Models in the Subaru inverter generator line include the R1700i at 1,650 watts, the RG3200iS at 3,200 watts, and the RG4300iS at 4,300 watts. The advanced inverter technology significantly reduces running sound. Subaru inverter generators run the engine at a slower speed for low power use, and automatically increase speed as more electrical power is required. Further sound reduction is achieved through the reverse-cooling design. This allows the generators to be fully enclosed in a sound-absorbing poly-resin enclosure for near-silent operation.
- R1700i powered by Subaru's EH09-2 OHV gasoline engine
- RG3200iS and RG4300iS models powered by Subaru's EX OHC gasoline engines
- Voltage and frequency are electronically controlled to maintain accuracy through the full power range
