Micro-Controller Controlled Operations

Unlike traditional products, the system is operated smartly with a micro-controller and its software. These include

  • Battery charging
  • Discharging
  • System changeover
  • Various fault protections for LED lamp
  • Various fault protections for charger
  • Multiple LED indications

LED Indications

The infrared remote control makes battery change-over testing is easier with just a press on the controller. It also provide 5-steps of dimming control for normal AC operation.
