• Non instale o controlador en ambientes húmidos, con alto nivel de sal, corroídos, graxos, inflamables, explosivos, acumulados de po ou outros ambientes severos.
• Be careful when installing batteries. Wear eye protection when installing open-type lead-acid batteries and rinse with clean water immediately if battery acid contacts skin.
• Keep batteries away from metal objects to prevent short circuits.
• Ensure the surrounding environment is well ventilated, as acid gas may be generated when batteries are charged.
• Avoid direct sunlight and rain infiltration when installing outdoors.
• Ensure tight power connections and secure cables with clamps to prevent high heat from loose connections.
• Only charge lead-acid and lithium-ion batteries within the control range of this controller.
• The battery connector can be wired to a single battery or a bank of batteries.
• Select system cables according to 5A/mm² or less current density.
• The grounding wire size should not be less than 4mm².
• The torque for tightening wiring screws should not be less than 1.2 N·m.

6.2 Requirements for the PV Array

The controller needs to suit various types of PV modules. The serial connection of PV modules suitable for different controllers can be calculated based on the open-circuit voltage (Voc) e o punto de máxima potencia voltage (VMPP) of the MPPT controller. Refer to the technical specifications for detailed values.

6.3 Tamaño do fío

Os métodos de cableado e instalación deben axustarse aos requisitos do código eléctrico nacional e local.

Tamaño do cable fotovoltaico

The PV array's output current varies with size, connection method, and sunlight angle. The minimum wire size can be calculated using the ISC (short circuit current) from the PV module's specifications. The PV array's ISC must not exceed the controller's maximum PV input current.

Tamaño da batería e cable de carga

The battery and load wire size should conform to the rated current.

6.4 Montaxe

O controlador require polo menos 150 mm de espazo libre arriba e abaixo para un fluxo de aire adecuado. A ventilación é moi recomendable se se monta nun recinto.

Step 1: Determine the installation location and heat-dissipation space.

6.5 Diagrama de cableado

Step 2: Connect the system in the order of ①battery > ②load > ③PV array by the following schematic wiring diagram, and disconnect the system in the reverse order.

7.5 Carga de batería Stages

The controller employs a three-stage battery charging algorithm: Bulk Charging, Constant Charging (Equalize and Boost), and Float Charging. This method extends battery lifespan.

1. Carga masiva: A batería voltage aínda non alcanzou o vol constantetage. The controller operates in constant current mode, delivering maximum current (MPPT Charging).
2. Carga constante: Unha vez que a batería voltage alcanza a constante voltage set point, the controller switches to constant charging mode. MPPT charging stops, and the charging current gradually drops. This stage includes Equalize Charging (on the 28th of each month) and Boost Charging (default 2 hours).
3. Carga flotante: After constant charging, the controller reduces battery voltage ao volume predeterminado de carga flotantetage by reducing current. The battery is weakly charged to maintain a fully charged state. If load power exceeds solar array power, the controller will no longer maintain float charging. The system exits float charging and re-enters bulk charging if battery voltage drops below the boost voltage reconectar voltage.

7.6 Load Modes

The controller offers multiple load work modes. When the LCD shows the load type interface, operate as follows:

1. Preme o botón SELECCIONAR para ir á interface do tipo de carga.
2. Manteña premido o botón ENTER ata que parpadee a interface do tipo de carga.
3. Prema o botón SELECCIONAR para modificar o tipo de carga.
4. Preme o botón ENTER para confirmar.

8. Proteccións

When the controller's internal temperature reaches 81°C, the charging power automatic reduction function is enabled. Temperature increases by 1°C, and the charging power is reduced by 5%, 10%, 20%, and 40%. If the internal temperature exceeds 85°C, the controller stops charging the battery. When the internal temperature is lower than or equal to 75°C, the controller resumes charging per the rated charging power.

• Wiring Sequence is Crucial: Always connect the battery first, then the PV array, and finally the load. Disconnect in reverse order. This prevents damage to the controller.
• Monitor Batería Voltage: Asegúrese de que a súa batería voltage is at least 8V for the controller to activate. If it's below this, you may need to charge it externally first.
• Utilize Communication Modules: For advanced monitoring and parameter adjustments, consider using the optional WiFi or Bluetooth modules with the EPEVER APP, or connect to a PC with the appropriate cable and software.
• Ventilación adecuada: Adequate airflow around the controller is essential to prevent overheating, especially during high power operation. Ensure the 150mm clearance is maintained.
• Custom Battery Settings: If using a 'User' defined battery type, carefully review and set all voltage parameters according to your battery manufacturer's specifications to optimize performance and lifespan.
• Mantemento regular: Perform the recommended bi-annual maintenance checks to ensure all connections are tight, clean, and free from damage, which will prolong the life of your system.
