The EB2000 and the Eb2400 are the Heart of the Yamaha inverter line. The motor is built to be a generator from the start. This is not just a motor attached to a generator like so many other companies produce. This allowed Yamaha to make the generator part of the flywheel of the motor. This eliminates a lot excess weight.
44 pounds is very light for a 2000 watt generator. Yamaha specifically designed this to be a very light easy to handle generator. Many 1000 watt and most 1500 watt generators will tip the scales at 60 to 70 pounds. This highlights just how light this generator is.
Another key feature of this Inverter Genertor is the ability to connect this generator in Paralell to another EB200is. The Connection cord is available in two options. One is around $100 and the other is around $260.
A Key feature of this generator also is the Yamaha National Network of dealers. This is huge when you want to order repair parts or get this generator serviced.
