 An advanced Tata Motors ( TML ) or Volvo Eicher ( VECV) engine powers the Guardian Residential Gensets. Engine incorporates the latest technology, which translates to lower maintenance cost & environmental benefits. The specifically designed water cooled engine is light in weight, compact, has high torque and is low on vibration. This enhances fuel efficiency and longevity of the genset.


MeccAlte / Stamford alternator provides a robust electric generation. Rated for 1500 revs a minute, it generates single or three phase output that conforms to BS 5000/IS 4722 norms. Being brushless, there is a near zero maintenance need. The functionality is better due screen protection, self excitation and regulation through AVR.   

The high quality power is due to:

  •  + 1.0 % Voltage regulation (max.) in static conditions
  •  IP: 23 protection with insulation class H
  •  Permissible overload of 10% for one hour in 12 hours of operation
  • The generated power has less than 5% total harmonic distortion (THD) which is suitable for sensitive electronic equipments and micro-chip based appliances such as medical equipment, laptops and

    variable speed HVAC (seen more often in homes and offices nowadays). 

Control Panel:-

The Microprocessor / Microcontroller based automatic generator start and supervisory device is designed keeping in view ease of operation. The panel has 20 characters x 4 lines backlit LCD, 13 LEDs and 9

keys which provide easy user interface.  RMS measurement of all measured components within 1% accuracy of measured value indicates high quality of power generated. Back lit LCD display facilitates easy reading and parameter settings. The panel is fully operational up to 4V and can withstand a voltage dip up to zero volts for 1 sec. Additional facility for remote start/stop of the genset can be provided. The controller calculates and
displays a ‘service due’ indication for hassle free maintenance.
