About MPPT:

MPPT (Maximum Power Point Tracking) ensures photovoltaic modules consistently deliver peak power output despite varying sunlight intensity, maximizing solar energy utilization. Under normal conditions, it automatically adjusts charging current based on real-time solar irradiance, maintaining the solar panel's output at its maximum power point to optimize the product of output voltage and charging current (total power).

Product Application Range:

Suitable for 1W-100W solar panels operating at 9V-28V (9V, 12V, 18V, 24V) to charge batteries, NiCd, NiMH, and Li-ion batteries (battery packs). wind turbines, solar street lights, etc. Both input and output terminals utilize high-grade high-frequency low-impedance electrolytic capacitors (LOWESR) specifically designed for switching power supplies, ensuring effective filtering of output ripple and elimination of switching power supply glitches.

Charging Management Board Features:

1. Maximum Power Point Tracking (MPPT) for solar panels, delivering output current exceeding panel input. True ultra-high efficiency MPPT supports 8-28V solar panels up to 100W. (Recommended one module per solar panel; multiple modules can be paralleled to increase charging current).

2. Fully adjustable output voltage with CC-CW automatic control (supports single/multiple cells of lithium, lithium iron phosphate, or lead-acid batteries; high-power LEDs, etc.).

3. Comprehensive battery charge management.

4. PWM switching frequency: 300KHz.

5. Constant current charging set via external resistor (preset 5000mA/2000mA).

6. Trickle charging for deeply discharged batteries.

7. Dual charging status indicators: Red LED on during charge / Blue LED on when full / Red flashing with blue steady indicates no battery connected.

8. Low-power soft-start function using imported high-frequency dual MOSFETs with low on-resistance, 10A high-current dual diodes, high-efficiency flat-profile power inductor, constantan current sensing resistor, low-dropout reverse polarity protection. Reverse connection prevents operation, safeguarding the charger board from damage.

Debugging Method:

Step 1: Connect the solar panel without connecting the battery to be charged. If output voltage is present, proceed to Step 2. If no output, slowly turn the MPPT knob counterclockwise until output voltage appears.

Step 2: Turn the output voltage knob counterclockwise until the red and blue lights flash. Then coarsely adjust the output voltage to the full-charge cutoff voltage.

Step 3: Connect the discharged battery. Monitor the charging current with an ammeter in series at the output. Fine-tune the MPPT potentiometer until the charging current peaks.

Step 4: Connect a freshly charged battery. If the blue LED illuminates, increase the output voltage clockwise until the red LED activates. Then slowly decrease the output voltage counterclockwise until the blue LED just illuminates. Use a multimeter to verify the cutoff voltage is correct to prevent overcharging.

Method using a regulated power supply instead of solar:

Step 1: Set the regulated power supply to the solar MPPT voltage (e.g., 18V).

Step 2: Connect the regulated power supply to the input terminal without connecting the battery. If output voltage is present, turn the MPPT clockwise until output voltage disappears. Then slowly turn the MPPT counterclockwise until output voltage just appears.

Step 3: Turn the output voltage counterclockwise until the red and blue lights flash. Coarsely adjust the output voltage to the full-charge cutoff voltage.

Step 4: Connect a freshly charged battery. If the blue light illuminates, turn the output voltage clockwise until the red light illuminates. Then slowly turn the output voltage counterclockwise until the blue light just illuminates. Use a multimeter to verify the cutoff voltage is correct to prevent overcharging.

Important Notes:

For the first charge, pre-adjust the output voltage and closely monitor the battery voltage to prevent overcharging! Do not charge unprotected lithium batteries.
