Upon receipt of the generator, the only thing you need to do is add engine oil and fill and install the battery. The battery proved to be rather tricky to get in but it IS possible even when it seems like it just won't go in.
Things that are great: super quiet, easy to start, nice front panel connections
Things that would be nice: 1) quick-open/close front and rear access panels - screwdriver is currently required to check oil and drain fuel from carburetor. 2) recoil starter for backup - I have never had an issue, but when you need backup power the last thing you want to do is deal with jump-starting a generator. 3) swiveling wheels - it weighs 200lbs and you need to lift and move each side when you want to go any direction other than straight. 4) How about adding an oil filter or even a magnet on the drain plug? All engines create metallic particles as they wear; I would have a warm and fuzzy feeling if I knew I could change a filter to keep my engine happy (okay, to keep me happy).
Now for the good stuff: Powering on the generator is like starting your car. I always drain the fuel from the carburetor after I run the engine so it takes a bit longer, maybe 5 to 7 seconds of cranking, before it comes to life. This is actually good so the engine parts can become lubricated at slow speeds BEFORE the engine starts. I start on the "normal" (non-economy) and run for a couple of minutes before I start adding load to the generator. I backfeed my panel (I know how to do this safely!) and always turn the main power and all breakers off before I connect the generator. I then LEAVE the main power off and open the generator-feed circuit breaker which is 220V/30amp. I then turn on all of my circuit breakers slowly, one at a time, EXCEPT the A/C compressor and evaporator breakers.
I can run everything I need: powered-vent gas water heater, gas powered-vent furnace, four circulator pumps, 4 cu ft chest freezer, 9 cu ft chest freezer, 2 kitchen refrigerator/freezers, house lights (a normal amount), numerous wall-warts that stay plugged into the wall.... Running the above at the same time puts anywhere from a 20 to 30% load on the generator.
I can also run (not all simultaneously, but it makes for a very comfortable time off the grid): lights, garage door openers, garbage disposal, dishwasher, washing machine, dryer (gas-fired), two televisions, toaster oven, 1500W bathroom heater fan...pretty much everything I want to EXCEPT the A/C. Now, you need to be smart about how you use power. Don't start the dishwasher, run the garbage disposal and open both garage doors...just think about what else is running before you turn something else on. The power meter on the generator is useful for determining how much power you actually use at a given time.
I can ALSO run my electric oven with some limitations. I make sure no major appliance (dishwasher, laundry) is being used and turn off the refrigeration circuit breakers. Using the oven, a few lights, and one TV put an 80% load on the generator.
Now, in order to get the maximum efficiency out of this generator (any inverter generator, really), it needs to run on the slower, variable throttle "economy" mode. I would only do this when not running the major appliances. Fuel burn is hard to say because I have never run all "economy" or all "normal" for one tank of fuel. I will say that with my power usage (as described above) I go through about 4 gallons every 10 to 12 hours. It keeps my wife happy...which keeps me happy.
Also, if you have some CFL bulbs, you may notice flickering when on the "economy" setting and when a refrigerator compressor turns on. There is a slight delay (maybe one second) until the engine speeds up to deliver the required power. I only noticed this a few times over the 49 hours I was using the generator with Sandy. It could also be due to cheap CFL bulbs.
Periodic Maintenance: Besides oil changes after the first 10 and then every 50 hours, I start it every two months and let it run for 15-30 minutes. I use Sta-Bil fuel conditioner when I know I will not be going through a tank of gas within a few days (two years in a row!). When I am done with using the generator, I turn the fuel valve off and let it run itself out of gas. When you remove the front panel to drain the carburetor, you can inspect inside and vacuum out any debris like spiderwebs that end up in the cozy space.
Conclusion: I remain highly satisfied with my purchase. With a little bit of care and understanding, this generator should last a long time. I also did not want to spend more than twice the price of this generator on a whole-house generator that I can't take with me or let another family member or friend use.
and LASTLY, if you are going to use any generator, make sure you have at least one working Carbon Monoxide detector in the house.
I picked this inverter generator because my old generator had varying voltage. The lights in my house used to dim up and down. I wanted something that gave good quality power. I felt I had pushed my luck long enough and had not burned out any appliances or my well pump.
I used this genset the other day for 12 hours when the power got knocked out. It worked excellent and it is very, very, quiet. I could not hear it in my bedroom (unlike my old contractor genset). The eco setting work very well. The genset only burned 3 gallons of gas in 12 hours.
I like the fact that this generator can easily run for over 12 hours on one tank. I can fill the genset when I leave the house for work and it's still running when I get home. I don't have to worry about anyone in my family filling it with gas.
This genset is really well built It is quiet and efficient. You get what you pay for. I highly reccommend it.
I will focus on the maintenance aspect, which is very important. This generator was not designed with maintenance convenience in mind and you will struggle with it. Based upon the poor design for maintenance purposes, I will probably try a Honda if this needs to be replaced.
- The front and back covers are difficult to reinstall after removing them and the screws used for installation may be easily lost if you allow the cover to pop off once released. A latching mechanism would have been better. Both covers must be removed for full servicing.
- Oil change: get a funnel with a flexible nozzle, the oil has to go in almost horizontally. When draining the oil, a hole is provided in the bottom. Unfortunately, at first, the oil gushes beyond the hole and into the housing.
- Spark plug: a standard ratchet set won't be able to get into this tight fit. Yamaha provides a special toll (because the location is so poorly placed) to remove it. It is not a reliable way to ensure correct tightness.
- Battery: if you think all of the above is hard, wait until you try to access the battery.
All in all, the nightmare of servicing this will cause many users to just ignore it, but it really must be done to ensure proper operation when needed.
UPDATE: couldn't take the extremely poor design of the wheels anymore (it's almost impossible to move this thing around). Bought, on Amazon, the Sparco Folding Platform Truck, 660 lbs., 24-3/4 x 36 x 29-1/2 Inches. The generator fits, perfectly, on this platform. The generator now can be moved around with ease.
