Subaru’s conventional generators, the RGX3000 and RGX3800, are designed to handle the needs of contractors, homeowners, and recreational users. The RGX3000 is powered by Subaru’s 6-horsepower EX17 engine. The unit delivers a maximum output of 3,000 watts (2,400-watt standard output rating) and offers 10.3 hours of continuous operation. Powered by the 7-horsepower EX21 engine, the RGX3800 delivers a maximum output of 3,800 watts (2,900-watt standard output rating) and can operate continuously for 9.5 hours. Also, the RGX3800 features an automatic idle control, which lowers the engine speed when no electrical power is needed. This further lessens fuel consumption while minimizing noise.
