Subaru inverter generators include the R1700i at 1,650 watts, the RG3200iS at 3,200 watts and the RG4300iS, a 4,300-watt invertor generator. Subaru inverter generators run the engine at a slower speed for low power use and automatically increase speed as more electric power is required. Further sound reduction is achieved through the advanced reverse cooling design. The R1700i is powered by a Subaru EH09-2 OHV gasoline engine, while the RG3200iS and RG4300iS models are powered by Subaru’s EX OHC overhead cam gasoline engines. Generator operation is streamlined through a microcomputer that monitors the temperature of the electronics and electrical conditions. robinamerica.com/generators.aspx
