SPECIFICATION
50set/carton

We are the super-scale research and development enterprise of solar charge and discharge controller, the supplier of WELLSEE solar controller, photovoltaic system equipment. WELLSEE have passed the ISO9001, CE and ROHS certifications. We can design and produce according to clients special request. Welcome to be our agents.
intelligent controller 15A WELLSEE dc to ac 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 10%-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 MPPT15 15A WELLSEE intelligent controller could also be in charge of batteries charging as well as discharging. It will protect batteries by cutting off head lamps 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.

Functions and features
1,MPPT function
2, Microprocessor controller pulse width modulation (PWM) charging
3, amount of light can be fixed.
4, Suitable for polytype battery.
5, Overcharge protection
6, Short circuit protection (automatic restoration)
7, Thunder protection
8,Thunder protection Reverse discharge protection
9, Reverse polarity connection protection
10, It can set up to 20 steps TM Timing Module or 10 steps segment mode.
11, It has a LET indicator of the working condition of charging and discharging:
l One piece of Charge Indicator LED (mark: Charge). When it is bright, the battery is charged strongly; flickeringly means floating charge, no light means stop charging.
l One piece of Load Indicator LED (mark: Light). When it is bright, there is output and load can work; if LED goes out, means there isnt output and the load cannot work.
l Battery indicator: red =under voltage Green =full Yellow =normal

superior MPPT
Maximum Power Point Tracking(MPPT) is an electrical system which is adjusting the the working condition of electrical modules,making the solar panel can ourput more electrical energy, the fist picture is showing the connection between the output power of photovoltaic cell(Pb) , output voltage(ub) and output current(ib), A means the normal controller making the system working at 12V, only output at wer points of 53W,B means the MPPT controller can make the photovoltaic cell always working at the Maximum Power Point, and output up to the wer points of 75W
