Professional shunt for high current systems
This 1000A/50mV shunt is an ideal choice for accurate current and power measurement in high-performance DC systems. A reliable solution for solar systems, RVs, battery banks on boats, uninterruptible power supplies, and industrial power distribution systems. With this device, the charging and discharging processes can be tracked in detail, preventing problems arising from battery overload or deep discharge.
Main features and benefits
- Maximum measurable current: 1000 A under continuous load
- Voltage drop: 50 mV at nominal load
- Low-loss current measurement with high accuracy
- Compatible with DC measuring instruments, battery monitors, and controllers
- Robust mechanical design, high current connectors
- Suitable for 12 V, 24 V, 48 V, and higher voltage DC systems (with appropriate insulation and design)
How does the shunt work?
The shunt is a special low-resistance resistor that creates a proportional voltage drop to the current flowing through it. The 50 mV output signal can be safely measured by a battery monitor, DC ammeter, or data collection device. This allows for precise monitoring of the system's load, consumption, charging, and discharging currents.
The 1000 A load capacity means that the shunt can continuously handle such a large current while the generated heat and voltage drop do not adversely affect the system's operation. The 50 mV nominal voltage drop minimizes energy loss and does not cause significant voltage reduction between the battery and the consumers.
Applications
- Monitoring battery-side current in solar systems and hybrid inverters
- Monitoring energy supply in RVs, caravans, off-grid systems
- Monitoring onboard battery banks of sailing and motor boats
- Current monitoring in industrial DC power supplies, uninterruptible systems (UPS)
- Protection and monitoring of high current DC consumers – winches, inverters, compressors
Why is accurate current measurement important?
The lifespan of batteries and the reliability of the entire energy supply system are significantly influenced by how accurately we know the current consumption and charging processes. With the shunt:
- the actual consumption can be calculated,
- the battery's state of charge (SoC) can be determined,
- overloads and faulty consumers can be detected in time,
- solar charging control and inverter usage can be optimized.
Installation and connection
The shunt is generally advisable to be inserted into the negative wire of the battery so that all consumers and charging currents flow through it. This way, the ammeter or battery monitor gets a complete picture of the entire system's energy flow.
- Choose appropriate cross-section cables for the expected maximum current.
- Place the shunt near the battery in a well-ventilated, safe location.
- Connect the negative cables from the battery and consumers/inverter to the high current screw terminals.
- Connect the thin measuring wires (for the 50 mV signal) to the appropriate input of the DC measuring instrument or battery monitor.
- Check the tightness of the connections, polarity, and secure, vibration-free mounting.
Safety and installation considerations
- Always perform installation on a de-energized system, avoiding short circuits.
- Use appropriately sized fuses and circuit breakers in the system.
- Ensure proper insulation and mechanical protection (cable conduits, terminals, conduit cables).
- Regularly check the tightness of screw connections, especially in high current systems.
