Product Overview
Setup and Installation
Wiring Connections
The Renogy DC to DC Charger requires proper wiring to function correctly. Ensure all connections are secure and follow polarity guidelines.
Required Cables (Not Included)
- 4-gauge cables for connecting the starter battery and deep cycle battery to the charger.
- 16-gauge wire for the D+ signal cable.
Connecting the Charger
Connect the positive and negative terminals of your starter battery to the corresponding input terminals on the DC to DC charger. Similarly, connect the positive and negative terminals of your deep cycle (house) battery to the output terminals of the charger. Ensure all connections are tightened securely.
D+ Signal Connection
The D+ signal input is crucial for activating the charger. This input should be wired to a 12V source that becomes active when the vehicle's engine is running (e.g., ignition switch). This ensures the charger only operates when the alternator is providing power.
Optional Temperature Sensor
An optional temperature sensor (sold separately) can be connected to the RJ11 port. This sensor allows the charger to continuously adjust the charging voltage based on the battery temperature, optimizing charging efficiency and battery lifespan.
Battery Type Selection (DIP Switches)
The charger features DIP switches to select the appropriate battery type for your deep cycle battery. Refer to the table below for the correct switch settings based on your battery chemistry.
| Battery Type | DIP Switch 1 | DIP Switch 2 | DIP Switch 3 | DIP Switch 4 | DIP Switch 5 |
|---|---|---|---|---|---|
| Lithium (LiFePO4) | ON | ON | OFF | OFF | OFF |
| AGM | OFF | ON | OFF | OFF | OFF |
| Gel | ON | OFF | OFF | OFF | OFF |
| Flooded | OFF | OFF | OFF | OFF | OFF |
Ensure the correct battery type is selected to prevent damage to your battery and ensure optimal charging performance.
Operating Instructions
Once the charger is correctly installed and the battery type is set, the unit is ready for operation.
Automatic Charging
The Renogy DC to DC Charger automatically begins charging the deep cycle battery when the vehicle's engine is running and the D+ signal is active. The power indicator LED on the charger will illuminate green, indicating that the charger is on and actively charging.
Multi-Stage Charging
The charger utilizes a 3-stage charging algorithm (Bulk, Boost, and Float) to ensure your deep cycle battery is charged optimally and automatically to 100% capacity, prolonging its lifespan.
Protection Features
The charger is equipped with various protection features for safe operation, including Over-voltage Protection, Over-temperature Protection, and Reverse Polarity Protection. These features safeguard both the charger and your batteries.
Maintenance
Regular maintenance ensures the longevity and optimal performance of your Renogy DC to DC Charger.
- Periodically inspect all wiring connections to ensure they are secure and free from corrosion.
- Keep the charger's ventilation fans and grilles clear of dust and debris to ensure proper airflow and prevent overheating.
- Clean the exterior of the charger with a dry, soft cloth. Do not use harsh chemicals or abrasive cleaners.
- If an optional temperature sensor is used, ensure it remains securely attached to the battery and is not damaged.
- Store the charger in a dry, well-ventilated area when not in use for extended periods.
Troubleshooting
This section addresses common issues you might encounter with your Renogy DC to DC Charger.
| Problem | Possible Cause | Solution |
|---|---|---|
| Charger not turning on (Power LED off) | No D+ signal; Loose wiring; Blown fuse; Low starter battery voltage. | Check D+ signal connection to ensure it's active when the engine is running. Verify all wiring connections are secure. Check inline fuses on both input and output lines. Ensure starter battery voltage is above the minimum operating threshold. |
| Fault LED illuminated | Over-temperature; Over-voltage; Reverse polarity. | Check for obstructions around ventilation fans. Allow unit to cool down. Verify input/output voltages are within specifications. Recheck wiring for correct polarity. |
| Battery not charging optimally | Incorrect battery type setting; Faulty temperature sensor (if used); Undersized cables. | Verify DIP switch settings match your battery type. Check temperature sensor connection and function. Ensure cable gauge is sufficient for the current draw. |
