3. Arahan Keselamatan

Please read all instructions carefully before installation and operation. Failure to follow these instructions may result in damage to the controller, battery, or solar panels, and may void the warranty.

• Ensure the battery is connected first to allow the controller to recognize the system voltage.
• Always connect the solar panels and load after the battery.
• Disconnect the solar panels and load before disconnecting the battery.
• Install the controller in a well-ventilated, dry, and cool environment, away from flammable materials.
• Avoid touching or short-circuiting wires or terminals.
• Gunakan tolok wayar yang sesuai untuk semua sambungan bagi mengelakkan terlalu panas.
• This device is for indoor use only. Avoid exposure to water or excessive humidity.
• Jauhkan daripada kanak-kanak.

4. Pemasangan

4.1 Wiring Sequence

1. Connect the battery to the charge controller. Ensure correct polarity (+ to + and - to -). The controller will display the battery voltage.
2. Connect the solar panel to the charge controller. Ensure correct polarity. The controller will begin charging the battery.
3. Connect the load to the charge controller. Ensure correct polarity.

Penting: Always connect the battery first and disconnect it last. This sequence prevents damage to the controller from voltage melonjak.

4.2 Pemasangan

Mount the controller vertically on a wall or flat surface in a well-ventilated area, away from direct sunlight, high temperatures, and water. Ensure there is sufficient air circulation around the heat sink.

5. Operasi

5.1 Paparan LCD dan Butang

The controller features an LCD display and three buttons for operation: UP, DOWN, and SET.

• Butang KE ATAS: Navigates through display interfaces, increases parameter values.
• Butang TURUN: Navigates through display interfaces, decreases parameter values.
• Butang SET: Enters/exits setting mode, confirms parameter changes.

5.2 Browsing Display Interfaces

Press the UP or DOWN button to cycle through various display interfaces, including battery voltage, charging current, accumulated discharge, and load status.

5.3 Tetapan Parameter

To enter the setting interface, long-press the SET button for 5 seconds. Use the UP and DOWN buttons to adjust values and the SET button to confirm and move to the next parameter. Long-press SET again to save changes and exit.

Adjustable parameters include:

• Jenis Bateri: Select the correct battery type (e.g., Lead-Acid, Lithium).
• Mod Kawalan Beban: Set timer for load operation (e.g., 24H for continuous, 16H for dusk-to-dawn).
• Caj Voltage: Adjust maximum charge voltage.
• Pelepasan Pelepasan Voltage: Tetapkan vol minimumtage before load disconnection.
• Discharge Reconnect Voltage: Tetapkan voltage at which the load reconnects.

Refer to the "Specifications" section for default and adjustable ranges for each parameter.

6. Fungsi Perlindungan
