Battery Monitors, Shunts and Accurate State of Charge
Battery Monitors, Shunts and Accurate State of Charge
Intro
Knowing your true state of charge prevents surprises off-grid. A proper shunt monitor is the most reliable way to track LiFePO4 usage.
Why Use a Shunt Monitor
- Accuracy - measures real current flow in and out of the battery.
- History - tracks daily usage, charge cycles and trends.
- Alerts - set thresholds for low state of charge or high load.
Setup Tips
- Install the shunt in the main negative so all loads and chargers pass through it.
- Calibrate to your battery bank capacity and sync after a full charge.
- Keep sense wires short and secure.
What App or Display Data Matters
- State of charge for the quick glance.
- Current and power to see real-time draw or charge.
- Daily Ah or Wh to plan solar and driving time.
Bottom line
A shunt-based monitor gives confidence day to day and helps diagnose issues before they become problems.
Pair your lithium battery with a quality monitor
