Renogy Battery Shunt 300 – Remote Monitoring, 8V-120V, Up to 500A

Overview

The Renogy Battery Shunt 300 is a high-precision current sensor designed to give you a clearer picture of your battery bank. Built for versatility, it works across a range of chemistries and setups, from small portable systems to larger off-grid configurations. It’s crafted to help you monitor energy flow with confidence, so you can plan usage and maintenance with a calmer, data-informed approach.

Key Benefits

• Broad battery compatibility includes starter and main batteries such as lead-acid (AGM, GEL), LiFePO4, Li-ion, and Ni-MH, letting you consolidate monitoring for diverse packs.
• Real-time and historical data capture keeps you informed about current conditions and energy trends, helping you spot anomalies before they become issues.
• Remote monitoring and control are possible via Renogy ONE and the DC Home App using Bluetooth, enabling off-site visibility and occasional adjustments.

Real-World Use Cases

In RVs, boats, cabins, or home solar setups, the shunt helps you track charging and discharging cycles, informing routine checks and optimizing leaf-units or storage strategies. The device’s sensitive readings can support data-driven decisions about inverter use, generator timing, and battery health awareness.

• Real-time readings paired with historical logs enable you to compare season-to-season performance.
• Bluetooth-enabled remote access supports quick checks during trips or away from the battery chamber.

Safety, Temperature, and Data

A built-in battery temperature sensor adds a layer of safety and efficiency by correlating temperature with performance metrics. Temperature-aware data can guide charging strategies and long-term efficiency without asserting guarantees.

Specifications and Compatibility

• Operating range spans 8V to 120V with support for currents up to 500A, making it suitable for a variety of vehicle and off-grid systems.
• Designed to work with a wide array of battery chemistries, reducing the need for multiple sensors in a single setup.

Note: Not compatible with Renogy ONE M1 at this time.
