3. Configuració i instal·lació

3.1 Diagrama de connexió

This diagram illustrates the wiring connections for the DC-DC Charger in a typical RV setup, connecting to both the main (starter) battery and the sub-battery (house battery).

• DC-DC Charger ↔ Main Battery Wiring
• DC-DC Charger ↔ Sub-battery Wiring
• DC-DC Charger D+ Port ↔ Alternator D+ Terminal Wiring

Nota: All wiring requires separate purchase. Cables are not included with this product; please prepare them separately if needed.

3.2 Configuració del commutador DIP

The image shows the DIP switches used to configure the charger. By operating the 5 switches (S1-S5), you can adjust the battery type and charging voltage.

• S1 and S2: Set Absorption Voltage
• S3 and S4: Estableix el volum de càrrega flotanttage
• S5: Set Charging Mode

3.3 Selecció de la mida del cable

Refer to this table for recommended cable sizes and fuse ratings based on your specific DC-DC charger model and cable length.

3.4 D+ and LC Ports

The image highlights the D+ and LC ports on the charger.

• D+ Port: Connects to the alternator's D+ terminal for smart alternator detection.
• LC Port: By connecting to the LC port, the charging current can be limited by half. (Recommended cable size: 0.75～1.2SQ)

4. Funcionament

4.1 3-Stage Procés de càrrega

The graph above illustrates the 3-stage charging process (Bulk, Absorption, Float) that fully charges the battery.

• A granel: Charges the battery at the maximum current until it reaches a set voltage.
• Absorció: Charges at a constant voltage, reducing current as the battery approaches full charge.
• Flotador: Maintains the battery at a constant, lower voltage to prevent self-discharge.

4.2 Indicadors LED

The charger features LED indicators to communicate the charging status and battery type. Refer to the tables below for detailed explanations.

Nota: L'indicador de càrrega pot canviar en les condicions següents:

1. De vermell a groc: quan el voltage arriba a 12.2V sota voltage recuperació.
2. De groc a vermell: quan el voltagcau a 12.0V sota voltage advertència.
3. De groc a verd: A. Quan arriba al vol constanttagEn estat de càrrega, el corrent de càrrega és inferior a 3A i dura 30 segons; B. Quan el corrent de càrrega és superior a 3A, es continua carregant fins que arriba al vol constanttagL'estat i el corrent cauen per sota de 3A, dura 30 segons.

4.3 Alternator Type and Starting Battery Voltage

4.4 Charging Current Distribution (Solar + Alternator)

When using both solar and alternator inputs, the current is split. For example, the RBC30DIS model will provide 15A from solar and 15A from the alternator, totaling 30A.

5. Manteniment

Regular maintenance ensures optimal performance and longevity of your Renogy DC-DC Charger.

• Periodically check all wiring connections for tightness and corrosion. Clean any corroded terminals.
• Inspect the charger for any physical damage or signs of overheating.
• Ensure the area around the charger is free from dust and debris to maintain proper ventilation.
• Verify that the battery type settings are correct for your installed batteries.

6. Solució De Problemes

If you encounter issues with your DC-DC Charger, refer to the following basic troubleshooting steps:

• Sense alimentació/LED apagats: Check all battery connections and fuses. Ensure the starter battery voltage is above the cut-in threshold.
• Error Indicator On: Refer to the LED Indicators section (4.2) for the specific error type (over-voltage, over-temperature, reverse polarity, etc.) and take corrective action.
• La bateria no es carrega: Verify that the correct battery type is selected using the DIP switches. Check solar panel connections and output, and ensure the alternator is functioning correctly.
• Reduced Charging Current: Ensure the LC port is not connected if full current is desired. Check cable sizes against recommendations in section 3.3.
