Xantrex Remote Battery Temperature Sensor

The Xantrex Remote Battery Temperature Sensor is a precision monitoring device designed for off-grid solar systems, RV installations, marine applications, and backup power setups where accurate temperature compensation is critical. This sensor communicates with Xantrex chargers and charge controllers to optimize charging performance in fluctuating environmental conditions. Whether you're managing a battery bank in an extreme climate or maintaining peak charging efficiency in variable temperatures, this remote sensor ensures your system adapts intelligently to ambient conditions.

The sensor operates by continuously monitoring the battery installation's ambient temperature and transmitting real-time data to your Xantrex charge controller or battery charger. The controller then automatically adjusts output voltage to compensate for temperature variations—raising voltage in cold conditions to achieve full charge and reducing it in heat to prevent overcharging and battery damage. This temperature-compensated charging extends battery lifespan significantly and improves cycle efficiency. The compact design (5 x 6 inches) and lightweight construction (0.25 lbs) make installation straightforward in any battery enclosure or mounting location near your battery bank.

This remote sensor is ideal for users operating battery systems in environments with significant temperature swings—deserts, northern climates, or sealed battery compartments where temperature gradients vary from ambient air. Technicians and system designers rely on temperature-compensated charging to maximize lithium, AGM, and lead-acid battery performance and warranty compliance. Installation requires a compatible Xantrex charger or charge controller with temperature sensor input capability; verify your model supports remote temperature compensation before purchase. The sensor's durable construction and simple wired interface ensure reliable operation for years in demanding off-grid and mobile power applications.
