The generator specs and looks are fine, but.... (Rating: 3.00)
Review : No where in Amazon's presentation of this item is the fact that you will need an "isolation switch," also called a "transfer switch" at some stores. This is a [$$] item that allows you to switch off the electric power line from your utility company while you are using the generator to feed power to your home. This protects utility workers from electrocution that could occur if you backfeed electricity into the power grid. It protects your home circuits and appliances from overload when the utility power comes back on. Neither Amazon nor Yamaha mentions the fact that the Yamaha generator requires a particular locking plug for the AC output, and does not provide the NEMA number that you have to match when buying the power cord taking power out of the Yamaha to your home's electrical supply input. Yamaha's manual is ridiculously inadequate about how to set up this device, though the details for maintenance and safety seem pretty thorough. But you have to be able to use it, and using it requires a frustrating process just to know what parts to buy. And then there's the cost of an electrician to install the isolation switch. No plug-'n-play here.
Durable, Efficient, and Economical Power Generator! (Rating: 5.00)
Review : When I started construction on a cabin in the woods of northern New hampshire, I wanted to be sure I had a reliable alternative source of eleectrical power both for the construction effort and for time later when the basic power would be unavailable, as in an ice storm or other power outage. I was pleased to find this state of the art model from Yamaha because it had both an enthralling list of desireable features and was within the budgetary figure I had in mind for the generator. That said, I have been thrilled with just how powerful, durable, reliable and economical it has been both to own and to use. Yamaha truly has created a super quiet, small, and light generator, the best of its kind. it is a 2800 watt generator that emplys inverter technology. It's well suited for equipment requiring a stable frequency and voltage. Voltage output stability very "clean", so it can power microcomputers or sophisticated electronics, a feature we appreciate as we can use it evenings to power a laptop. When power demand power is low, the generator runs at a low engine speed, then, as power demand increases, engine speed increases in a corresponding power curve. This Yahama inverter system meets my needs superbly, and I can highly recommend it. Enjoy!
A lightweight, heavyweight! (Rating: 5.00)
Review : When I opened the box and saw this little generator, I thought I was in trouble. But this 2800 watt Yamaha is the new inverter model. Not sure what that means, but it is very light weight but really puts out the juice. We ran 2 screwguns, 2 - 500 watt quartz lights and our radio and this Yamaha barely ran above idle. It weighs half of what our old junker weighs, runs 4 to 5 times longer on a gallon of gas and purrs quiet as a kitten. We have been using this wonderful generator for over a year with no problems at all. It's Yamaha inverter generators for our crews from now on.
