Micro-Controller Controlled Operations

The whole system is software controlled by a single chip micro-controller. These include battery charging, discharge discharging, system changeover, fault protections, LED indications and infrared remote control.

The improves system reliability and makes the system smarter for the whole operations.

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.
