The EF2000is is a single phase silent inverter generator which provides high-quality electricity suitable for sensitive electronic equipment. The EF2000is has light recoil starting as well as DC output capabilities for easy battery charging. This model also features an economy control system to regulate RPM according to load as well as very silent operation.
The EF2000is can also be run in parallel with another EF2000is and coupled together with a Yamaha Twin Cable ( optional Accessory) to develop an additional 2 kVA and total output would be with a Max rated output of 4 kVA
