Prostar SunStar 40a 12v 24v 36v 48v mppt solar charge controller 150v is an advanced maximum power point tracking (MPPT) battery charger for off-grid photovoltaic (PV) systems.

SunStar 40a 12v 24v 36v 48v mppt solar charge controller adopts DC/DC converting technology and MCU technology. It can adjust the working point of the solar array intelligently to make the solar array realize the maximum power output.

SunStar 40a 12v 24v 36v 48v mppt solar charge controller 150V PV input will measure the Vmp voltage of the panel, and down-converts the PV voltage to the battery voltage. Because power into the charge controller equals power out of the charge controller, when the voltage is dropped to match the battery bank, the current is raised, so you are using more of the available power from the panel.

MPPT Solar Charge Controller Features & Benefits


  • Advanced maximum power point tracking technology with high tracking efficiency up to 99%.
  • Multiphase synchronous rectification technology ensuring peak conversion efficiency up to 98%.
  • CE, RoHS compliant approved, we can assist clients to pass various certifications.


  • Reverse polarity protection.
  • Electronic protection against overcharging, over-discharging, overload, and short circuit.
  • It has a current limiting charging function. When the power of PV is too large, the controller automatically keeps the charging power, and the charging current will not exceed the rated value.


  • 3-stage battery charging process for a rapid, efficient, and safe battery charging.
  • The use of high strength plastic shell design makes the shape beautiful, and the effective reduction of the product weight can save the transportation cost.
  • High definition LCD display function to check the device running data and working status, also can support modify the controller display parameter.
  • RS485 & RJ45 communication, we can offer communication protocol to convenient user’s integrated management and secondary development.
  • Support PC software monitoring and WiFi module to realize APP cloud monitoring.

    WiFi App Communication Data Monitor for Prostar Solar Charge Controller


  • Three kinds of commonly used lead-acid battery (SealGelFlooded) parameter settings fcan be selected by the user, and the user can also customize the parameters for other battery charging.
  • Automatically detects 12V / 24V / 36V / 48V DC system voltages.
  • Natural cooling design is adopted to improve the reliability of the product and prolong the service life of the product.
  • Four types of load mode selection: ON/OFF, PV voltage control, Dual Time control, PV+Time control .
