Renogy Battery Shunt 300 with the Built-in Bluetooth

Renogy Battery Shunt 300 with Built-in Bluetooth

The Renogy Battery Shunt 300 is an intelligent battery monitor that measures your battery’s voltage and current, and uses that data to calculate the state of charge (SOC) and remaining running time. It also records historical charging and discharging data — including full deep-discharge cycles, discharge capacity, charge cycles, and battery temperature — giving you a complete picture of your battery bank’s health and performance.

With its built-in Bluetooth module, the Shunt 300 communicates with the DC Home app and Renogy ONE, letting you monitor real-time charge and discharge data and customise key parameters from your phone — including nominal capacity, deep-discharge thresholds, temperature alarms, and SOC alarms.
