Battery Voltage Sensor Quick Guide
Model: RVSCC
Battery Voltage Sensor (Model: RVSCC)
The Battery Voltage Sensor (BVS) provides users with more accurate battery charging, ensuring that the charge controller operates as effectively as possible. In applications with long line runs, there can be a voltage difference between the charge controller's terminals and the battery terminals. The BVS is the ideal solution, delivering a more accurate battery voltage reading to the controller. This allows the controller to adjust its charging stages more precisely, ultimately extending your battery life. The BVS features a housing connector that easily connects to most Renogy Flagship MPPT and PWM charge controllers, offering a simple, plug-and-play solution for your system.
The RVSCC is shipped with a small green terminal block and two wires with ring terminals. It is compatible with charge controllers that have a battery voltage sensor port, typically marked with a "BATT" label and indicating polarity with "+" or "-".
Compatible Chargers
The following chargers are compatible with the RVSCC. These chargers will have a "BATT+/-" port, a "Battery Sampling" text near the port, or a "BVS" label.
Note: This list will expand as more products are introduced to the market.
- Rover Elite 20A (Model: RCC20RVRE)
- Rover Elite 40A (Model: RCC40RVRE)
- Rover Li 60 (Model: RNG-CTRL-RVR60)
- Rover Li 100 (Model: RNG-CTRL-RVR100)
- DCDC w/MPPT (Model: RBC50D1S-G1)
Identifying the Port:
- Renogy Rover Elite displays a "BATT" port.
- Renogy Rover Li displays a "Battery Sampling" port.
- Renogy DCDC w/MPPT displays a "BVS" port.
Color Scheme
The RVSCC has one positive lead and one negative lead that correspond to the battery's positive and negative connections. The following indicates the polarity for the color scheme:
| Positive (+) | Negative (-) |
|---|---|
| Red | Black |
| Brown | Blue |
Connecting RVSCC to Charger
WARNING: Polarity is critical when connecting the battery voltage sensor to the corresponding port.
- Identify the Battery Voltage Sensor Port on your charge controller. Verify the correct polarity using the silk print on the device, the user manual, or the specification sheet.
- Position the green terminal block with the wire hatches facing you. Loosen the terminal block screws on top by rotating them counterclockwise. Ensure the wire hatch is completely open.
- Connect the positive pin from the RVSCC to the positive terminal (left side in the example) of the green terminal block and tighten the screw clockwise to secure the wire. Repeat this process for the negative connector (right side in the example).
- Once the wires are secured in the terminal block, connect the ring terminals of the battery voltage sensor to the respective positive (+) and negative (-) terminals on your battery.
- Connect the green terminal block directly to the battery voltage sensor port on the charge controller.
- Verify a successful connection. Ensure the green connector is firmly seated in the port, or use a multimeter to read the voltage at the respective battery terminals connected to the screws.
