WS- AL MPPT60 WELLSEE led controller for street light

This new WELLSEEE led controller WS-AL MPPT60 controlled solar lighting charge controller will eliminate the need for seperate charge controller, timer ,light-dimmer and light control in a 12/24v, and 48V lighting system. It uses the photovoltaic array to detect day and night and will learn the length of your night in order to provide light before sunrise. Save battery and array size by setting the light to turn off in the middle of the night.

MPPT explaination

Maximum power point tracking is a technique that solar inverters use to get the most possible power from the PV array. Any given PV module or string of modules will have a maximum power point: essentially, this defines current that the inverter should draw from the PV in order to get the most possible power (power is equal to voltage times current).

Configuration and Notice:

 Solar panel: the system of 12v should choose the 40 pieces connected in series, the voltage of Maximum Power Point should be above 18V, the 24V system shoule be choose the two piece of the solar panel which is above-mentioned. The wire : you’d better choose the wire which is connected the solar panel and WELLSEE controller according to 1A/m 

2.Functions and features

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, 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: load). When it is bright, there is output and load can work; if LED goes out, means there isn’t output and the load cannot work.

l   Battery indicator: red =under voltage   Green =full    Yellow =normal
