What is MPPT solar controller?
MPPT solar controller is designed for solar power system design; Equipment can not only efficiently transfer issued by the solar panels to recharge the battery power, but also provides a powerful control functions.
Features: The controller is characterized by intelligent adjustment of the operating voltage solar panels, solar panel always working at the VA characteristic curve of the maximum power point. More common, solar controller, solar panels for power generation increased utilization of 10-30%!
The controller uses solar panels for intelligent charging of the battery. In the solar panel power than the battery storage capacity, the control system automatically cut off the charge, thus ensuring optimum battery charging features, making full use of electricity.
As the battery can only withstand a certain degree of charge current and float voltage, over current and over-voltage charging the battery will cause serious damage. The controller battery charge grams of real-time detection voltage and charging current, and by controlling the charge current to limit the photovoltaic battery charging voltage and charging current to ensure that both the battery is full, it will not be damaged. To increase of the battery service life.

Protection Functions
- Waterproofing protection
- Rating: IP32
- power limited protection
- When the power of solar panel is higher than the rated value, the controller will limit the power of solar panel within the rated power range to prevent damage by over current, and the controller enter the current-limiting charge.
- reverse polarity protection
- If the battery polarity is reversed, the system will not work but it will not burn out the controller.
- input end voltage is too high
- If the voltage at the PV array input end is too high, the controller will automatically shut off the PV input.
- input end short circuit protection
- If the voltage at the PV array input end is short circuited, the controller will turn off charging; after short circuit is removed, charging will automatically recover.
- input reverse polarity protection
- When the polarity of PV array is reversed, the controller will not be damaged, and normal operation will continue after wiring error is corrected.
- reverse charging protection
- Prevent battery discharge through the solar panel at night.
- lightning protection
- protection
- When temperature of the controller exceeds the set value, it will reduce charging power or stop charging.
