WS-ALMPPT30 Solar Light Controller
PWM SOC overcharge overload undervoltage short circuit protection
WS-ALMPPT series solar street light controller, compared with ordinary solar street light controller, the MPPT solar street light controller can increase the efficiency of PV modules by 10%-30%. It will start head lamp at dark, and the weak light will be changed into a strong one after 30seconds, and the light will be weaker on dawn in the fixed time. And the duration of strong light can be fixed. The strong light can be fixed as full power light + half power light in 10 to 12hours.
