3. Instrucțiuni de siguranță

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.
• Folosiți cabluri cu calibru corespunzător pentru toate conexiunile pentru a preveni supraîncălzirea.
• This device is for indoor use only. Avoid exposure to water or excessive humidity.

4. Instalare

4.1 Secvența de cablare

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.

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

4.2 Montare

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. Funcționare

5.1 Afișaj LCD și butoane

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

• Buton SUS: Navigates through display interfaces, increases parameter values.
• Buton JOS: Navigates through display interfaces, decreases parameter values.
• Buton 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 Setări parametri

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.

Parametrii reglabili includ:

• Tip baterie: Select the correct battery type (e.g., Lead-Acid, Lithium).
• Modul de control al încărcăturii: Set timer for load operation (e.g., 24H for continuous, 16H for dusk-to-dawn).
• Încărcare Voltage: Adjust maximum charge voltage.
• Volum de întrerupere a descărcăriitage: Setați volumul minimtage before load disconnection.
• Discharge Reconnect Voltage: Setați volumultage at which the load reconnects.

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

6. Funcții de protecție
