Understanding the Victron Smart Shunt Wiring Diagram
The Victron Smart Shunt wiring diagram provides a clear map of how to connect the device to a battery and its load. The diagram typically illustrates connections for the battery negative terminal, load negative terminal, and any auxiliary devices. Correct placement of the shunt in the negative line of the battery ensures that all current entering or leaving the battery is measured accurately. Positive connections usually bypass the shunt, connecting directly to the battery positive terminal. Understanding each terminal and wire in the diagram is crucial to avoid installation errors that could result in incorrect readings or potential damage to the shunt and battery system.
Step-by-Step Wiring Guide
Following the wiring diagram, the installation process of the Victron Smart Shunt involves several key steps
- Identify the negative terminal of the battery where the shunt will be connected.
- Connect the main negative battery cable to the Battery terminal on the shunt.
- Connect the load or inverter negative cable to the Load terminal on the shunt, ensuring all current leaving the battery passes through the shunt.
- Verify that the positive battery connections bypass the shunt and go directly to the load or system bus.
- Power on the system and pair the Smart Shunt with the VictronConnect app via Bluetooth or connect through VE.Direct for monitoring.
- Confirm proper operation by checking voltage, current, and amp-hour readings in the app or on connected display devices.
