2. Informații de siguranță

Please read all instructions carefully before installation and operation to prevent damage to the controller, battery, or other components.

• Ensure all wiring is correct and connections are secure before applying power. Incorrect wiring can cause damage.
• Conectați întotdeauna mai întâi bateria, apoi panoul solar și în final sarcina. Deconectați în ordine inversă.
• Nu încercați să dezasamblați sau să reparați controlerul. Contactați personal calificat pentru service.
• Instalați controlerul într-o zonă bine ventilată, departe de materiale inflamabile.
• Although the controller has an IP67 waterproof rating, avoid submerging it in water or exposing it to extreme conditions beyond its operating temperature range.
• Asigurați-vă că sistemul voltage (12V or 24V) matches the controller's auto-detection capability and your battery bank.
• Use appropriate circuit breakers or fuses for the solar panel, battery, and load circuits.

4. Configurare și instalare

Instalarea corectă este crucială pentru performanța și longevitatea controlerului.

4.1 Schema electrică

Follow the wiring sequence carefully to avoid damage.

Figure 3: Wiring diagram illustrating connections for the solar panel, battery, and load.

Pași de cablare:

1. Conectați bateria: Connect the battery's positive and negative terminals to the corresponding battery connection leads on the controller. Ensure correct polarity. The controller will automatically detect the system voltage (12V sau 24V).
2. Conectați panoul solar: Connect the solar panel's positive and negative terminals to the corresponding solar panel connection leads on the controller. Ensure correct polarity.
3. Conectați sarcina: Connect the load's positive and negative terminals to the corresponding load connection leads on the controller. Ensure correct polarity.

Important: Always connect the battery first, then the solar panel, and finally the load. Disconnect in the reverse order: load, then solar panel, then battery.

4.2 Montare

The controller should be mounted in a location that allows for adequate air circulation. Refer to the dimensions below for installation planning.

Dimensiuni controler: 82mm (length) x 58mm (width) x 20mm (height).

5. Instrucțiuni de utilizare

The SRNE SL2410 controller is designed for user-friendly operation with its LED display and waterproof keys.

5.1 Indicarea stării LED

The controller provides visual feedback through its LED indicators:

5.2 Setări parametri

The controller allows for various parameter settings using the 'Mode' and 'Key' buttons. The power-down saving function ensures that your settings are retained even after power loss.

• Selectare tip baterie: The controller supports sealed, GEL, flooded lead-acid, ternary-material lithium, and lithium iron phosphate batteries. Refer to the controller's display and manual for specific steps to select the correct battery type.
• Load Working Modes: Up to 5 load working modes are available, facilitating application to different types of road lamps and monitoring devices. Consult the detailed product documentation for instructions on configuring these modes.
• Compensarea temperaturii: The external temperature sensor ensures accurate charging voltage adjustments based on ambient temperature, optimizing battery life.

6. Întreținere

The SRNE SL2410 is designed for low maintenance due to its robust IP67 rating and aluminum casing. However, periodic checks are recommended:

• Inspectați conexiunile: Periodically check all wiring connections for tightness and corrosion. Loose connections can cause voltagpicături de e și supraîncălzire.
• Curățați controlerul: While waterproof, ensure the controller's surface is clean from dust and debris to maintain optimal heat dissipation. Use a soft, dry cloth.
• Monitorizarea performanței: Observe the LED indicators regularly to ensure the system is operating normally.

7. Depanare

This section provides guidance for common issues. Refer to the LED Status Indication table in Section 5.1 for diagnostic help.

• Fără alimentare/Afișaj oprit: Check battery connections. Ensure the battery is charged above the controller's minimum operating voltage.
• No Charging (Charging LED off): Verify solar panel connections and ensure there is sufficient sunlight. Check for system over voltage (quick flashing Charging LED).
• Load Not Working (Load LED off): Check load connections. Ensure the battery is not under voltage (slow flashing Battery LED) or over-discharged (quick flashing Battery LED). Check for overload protection (slow flashing Load LED) or short-circuit protection (quick flashing Load LED).
• Battery Not Connected (Battery LED steady off): Recheck battery wiring and ensure secure connections.
• System Over Voltage (Charging LED quick flashing): Ensure the solar panel's open-circuit voltage nu depășește volumul maxim de intrare al regulatoruluitage.

If issues persist, consult the manufacturer or a qualified technician.
