Follow these steps for proper installation of your MPPT solar charge controller. Refer to the wiring diagram for visual guidance.
4.1 Mchoro wa Wiring

Figure 4: MPPT Charge Controller System Wiring Diagram
4.2 Hatua za Ufungaji
- Kupachika: Mount the controller vertically on a non-flammable surface in a cool, dry, and well-ventilated area. Ensure adequate clearance around the unit for heat dissipation.
- Muunganisho wa Betri: Connect the battery cables to the controller's BAT+ and BAT- terminals. Ensure correct polarity. The controller will automatically detect the battery voltage (12V, 24V, au 48V).
- Muunganisho wa Paneli ya Jua: Connect the solar panel array cables to the controller's PV+ and PV- terminals. Ensure correct polarity. The controller will begin charging the battery.
- Muunganisho wa Mzigo (Si lazima): If using the load output, connect your DC loads to the OUT+ and OUT- terminals. Ensure the total current draw does not exceed the controller's rated load current.
- Thibitisha Miunganisho: Double-check all connections for tightness and correct polarity before powering on the system.
Important: Always connect the battery first and disconnect it last. Failure to follow this sequence may damage the controller.
5. Maagizo ya Uendeshaji
The controller's LCD display provides real-time system status and allows for parameter adjustments. The control buttons are PRG/ESC, Up (▲), Down (▼), and ENTER.
5.1 Kazi za Kuonyesha LCD
The LCD cycles through various screens displaying system information. You can manually cycle through screens using the Up/Down buttons or enter parameter settings using PRG/ESC and ENTER.
- Onyesho Kuu: Shows charging status, battery level, and output status.
- Uzalishaji wa Nguvu Mjumuisho: Displays total energy generated by the solar panels.
- Voltage and Load Power: Shows current solar panel voltage and load power consumption.
- Betri Voltage and Load Current: Inaonyesha ujazo wa betri ya sasatage na mzigo wa sasa.
- Accumulated Discharge: Shows total energy discharged from the battery.
- Halijoto ya Ndani: Huonyesha halijoto ya ndani ya kidhibiti.

5.2 Marekebisho ya Vigezo
To enter parameter adjustment mode, press the PRG/ESC kitufe. Tumia Up (▲) na Chini (▼) buttons to navigate through parameters and adjust values. Press INGIA to confirm changes. Press PRG/ESC tena ili kutoka kwenye hali ya mipangilio.
Vigezo vya kawaida vinavyoweza kurekebishwa ni pamoja na:
- b00: Load working mode (e.g., 24H for continuous, or timed modes).
- b01: Ulinzi wa malipo ya ziada ujazotage (e.g., 55.2V for 48V system).
- b02: Inachaji ahueni juzuu yatage (e.g., 58.0V for 48V system).
- b03: Ulinzi wa kutokwa na maji kupita kiasi juzuu yatage (e.g., 40.0V for 48V system).
- b04: Kupona kutekelezwa zaidi voltage.
- b06: Battery type setting (e.g., 47.9V for a specific battery type).
