BQ24650 MPPT Solar Controller Lithium Battery Lead Acid Charging Street Light Buck Module Adjustable

 
Description:
  • Features:

    Module function introduction

    *Application Used for solar panels to charge lithium batteries (or acid lead batteries), support mppt algorithm.

    Suitable battery type

    Li-Ion, Li-Polymer, LiFePO4, PbA, NiMH, NiCd


    Charging Current : 2A 4A 8A 10A



    Charging mode : Multi-cycle Self-charged discharge

    Output adjustable 2.1v-26v


    Unpacking test method (using digital power for input source test)

    step 1.

    1.1 Connect the input power (5~28V):

    The digital power output needs to be set to the MPPT voltage value of the photovoltaic panel;



    1.2 adjust the MPPT potentiometer,

    a) To enable MPPt, make the voltage of the MPPTSET point of the chip 1.2V;

    b) To turn off the MPPT, make the voltage of the MPPTSET point of the chip lower than 75mV;

    Step 2.

    The no-load regulation output Vout potentiometer is lower than the input voltage;

    Step 3.

    Connect the load, connect the photovoltaic panel, do the charging test

    a) If you need to observe the charging current, please observe the current file of the multimeter in the positive terminal of the output terminal;

    b) If the charging voltage is observed, please connect the multimeters voltage file at the output end for observation;

    1.1 Connect to the input photovoltaic panel (5~28V):

    Step 2.

    The no-load regulation output Vout potentiometer is lower than the input voltage;

    Step 3.

    Connect the load, connect the photovoltaic panel, do the charging test

    3.1

    a) If you need to observe the charging current, please observe the current file of the multimeter in the positive terminal of the output terminal;

    b) If the charging voltage is observed, please connect the multimeters voltage file at the output end for observation;

    3.2 Adjust the MPPT potentiometer,

    3.3 Observe the current value of the current meter of the multimeter and take the stable electrical value. The phenomenon of the charging lamp is the maximum current value of the constant light (stable charging state). (When the input power is insufficient, it will flash, and if it is not, it means no charging, it is a flashing and charging).

    a) To enable the current PV panel MPPt, make the MPPTSET point voltage of the chip 1.2V. The premise is that the output power is larger than the current PV panel power, otherwise the PV panel will not reach the maximum power state;







    *3. Note that this method calibrates the MPPT potentiometer to have a relationship with the weather. Sometimes the MPPT value is not adjusted. In batch mode, the method of directly setting the resistance value is the most reliable.





    **Remarks

    a) One-turn potentiometer is a wearing part, and the two ends are blocked. It is easy to damage if the force is too strong. It is recommended to change the chip resistor after testing the result. There is a description at the back of the page.

    b) The page has an NTC line to add instructions, please seal the shell user to pay attention

    c) Regarding the charging and stopping cycle, the default is enabled. The user can also comment off, and turn off the cycle to charge more. This section is different depending on the scene, please also decide by the user.

    The manual description is as follows

    Charge termination enable. Pull TERM_EN to GND to disable charge termination. Pull TERM_EN to
    VREF to allow charge termination. TERM_EN must be terminated and cannot be left floating.
