WGEN12000DF

I said in another review how much I enjoyed this great generator running on gas but it wouldn't run on propane. I said I would update that review when the issue was resolved. It was and I am happy to say that this great generator runs GREAT on propane! It took a little of this and that but basically Lowes exchanged my first one with a second one and I couldn't be happier. I have to add that Westinghouse was going to exchange it out also but since I bought it from Lowes it was better this way. Thank you Lowes And Westinghouse for your superior customer service! My home is now more than ready with quality backup power.

Great generator (beast)

I just purchased the Westinghouse WGEN12000DF generator After my electrician visited to install my transfer panel, I hooked everything up and started my generator, Everything was wonderful. 60g 4500W hot water tank, 12000btu ductless heat pump, kitchen light and small round stove, TV and computer all worked like a charm with the low THD -5%. I'm ready for the next storm and the next power outage. Just one problem, have some friends with you so you can get this generator out of its wood create. Be careful when you connect sensitive electronic devices such as a heat pump you cannot use the low idles. Variation with the Herz. This should be indicated on the product sheet.

So far so good......

Just received and setup the generator. Overall its a very nice unit. Had my electrician put a hookup on my home to plug this into when power goes out....and I say "when" because it happens too often. Fairly quiet for the engine size, looks good, lots of connections. After setup I ran it for a bit just as a test. My electrician is coming back to test it on the house once my adapter cord arrives. A few items that I noticed while getting this setup which need to be addressed by the design/development team at Westinghouse..... 1. The oil funnel provided is OK but hard to get the angle to the engine fill and oil can spill back out of the provided funnel because the angle is so flat. Why not put an oil fill tube for easier access/filling for a unit at this price point 2. The oil dipstick is difficult to pull and then even more difficult to insert back without a gap that allows leaks. The wire handle is flimsy and this could be so much easier with a better design. 3. The assembly for wheels requires flat washers as spacers between the plastic wheels and step on the axle shaft. However, there is NO space to fit the washers and get the clevis/cotter pins installed so I had to leave the washers off. Just a bad design on this item. 4. Connecting the battery is a pain. The positive was connected already but the ground was not. However, you have to lay on your side on the ground and try to fit your hands inside the frame and feel for the bolt hole to assemble the nut and tighten it down. There is no room for this unless one has lady hands. Moving the battery outward would allow better and easier access to connect the battery ground. Just a few items that I noticed. None are deal killers and some are one time tasks unless/when you have to change the battery. Overall I really like the unit and looking forward to testing on the house this next week. My expectations are high for a quality unit to have as a backup generator.

Works Great

I just received the generator and went together flawlessly!! Hooked up to propane cylinder and fired right up. I left it run for about 15 minutes and double checked oil. I fired it back up and started charging a cordless drill battery for about 30-40 minutes and worked perfectly. Still haven't put it through the paces yet since breaking is 5 hrs.

WGen14500TFc Tri-fuel

After learning about portable generators, my son, his father-in-law, and I all three independently settled on this model portable over other portables and over whole house. It was easy to get an electrician to put in the necessary, electrical plug, and the electrical panel and to get a plumber to ensure the right piping and flow of natural gas over to the location. This is bringing me great peace of mind as we enter hurricane season.

Versatile, well built, high quality generator

I bought this generator during the emergency preparedness tax free weekend. I had a Generac 6500 portable generator but needed higher output and the flexibility to run off of natural gas. This is a great generator with low THD that integrates perfectly into my home electrical system!

Just received and set up

We received red this generator about a week ago The assembly was straight forward with no difficulties. The unit fired right up on a 20lb propane tank. Only tested a drop light so far to confirm there is an output. The generator is loud but not near what I was expecting. We are getting larger tanks installed and will complete the break in at that time.

Great Generator!

Excellent specifications. Comes with a V-Twin engine. Also comes with propane hose with regulator as well as natural gas hose (mine was missing but they are sending out asap). Additional items include engine oil, battery charger, tool kit with spark plug wrench, and funnel.

Power house!

Purchased the WGen 12000/15000 DF and I'm so impressed. I had an electrician install a Reliance Controls PB50 (50amp) plug to my house. Used a 50amp power cord from generator to house. This generator ran 100% everything in my house. I ran the Central A/C, ceiling fans, all lights in and out the house. TV's, microwave, wife's blow dryer, oven, furnace no problem. Didn't even bog down. I feel as though this thing had more to give than what I threw at it. I live in a 1700sf home so I hope this review can help those who are considering this unit. I highly recommend.

THE ONLY GENERATOR YOU WILL EVER NEED

THE BEAST IS WHAT THIS IS. ALL 432 LB'S OF HER. AFTER ATTACHING THE WHEELS AND MANEUVERING THIS THING OFF THE CRATE, IT WAS AN EASY PROCESS TO GET THE BEAST READY FOR FUTURE POWER GRID FAILURES. BOLTED ON THE LIFT BAR, FILLED THE CRANKCASE WITH THE 1.6L OF SUPPLIED OIL, CONNECTED THE BATTERY TERMINALS, ADDED SOME GAS, PAIRED THE REMOTE START FOB. THE BEAST STARTED ON THE SECOND TRY AND RAN WELL. I WILL ADD AS I READ QUESTIONS/ANSWERS ONLINE ABOUT THIS UNIT, I SAW NEW OWNERS SAY THAT AN OIL FILTER WAS NOT DESIGNED ON THIS TWIN MOTOR. I FOUND THE FILTER LOCATED FORWARD FROM THE MUFFLER ON THAT SIDE, LOWER SECTION OF THE MOTOR AN OIL FILTER RESIDES. THIS GENERATOR WILL GIVE MY FAMILY A GOOD SENSE OF SECURITY WHEN THE NEXT HURRICANE HIT MY AREA OF FLORIDA.
