4. Configuração e instalação
Ambiente de instalação:
The controller should be installed in a well-ventilated place. Avoid direct sunlight and high temperatures. Do not install in locations where water can enter the controller.
Image: Dimensions & Cables. This image provides the physical dimensions of the controller and general guidelines for cable connections, emphasizing proper ventilation and avoiding water exposure.
Etapas de fiação:
Follow these steps carefully for proper wiring. Incorrect wiring can damage the controller or other components.
Image: How to Wire. This diagram illustrates the correct sequence for connecting the battery, solar panel, and load to the charge controller.
- Abra a tampa: Unscrew and remove the terminal cover to access the wiring ports.
- Conecte a bateria: First, connect the battery to the controller's battery terminals (marked with a battery symbol). Ensure correct polarity (+ to + and - to -).
- Conecte o painel solar: Next, connect the solar panel to the controller's PV input terminals (marked with a solar panel symbol). Ensure correct polarity.
- Conecte a carga (opcional): Finally, connect your DC load to the controller's load terminals (marked with a light bulb symbol). Ensure correct polarity.
The controller will automatically detect 12V or 24V systems. Ensure your battery bank voltage corresponde ao vol do sistematage.

5. Instruções de operação
Interface de exibição LCD:
The large LCD display provides real-time information about your system. Press the "MENU" button to view parameters and cycle through different screens. Press the "SET" button to enter settings mode and adjust parameters.
Image: Quick-View Interface de exibição. Esta imagem mostra examples of the information displayed on the LCD, such as main interface, total charge power, float voltage, sistema voltage select, load reconnect voltage, and load disconnect voltage.
Load Working Modes:
The controller offers several load working modes to suit different applications:
Image: Load Working Mode. This image details the Manual Mode (24H), Solar Light Control Mode (Sunset-Sunrise), and Solar Light + Time Control modes.
- Modo manual (24 horas): A saída de carga permanece ligada continuamente por 24 horas.
- Solar Light Control Mode: The load turns on at sunset and off at sunrise.
- Solar Light + Time Control Mode: The load turns on at sunset and stays on for a set number of hours, then turns off.
- Charge-Only Mode: The controller focuses solely on charging the battery, with no load output.
Ativação da bateria de lítio:
For lithium batteries with zero voltage, the MPPT controller can activate them upon startup. For battery safety, when the battery voltage atinge um alto volumetage disconnection point, the controller will initiate a PWM charging function to activate the battery and restore it to 100%.

6. Manutenção
- Inspecione regularmente todas as conexões de fiação para verificar se estão bem apertadas e se há corrosão.
- Mantenha o controlador limpo e livre de poeira e detritos. Use um pano seco para a limpeza.
- Certifique-se de que as aberturas de ventilação não estejam bloqueadas para evitar superaquecimento.
- Verifique periodicamente os terminais da bateria quanto à corrosão e limpe-os, se necessário.
- Monitore o visor LCD para verificar se há códigos de erro ou leituras incomuns.
