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.

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

    • Solid unit, easy to assemble, 14500 surge, price. Read - solid review.
Style: 14.5KW Tri Fuel
Unit was delivered no issues. I unboxed to find a screw and a nut at the bottom of the box. I thought it was extra as I did not initially see where it was from. It took minutes to put on the wheels then the the bottom feet. One of the bottom feet holes had to be redrilled as one of the engine mounts was partially blocking a hole. Not a big deal. Drilled the hole, touched up with paint to prevent rust in the future as I plan to keep the generator for a long time. My past unit I have had for 21 years and it still runs. Then I noticed where the bolt that was in the box goes, so I installed it, engine mount. Put oil and a little fuel plugged in the battery and it was running. It came with some tools, good instructions and information. All in all I think it is well built, solid, a heavy unit with many options and a very good price. I was going to buy a Duromax, copper windings and all, but the reviews were not as good and more expensive. Also this unit has a surge of 14,500, running at 11,500 The little extra things that I had to do was not a big deal. We will see about longevity. I hope this review helps. I would have given it a 4.5, but I decided on a 5. ... show more
