 The GUARDIAN Elite line of liquid-cooled generators utilizes industrial grade engines for dependable service. Sound attenuated weather protective enclosures protect generator from the elements. This makes GUARDIAN Elite a powerful yet quieter generator. Compact profiles make for an appealing installation.

Standard Features

    * Exclusive Whisper-Test™ feature operates generator at low RPM during the system's weekly exercise cycle and reduces sound output by up to 50%. This fifteen-minute cycle helps maintain top running condition.
    * Built-in timed trickle charger maintains battery at optimum performance level.
    * Automatic safety shutdowns protect engine and generator in event of low oil pressure, low oil level, low coolant level, high temperature, overspeed and/or overcrank.
    * Transfer switch options are available in 100 amp, 200 amp or 400 amp sizes
    * Industrial Liquid-cooled Engine
    * Heavy Duty Cooling Package
    * Battery Charge Alternator
    * High Energy Ignition Coil
    * R100 Digital Control Panel with LED Indicators
    * UL Listed in both the US and Canada


Switching
  The completely automatic Guardian transfer switch monitors incoming voltage from the utility line - around the clock.
  When utility power is interrupted, the automatic transfer switch immediately senses the problem and signals the generator to start.
   The automatic transfer switch then safely closes off the utility line and simultaneously opens a new power line from the generator.
   Within seconds, your Guardian generator system begins supplying electricity to the critical emergency circuits of your home or business. The transfer switch continues to monitor the utility line conditions.
   When the automatic transfer switch senses the utility line voltage has returned at a steady state, it re-transfers the electrical load back to the utility line and resumes monitoring for subsequent utility loss. The generator will continue to run for an engine cool-down period of several minutes while the entire system stands ready for the next power outage.
