RENOGY REGO Bluetooth Module for Rover MPPT & DC-DC Chargers — RJ45/RS485, 82 ft Range, IP54

RENOGY REGO BT-2 is a plug-and-play Bluetooth communication module that wirelessly connects compatible new-generation Rover MPPT controllers and Renogy DC-DC chargers to the DC Home App for live system monitoring and configuration.

The BT-2 replaces fumbling with cables and repeated trips to controller displays by bringing real-time solar and battery data to your smartphone from up to 82 feet (25 meters). Designed for the current Rover series and Renogy DC-DC chargers with an RJ45/RS485 port, this compact module powers itself from the device it plugs into and includes a 5 m RJ45 extension cable to provide flexible mounting options inside vans, boats, cabins, and solar arrays.

How do I know the BT-2 will fit my controller or charger?

Check the communication socket on your Renogy product before ordering. The BT-2 is built for equipment that uses an 8‑pin RJ45 communication port and the RS485 protocol. If your device has a 6‑pin RJ12 port, order the legacy BT-1 instead.

• Compatible with Rover MPPT 20A/30A/40A/60A/100A new-gen models.
• Works with Renogy DC-DC chargers that use RS485 via RJ45.
• Not compatible with devices that require a BT-1 (RJ12/6‑pin).
• Inspect the controller’s communication port before purchase.

What information can I monitor and change from the DC Home App?

The DC Home App provides live readings and adjustable settings so you can track performance and protect batteries without physical access to the device. Use the app to view input and output metrics, and to tweak charge parameters for better battery health.

• Real-time solar input wattage, battery voltage, and charge/discharge current.
• Inverter load monitoring and historical trend logging on supported devices.
• Adjustable charging profiles for LiFePO4, AGM, Gel, and Flooded batteries.
• Set high/low voltage alerts to avoid deep discharge or overcharge events.

How simple is installation and where can I place the module?

Installation is a true plug-and-play experience — insert the BT-2 into the RJ45 port and pair with the DC Home App. The module draws minimal standby power and includes a 16.4 ft (5 m) RJ45 extension cable so you can mount it where reception and convenience are best.

• Plug directly into the RJ45/RS485 communication port; no wiring required.
• Includes 5 m RJ45 extension for flexible placement inside cabinets or engine bays.
• Rated IP54 for dust and splash protection; temperature rated -20°C to 85°C.
• Bluetooth range up to 25 m (82 ft) in open areas; performance varies with obstacles.

How does the BT-2 help extend battery life and system uptime?

By letting you monitor system behavior and adjust charge settings remotely, the BT-2 helps you prevent damaging cycles and respond to issues before they escalate. Timely alerts and tailored charge profiles reduce stress on batteries and improve overall system efficiency.

• Fine-tune charging voltages and charging stages to match battery chemistry.
• Create custom alert thresholds to act on low-voltage or high-voltage events.
• Track charge/discharge cycles and identify abnormal loads or parasitic draws.
• Minimizes unnecessary site visits to check system status.

Who is this for: The BT-2 is ideal for RVers, marine owners, off-grid homeowners, and installers who use Renogy’s new-generation Rover MPPT controllers or RS485-enabled DC-DC chargers and want remote visibility and control. If you need wireless access to live solar and battery data, convenient app-based configuration, and a durable module that fits behind panels, in engine compartments, or inside battery enclosures, the BT-2 makes monitoring fast and simple. Before purchasing, confirm your device uses an 8‑pin RJ45 communication port (not the 6‑pin RJ12) to ensure compatibility.
