 Function:

1. Always keep the battery on full voltage condition.
2. Prevent the battery from over-charging.
3. Prevent the battery from over-discharging.
4. Prevent the battery from reverse charging to solar panels during nights.
5. Reverse Polarity Protection for Battery
6. Reverse Polarity Protection for solar panels
7. When the current of the load exceeds the rated current of the controller, the controller will activate the protection mode and lock up.
8. When the load short circuited, the controller will activate the protection mode and lock up.
9. When the battery voltage is low, the controller will automatically cut off the load from the system.If the voltage of battery is back to normal and the load will restart working.
*0. Thunder protection
*1. According to the battery voltage grade,the controller can automatically set charge-off voltage, the load-off voltage, the load-restore voltage.(The parameter is default under *5? condition, locked by the CPU procedure,cannot adjust.)
*2. The controller will automatically compensate the temperature of the charging voltage according to the changes of ambient temperature.

 MPPT principle:

The maximum power point is mainly affected by the ambient temperature and the intensity of sunshine. The intensity of sunshine being constant, the maximum output power decreases with the rise of the temperature. The temperature being constant, when the sunshine intensifies, the open circuit voltage of PV battery basically keeps unchanged. But the short circuit current increases substantially, thus the maximum output power increases substantially.

This WS-MPPT solar controller can intelligently regulate the working voltage of solar panels, letting the solar panels always work at Maximum Power Point of V-A curve. Compared with ordinary solar controller, this MPPT controller can increase the efficiency of PV modules by about *0%.

However, due to many different factors, such as the difference in solar panel making, the change the Sun illuminance, change in temperature, the efficiency of the controller etc., the actually available increased rate is *0%**0%.
