What is the benefit of the 1800 RPM engine speed?

An industrial 1800 RPM engine operates at a lower speed, which results in less mechanical stress, a quieter sound profile, and a much longer lifespan.

How long can the extended steel tank run the generator?

The integrated extended steel tank is designed to provide significantly longer runtimes than standard tanks, making it ideal for multi-day grid outages.

Is diesel fuel more stable for long-term storage?

Yes, a diesel standby energy system is preferred for longevity because diesel fuel has a longer shelf life and higher energy density than gasoline.

Can I monitor the diesel fuel levels from my smartphone?

Absolutely, with integrated Mobile Link™ monitoring, you can track fuel levels and overall system health from anywhere in the world.
