lighting  controller WS- AL MPPT30 30A 25A 20A


Category :Solar charging controller for lamps

Model : WS-AL MPPT30

WS- AL MPPT30 30A 25A 20AWELLSEE solar charge lighting controller is controlled by micro-CPU,which can intelligently regulate the working voltage of solar panels, making the solar panels always work at Maximum Power Point of V-A curve. Compared with ordinary solar street light controller, this MPPT solar street light controller can increase the efficiency of PV modules by 30%. It will start head lamp at dark, and the weak light will be change into a strong one after 30 minutes, and the light will weaker or dawn in fixed time . And the duration of strong light can be fixed.The strong light can be fixed as full powerlight + half power light in 10 hours,For example,You can set up the strong light for 6 hours(full power light), 4 hours weaker light(half power light),then change into morning light and the controller out-off of supply to the load automatically until dawn.


WS- AL MPPT30 30A 25A 20AWELLSEE solar charge lighting  controller could also be in charge of batteries’ charging as well as discharging. It will protect batteries by cutting off head lamp’s work automatically if the batteries’ voltage is low, and coming into the condition of float-charge controlled by PWM automatically if the batteries are filled with electricity. It will cut off charging circuit in order to protect batteries from discharging through solar panel at dark. Moreover, the controller also has a perfect protection circuit to prevent itself from being damaged accidently. Making the entire system can be in efficient and safe operation.


WS- AL MPPT30 30A 25A 20A WELLSEE solar charge lighting  controller choose the most advanced power device, the compact and concise LED display, operation conditions of the system is easy for can be used in the harsh physical environment like cold,hot and moist.
