The solar street light controller is suitable for solar control power supply systems, especially for independent solar street light systems. The controller can extract and store solar energy to the maximum extent possible. It includes the following control functions: 1 Provide maximum power tracking channel for solar energy input (independent control) 1 Road 2 Provide optical control output channels (time-division multiplexing ports). Route 1 3 Provide time controlled output channels (time-division multiplexing ports). 1 Road 4 Reverse connection of solar input channel, reverse charging protection. 5. Output channel current limiting and short circuit protection (including light controlled output and time controlled output). 6. Battery input reverse connection protection (continuous reverse connection without damage). 7. Supports 24V and 12V solar input street light systems, with internal automatic recognition and control.
