Description:
The Solar Charge And Discharge Controller model BR4860 is designed for off-grid photovoltaic systems. It uses advanced maximum power point tracking (MPPT) technology to maximize energy harvest from solar panels. The controller automatically adjusts charging current and voltage to suit the connected battery bank. It supports system voltages of 12V, 24V, 36V, and 48V with automatic detection. The unit provides a rated charging current of 60A and a rated load current of 20A. It includes multiple charging programs for gel, sealed, and other battery types, along with limited current charging mode. The controller is suitable for solar base stations, remote monitoring systems, and other DC power applications.
