Has anyone had an issue with their remote? I'm on my 5th set of batteries since March 1,2018. Was getting 5 months from the batteries initially, but in the past 6 months, 4-6 weeks is all I'm getting. Would like a call from the home office!

Too see what's going on, your best resource for that level of support would be to contact a local service center. You can find one in your area by clicking here: http://bit.ly/2f9fanP

Rated 5 out of 5 by from Full home power We purchased this over the winter. We have enjoyed the peace and comfort that it affords. It runs each Sunday morning to remind us that it is ready to run when needed. [This review was collected as part of a promotion.]

Rated 5 out of 5 by from Update, everything is OK now. Service is great from my dealer. First thing I want to say is, Don't DIY, GET A LICENSED ELECTRICIAN! I had 2 journeymen and 2 Electrician's in training, that makes four to pick up this heavy monster. The Generic is lighter and smaller size. The Generac battery is very hard to install inside the unit compared to the Briggs. After they got in out of the trailer two men stayed and the other two finished the job. It took 4.5 hours and they do this for a living. The Briggs runs smooth and very quite its putting out a very strong 20KW because we used propane, natural gas is OK, but if we have an earth quake "which we are going to have the question is when" and it breaks the natural gas lines 30 miles away or breaks it up in many places, it may take a while to get it back on so we went with the propane because of that and it develops more power for your home. We lose power about 6 times a year, but 3 times now it was off for more than a week. We also have a lot of tornadoes and high winds too and the power goes off when they hit a power station. I have a Generac for sale if that tells you anything, I know you can get a bad apple once in awhile but I didn't want another one.

Rated 4 out of 5 by from Biggest issue is with the starters failing We sell primarily Briggs Fortress units. In the last couple of years we have had countless engine starter failures. The Wo Long 12v 171018 model is the problem. We can’t keep enough of them on the service vans. This is the weak link to a very good product. The frustration comes from having to replace these starters with the exact same product and knowing that the new one won’t last either. Please replace this product with a more dependable part. We have game as far as taking them apart and locating the defect, reported it to technical support and our rep and nothing is changing. Briggs is getting a black eye over this problem. As I write this, one of my Technians is changing another one. Your only as strong as your weakest link. Please take this report seriously.
