A question about the solar street light controller
How the LED lights and string
Output power: boost constant current output, step-down constant current output. Ordinary switching mode output (without constant current function, the output voltage is consistent with the battery voltage).
Battery voltage and charge current. You use 120W battery board to ensure that the open circuit voltage in about 20V, can be used in the 12V system. And then full power charging current is less than 10A.
The solar controller selects three conditions, 1) the system voltage. Generally rated as 12V or 24V
