4. Instal·lació i cablejat
Proper installation is crucial for the safe and efficient operation of your solar charge controller. Please follow these steps carefully.
4.1 Wiring Sequence
- Connect the battery to the charge controller first. Ensure correct polarity.
- Connect the solar panel(s) to the charge controller. Ensure correct polarity.
- Connect the DC load (if any) to the charge controller. Ensure correct polarity.
Important Safety Note: Always connect the battery first and disconnect it last. Incorrect wiring sequence or reverse polarity can damage the controller and other components.
4.2 Battery Type Compatibility
The controller is compatible with various common battery types, including Lead Acid (GEL, FLD, AGM, SEL) and Lithium (LiPo, LiFe) batteries. Ensure you select the correct battery type in the controller settings for optimal charging and protection.
Figure 4: Diagram illustrating compatibility with various 12V/24V battery types, including Lithium (LiPo, LiFe), Sealed (SEL), Flooded (FLD), Gel (GEL), and AGM.
5. Operation and Load Modes
The controller operates continuously and offers four distinct load operating modes to suit various application needs.
5.1 Load Operating Modes
Figure 5: Visual representation of the four load operating modes.
- LD1 (Regular Mode): The load functions normally and can be manually switched on or off via the controller's buttons.
- LD2 (Light Control Mode): The load automatically turns on at dusk (when ambient light falls below a threshold) and turns off at dawn (when ambient light rises above a threshold).
- LD3 (Light and Time Control Mode): This mode combines light sensing with a timer. The load turns on at dusk and operates for a set duration, then turns off. It can also be configured to turn on for a set duration before dawn. The controller automatically detects darkness and light based on the local environment.
- LD4 (Light Inversion Control Mode): In this mode, the load automatically turns on at sunrise and automatically shuts off at night. This is an inverted light control, suitable for specific applications where the load needs to be active during daylight hours.
6. Funcions de protecció
The Anern MPPT Solar Charge Controller is equipped with multiple intelligent protection features to ensure the safety and longevity of your system components.
Figure 6: Diagram illustrating the various protection functions of the controller.
- Solar Panel Reverse Polarity Protection: Prevents damage if the solar panel is connected with incorrect polarity.
- Protecció contra la polaritat inversa de la bateria: Protects the controller and battery from damage if the battery is connected with incorrect polarity.
- Sobrevol de bateriatage Protecció: Automatically stops charging when the battery voltage arriba a l'overvoltage threshold, preventing overcharging.
- Battery Over-discharge Protection: Disconnects the load when the battery voltage cau per sota del undervoltage point, preventing deep discharge and extending battery life.
- Load Overload Protection: Disconnects the load if the current exceeds the rated current, protecting the controller and connected devices.
- Protecció contra curtcircuits: Automatically shuts down in case of a short circuit in the load or wiring.
- Open Circuit Protection: Ensures safe operation even if a circuit is inadvertently opened.
7. Manteniment
To ensure optimal performance and longevity of your Anern MPPT Solar Charge Controller, periodic maintenance is recommended.
