Configuració

1. Desembalatge i inspecció

Carefully unpack the EPEVER VS4524AU solar charge controller. Inspect the device for any visible damage that may have occurred during transit. Ensure all components listed in the packaging are present. If any damage or missing parts are found, contact your supplier immediately.

2. Muntatge del controlador

Choose a suitable location for mounting the controller. The location should be:

• Indoors, protected from direct sunlight, high temperatures, and water.
• Well-ventilated to allow for proper heat dissipation.
• Close to the battery bank, but in a separate enclosure if possible, to minimize voltage gota.

Mount the controller vertically on a flat, non-flammable surface using appropriate screws. Ensure there is sufficient clearance around the controller for airflow, especially above and below the heat sink fins.

3. Connexions de cablejat

Nota important de seguretat: Before making any connections, ensure that the solar panels are covered or disconnected from the system to prevent accidental power generation. Disconnect any loads from the battery. Always connect the battery first, then the solar panel, and finally the load.

1. Connecteu la bateria: Connect the positive and negative terminals of the battery to the corresponding battery terminals on the controller. Observe correct polarity. The controller's LCD will illuminate if the battery connection is successful.
2. Connecteu el panell solar: Connect the positive and negative terminals of the solar panel array to the corresponding solar panel terminals on the controller. Ensure correct polarity.
3. Connecteu la càrrega de CC (opcional): Connect the positive and negative terminals of your DC loads to the corresponding load terminals on the controller. Note that the USB ports are also available for charging small electronic devices.

Ensure all wire connections are tight and secure to prevent loose connections and potential hazards. Use appropriate wire gauges for your system's current and distance to minimize voltage gota.

Instruccions de funcionament

1. LCD Display Overview

The LCD display provides real-time information about the system's status, including battery voltage, charging current, load current, and various operational parameters. Use the "MENU" and "SET" buttons to navigate through the display screens and adjust settings.

2. Funcions del botó

• Botó MENÚ:
  • Short press: Cycles through different display screens (e.g., battery voltage, solar current, load current).
  • Long press: Enters or exits the parameter setting mode.
• Botó SET:
  • Short press: Increases the value of a parameter in setting mode or switches between options.
  • Long press: Confirms the selected parameter value or setting.

3. Modes de càrrega

El controlador utilitza un sistema de 3 segonstage PWM charging algorithm to optimize battery charging and prolong battery life:

• Càrrega massiva: Quan la bateria voltage is below the Boost/Equalize voltage, the controller delivers maximum current to rapidly charge the battery.
• Boost/Equalize Charge: Once the battery reaches the Boost voltage, the controller maintains a constant voltage for a set period to ensure the battery is fully charged. An Equalize charge may be performed periodically for flooded batteries to balance cell voltages.
• Càrrega del flotador: After the Boost/Equalize stage, the controller reduces the voltage to a lower "float" level to maintain the battery at full charge without overcharging.

4. Load Control Modes

The controller offers various load control modes to manage the DC output:

• Mode manual: The load can be turned on or off manually via the controller's buttons.
• Mode de control de la llum: The load automatically turns on at dusk and off at dawn, based on solar panel voltage.
• Dual-Time Mode: Combines light control with a timed duration for the load to be on after dusk.
• Mode de depuració: Used for testing and troubleshooting, allowing manual control of the load regardless of light conditions.

Refer to the detailed settings menu on the LCD for configuring these modes and other parameters like battery type, load timer, and protection thresholds.

Manteniment

Regular maintenance ensures the longevity and optimal performance of your EPEVER solar charge controller:

• Comproveu les connexions: Periodically inspect all wiring connections (battery, solar panel, load) to ensure they are tight and free from corrosion. Loose connections can cause voltaggotes de líquids i sobreescalfament.
• Netegeu el controlador: Keep the controller clean and free from dust and debris. Use a dry cloth to wipe the casing and ensure the heat sink fins are not obstructed, as this can impair cooling.
• Monitoritzar el rendiment: Regularly check the LCD display for system parameters (battery voltage, charging current, load current) to ensure the system is operating within expected ranges.
• Inspecció de la bateria: For flooded batteries, check electrolyte levels and specific gravity periodically. Ensure battery terminals are clean and free of corrosion.
• Control ambiental: Assegureu-vos que l'entorn d'instal·lació es mantingui dins dels rangs de temperatura i humitat especificats.
