The Renogy Battery Shunt 300 is an intelligent battery monitoring device designed to help you precisely track and manage the performance of your battery bank. Installed inline with your battery, it measures current flow and voltage to calculate real-time State of Charge (SOC), temperature, and voltage data. Paired with compatible Renogy systems like the Renogy ONE Core and the DC Home app, it provides deep visibility into battery usage and health — making it perfect for solar systems, RV and marine setups, off-grid power systems, and backup battery arrays.
Accurate Battery Monitoring: Tracks charge and discharge currents up to 300 A continuous with high precision (±1 %).
Bluetooth Connectivity: Built-in Bluetooth LE and BLE Mesh enable real-time monitoring via the Renogy ONE Core and DC Home smartphone app.
Measures Key Metrics: Displays State of Charge, voltage, current, and temperature for smarter battery management.
Compatible With Multiple Battery Types: Works with lead-acid (AGM, GEL), LiFePO₄, lithium-ion, and NiMH battery chemistries.
Historical Data Logging: Records past charge/discharge cycles and performance data to help optimize system workload.
Compact & Durable: Rugged construction designed for long-term use in solar, RV, marine, and off-grid environments.
Simple Surface Mounting: Install in minutes — place on top of the battery or mount on a wall/board using the included screws.
Easy Connections: Connect the shunt between the battery negative terminal and system load or charge controller using the supplied B+ wires and M10 bolt connections.
Temperature Sensor Included: The shunt comes with a battery temperature sensor (1.5 m) to help monitor and adjust for thermal effects on performance.
Bluetooth Pairing: Pair with the Renogy ONE Core or DC Home app for remote monitoring. Setup involves a few simple steps and is designed to be user-friendly.
No Display Needed: All monitoring and data display is done via Bluetooth to your phone or compatible monitoring device.
