Morningstar RTS Remote Temperature Sensor, Replacement with 12 Month Warranty & USA Business

Improve battery temperature monitoring and solar charging performance with the Wholesale Sensors PTS29-0 Replacement for Morningstar RTS Remote Temperature Sensor. Engineered as a perfect OEM-style replacement, this remote temperature sensor is designed to provide dependable battery temperature feedback to compatible Morningstar solar charge controllers. It is an ideal replacement when the original RTS has become damaged, worn, or unreliable.

The Morningstar RTS Remote Temperature Sensor is used to measure temperature directly at the battery. This temperature information allows a compatible solar charge controller to adjust its charging behavior based on actual battery temperature instead of relying only on the temperature measured at the controller. Morningstar recommends using an RTS when battery temperature can differ from controller temperature by more than 5°C or 9°F. Morningstar Corporation

Compatible Morningstar Solar Charge Controllers

This replacement is designed for compatible Morningstar controllers that support the RTS Remote Temperature Sensor. Documented applications include TriStar, TriStar MPPT, TriStar MPPT 600V, ProStar, ProStar MPPT, SunSaver MPPT, EcoBoost MPPT, SunKeeper, SunSaver Duo, and EcoPulse controllers. Morningstar Corporation

Compatibility is based on the solar charge controller rather than a vehicle make, model, or year. Always verify that your specific controller is designed to accept the Morningstar RTS before installation.

Accurate Temperature-Compensated Battery Charging

Battery temperature can change significantly depending on weather, installation location, enclosure design, operating conditions, and charging activity. When the battery and solar controller are installed in different locations, their temperatures may also be substantially different.

The RTS solves this problem by measuring temperature at the battery itself. The controller can then use that information for more accurate temperature-compensated charging. Morningstar states that its RTS improves battery charging by providing direct battery temperature information and can help promote efficient charging performance. Morningstar Corporation

This makes a functioning remote temperature sensor particularly valuable for off-grid solar systems, battery banks, RV solar installations, cabins, telecommunications equipment, backup power systems, and other renewable energy applications where battery temperatures can vary throughout the year.

Designed for Battery-Mounted Temperature Monitoring

The RTS sensor is installed directly at the battery so it can measure battery temperature rather than surrounding controller temperature. Morningstar installation instructions specify securing the sensor lug to a battery terminal and routing the temperature sensor wiring to the compatible charge controller. The sensing connection is electrically isolated, and Morningstar documentation notes that the sensor should not be placed inside a battery cell. Amazon S3

Depending on the compatible controller, installation procedures can vary. Some controllers use dedicated remote temperature terminals, while other configurations may require a different connection method. Always follow the service and installation instructions for your specific Morningstar controller.

Helps Restore Proper Charging Compensation

A damaged remote temperature sensor can prevent the controller from receiving accurate battery temperature information. Depending on the controller and system configuration, this may affect temperature compensation and charging performance.

Replacing a confirmed faulty RTS can help restore accurate battery temperature feedback and allow the compatible controller to adjust charging according to actual battery conditions.

The sensor itself should not automatically be assumed to be the cause of every battery charging problem. If charging performance remains abnormal, inspect the battery condition, battery connections, controller settings, solar array, wiring, fuses, charging configuration, and controller operation.

This component does not use automotive OBD-II diagnostic trouble codes.

Reliable Wholesale Sensors Replacement

Wholesale Sensors designs replacement sensing components for customers who need dependable alternatives to original equipment parts. The PTS29-0 Remote Temperature Sensor is built for reliable temperature monitoring and is rigorously tested for sensing response, electrical performance, consistency, continuity, and dependable operation.

The sensor is intended to perform the same essential function as the compatible Morningstar RTS by providing battery temperature information to the solar charge controller.

Solar and Off-Grid Applications

The replacement RTS is suitable for compatible Morningstar-controlled solar power systems used in residential solar installations, RV and camper systems, marine and remote power applications, cabins, battery backup systems, telecommunications equipment, industrial battery systems, and off-grid renewable energy installations.

For systems where the battery bank and controller experience different ambient conditions, direct battery temperature monitoring can provide the controller with more useful temperature information than relying only on controller temperature.

12-Month Warranty
