Victron Type C Temperature Sensor for Inverter RS Smart Solar and MPPT RS

Precision Battery Temperature Monitoring for Victron RS Series Inverters and Charge Controllers

The Victron Type C Temperature Sensor (ASS000020000) is a dedicated spare or replacement sensor engineered for the Victron Inverter RS Smart Solar and Victron MPPT RS charge controllers. It provides direct battery temperature data to your inverter or charge controller, enabling voltage compensation based on actual battery temperature. This is essential for maintaining battery health, optimising charge efficiency, and extending service life in demanding off-grid, backup, and mobile power systems.

Unlike generic sensors, this Victron Type C sensor is purpose-built for the RS series, ensuring seamless integration and reliable data transmission. It features a robust ring terminal for secure attachment to the battery terminal, a durable twin-core cable, and pre-crimped wire ferrules for quick, error-free connection to the inverter or MPPT RS unit. The clear identification tag helps confirm correct application during installation or maintenance.

Why Accurate Temperature Sensing Matters

Battery chemistry is highly sensitive to temperature. Charging a lead-acid or lithium battery without temperature compensation can lead to undercharging in cold conditions or overcharging in hot conditions, both of which accelerate degradation and reduce usable capacity. By connecting this sensor directly to the battery terminal, the Inverter RS Smart Solar or MPPT RS can adjust charge voltages in real time, protecting your investment and ensuring consistent performance across a wide range of operating temperatures.

Key Features

• Direct battery terminal temperature sensing for precise voltage compensation
• Pre-crimped wire ferrules for secure, tool-free insertion into RS series terminals
• Durable twin-core cable with colour-coded red and black insulation for easy polarity identification
• Ring terminal lug for reliable thermal contact at the battery post
• Clear identification tag with part number for quick verification
• Compatible with Victron Inverter RS Smart Solar and MPPT RS models
• Cable length can be extended if required, offering installation flexibility

Designed for Reliable Integration

This sensor is not a VE.Smart Networking device and does not transmit temperature data to VRM independently; it connects directly to the dedicated sensor input on the Inverter RS Smart Solar or MPPT RS. This wired connection ensures a stable, interference-free signal path, which is critical in electrically noisy environments such as engine rooms, inverter compartments, or industrial installations. The factory-crimped ferrules eliminate the need for field termination, reducing installation time and the risk of poor connections.

Installation and Compatibility

The Victron Type C Temperature Sensor is a direct replacement for the sensor supplied with the Inverter RS Smart Solar and is also compatible with the MPPT RS. Installation is straightforward: attach the ring terminal to the battery negative terminal (or positive if specified in your system design), route the cable to the inverter or charge controller, and insert the ferrules into the designated sensor terminals. The cable can be extended using appropriate gauge wire and connectors if the standard length is insufficient for your layout.

Protect Your Battery Investment

Whether you are commissioning a new Victron RS system or replacing a damaged sensor, the genuine Victron Type C Temperature Sensor ensures your battery charging remains accurate and safe. Avoid the risks of generic sensors that may not provide the correct resistance curve or mechanical fit. Choose the component designed and tested by Victron for optimal compatibility and long-term reliability.
