5. Kuweka na Kuunganisha
Before connecting the module, ensure all power sources are disconnected. Observe polarity carefully to prevent damage, although the module includes reverse connection protection.
5.1. Identifying Terminals
Figure 2: Input and Output Terminals. The blue terminal block has clearly labeled connections.
- VIN+ / GND: Input terminals for the solar panel (DC 8-28V). Connect the positive (+) lead of the solar panel to VIN+ and the negative (-) lead to GND.
- BAT+ / BAT-: Output terminals for the battery. Connect the positive (+) lead of the battery to BAT+ and the negative (-) lead to BAT-.
5.2. Utaratibu wa Kuunganisha
- Unganisha Betri: First, connect your battery (e.g., 6V, 12V, 8.4V, 12.6V, 16.8V lithium, etc.) to the BAT+ and BAT- terminals. Ensure correct polarity.
- Unganisha Paneli ya Jua: Next, connect your solar panel (1W-100W, 9V-28V) to the VIN+ and GND terminals. Ensure correct polarity.
- Initial Adjustment (Important):
- Pato Voltage Marekebisho: Before connecting the battery, you can adjust the output voltage using the potentiometer labeled V-ADJ (often blue, multi-turn). Turn the potentiometer clockwise to increase voltage, counter-clockwise to decrease. Adjust to the desired charging voltage for your battery type (e.g., 14.4V for a 12V lead-acid battery, 4.2V per cell for lithium-ion).
- MPPT Voltage Marekebisho: The potentiometer labeled U-MPPT (often blue, multi-turn) adjusts the Maximum Power Point Tracking voltage. With the solar panel connected and under maximum illumination, adjust this potentiometer to achieve the manufacturer's specified MPPT voltage for your solar panel. This optimizes power transfer from the panel to the battery.
- Kiashiria cha Kuzingatia: The charge indicator LED will illuminate. A red light indicates fast charging. When the battery is fully charged, the LED will alternate between red and blue, and charging will automatically stop.

6. Maagizo ya Uendeshaji
Once properly connected and adjusted, the Youmile MPPT 5A Solar Charge Controller operates automatically. It continuously tracks the maximum power point of the solar panel to ensure efficient charging.
6.1. Mchakato wa Kuchaji
- The module employs a three-phase intelligent automatic charging mode (constant current, constant voltage, float charge).
- The solar energy tracking feature dynamically adjusts the charging current based on available solar power and battery state.
- The charge indicator LED provides real-time status:
- Nyekundu Imara: Fast charging in progress.
- Alternating Red/Blue: Battery is fully charged. Charging will automatically terminate.
6.2. Utangamano
This controller is versatile and can charge various battery types, including:
- 6V na 12V Betri za Asidi ya risasi
- Nickel-Cadmium (NiCd) Batteries
- Nickel-Metal Hydride (NiMH) Batteries
