Subaru combines state-of-the-art inverter technology with extreme durability. They are ideal for applications where low noise and high-quality, stable voltage are musts. These units quietly work hard, powering anything from sensitive electronics to jobsite tools, and in applications as varied as construction in populated neighborhoods, recreational camping and standby emergency power. Resin panels with sound-absorbing foam lining dampen noise. The automatic power system adjusts engine speed to meet power requirements and reduce noise while increasing fuel efficiency and engine life. The muffler design provides optimum sound reduction. Easy key start with recoil start as back up.
