Solar Energy is a best alternative energy solution. The visible light from the SUN (Solar energy) can be converted into electric energy by Photovoltaic Cells. It has potential to cater the emerging needs of the power throughout the world. Solar Hybrid Inverters are cost effective and easy to install.

EAPRO True Hybrid Solar Home UPS is the most innovative and advance UPS that runs both on solar power (generated through solar panels) and the utility (grid) power supply. EAPRO True Hybrid Solar Home UPS is the advanced solar hybrid home UPS which charge the battery thru readily available solar energy/ Mains by using it’s artificial intelligence. It’s ISSRC logic use Solar Power for its maximize utilization to empower homes.

How EAPRO True Hybrid Solar Sine wave UPS is different from other Hybrid Solar UPS :

  • Intelligent Battery Charging and Load Sharing using High Performance Advance DSP based Pure Sine Wave Technology.
  • ISSRC Logic : Intelligent Solar Selection based on Real Clock Logic.
  • PWM/MPPT* Solar Charge Controller : Inbuilt fully regulated PWM/MPPT* (Maximum Power Point Tracking) Charge Controller to get optimum utilization of Solar Power.
  • Ability to provide rated Output Power directly from Solar Panels (if Solar Power is available) in addition to charges the battery simultaneously.
  • Intelligent battery charging from Solar and Mains by giving priority to Solar Power and only remain power consumes from Mains.
  • Ability to run the Output Load exclusively through Solar Power, saving Grid Power and your hard earned money.
  • Provides power from the battery upto 80% charging, when solar and grid power is available and battery is fully charged, resulting save money and save electricity.
  • Intelligent Thermal Management System : Programmed Inbuilt cooling fan which operates as needed with thermal protection to prevent undue loss of energy.
  • Provision to set ‘NO CHARGING of Battery from Mains’ (by pressing a button) for Charging through Solar Power Only resulting true power saving.
  • Wireless operational Mode (OPTIONAL)

Key Features

  • Operate on both Solar Power as well as Grid Power.
  • It is integrated with in-built fully regulated PWM/MPPT* Solar Charge Controller for max. Solar Power utilization.
