2. Consignes de sécurité

Please read all instructions carefully before installation and operation. Failure to follow these instructions may result in damage to the unit, battery, or other components, and may cause personal injury.

• Ensure all connections are tight and correct to prevent excessive voltage drop and potential overheating.
• Branchez toujours d'abord la batterie au contrôleur, puis le panneau solaire, et enfin la charge. Débranchez-les dans l'ordre inverse.
• Do not attempt to repair or modify the controller. Refer to qualified personnel for service.
• Installez le contrôleur dans un endroit bien ventilé, à l'écart des matériaux inflammables et de la lumière directe du soleil.
• The controller is rated IP32, meaning it is protected from tools and wires greater than 2.5 millimeters and from spraying water. It is not waterproof and should not be exposed to heavy rain or submerged.

5. Installation

Follow these steps for proper installation of your solar charge controller. Incorrect wiring can damage the controller and other components.

5.1. Méthode de connexion

1. Connectez la batterie : Connect the battery to the controller's battery terminals (marked with a battery symbol). Ensure correct polarity (+ to + and - to -). The controller will automatically detect the battery voltage (12V ou 24V).
2. Connecter le panneau solaire : Raccordez le panneau solaire aux bornes prévues à cet effet sur le contrôleur (marquées d'un symbole de panneau solaire). Veillez à respecter la polarité.
3. Connectez la charge : Raccordez vos charges CC aux bornes de charge du contrôleur (repérées par un symbole d'ampoule). Assurez-vous de respecter la polarité.

Important: Always connect the battery first and disconnect the load first, then the solar panel, and finally the battery when disassembling the system.

6. Mode d'emploi

The controller features an LCD display and control buttons for monitoring and adjusting settings.

6.1. Écran LCD

The LCD display provides real-time information about your solar system, including:

• Vol panneau solairetage et l'état de charge.
• Vol batterietage et niveau de charge.
• Load status (on/off) and current.
• Vol systèmetage (12V ou 24V).

6.2. Ajustement du volumetagParamètres

The controller allows for manual adjustment of certain voltage parameters, such as the over-discharge recovery voltage. If you encounter issues or need to fine-tune your system, you can adjust the voltage:

1. Press and hold the MCU control button (usually the 'Menu' or 'Set' button) for approximately 3-4 seconds. This will bring up a management interface on the display.
2. Use the 'Add' button (or 'Up' arrow) to navigate through the settings and increase the voltage value until it reaches your desired setting, for example, 13.7V for battery recovery.
3. Press the MCU control button again to save the new setting. The display will stop flashing, indicating the data has been saved.

6.3. USB Output Usage

The dual USB ports can be used to charge various 5V devices, such as mobile phones, driving recorders, and cameras.

7. Entretien

Un entretien régulier garantit des performances optimales et une longue durée de vie à votre régulateur de charge solaire.

• Nettoyage: Periodically clean the controller's exterior with a dry cloth to remove dust and dirt. Ensure the display remains clear.
• Vérification de la connexion : Annually inspect all wiring connections to ensure they are secure and free from corrosion. Loose connections can cause overheating and damage.
• Ventilation: Veillez à ce que la zone d'installation reste bien ventilée afin d'éviter toute surchauffe du contrôleur.

8. Dépannage

Cette section aborde les problèmes courants et leurs solutions.

8.1. No Output from Load Terminals

• Symptôme: The load connected to the controller is not receiving power.
• Cause possible : Vol batterietage is too low. The controller automatically stops output when battery voltage drops below a certain threshold (e.g., 10.5V-11V for a 12V system) to protect the battery from over-discharge.
• Solution: Allow the solar panel to charge the battery. The controller will resume load output once the battery voltage recovers to 12.6V (for a 12V system).

8.2. Volume incorrecttage Readings or Charging Behavior

• Symptôme: The display shows unexpected voltage values, or charging seems inefficient.
• Cause possible : Voltage settings may be misconfigured or require adjustment. The normal operating voltage range for the controller is typically 10.7V to 13.7V (for a 12V system).
• Solution: Refer to Section 6.2 "Adjusting Voltage Settings" to manually adjust the voltage parameters, such as setting the recovery voltage to 13.7V if needed.
