Silent Series generators offer reduced sound, engine speed

The Robin Subaru Silent Series generators feature advanced inverter generator technology that significantly reduces running sound. The generators, which come in three models — the R1700i, the RG3200iS and the RG4300iS — also run the engine at a lower speed for low power use and automatically increase speed as more electrical power is required. Designers achieved further sound reduction through the reverse cooling design, which allows the generators to be fully enclosed in sound-absorbing poly-resin.
