3. Pengaturan & Instalasi

Follow these steps carefully to ensure correct and safe installation. The correct connection order is crucial for preventing damage to the controller and batteries.

1. Connect to the Battery: Pertama, hubungkan baterai ke terminal baterai pengontrol. Pastikan polaritasnya benar (positif ke positif, negatif ke negatif).
2. Connect to the DC Load Terminal: Next, connect your DC loads (e.g., lights, pumps) to the controller's load terminals.
3. Connect to the Solar Panel: Finally, connect the solar panels to the controller's PV input terminals. Ensure correct polarity.

Important: Always connect the battery first and disconnect the solar panel first when disassembling the system.

4. Petunjuk Pengoperasian

The controller features an LCD display and intuitive buttons for monitoring and configuration.

4.1. Layar LCD dan Tombol

The LCD display shows real-time system parameters such as battery voltage, charging current, load status, and error codes. Use the ENTER, UP, and DOWN buttons to navigate menus and adjust settings.

4.2. Mode Pengisian Daya

The controller employs a 3-stage smart charging algorithm to optimize battery health and longevity:

• Biaya massal: Charges the battery at maximum current until it reaches the absorption voltage.
• Biaya Penyerapan: Mempertahankan volume konstantage while the current gradually decreases, ensuring the battery is fully charged without overcharging.
• Biaya mengambang: Reduces the voltagke tingkat yang lebih rendah untuk menjaga baterai tetap terisi penuh, sebagai kompensasi atas pengosongan daya sendiri.
