Product Features

. PowerCatcher maximum power point tracking technology allows the controller to track the maximum power point of solar panels even in a complex environment. Compared with the traditional MPPT tracking technology, it boasts faster response speed and higher tracking efficiency.
. A built-in maximum power point tracking (MPPT) algorithm can significantly increase energy utilization efficiency of the photovoltaic system, which is about 15% to 20% higher than traditional PWM charging.   
. It provides an active charging voltage regulation feature. At battery open circuit or lithium battery BMS overcharge protection, the controller battery terminal will output the rated charging voltage value.
. MPPT tracking efficiency is up to 99.9%.
. Due to an advanced digital power technology, the circuit energy conversion efficiency is as high as 98%.
. Available in multiple battery types and support charging procedures of various types of batteries such as lithium battery, colloidal battery, sealed battery, vented battery, lithium battery, etc.
. A current-limited charging mode is available. When the power of solar panel is too large and the charging current is higher than the rated valve, the controller automatically reduces the charging power so that the solar panel can operate at the rated charging current.
. Support automatic identification of lead-acid battery voltage.
. External LCD screen or Bluetooth module can be connected for viewing of equipment operating data and status, and modification of controller parameters is supported.
. Support standard Modbus protocol to meet communication needs in different occasions.
. Built-in over-temperature protection mechanism ensures that when temperature exceeds the set value of the device, the charging current decreases linearly with the temperature, thereby reducing the temperature rise of controller and avoiding high temperature damage.
. Temperature compensation and automatic adjustment of charge and discharge parameters help to improve battery life.
. Solar panel short circuit protection, battery open circuit protection and TVS lightening protection etc.

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.

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.
