• Support for three battery charging options: Sealed, Gel, and Flooded.
• Intuitive LED indicators to display battery status.
• Battery temperature compensation function for optimized charging.
• User-friendly settings for comfortable and convenient operation.
• USB port providing 5VDC/1.2A power output for charging electronic equipment.
• Ability to set battery type and load output via a single button.
• Extensive electronic protection features.

2. Informació important de seguretat

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

• DO NOT disassemble or attempt to repair the controller. Unauthorized modifications can void the warranty and pose safety risks.
• Install an external fuse or circuit breaker as required for proper system protection.
• Always disconnect the solar module and any fuses/breakers near the battery before installing, moving, or performing maintenance on the controller. This prevents electrical shock.
• Ensure all power connections remain tight to avoid excessive heating from loose connections, which can lead to fire hazards.
• Only charge batteries that comply with the parameters specified for this controller. Using incompatible batteries may cause damage.
• The battery connection can be wired to a single battery or a bank of batteries, ensuring correct polarity.
• Be aware of the risk of electric shock: the PV (photovoltaic) array and load can produce high voltages when the controller is operating.

4. Configuració i instal·lació

Proper installation is crucial for the safe and efficient operation of your EPEVER LS0512EU solar charge controller. Follow these steps carefully.

Passos d'instal·lació:

1. Preparació per a la instal·lació: Ensure all power sources are disconnected. Choose a dry, well-ventilated location away from direct sunlight and heat sources. The controller should be mounted vertically on a non-flammable surface.
2. Muntar el controlador: Use the mounting holes (①) to securely fasten the controller to your chosen surface.
3. Connecteu la bateria: Connect the battery to the Battery Terminals (③). Ensure correct polarity: positive to positive (+) and negative to negative (-). It is highly recommended to install a fuse or circuit breaker between the battery and the controller, as close to the battery as possible.
4. Connect the Load: Connect your DC loads to the Load Terminals (④). Again, ensure correct polarity.
5. Connect the Solar Panel (PV Array): Connect the solar panel to the PV Terminals (②). Ensure correct polarity. The controller will automatically detect the system voltage (12 V).

This image illustrates the proper wiring sequence for connecting a solar panel, battery, and DC load to the EPEVER LS0512EU solar charge controller, demonstrating the flow of power within the system.

Wiring Order Precaution: Always connect the battery first, then the load, and finally the solar panel. When disconnecting, reverse the order: disconnect the solar panel first, then the load, and finally the battery.

5. Instruccions de funcionament

The EPEVER LS0512EU controller is designed for straightforward operation. Once connected, it will automatically begin charging the battery from the solar panel.

Indicadors LED:

• Battery Status LED (⑦): Indica el volum actual de la bateriatage level and charging state (e.g., full, normal, low voltage disconnect).
• Load Status LED (⑧): Shows whether the load output is ON or OFF, and indicates overload or short-circuit conditions.
• Charging Status LED (⑨): Displays the charging activity from the solar panel to the battery, including overvoltage condicions.

Button Operation (⑥):

The single button on the controller allows for basic settings and load control.

• Load ON/OFF Control: A short press of the button will toggle the DC load output ON or OFF.
• Battery Type Setting: Press and hold the button for approximately 5 seconds to enter the battery type setting mode. The battery status LED will flash. Short press the button to cycle through the battery types (Sealed, Gel, Flooded). Release the button to confirm the selection.

Sortida USB:

The USB Output Port (⑤) provides a stable 5VDC/1.2A power supply for charging small electronic devices such as smartphones or tablets. This output is active when the controller has sufficient battery voltage.

6. Manteniment

Regular maintenance ensures the longevity and optimal performance of your EPEVER LS0512EU solar charge controller and the entire solar system.

• Comproveu les connexions: Periodically inspect all wiring connections to ensure they are tight and free from corrosion. Loose connections can cause excessive heat and system malfunction.
• Netegeu el controlador: Mantingueu el controlador net i lliure de pols i brutícia. Feu servir un drap sec per netejar la superfície. No utilitzeu netejadors líquids.
• Inspeccioneu el cablejat: Check the insulation of all wires for any signs of damage, wear, or fraying. Replace damaged wires immediately.
• Inspecció de la bateria: Regularly check the battery terminals for corrosion and clean them if necessary. For flooded batteries, check electrolyte levels and top up with distilled water as needed.
• Control ambiental: Assegureu-vos que l'entorn d'instal·lació estigui sec, ben ventilat i dins del rang de temperatura de funcionament especificat.

7. Solució De Problemes

This section provides solutions to common issues you might encounter with your EPEVER LS0512EU solar charge controller.

Problemes comuns i solucions:

• No LED Indication:
  Possible causa: Battery not connected or reverse polarity; battery voltage massa baix.
  Solució: Comproveu les connexions i la polaritat de la bateria. Assegureu-vos del volum de la bateria.tage supera els 8V.
• Charging LED Off or Flashing:
  Possible causa: Solar panel not connected, reverse polarity, or insufficient sunlight; PV overvoltage.
  Solució: Check PV connections and polarity. Ensure adequate sunlight. If flashing, check PV open circuit voltage (should be below 30V).
• La càrrega no funciona:
  Possible causa: Load output OFF; battery low voltage disconnect (LVD); load overload/short-circuit; load not connected.
  Solució: Press the button to turn load ON. Check battery voltage (must be above LVD). Disconnect load, check for short-circuit, reduce load, then reconnect. Verify load connections.
• USB Output Not Working:
  Possible causa: Bateria voltage too low; USB device drawing too much current.
  Solució: Assegureu-vos que la bateria voltage is sufficient. Check USB device current draw (max 1.2A).
