3. Configuration et installation

Une installation correcte est essentielle au fonctionnement sûr et efficace de votre régulateur de charge solaire. Suivez attentivement les étapes suivantes :

1. Montage: Secure the controller to a flat, vertical surface using the mounting holes (Φ4.5). Ensure adequate ventilation around the controller.
2. Connexion de la batterie : Connect the battery to the battery terminals (③) first. Ensure correct polarity (positive to positive, negative to negative) to avoid reverse polarity protection activation. The controller is designed for 12V systems and supports Sealed, Gel, and Flooded battery types.
3. Connexion du panneau solaire : Connect the solar panel to the PV terminals (②). Ensure correct polarity. The maximum PV open circuit voltage ne doit pas dépasser 30V.
4. Connexion de charge : Connect your DC loads to the load terminals (④). Ensure the total current draw of your loads does not exceed the controller's rated current.

Important : Branchez toujours d’abord la batterie, puis le panneau solaire, et enfin la charge. Débranchez-les dans l’ordre inverse : charge, puis panneau solaire, puis batterie.

The controller features a common positive grounding type.

4. Mode d'emploi

Once installed, the controller operates automatically to manage your solar charging system.

Indicateurs LED :

• Charging Status LED (⑨): Indicates the charging status from the solar panel to the battery.
• Battery Status LED (⑦): Displays the current state of charge of the battery.
• Load Status LED (⑧): Shows the status of the connected DC loads (ON/OFF, overload, short-circuit).

Port de sortie USB :

The controller includes a USB output port (⑤) providing 5V/1.2A for charging small electronic devices.

Button Function (⑥):

The button on the controller is typically used for manual control of the load output (e.g., turning the load ON/OFF). Refer to the specific LED indicator patterns for detailed operational feedback.

5. Entretien

To ensure optimal performance and longevity of your EPEVER LS1012EU solar charge controller, regular maintenance is recommended:

• Propreté: Veillez à ce que la manette reste propre et exempte de poussière et de débris. Utilisez un chiffon sec pour la nettoyer.
• Relations: Periodically check all wire connections to ensure they are tight and secure. Loose connections can cause overheating and damage.
• Ventilation: Ensure that the controller's ventilation openings are not blocked to allow for proper heat dissipation.
• État de la batterie : Surveillez l'état et le volume de votre batterie.tage regularly. Ensure the battery type setting (if adjustable) matches your battery.

6. Dépannage

Si vous rencontrez des problèmes avec votre manette, consultez les problèmes et solutions courants suivants :

• Aucune indication de charge :
  • Check solar panel connections and ensure they are correctly polarized.
  • Verify that the solar panel is receiving sufficient sunlight.
  • Confirm battery connections are secure and correctly polarized.
• Chargement impossible :
  • Check load connections for proper polarity and security.
  • Verify that the total load current does not exceed the controller's rating (10A for LS1012EU).
  • Check the load status LED (⑧) for overload or short-circuit indications.
  • Assurez-vous que la batterie voltage est au dessus du faible voltage déconnecter voltage (11.1V). The load will automatically reconnect when the battery voltage atteint 12.6 V.
• Battery Over-Discharge:
  • The controller will disconnect the load if the battery voltage drops to 11.1V to protect the battery.
  • Ensure adequate solar input to recharge the battery.
  • Reduce load consumption if over-discharge occurs frequently.
• Protection contre l'inversion de polarité :
  • If battery or solar panel connections are reversed, the controller's protection mechanism will prevent damage. Correct the polarity immediately.
