stratton Home Standby Generators

The current residential catalogue is slightly more complicated than a simple four-model ladder because Briggs & Stratton now shows overlapping:

• PowerProtect
• PowerProtect DX
• PowerProtect+
• PowerProtect+ DX

product families.

That means you should compare the exact model number, not merely the headline capacity.

Current core capacities include:

• 13 kW
• 18 kW
• 22 kW
• 26 kW

The manufacturer also currently lists PowerProtect+ variants at 18, 22 and 26 kW.

Briggs & Stratton PowerProtect Generator Sizes

Useful current examples include:

*Manufacturer equipment MSRP where currently published; installation, ATS and other project costs can be additional.

The standout specifications are the 18 and 22 kW NG ratings.

Briggs & Stratton Natural Gas Output

Natural-gas performance is probably the most commercially interesting reason to compare Briggs & Stratton.

PowerProtect 18 kW

Current manufacturer rating:

• 18 kW LP
• 18 kW NG.

PowerProtect 22 kW

Current manufacturer rating:

• 22 kW LP
• 22 kW NG.

PowerProtect 26 kW

Current manufacturer rating:

• 26 kW LP
• 24 kW NG.

PowerProtect 13 kW

Current manufacturer rating:

• 13 kW LP
• 11.5 kW NG.

So Briggs does not completely eliminate natural-gas derating across every model.

But its current 18 and 22 kW products do retain full nameplate output on natural gas.

That is unusual enough to matter.

What Is Briggs & Stratton NGMax?

NGMax is Briggs & Stratton's branding around higher natural-gas power output.

The manufacturer specifically positions NGMax as a way to reduce the usual capacity penalty that appears when some standby generators operate on NG rather than LP.

Strip away the marketing language and the buyer benefit is simple:

you may get more usable generator capacity from the same nominal generator size when running natural gas.

For example:

A current Briggs & Stratton 22 kW:

22 kW NG

versus the current Generac Next Generation 22 kW already researched on this site:

21 kW NG

and some older/current competing 22 kW products are lower still.

A 1 kW difference is not enough to choose an entire brand by itself.

But if the house sits near a sizing threshold, it can matter.

Briggs & Stratton 22 kW: Why It Is Interesting

The current PowerProtect 22 kW is arguably the most interesting mainstream Briggs model.

It currently provides:

• 22 kW LP
• 22 kW NG
• 91.7A running current
• 100A breaker
• 120/240V
• 993cc Vanguard engine
• 45 kVA published motor-start capability
• 465 lb
• 68 dB(A) published operating sound
• seven-year comprehensive warranty on the represented model
• $6,037 starting MSRP.

For a natural-gas homeowner comparing 22 kW-class systems, I would absolutely quote this against Generac.

Not because Briggs automatically wins.

Because the fuel-specific output is genuinely competitive.

Briggs & Stratton 26 kW Generator

The current PowerProtect 26 kW is the high-capacity air-cooled option.

Current specifications include:

• 26 kW LP
• 24 kW NG
• 108.3A LP
• 100A NG
• 125A breaker
• 993cc Vanguard engine
• 65.5 kVA published motor-start capability
• 540 lb
• 65 dB(A) published normal operating sound
• $6,970 current starting MSRP on the represented PowerProtect listing.

Briggs currently describes it as its highest-capacity air-cooled home standby model.

The important figure for a natural-gas buyer is still:

24 kW NG.

Not 26.

Briggs & Stratton PowerProtect+ Generators

Briggs & Stratton is also currently pushing the newer PowerProtect+ line.

The current PowerProtect+ range represented on the manufacturer's site includes:

• 18 kW
• 22 kW
• 26 kW

plus DX variants.

PowerProtect+ emphasises:

• high motor-start performance
• front-facing exhaust
• updated enclosure/weather protection
• built-in EnergyTrak remote monitoring
• Vanguard engines.

The current PowerProtect+ 26 kW, model 040807, is rated at:

• 26 kW LP
• 24 kW NG
• 125A breaker
• 993cc Vanguard engine
• 545 lb
• 67 dB(A)
• $7,336 MSRP
• seven-year warranty on the represented non-DX model.

So again:

verify the exact series and SKU in the quote.

PowerProtect vs PowerProtect+ vs DX

This is where the Briggs range can become confusing.

Current manufacturer pages expose multiple overlapping families.

The cleanest way to think about them is:

PowerProtect

Current mainstream residential standby family.

PowerProtect+

Newer/enhanced product family emphasising stronger motor starting, front-facing exhaust, EnergyTrak integration and enclosure improvements.

DX

Dealer-specific configurations with enhanced warranty positioning on current represented products.

For example, Briggs currently promotes PowerProtect+ DX 26 kW with a 10-year dealer-exclusive warranty covering parts, labour and travel, while the non-DX PowerProtect+ 26 kW page publishes a seven-year warranty.

That means:

do not publish or accept “Briggs generators have a X-year warranty” as a universal statement.

The exact product family matters.

Briggs & Stratton Generator Warranty

Warranty is one of Briggs & Stratton's strongest marketing positions, but it needs precise handling.

Current manufacturer pages show different warranty terms across models/families.

Examples:

PowerProtect 13 kW

Current page:

7-year comprehensive warranty.

PowerProtect 18 kW

Current page:

7-year comprehensive warranty.

PowerProtect 22 kW

Current page:

7-year comprehensive warranty.

Current PowerProtect 26 kW listing

Current page:

10-year comprehensive warranty.

PowerProtect+ 26 kW

Current non-DX page:

7 years.

PowerProtect+ DX 26 kW

Current page promotes:

10-year dealer-exclusive warranty, including parts, labour and travel subject to the actual terms.

So the correct buying advice is:

get the exact warranty document attached to the exact generator SKU being quoted.

Do not buy from a generic “10-year Briggs warranty” sales claim.

Briggs & Stratton vs Generac

For most homeowners nationally, Generac remains our default starting point because its residential standby ecosystem and dealer familiarity are extremely broad.

But Briggs & Stratton has a very credible counterargument on natural-gas capacity.

For example:

Current Briggs PowerProtect 22 kW

• 22 kW NG
• 22 kW LP.

Current Generac Next Generation 22 kW

• 21 kW NG
• 22 kW LP

So Briggs gives approximately:

1 kW more NG capacity

in that specific comparison.

At 26 kW:

Briggs PowerProtect 26

• 24 kW NG
• 26 kW LP.

Current Generac Next Generation 26

• 24 kW NG
• 26 kW LP

There, the fuel-specific output is essentially equal.

The decision moves towards:

• installed price
• motor-start requirements
• ATS/load management
• warranty
• local dealer
• service response

Do not pick either brand from the logo.

Briggs & Stratton vs Kohler

Kohler/Rehlko remains a serious competitor, particularly where the local Kohler dealer is excellent or larger liquid-cooled capacity matters.

But current Briggs natural-gas ratings create useful comparisons.

For example:

Briggs 22 kW

• 22 kW NG
• 22 kW LP.

Kohler 20RCA

Current project research:

• 18 kW NG
• 20 kW LP

These aren't identical product capacities, so don't pretend this is a perfect head-to-head.

The useful point is that Briggs' current NGMax equipment competes aggressively on actual natural-gas output.

If the home's fuel is NG, compare NG kW, not model names.

Briggs & Stratton vs Cummins

Cummins is also strong on natural gas at certain capacities.

Current project research includes:

Cummins RS25

• 25 kW NG
• 25 kW LP

Briggs PowerProtect 26

• 24 kW NG
• 26 kW LP.

So in that comparison:

Cummins wins NG output by 1 kW

while:

Briggs wins LP output by 1 kW.

That's exactly why this site uses fuel-specific ratings.

A “26 kW” machine does not automatically produce more power than a “25 kW” competitor on the fuel you actually use.

Briggs & Stratton Motor Starting

This is another area where Briggs is pushing hard.

Current manufacturer specifications publish:

• PowerProtect 13 kW: 37 kVA motor starting
• PowerProtect 22 kW: 45 kVA
• PowerProtect 26 kW: 65.5 kVA at 35% voltage dip.

PowerProtect+ models are specifically marketed around high starting capability, including the ability of represented models to start large air-conditioning loads.

That can matter for:

• central AC
• well pumps
• compressors
• other motor loads

But don't reduce motor-start sizing to one marketing number.

Actual equipment starting characteristics still matter.

Can a Briggs & Stratton Generator Run Central AC?

Yes, appropriately sized models can.

The bigger question is:

what does the AC require at startup?

Briggs & Stratton has clearly engineered the current residential line around strong motor starting.

That makes the brand particularly relevant for houses with:

• central AC
• heat pumps
• well pumps

But the complete load calculation still needs to include everything else operating at the time.

Use our generator size calculator.

What Is Symphony Choice Power Management?

Symphony Choice is Briggs & Stratton's current optional power-management architecture.

It allows the generator system to prioritise and manage high-demand household loads rather than requiring a generator large enough to run everything simultaneously.

Current modules include:

Low Voltage Module

Designed to manage high-wattage equipment through low-voltage control.

50 Amp Module

Can manage 120V or 240V appliances including loads such as:

• electric stove
• oven
• electric heat

Low Voltage Dual Module

Can control two thermostatically controlled appliances, such as two AC units.

The commercial benefit is simple:

load management can sometimes save more money than buying a larger generator.

Should You Buy a Bigger Briggs Generator or Use Load Management?

Use the load calculation.

If a 22 kW generator covers normal outage demand but one occasional appliance pushes the theoretical maximum to 25 kW, spending thousands to move to another system may be unnecessary.

It can be smarter to manage:

• second AC
• water heater
• range
• pool load

so they do not all operate simultaneously.

Briggs itself positions Symphony Choice as a way to use a smaller generator while prioritising household power.

Bigger isn't always the clever answer.

Briggs & Stratton EnergyTrak Monitoring

Current Briggs equipment uses EnergyTrak for remote monitoring.

On supported systems, EnergyTrak can allow:

• remote generator status monitoring
• alerts
• installer remote diagnostics/troubleshooting.

The current 13 kW page notes that a subscription is required for its represented EnergyTrak functionality.

Remote monitoring is useful.

But it should rank below:

• correct sizing
• fuel infrastructure
• competent installation
• local service

when choosing a generator.

Briggs & Stratton Eco-Cise Exercise Mode

Current PowerProtect models include Eco-Cise weekly exercise capability.

The represented 13 and 22 kW pages publish a short:

16-second default weekly test cycle.

The benefit is reduced:

• exercise noise
• fuel consumption
• unnecessary runtime

compared with a long weekly exercise cycle.

It is a nice ownership feature.

It is not a reason by itself to buy the generator.

Briggs & Stratton Generator Noise

Published current manufacturer examples include:

These are manufacturer specifications from represented current models.

Do not use those numbers to declare Briggs universally quieter than Generac, Kohler or Cummins without equivalent test conditions.

Installation location matters too.

Briggs & Stratton Generator Fuel Consumption

Current manufacturer half-load data gives useful examples.

PowerProtect 18 kW

At 50% load:

• LP: 193,000 BTU/hr
• NG: 176,000 BTU/hr.

PowerProtect 22 kW

At 50%:

• LP: 217,000 BTU/hr
• NG: 194,000 BTU/hr.

PowerProtect 26 kW

At 50%:

• LP: 235,000 BTU/hr
• NG: 206,000 BTU/hr.

Those figures matter for:

• fuel cost
• gas-line sizing
• meter capacity
• propane system design

Use the exact model's installation data for final fuel engineering.

Does a Briggs & Stratton Generator Need a Bigger Gas Meter?

Possibly.

The generator adds another major natural-gas load to the property.

The fuel system may already be serving:

• furnace
• water heater
• range
• fireplace
• pool equipment
• dryer

Adding a large standby generator can exceed existing meter, regulator or pipe capacity.

NGMax gives you useful electrical output.

It does not magically increase gas-pipe capacity.

See our natural gas generator guide.

Natural Gas or Propane for Briggs & Stratton?

Briggs makes natural gas particularly compelling because of its current NGMax ratings.

Natural Gas Is Strong When:

• adequate NG service already exists
• long utility-fed runtime matters
• avoiding fuel storage matters
• the model retains strong NG output

Propane Is Strong When:

• there is no NG service
• onsite stored fuel matters
• utility independence matters
• bulk propane is already installed

On the current 18 and 22 kW PowerProtect examples, there is no published output penalty on NG.

That makes the normal propane-output advantage less relevant on those exact models.

See our natural gas vs propane generator guide.

Briggs & Stratton Automatic Transfer Switches

Briggs & Stratton currently offers residential automatic transfer equipment including:

• 100A
• 150A
• 200A
• larger dual 200/400A configurations.

The correct ATS depends on the home's electrical-service architecture.

Do not assume:

22 kW generator = 100A service

or:

26 kW generator = 200A generator output.

Generator kW and ATS/service amperage solve different parts of the electrical design.

See our generator transfer switch guide.

Briggs & Stratton 13 kW Generator

The 13 kW stands out because it targets smaller installations and constrained sites.

Current specifications:

• 13 kW LP
• 11.5 kW NG
• 70A breaker
• 627cc Vanguard engine
• 315 lb
• 37 kVA motor starting
• $4,460 MSRP.

Briggs says the represented model can be installed as close as 18 inches from a building where the manufacturer's installation requirements are satisfied.

That is potentially useful on:

• smaller lots
• tighter side yards

But placement should still follow the exact installation manual and local requirements.

Briggs & Stratton 18 kW Generator

Current PowerProtect 18 kW specifications include:

• 18 kW LP
• 18 kW NG
• 80A breaker
• 993cc Vanguard engine
• 465 lb
• 68 dB(A)
• seven-year comprehensive warranty
• $5,746 starting MSRP.

The equal NG/LP output is the main reason this model deserves attention.

If a load calculation lands around this class and the home runs on NG, compare it against nominally larger competitors on their actual NG rating.

Briggs & Stratton 22 kW Generator

For many homes, this is the sweet spot.

Current PowerProtect:

• 22 kW LP
• 22 kW NG
• 100A breaker
• 45 kVA motor-start rating
• $6,037 MSRP.

If I were comparing mainstream NG standby systems today, this is the Briggs model I would pay particular attention to.

Briggs & Stratton 26 kW Generator

This is for homes that genuinely need more capacity.

Current PowerProtect:

• 26 kW LP
• 24 kW NG
• 125A breaker
• 65.5 kVA motor-start capability
• $6,970 starting MSRP.

The key is not to jump to 26 kW because it is the largest air-cooled option.

Buy it when the extra capacity solves an actual load problem.

Briggs & Stratton Generator Installation

A Briggs installation follows the same fundamental process as other permanent standby systems:

1. load calculation
2. generator selection
3. fuel selection
4. site planning
5. ATS/electrical design
6. gas or propane system design
7. permitting
8. installation
9. commissioning
10. ongoing maintenance

Current PowerProtect literature also highlights close-placement capability on represented products, but the exact manufacturer's installation manual controls.

See our whole-house generator installation guide.

Briggs & Stratton Generator Maintenance

Briggs standby generators are combustion engines and still require model-specific maintenance.

That can include:

• engine oil
• oil filter
• air filter
• spark plugs
• battery
• cooling/airflow inspection
• fuel-system inspection

Do not assume a seven- or ten-year warranty removes scheduled maintenance obligations.

The exact owner's manual for the model controls.

See our whole-house generator maintenance guide.

Briggs & Stratton Reliability

There is not a credible current population-level dataset allowing us to say:

Briggs fails X% less often than Generac

or:

Briggs lasts Y years longer than Kohler.

So we won't manufacture one.

Useful reliability signals include:

• current engine/platform design
• warranty
• installation quality
• dealer/service support
• maintenance
• fuel-system quality

Briggs & Stratton has more than a century of engine/power-equipment history, and its current Energy Solutions business manufactures standby-generator products in the United States.

That's meaningful brand context.

It is not a failure-rate study.

Briggs & Stratton Dealer and Service Network

This can decide the purchase.

A generator that looks fantastic on paper is a weak buy if:

• nobody local installs it properly
• parts/service are difficult
• emergency response is poor

Briggs currently maintains dealer/installer support and dealer-finding infrastructure for its standby products.

Before choosing the brand, ask:

• who services it locally?
• are they factory-authorised?
• do they stock common parts?
• what is their outage-season response time?
• who handles warranty labour?
• how long have they installed Briggs standby systems?

The dealer is part of the generator system.

Briggs & Stratton Pros and Cons

Pros

• excellent current natural-gas output at key capacities
• current 18 and 22 kW PowerProtect models retain full NG/LP rating
• strong published motor-start capability
• Vanguard engines on represented models
• Symphony Choice power management
• EnergyTrak remote monitoring
• short Eco-Cise weekly exercise
• strong current warranty positioning
• 13–26 kW mainstream residential range
• competitive current equipment MSRP

Cons

• product-family naming is currently more complicated than it needs to be
• warranty differs between PowerProtect, PowerProtect+ and DX configurations
• dealer coverage needs checking locally
• 13 and 26 kW still lose some output on NG
• no credible evidence supports calling Briggs universally more reliable than competitors
• complete installed cost matters far more than equipment MSRP alone

Who Should Buy a Briggs & Stratton Generator?

I'd shortlist Briggs aggressively when:

The Home Uses Natural Gas

This is the strongest case.

The current 18 and 22 kW equal NG/LP ratings are commercially meaningful.

The House Has Large Motor Loads

Briggs publishes strong motor-start capability across the represented range.

The Load Can Benefit From Symphony Management

Load management may allow a smaller system to cover the actual household requirement.

Local Briggs Dealer Is Excellent

Good hardware + good local support is a strong combination.

The Briggs Quote Is Better Than Generac/Kohler

Do not pay for a competitor badge if the Briggs system fits better and has stronger local support.

Who Should Skip Briggs & Stratton?

I would look elsewhere when:

Local Service Is Weak

This overrides several specification advantages.

The Competitor Quote Is Materially Better

Compare complete installation and service, not MSRP.

You Need Much Larger Liquid-Cooled Capacity

The main residential Briggs pages discussed here are concentrated around the air-cooled 13–26 kW range.

You're Buying Purely From Warranty Length

Warranty is good.

It isn't the system design.

Questions to Ask Before Buying a Briggs & Stratton Generator

1. Which exact model and series is this?
2. Is it PowerProtect, PowerProtect+ or DX?
3. What is the exact model number?
4. What is its NG output?
5. What is its LP output?
6. What calculated household load are we covering?
7. What is its motor-start capability?
8. Are you using Symphony Choice load management?
9. Which loads will be managed?
10. Which ATS is included?
11. Is EnergyTrak included and does it require a subscription?
12. What exact warranty applies to this SKU?
13. Does that warranty cover labour and travel?
14. Who performs warranty service locally?
15. What is the complete installed price?
16. Can my gas meter/regulator/piping supply the required load?

If the quote just says:

“Briggs 22 kW”

ask for more detail.
