850 VA 12 V

Product Description
  • It is integrated with in-built fully regulated MPPT Solar Charge Controller for max. Solar Power utilization.
  • It senses the availability of solar power, grid power and accordingly gives preference to charging thru solar power and switches to the grid power if the solar power is not available.
  • It is designed to give you maximum benefit from the solar energy and minimize your electricity bill drastically.
  • Highly efficient battery charging from the solar energy as a result you will get non-stop power, save money, save electricity and protect the environment.
  • Advanced DSP based technology for absolute and stable and 100% pure sine wave output.
  • Indications for Mains ON, UPS ON, Batt. Low, Charging/ Discharging, Over Load, Short Circuit, Thermal Trip, Solar available/ Not available and PV reverse on LCD Display.
  • User- friendly LCD for the display of mode of operation and all parameters.
  • Dual Mode of working : UPS and Normal
  • UPS Mode : Fast switching, Input operating range from 180V to 260V.
