Specifications

 WS-AL MPPT30 20A  48V  WELLSEE choose the most advanced power device,the 

compact and concise LED display, operation conditions of the system is easy for checking.it can be used in the harsh 

physical environment like cold,hot and moist.it is superior in property,high quality,and With 12V series, 24V series and 

48V series., the products can meet the requirements of different users. It Is an multifunction and multipurpose

which is exclusively used in solar street light or solar power system households.

 

Functions and features

 

1, MPPT function

2, Microprocessor 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 LED 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 isnt output and the load cannot work.

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

  

Configuration:

 

       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 : youd better choose the wire which is connected the solar panel and WELLSEEaccording to 1A/m.

 

Superior MPPT:

 

       Maximum Power Point Tracking(MPPT) is an electrical system which is adjusting 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  making the 

system working at 12V, only output at wer points of 53W,B means the MPPT  can make the photovoltaic cell always 

working at the Maximum Power Point, and output up to the wer points of 75W.
