Renogy 500A Combiner Box (Communication Version), 12V-48V Smart Battery Distribution Hub with Bluetooth and CANbus

The Renogy 500A Combiner Box (Communication Version) is a heavy-duty, space-efficient power distribution hub designed for sophisticated electrical systems in RVs, boats, and off-grid cabins. Acting as a central junction, it consolidates multiple high-power connections—such as batteries, inverters, and charge controllers—into one secure, fused location.

This "Communication Version" (Model: REC500CB-98CM) is distinguished by its built-in Bluetooth and CANbus ports, allowing it to integrate seamlessly into the Renogy ecosystem for real-time monitoring and smart power management through the Renogy DC Home app.

Key Features

• High-Current 500A Busbars: Features two heavy-duty tinned copper busbars (positive and negative) capable of handling a continuous 500A current, ideal for systems with large 3000W+ inverters.

• Integrated Communication: Equipped with built-in Bluetooth and CANbus/Modbus ports, enabling users to monitor system performance and circuit status remotely via smartphone or a Renogy ONE gateway.

• Streamlined Wiring: Consolidates all main electrical connections into a single location, significantly reducing cable clutter and simplifying the troubleshooting process.

• Enhanced Safety & Protection: Designed for use with high-security fuses (such as MRBF or ANL) to protect each individual circuit from overcurrent and short circuits.

• LED Status Indicators: Features on-board LED lights that accurately indicate the electrical connection status of each port, aiding in rapid visual diagnostics.

• Expandable Design: Includes extended terminals that allow for the easy addition of another combiner box, enabling the system to scale as your power needs grow.

• Rugged All-Weather Housing: Encased in a durable, powder-coated sheet metal enclosure with an IP22 rating, protecting internal components from dust and minor splashes.
