Quick answer: Harbor Freight is finally entering the whole-house standby market. At SEMA in November 2026 the company previewed the Predator 28kW home standby generator, a dual fuel unit that connects to a propane or natural gas line and comes packaged with a 200-amp automatic transfer switch. It reaches stores in fall 2027, and no price has been announced. The output number alone tops the biggest air-cooled Generac, which is why standby shoppers are already paying attention a year ahead of launch.
For years this site has told readers the same thing: Predator is a portable brand, full stop. Our Predator generator review covers the portables that made the name, and the standby conversation always ended at "they don't make one." That sentence is now officially outdated.
Predator 28kW: what Harbor Freight actually announced
The announcement came from Harbor Freight's own newsroom during SEMA in Las Vegas, and the wording matters. This was a preview, not a launch. The generator was shown on the show floor, specs were published, and the company committed to one availability window: fall 2027, in stores and online, sold only at Harbor Freight.
Everything below comes from that announcement. Where something is unknown, we say so rather than guess, because there is a year of speculation ahead of us and most of it will be wrong.
Confirmed specs on the Predator 28kW home standby generator
Here is what Harbor Freight has put on paper so far:
- 28,000 running watts, whole-home standby class
- Dual fuel: connects to a residential propane or natural gas supply
- 24-volt electric starting system
- 200-amp automatic transfer switch included in the package
- Low-THD alternator with copper windings for sensitive electronics
- Oil sensors that continuously monitor level and pressure
- Built-in Wi-Fi and Bluetooth for remote monitoring and alerts
- Starts within seconds of detecting a power loss
- 5-year limited warranty
Two of those lines deserve more attention than they will probably get. The bundled 200-amp transfer switch removes a purchase decision that confuses most first-time standby buyers, since the switch alone typically adds $500 or more when it is not bundled. And the 5-year warranty matches what Generac puts on its Guardian line, which tells you Harbor Freight is not planning to treat this as a disposable product.
The 24-volt starting system is the interesting part
Most air-cooled standbys start on a 12-volt system. Harbor Freight went with 24 volts instead, and that is not a spec-sheet footnote. Higher cranking voltage means more confident cold starts and less current through the wiring for the same starter torque, which matters most on a machine that may sit idle for months and then has to fire up during an ice storm.
It also suggests Harbor Freight engineered this unit rather than rebadging an existing factory design. Whether that engineering holds up over a decade of service is exactly the kind of question nobody can answer before the first units ship, and we will not pretend otherwise.
How it compares to Generac and Kohler standby units
On raw output, 28kW puts Predator above the Generac Guardian 26kW, currently the largest air-cooled standby you can buy, as our Generac Guardian 26kW review details. That Generac derates to about 22,500 watts on natural gas, and Predator has not published its own derate numbers yet, so treat any "biggest in class" crowning as premature until both figures are on the table.
Kohler's air-cooled range tops out around the same 26kW mark, with a reputation built on commercial-grade engines rather than headline wattage. What all three brands now share is the 200-amp automatic transfer switch pattern, so the practical differentiators will be price, dealer-installer availability, and long-term support. Harbor Freight's store network is enormous, but standby generators need licensed installers, and that is infrastructure the brand has never had to build before. Our generator comparison page tracks how these lineups stack up as the market shifts.
What we still do not know
The honest gaps, as of the SEMA preview:
- Price. Nothing announced. Harbor Freight calls it "an incredible value," which is marketing, not a number.
- Natural gas output. Propane figures lead; NG derates are unpublished.
- Noise rating. No decibel figure yet.
- Installation program. No word on installer partnerships, permitting help, or financing.
- Engine origin and service parts. Unknown, and it is the question that decides how the value story ages.
Anyone who quotes you a firm price or a decibel number today is making it up.
Should you wait for the Predator 28kW or buy a standby now
If you need backup power before fall 2027, waiting is not a plan. Outage seasons do not respect product calendars. A house that loses power for days at a time needs a solution this year, and you can check that pattern for your own area in our power outages by state data. The current market already has capable answers in the 20kW to 26kW class, and our guides on what size generator for a 2800 square foot house and where to buy a generator walk through sizing and purchasing without waiting on a preview.
If your timeline is late 2027 anyway, this launch is worth watching closely. A value-brand entrant with a bundled transfer switch and a 5-year warranty has real potential to pressure installed pricing across the whole category, the same way Predator portables forced the portable market to sharpen its numbers. Run your loads through the generator size calculator now so you know exactly what class you need when the price lands.
FAQ
How much will the Predator 28kW home standby generator cost?
No price has been announced. Harbor Freight's positioning language points at value pricing, and the bundled 200-amp transfer switch removes a $500-plus add-on, but any specific dollar figure you see online today is speculation. Real pricing should surface closer to the fall 2027 launch.
When can you actually buy one?
Fall 2027, in Harbor Freight stores and online. The generator is exclusive to Harbor Freight, and no preorder program has been announced.
Will 28kW run a whole house?
For most homes, yes, with headroom to spare. That output class covers two air conditioner stages, electric water heating support, and normal household loads together. Sizing still depends on your actual appliances, so verify with a load calculation before buying any standby unit.
Is Predator reliable enough for a standby generator?
The portable track record is genuinely decent for the price, but portables and standbys are different engineering problems, and a machine that must auto-start after sitting for months is the harder test. The 5-year warranty is a good signal. A real verdict will take a year of owner data after launch.
Bottom line
The Predator 28kW home standby generator is the most interesting standby market development in years: a value brand jumping straight to the top of the air-cooled output chart with a bundled 200-amp switch and a warranty that matches Generac. It is also a preview with no price, a year-plus wait, and an unproven service network. Buy on your outage calendar, not on a press release, and we will update this page as confirmed details arrive.
