Renogy BT-2 Bluetooth Module for Solar Systems | Wireless Monitoring & RS485/RJ45

Overview

The Renogy BT-2 Bluetooth Module adds a compact, rugged wireless link to your solar setup. Using Bluetooth 4.2/BLE, it connects with the Renogy DC Home App (iOS/Android) to deliver real-time data, historical logs, and remote control options. This enables you to observe how your system behaves in daily use—without digging through screens or chasing cables.

Real-time visibility with long-range flexibility

Track solar generation, battery voltage, and inverter status from a comfortable distance. With an 82 ft (25 m) signal range and no mandatory line-of-sight, you can place the module where it makes sense for your space—whether that’s an RV cabinet, a marine bulkhead, or a roof hatch for quick checks. The app stores historical data, so you can review trends and adjust settings on your schedule.

• Real-time data at a glance for array, storage, and power device health
• Wireless range up to 82 ft (25 m) supports flexible placement
• iOS/Android app with historical logs and remote configuration

Rugged, low-power design for demanding environments

The BT-2 draws power from the RJ45 port, topping standby consumption at about 0.04 W. Its IP54-rated housing helps resist dust, rain, and humidity, making it suitable for outdoor sheds, desert installations, or cabin rooftops. It operates across a wide temperature span, so you can rely on steady performance in extreme climates.

• Ultra-low standby power for solar-powered sites
• IP54 weather resistance protects against dust and moisture
• Operates from -20°C to 85°C (-4°F to 185°F) for varied climates

Plug‑and‑play with Renogy RS485 devices

Instantly connect to Renogy Rover Elite MPPT controllers, smart lithium batteries, and pure sine wave inverters via RS485. No wiring or complex setup is required—just plug the BT-2 into the device’s RJ45 port and begin controlling charging stages, inverter power-saving modes, and dual DC-DC chargers from your phone.

• Seamless RS485 integration with Rover Elite MPPT controllers and other devices
• Control charging stages, inverter modes, and DC-DC charging from the app
• Simple, cable-friendly installation with RJ45 port power

Smart alerts, multi-device management, and scalable systems

Set custom battery voltage alerts and optimize energy flow across different chemistries. The Renogy DC Home App supports managing multiple devices from a single dashboard and storing performance logs to share with technicians or teammates. The BT-2 is designed to scale for larger solar arrays through RS485 daisy-chaining and meets FCC/ISED standards for safe operation near users. A 16.4 ft communication cable is included to simplify placement on boats, tiny homes, or off-grid cabins.

• Custom battery alerts and centralized, multi-device control
• 30-day performance reports for troubleshooting and optimization
• RS485 daisy-chaining supports expanding systems
