    Maximum Power Point Tracking Solar Charge Controllers (MPPT) are different than the traditional PWM solar charge controllers in that they are more efficient and in many cases more feature rich. MPPT solar charge controllers allow your solar panels to operate at their optimum power output voltage, improving their performance by as much as 30%. Traditional solar charge controllers reduce the efficiency of one part of your system in order to make it work with another.


    Prostar SunSaver MPPT solar charge controller adopted with auto cool, high conversion efficiency, LCD display and free PC software. It features an efficient MPPT control algorithm to track the maximum power point of the PV array in any environment. Greatly improve the utilization of solar panel. Also added the output function(USB 5V 3A). For the mppt controller can be widely used in off-grid solar system, Communication base station solar system, household solar systems, street light solar systems, field monitoring and other fields.

    Features of Prostar Solar Charge Controller

    1.High efficiency MPPT control algorithm, MPPT efficiency ≥99.5%, whole Machine conversion efficiency upto 98%; 

    2.12V/24V system Automatic Recognition,users can use it in different system conveniently.

    3.Maximum PV input voltage: 100VDC(15A, 20A), 150VDC (30A, 40A,5 0A)

    4.Charge mode: three stages (fast charge, constant charge, floating charge). It prolongs service life of the batteries.

    5.Discharge mode: ON/OFF mode, PV voltage control mode.

    6.Recommended battery types: sealed lead acid, vented, gel, NiCd battery. Other types of the batteries can also be defined.

    7.Most information could be provided by LCD like: system type. PV input voltage, battery type, battery voltage, charging current, charging power, working status and so on. 

    8.RS232 communication, we can offer communication protocol also, it’s convenient for user’s integration management.

    9.CE, RoHS, FCC certifications approved.. We can help clients to approve other certifications.

    10.2 years warranty. And 3~10 years extended warranty service also can be provided.  

    You can get benefits as below:

    • You can apply more input on the controller than it's rated for. Output current will be limited to the max controller current rating. This allows you to get optimum usage of controller capacity.

    • The advanced electronic design offers long life and reliability. The 3 independently controlled high frequency MPPT stages, giving you up to 15-30% more power out of your solar array versus a PWM solar charge controller.

    • The connections have up to #2AWG power terminals which are extremely robust terminal connections for a controller of this size. This is very useful when the controller needs to be a long distance from the array.

    • It is highly recommended to add the optional RTS (Remote Temperature Sensor) as the reading will come directly from the battery. This allows for a more effective charging and monitoring of the batteries.
