3. Configurare și instalare
Proper installation is crucial for the safe and efficient operation of your solar charge controller. Please follow these steps carefully:
- Pregătirea cablajului: Ensure all wires are of appropriate gauge for the current and length, and that all connections are clean and secure.
- Conectați bateria: Connect the battery to the charge controller first. Ensure correct polarity (+ to + and - to -). The controller will automatically detect the system voltage (12V sau 24V).
- Conectați panoul solar: Connect the solar panel array to the charge controller. Again, observe correct polarity. The controller will begin charging the battery.
- Conectarea sarcinii: Finally, connect the DC load to the charge controller's load terminals. Do not exceed the maximum rated load current.
Important: Always connect the battery first and disconnect the battery last to prevent damage to the controller.

4. Instrucțiuni de utilizare
4.1. Afișaj LCD
The LCD display provides real-time information about the system's status. It shows battery voltage, charging current, discharging current, battery state of charge, and various error indicators.
Figure 3: Close-up of the LCD display and control buttons for navigation and settings.
4.2. Funcții butoane
The controller features two buttons for navigation and setting adjustments:
- Left Button (Menu/Select): Used to cycle through display screens and enter/confirm settings.
- Right Button (Up/Adjust): Used to increase values or navigate options within settings.
4.3. Moduri de control al sarcinii
The controller supports multiple load control modes to suit different application needs:
- Modul normal: Load is continuously ON or OFF based on manual setting.
- Modul senzor: Load turns ON automatically when it gets dark and OFF when it gets light (e.g., for street lights).
- Modul temporizator: Load turns ON when it gets dark and stays ON for a set number of hours.
4.4. Selectarea tipului de baterie
To ensure optimal charging, select the correct battery type in the controller settings:
- Sigilat: For sealed lead-acid batteries.
- Gel: For gel batteries.
- Inundat: For flooded (wet cell) lead-acid batteries.
Refer to the detailed instructions in the full manual for specific steps on navigating menus and adjusting settings.
5. Întreținere
Întreținerea regulată asigură longevitatea și performanța optimă a regulatorului de încărcare solară:
- Curăţenie: Păstrați controlerul curat și fără praf și resturi. Folosiți o cârpă uscată pentru curățare.
- Verificări de conectare: Verificați periodic toate conexiunile cablurilor pentru a vă asigura că sunt strânse și fără coroziune. Conexiunile slăbite pot cauza supraîncălzirea și performanțe slabe.
- Ventilare: Ensure the controller has adequate ventilation to prevent overheating. Do not block ventilation holes.
- Conditii de mediu: Operate the controller within its specified temperature range (-20℃ to +55℃) and avoid exposure to direct sunlight or excessive moisture. The waterproof grade is IP32.
6. Depanare
This section outlines common issues and their potential solutions. The controller features comprehensive digital protection functions to prevent damage.
| Problemă | Cauza posibila | Soluţie |
|---|---|---|
| Afișajul controlerului este oprit. | Battery not connected or reverse polarity; battery voltage prea jos. | Verificați conexiunile bateriei și polaritatea. Asigurați-vă că bateria estetage is above LVD (Low Voltage Disconnection) threshold. |
| Bateria nu se încarcă. | Solar panel not connected or reverse polarity; insufficient sunlight; PV input voltage prea jos. | Check solar panel connections and polarity. Ensure adequate sunlight. Verify PV voltage se încadrează în specificații. |
| Load not working. | Load over current; short circuit; battery voltage too low (LVD); load control mode setting. | Check load current and wiring for short circuits. The controller has load over current protection (auto restart every 30s). Check battery voltage. Adjust load control mode settings. |
| Supraîncălzirea controlerului. | Poor ventilation; excessive load or charging current. | Ensure proper airflow around the controller. Reduce load or charging current if consistently high. |
