Renogy Bluetooth Module for RJ45/RS485 Solar Controllers — Black, BLE App Monitoring

The Renogy BT-2 Bluetooth Module lets you connect to Renogy devices with an RJ45/RS485 port to view and adjust system settings wirelessly through the DC Home app.

Designed as the newer-generation wireless interface for Renogy power components, the BT-2 replaces older dongles with broader compatibility across MPPT charge controllers, smart lithium batteries, inverters, and DC-DC MPPT chargers. It pairs with the Renogy DC Home mobile app (iOS and Android) to display live and historical performance metrics, change configuration options, and simplify system tuning without physically accessing each device. The module uses Bluetooth Low Energy (BLE) for steady, low-power communications and is optimized to run from the host device’s solar power supply.

How do I install and pair the BT-2 with my Renogy device?

Installation is plug-and-play: insert the BT-2 into the product’s RJ45 (RS485) communication port and then open the DC Home app to complete pairing. The app will guide you through detecting the module and linking it to the specific Renogy component, after which you can monitor or change settings over Bluetooth.

• Plug the module into the RJ45/RS485 port on the compatible device.
• Open Renogy DC Home app and follow the on-screen device discovery steps.
• Confirm pairing and assign the module to the correct system or controller.

What data and controls are available through the BT-2 and app?

The BT-2 relays both live and recorded metrics from the connected device, enabling you to check voltages, currents, state of charge, and power flow. The DC Home app also permits parameter adjustments—such as charge settings and operating modes—so you can fine-tune performance remotely.

• Live telemetry: voltage, current, power, and battery state information.
• Historical graphs for trend analysis and troubleshooting.
• Remote parameter edits like charge stages, system timing, and protection thresholds.

What is the wireless range and power behavior of the BT-2?

The BT-2 employs Bluetooth 4.2 with BLE to maintain a reliable link while minimizing energy draw. In typical conditions the module reaches up to about 82 feet (25 meters) line-of-sight, and because it draws minimal power and can be powered by the host system, it won’t significantly affect your solar setup’s energy budget.

• Bluetooth 4.2 and BLE ensure efficient, stable communications.
• Range up to roughly 82 ft (25 m) in clear line-of-sight scenarios.
• Ultra-low-power design allows sustained operation when connected to device power.

Which Renogy products are compatible with this Bluetooth module?

The BT-2 supports Renogy devices that expose an RS485 or RJ45 communication port, including many MPPT controllers, smart lithium battery models, inverters with communications, and DC-DC MPPT chargers. Check your product documentation or Renogy’s compatibility list to confirm port type and firmware requirements.

• Compatible with Rover Elite and other Renogy MPPT controllers having RS485 ports.
• Works with supported Renogy smart lithium batteries and compatible inverters.
• Also functions with Renogy DC-DC MPPT battery chargers that expose an RJ45/RS485 port.

Who is this for? The Renogy BT-2 is aimed at homeowners, RV and boat owners, off-grid installers, and DIY solar integrators who want easier, wireless access to system monitoring and configuration. If you prefer tuning settings from your phone, need quick diagnostics without tools, or maintain multiple Renogy components, the BT-2 streamlines everyday management while preserving low power use.
