Description

Remember when your backup plan had a backup plan? Whether we're providing your home electricity during a crisis or charging your family's cellphones at the campgrounds, WEN has been reliably lighting up lives since 1951. Now, with the WEN 14500-Watt Tri Fuel Electric Start Generator, you’ll be able to pull power from three different sources. Simply select your preferred method – gasoline, propane, or natural gas – and power on. With 14500 surge and 11500 running watts on gasoline, 12500 surge and 10300 running watts on LPG, and 10500 surge and 8750 running watts on NG, it’s durable enough for the job site and reliable enough for home emergency backup. Electric start lets you power up your generator with the turn of a key, and includes a recoil starter as backup. Our packed panel features four three-prong 120V NEMA 5-20R outlets, a 120V/240V 30A NEMA L14-30R outlet, a 120V/240V 50A NEMA 14-50R outlet, and a standard 12V DC automotive outlet. The onboard data meter digitally displays voltage, frequency, total runtime, and session runtime to help keep tabs on maintenance intervals. Run your lights, TV, refrigerator, sump pump, power tools, or other essentials with ease. The wheel and handle kit makes transportation easier than ever, while the included six-foot LPG hose allows for immediate connection to propane tanks. Thanks to its 240V capability, powerful 500cc engine, and included NG quick-connect adapter, this generator is the perfect portable alternative to hefty and expensive standby units (NOTE: NG hose not included / sold separately, part no. TF1450X-1431). Simply connect the NEMA L14-30R or 14-50R outlet to your transfer switch for power when and where you need it. Fill the gas tank with up to 8.2 gallons of gasoline for a half-load runtime of up to 12 hours. Compatible with the WEN 56413 Generator Cover and the WEN GNA273 Magnetic Dipstick. And because it’s a WEN product, your generator comes backed by a three-year limited warranty, a nationwide network of skilled service technicians, a stocked inventory of replacement parts, and a friendly customer helpline. Remember when you didn’t have to worry about the power going out? Remember WEN.

    • Very good

This generator exceeded my expectations. It starts easily, runs smoothly, and provides plenty of power for my needs.

    • Easy set up
Size: 14.5KW Tri-Fuel
I bought this 14,500 watt to power my house during hurricane season. I set it up, which only took about an hour, with the NG hose and added a gas regulator and shut off valve with the quick coupler. It purrs like a lion, not real bad though. It started right up, no hiccups at all. I later tested it by turning off the utility power and transferred to generator with the lockout plate available from Amazon. Ran all lights, fans, refrigerators and A/C without and problem. I’m really impressed with it, electric start and all the charging options on it also. Nice unit, definitely worth the price and does a good job for my 2100 sq. ft. house. ... show more

Size: 14.5KW Tri-Fuel
I haven’t had to use it for a power outage yet. The 2 gentleman who delivered it did a great job and the packaging of the generator was excellent. I’m assuming it came from the manufacturer that way. I was impressed. The directions were simple and easy to read and follow. I followed the directions and the unit fired right up. I’d say the experience was excellent. I’m happy. So far so good. ... show more

Size: 14.5KW Tri-Fuel
I purchased this generator from Amazon and it was delivered within 48 hrs with no hassles, uncrated a very sturdy packaging, assembled it and was very pleased with how well thought out that process was. The unit appears to be well constructed and I have plans to construct a concrete pad enclosure for it, as well as install an ATS for power transfer so my wife and kids don’t have to worry about an outage during hurricane season here in Florida. ... show more

    • False Advertising; Fake specs; Specified wattage is not possible; Unit shipped with bad battery
Size: 14.5KW Tri-Fuel
Review Image by Jeff C.
Review Image by Jeff C.
As title states, there is no way for the output of this unit to provide up to 11,500 watts (running) on gasoline or 10,300 watts (running) on propane. The main breaker built into this generator is 39 amps (9,360 watts @240v). This is presented on the wiring diagram reference in the manual. I run my unit on Natural gas and only expect it to deliver up to 8,750 running watts. Additionally, under no fuel option can you expect the “surge” capacity stated. I am filing formal complaints with the Federal Trade Commission, the Consumer Product Safety Commission, and my State Attorney General’s Consumer Protection Division regarding the misleading and inaccurate power ratings advertised and name-plated for this generator. The product’s breaker rating clearly contradicts the stated wattage specifications, which constitutes deceptive marketing and a potential safety concern. The unit has worked long enough for the initial startup procedure and a simulated 4 hour outage. I have a dedicated location established for a generator where this unit is kept for storage with both the generator cover and a second cube cover shield. For operation, both covers are removed, fuel and electrical connections are made, and a flip down roof is positioned to keep rain off. My unit shipped with a bad SLA battery. After noting the labored starts with the supplied battery, I used a lab bench top power supply to diagnose the battery and carefully monitor voltages and amperage. For the 12v SLA battery, I originally started the charge testing at 14.1v at 2 A constant current. As a result, active charge voltage measurement at the battery terminals and bench top PSU would never exceed 12.33 volts, and upon rest the battery voltage would only be 11v. This is a clear sign of cell failure and explains the inability for the battery to support the starting load. I tried several recovery procedures to restore the bad cell(s) without success. ... show more

    • Best generator ive ever owned
Size: 14.5KW Tri-Fuel
I live off grid... 100% off grid and ive bought several large brand name generators, none lasted even through the first operations because if a plastic part snapping, or week of operation from a bad carb system (im a retired diesel mechanic so it wasnt user error). Not one could last for longer than a year without a ton of constant carb clesning, plastic component replacements. I intentionally waited before writing a review for this reason. This is an amazing and life saving product. Has a smaller gas tank than the other models but its the literal only complaint I have. I prefer the key start to the push start because of the longevity of the parts involved. Ive replaced so many push start buttons across units. Its easy to change the oil, easy to start, to swap fuel modes and came with the best set up and operation guide ive seen on the market this far. Just buy it.... its worth it. ... show more
