Prostar 12v 24v 20 amp mppt solar charge controller

Prostar 12V 24V MPPT solar charge controller is an advanced maximum power point tracking (MPPT) battery charger for off-grid photovoltaic (PV) systems up to 1.3kW.

Prostar MPPT solar charge controller 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.

  Product 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.


  • Equipped with 5V3A USB dual output power supply function, support mobile phone and tablet charging products etc.
  • 4-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 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.


  • Three kinds of commonly used lead-acid battery (Seal\Gel\Flooded) parameter settings fcan be selected by the user, and the user can also customize the parameters for other battery charging.
  • Automatically detects 12V / 24V 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 .
