Notice
1.Be sure to connect correctly the positive andnegative poles of the battery firstly , the load , and lastly solarpanel .Don’t reverse.
2.Please check the rated voltage of solar panels.batteries, and load before connecting, Make sure their ratedvoltage should be all 12V(or 24V, or 48V)
3.Pay more attention to “ ” and “-“ poles of solarpanels, batteries, controller and loads during the process ofconnection.
4.The rated current of solar panels and loads mustbe lower than the controller .
MPPTprinciple
The maximum power point is mainly affected by theambient temperature and the intensity of sunshine. The intensity ofsunshine being constant, the maximum output power decreases withthe rise of the temperature. The temperature being constant, whenthe sunshine intensifies, the open circuit voltage of PV batterybasically keeps unchanged. But the short circuit current increasessubstantially, thus the maximum output power increasessubstantially.
This WS-MPPT solar controller can intelligentlyregulate the working voltage of solar panels, letting the solarpanels always work at Maximum Power Point of V-A curve. Comparedwith ordinary solar controller, this MPPT controller can increasethe efficiency of PV modules by about 30%.
However, due to many different factors, such as thedifference in solar panel making, the change the Sun illuminance,change in temperature, the efficiency of the controller etc., theactually available increased rate is 10%-30%.
