2. Consignes de sécurité
Veuillez respecter les consignes de sécurité suivantes lors de l'installation et du fonctionnement :
- Branchez toujours d'abord la batterie au régulateur de charge, puis le panneau solaire, et enfin la charge. Débranchez-les dans l'ordre inverse.
- Ensure all wiring is correctly sized and connections are secure to prevent loose connections that can cause excessive heating.
- Install the charge controller in a well-ventilated area, away from flammable materials and direct sunlight.
- Do not disassemble or attempt to repair the charge controller. Contact Renogy support for assistance.
- Portez un équipement de protection individuelle approprié, notamment une protection oculaire, lorsque vous travaillez avec des batteries et des systèmes électriques.
- Assurez-vous que le système voltage does not exceed the maximum input voltage of the controller (100V).

5. Configuration et installation
Follow these steps for proper installation of your charge controller:
- Montage: Choose a dry, well-ventilated location for mounting the controller. Ensure there is sufficient clearance around the unit for heat dissipation. Mount vertically on a non-flammable surface.
- Séquence de câblage :
- Raccordez les câbles de la batterie aux bornes de la batterie sur le contrôleur de charge. Assurez-vous de respecter la polarité (+ sur + et - sur -).
- Raccordez les câbles du panneau solaire aux bornes PV du régulateur de charge. Veillez à respecter la polarité.
- Connect the load cables to the load terminals on the charge controller (optional). Ensure correct polarity.
- Capteur de température : Connect the included temperature sensor cable to the designated port on the controller. Place the sensor near the battery to enable accurate temperature compensation for charging.
- Mise sous tension initiale : Once all connections are secure, the controller will power on and display system information on the LCD.
Important: Always connect the battery first and disconnect the battery last to prevent damage to the controller.
6. Mode d'emploi
The LCD display and buttons allow you to monitor and configure the charge controller.
6.1. LCD Display Navigation
Use the buttons on the front panel to navigate through the display screens and adjust settings. Refer to the on-screen prompts for specific actions like 'Select' or 'Enter'.
6.2. Sélection du type de batterie
The controller automatically detects 12V/24V system voltages for non-lithium batteries. For lithium batteries, you must manually adjust the battery voltage setting through the controller's menu to ensure proper charging parameters.
6.3. Lithium Battery Activation
The controller includes a lithium battery activation function. This feature allows charging of deeply discharged lithium batteries that might otherwise be unresponsive.
Figure 6.1: Lithium Activation ON
To prevent over-activation and unnecessary activation, you can turn OFF the lithium activation function. This helps avoid potential damage to the battery if it is not intended for activation.

6.4. Monitoring and Load Control
The LCD provides real-time data on solar input, battery status, and load output. You can also configure load settings, including timers for scheduled operation of connected DC appliances.
7. Entretien
Regular maintenance ensures the longevity and optimal performance of your charge controller:
- Inspecter les connexions : Vérifiez régulièrement le serrage et l'absence de corrosion de tous les raccords électriques. Assurez-vous qu'aucun fil n'est effiloché ou endommagé.
- Nettoyer le contrôleur : Veillez à ce que la manette reste propre et exempte de poussière et de débris. Essuyez sa surface avec un chiffon sec. N'utilisez ni liquides ni solvants.
- Ventilation: Veillez à ce que la zone d'installation reste bien ventilée afin d'éviter toute surchauffe.
- Inspection de la batterie : Regularly inspect your batteries for any signs of damage, swelling, or leaks.
