DC off-grid systems

Many of the solar off-grid products in the markets are 2 bulb home system, 3 bulb and fan system etc. All these products runs with battery in non sunshine hours. The PCB developed for this type of application have charge controller only. Also the PCB have battery level indication for understanding battery energy.

The PCB can be used in home system applications with the following specifications

  • Solar Power – 50Wp – 150Wp
  • Loads – Bulb, Fan, TV, USB charging etc. (15W – 60W)
  • Battery – 12.8V/11.1V/12V, 6000 – 60000mAh
