MPPT Laderegler 30A 12V/24V für Solarmodule
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 10%-30%
Maximum Power Point Tracking (MPPT in short) system is a system which allows PV panels to outputs more Power by adjusting working condition of the electrical module. In Figure1 A indicates that the ordinary controller, which makes PV battery work on 12V ,only outputs a power point of 53W (a general power point), B indicates that MPPT controller makes PV battery always work at the maximum power point, thus outputs the power point of 75W (the maximum power point)
Applicable to various types of batteries
· Temperature sensor battery charging compensation
· Overload protection (automatic restoration)
· Overcharge protection
· Short circuit protection (automatic restoration)
· Thunder protection
· Reverse discharge protection
· Reverse polarity connection protection (automatic restoration)
· Under voltage protection
· Always keep the battery on full voltage condition.
· Prevent the battery from over-charging.
· Prevent the battery from over-discharging.
· Prevent the battery from reverse charging to solar panels during nights.
· Reverse Polarity Protection for Battery
· Reverse Polarity Protection for Solar panels
· When the current of the load exceeds the rated current of the controller, the controller will activate the protection mode and lock up.
· When the load short circuited, the controller will activate the protection mode and lock up.
· 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.
· Thunder protection
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 25°C condition, locked by the CPU procedure, cannot adjust).
The controller will automatically compensate the temperature of the charging voltage according to the changes of ambient temperature.

Take an example of connection between solar panel board, rechargeable battery and a light bulb with the MPPT 30A Solar charge controller.
· Firstly, connect the solar panel board to the MPPT 30A Solar Charge Controller for power input.
· Secondly, connect the rechargeable battery to the charge controller.
· Hence, plug the light to the rechargeable battery. The light bulb then can be turned on
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 30%.
However, due to many different factors, such as the difference in solar panel making, the change the Sun luminance, change in temperature, the efficiency of the controller etc., the actually available increased rate is 10%-30%.
