I live off grid in rural Alaska, with battery bank, 4000 W inverter, and solar backup in a 24 V system. I use  a generator to recharge batteries when there is no sun. Have used Coleman, Generac, and Honda generators. Honda is top dog hands down. Going on 5 years and several thousand hours and virtually no problems.  Once in a great while the choke will stick due to poor design and at that time it will have to set for hour or two before restart. Has only happened a few times and is not an issue in normal temps. Can be a problem at below zero temps. Honda has probably elinated the problem in newer models. I recommend spending the extra money...get the Honda.

i have owned this generator for about 5 years, besides replacing the battery once ( no big deal)  and doing scheduled scheduled maintnenace its been great. You pay more but the features are well worth it particularly because nowadays all your appliances have are electronic. Cheaper generators are loud and can fry your electronic boards, which are more expensive to replace them then the appliance itself in some cases. Why spend $$$ on high end appliances and short sheet yourself on a generator if you dont have to. I live in the rural north east have a well, oil fired furnace etc. I hooked up a sub panel with atransfer switch and can power the furnace, sump pump, well, refridgerator and one gp circuit. I like the fact that it throttles back when not in peak demand. Prior to this generator i had an off brand that burnt out after 3 days during a snow storm. Honda engineering is worth the peace of mind.

I have owned this generator for some 13 years. Purchased after Hurricane Charley. It's wired to the main disconnect of the house thru a transfer switch. Awsum unit. I power the (4550 watt hot water heater only), for a 20 min reclaim. Then the Fridge, Window A/C, TV and lights. 5 gallons of gas lasts around 12 hours. I shut it down at night to give it a rest as we do not require it to be run while we sleep. I change the oil every 4 tanks, (48hrs run time) and every July, if not used during the year. Drain the gas and run it with 10oz of WD 40 till it stops. The next time it's needed, fill the tank and 1 pull, it starts. The Air filter did need to be replaced due to age, just reg maintenance. Still looks new.

Thanks Honda for an excellent machine.

I have had this generator for15 years and even though I don't use it for prolonged periods of time, it starts 1st pull EVERY TIME. It is somewhat economical on fuel and I built an entire home with it as well as its a great pal when hunting. Only draw back I can see is the weight,, too heavy for one old man lol.

This generator is everything I expected from Honda. I had several technical questions about this generator and Honda's customer service tech was very informative on all of my questions. (try talking to some of the competitors customer service). I did a load test on the generator and the voltage did not fluctuate at all. I have  not had this generator long enough to comment on the long haul, but because it's a Honda and a good reputation I'm confidant it will last for a long time. Try to purchase from a dealer versus a box store, I think you will get better service should you need it.

Picked up this generator and two days later had our power go out from a big snow storm. Worked flawlessly until our power came on 3 days later. One filling, it lasted 18 hrs., but we only had the frig, well pump and some lights hooked up. Still need to install a house plug-in and a transfer switch, etc. to power minimal items for when the next outage occurs. This is not a whole house generator so expect it to only power essential items up to its rated circuits. Changed oil at 18 hrs. and went with synthetic oil.

I've lost track of how many hours and times my EM 5000S has provided trouble free home back up power during hurricanes, tropical storms and plain ole Noreasters over the last 12 or so years when the power goes out. (Not to even mention the countless uses powering my motocross trailer/camp trailer up and down the eastern seaboard). My long history and experience with this unit was completely different than the previous review so I thought it would be noteworthy to mention that I've had zero issues or glitches with it's operation over the past decade. Now I bought mine brand new and have been the only owner.

Most recently, during hurricane Matthew, the generator was used non stop for approx 26 hours supporting my immediate family and 6 St. Augustine evacuees to include one from an assisted living facility that was required to evacuate. During power outages, I power everything in a 3000 sq ft home except for the central HVAC, water heater and washer & dryer. The refrigerator, deep freeze, all lights, fans, TV, microwave, etc is used as if the normal power is operational. When applicable, I run a portable AC unit as well. When taking in evacuees that require the use of electrical medical devices, it's imperative to be able to depend on the generator and this bad boy has been flawless. 

There's very little maintanence required on this unit but I keep the unit spotless, gas is always drained from the carburetor when not in use, and the oil is changed when necessary. If I've not had to use the generator for a period of time due to a specific outage, I'll start it up and run it for a few minutes once a year or so. I've seen friend's cheap generators advertising similar wattage come and go over time so I think it is important to remember that all generators are NOT created equally. Yes, it's way more expensive than one you might see at a big box retailer, but when the power is out during a CAT 3 blow and family & friends are scared and panicking in the dark, everyone is quickly relieved when all the modern conveniences become available again via generator. The downside of having a Honda generator is that friends and neighbors remember that you have one and they make your house their evacuation location. (I joke re: "downside").

Literally the only thing that prevents it from still being in showroom condition is a small plastic piece that cracked that goes on the DC negative terminal. This in no way effects the usability of the unit and is hardly worth mentioning so I only do so for 100% complete disclosure of my experience. I suspect that I could replace this small plastic piece for a couple bucks if I get around to it. In the end, I've been overly pleased with this model due to its ease of use and dependability.. If properly cared for, the superb fit and finish will present as if it's brand new for at least a decade in my case..

I bought this unit several years ago to run the necessities (refrigerator, freezer, etc.) during power outages. The first couple of times it ran good. The third time it ran for about 4 hours and ran out of gas. I let it cool off, refueled and started it back up. Before I could plug it in a thick cloud of smoke appeared so I immediately turned it off. I took it to the dealer and told him the unit had only ~16 HOURS on it. He said it looked brand new (garage kept with a cover). He worked on it and said it was either the windings had burned up or the exciter. He said it would cost ~ $1500- $1800. I asked if he could work with me because again it on had about 16 HOURS on it. He said he would talk to the Honda rep. The rep said it did look brand new but there was nothing he could do.

So I spent 2500 DOLLARS on a piece of junk that won't work. I don't have $2500 to throw away.

Just the repair cost is THREE times the cost of generators my neighbors have that are still working. They have used theirs in the same manner that I did.

I need to buy a new generator, a new lawn mower, a new outboard motor (115-150 HP), and a new SUV.

Do you think I will be looking at Hondas... NO WAY!!!

If Honda decides to work with me then I will update this review.

We bought our generator in August 2011 for a hurricane that knocked out power to most of Connecticut.  We used it for 7 or 8 days.  Then at Haloween 2011 we had a major Nor'Easter and were without power for 9 days.  Last night I got it out to make sure it would start okay for the Nor'easter coming tomorrow (1/27/15) and it fired right up.  I hadn't started it since October 2014.  The battery is amazing as it always is right up to power.  We run everything in our house except the clothees dryer, the oven (we have a gas range and electric oven) and A/C.  We have a well so when the pump comes on you can hear the generator lug down for a few seconds and then it just hums away.  We run furnace, lights, TV, dishwasher, Microwave (my wife baked a cake in it), she irons, we use hair dryers and most of the things oncurrently. 

This is the best piece of equipment I have ever owned.  During the storms it would run nonstop form about 7 AM until almost midnight.  It would use about 7-8 gallons of gas a day.

I bought this generator last spring. It sat idle for about 8 months before we lost power over the weekend.  The electronic start didn't work, but it started up first pull with the backup recoil.  Looking back, unless you're planning on using this on a regular basis, there's no reason to opt for the electric start.  Other than that, so far so good. It kept us up and running for 72 hours until power was restored. Ran through about 10 gallons/day.

We replaced our Generac 5500w generator with this Honda EM5000SX. Although Honda does make quieter Generators than this model (for about twice the cost), this one is rather quiet. Especailly compared to our old Generac (you can talk while standing over it with a raised voice, not shouting). We just recently had a 48 hour power outage. We powered some basics; refrigerator, deep freezer, about 4 fans, couple lights, television, occasional use of coffee pot and microwave. Also had our neighbor plugged in they had a refrigerator, television, a few fans, light or two. Also used an electric power washer with during the outage. We used about 2 1/2 tanks of fuel (about 18 gallons). The auto throttle seems to help conserve fuel and trips to the gas station. With our old generac in these conditions I would say we would have used probably about 25 or so gallons. So far we are pleased with it.

The dealer (Wayne at Hammond Tractor Union ME) was quick courteous and had the unit together and even filled with gas. He gave me a quick but complete overview of operation and proper use and then helped load the unit. They did not rush even though it was Christmas Eve and it was in the aftermath of a major Ice storm. Works perfectly and we have no complaints so far. We recommend the unit highly.
