• I-Smart 3-Stage Ukushaja: This battery charger charges the sub-battery from the starter battery using a 3-stage charging process (bulk, boost, float), ensuring optimal and automatic 100% charge.
• Main Battery Over-Discharge Protection: The DC-DC battery charger identifies whether the generator is running, preventing over-discharge of the starter battery and protecting the main battery.
• Ukuphepha Okuthuthukisiwe: Provides over-voltage protection, over-temperature protection, and reverse polarity protection, ensuring safe operation. It also isolates input and output to prevent voltage transmission errors and protect the house battery from overcharging.
• Idizayini Eqinile: Features a compact and robust construction for reliable performance.

2.2 Ubukhulu bomkhiqizo

The image above shows the Renogy DC-DC Charger with its dimensions: 31.1 cm length, 17.5 cm width, and 6.8 cm height.

2.3 Izingxenye Incazelo

This diagram illustrates the various ports and indicators on the Renogy DC-DC Charger.

3. Ukusetha nokufakwa

3.1 Umdwebo Wokuxhuma

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

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

3.2 Izilungiselelo zokushintsha kwe-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: Setha I-Float Charge Voltage
• I-S5: Set Charging Mode

3.3 Ukukhetha Usayizi Wekhebula

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. Ukusebenza

4.1 3-Stage Inqubo yokushaja

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

• Ubuningi: Charges the battery at the maximum current until it reaches a set voltage.
• Ukumuncwa: Izindleko ngevolumu engaguqukitage, reducing current as the battery approaches full charge.
• Ukuntanta: Maintains the battery at a constant, lower voltage to prevent self-discharge.

4.2 Izinkomba ze-LED

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

Qaphela: Inkomba yokushaja ingashintsha ngaphansi kwale mibandela elandelayo:

1. Okubomvu kuya Kuphuzi: Lapho ivolumutage ifinyelela ku-12.2V ngaphansi kwevolumutage ukululama.
2. Okuphuzi kuya Kubomvu: Lapho ivolumutage yehlela ku-12.0V ngaphansi kwevoltage isixwayiso.
3. Okuphuzi ukuya kokuluhlaza: A. Uma ifinyelela ku-voltage engaguqukitagisimo sokushaja, ukushaja kwamanje kuncane kuno-3A, kuhlala imizuzwana engama-30; B. Uma ijezi lokushaja lingaphezulu kuka-3A, ilokhu ishaja ize ifike kuvolthi engaguquki.tage state kanye nokwehla kwamanje ngaphansi kuka-3A, kuthatha imizuzwana engama-30.

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. Isondlo

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. Ukuxazulula izinkinga

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

• Awekho Amandla/Ama-LED Avaliwe: Check all battery connections and fuses. Ensure the starter battery voltage is above the cut-in threshold.
• Isikhombisi Sephutha Sivuliwe: Refer to the LED Indicators section (4.2) for the specific error type (over-voltage, over-temperature, reverse polarity, etc.) and take corrective action.
• Ibhethri Ayishaji: 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.

For persistent issues, please contact Renogy customer support.
