It measures temperature at the battery and the controller uses this data for very accurate temperature compensation. - HIGH ACCURACY: This sensor is essential when the battery temperature differs by more than 5°C (9°F) from the controller, ensuring accurate temperature compensation for improved battery charging. Provides precise temperature readings maintaining reliable performance across a wide temperature range. - DURABLE & PROTECTION: For defense against harsh environments, the sensor is securely encapsulated in epoxy within a robust power lug housing. This durable construction protects against lightning surges and short circuits for long-lasting performance and reliability in the most challenging conditions. - CONTROLLER COMPATIBILITY: The RTS is compatible with various Morningstar models including SunSaver MPPT, TriStar MPPT, SunKeeper, SunSaver Duo, and ProStar. The TriStar has no on-board temperature compensation thus requiring the use of the RTS. Other Morningstar controllers will default to an on-board temperature sensor if a RTS is not connected. - TRUSTED RELIABILITY: Morningstar Corporation is a US company established in 1993 and is a global leader in manufacturing PWM and MPPT solar charge controllers, inverters, and accessories. Renowned for the industry's lowest hardware failure rate, Morningstar provides dependable, innovative technology for advanced solar applications. Morningstar products include U.S. based Tech Support and are the top choice for mission-critical users. - The RTS is compatible with SunSaver MPPT, SunSaver Duo, SunKeeper, and all ProStar and Tristar controller models - The RTS is protected from lightning surges and short circuits. - The sensor is encapsulated in epoxy inside a power lug housing for maximum protection from harsh environments, - Five year warranty ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0072P8T9U | | Best Sellers Rank | #756,273 in Automotive ( See Top 100 in Automotive ) #1,398 in Automotive Replacement Coolant Temperature Sensors #30,303 in Automotive Replacement Engine Cooling & Climate Control | | Brand Name | Morningstar Corporation | | Customer Reviews | 4.8 4.8 out of 5 stars (82) | | Included Components | Controller | | Item Dimensions | 5.3 x 5.7 x 2 inches | | Item Weight | 3.2 ounces | | Manufacturer | Morningstar Corporation | | Material Type | Metal | | Model | RTS | | Number of Items | 1 | | Part Number | RTS | | Specific Uses For Product | battery temperature monitoring in solar systems | | UPC | 102309368277 | | Unit Count | 1 Count | | Warranty Description | 5 Years | ## Product Details - **Brand:** Morningstar Corporation - **Item Weight:** 3.2 ounces - **Item dimensions L x W x H:** 5.3 x 5.7 x 2 inches - **Material:** Metal - **Specific Uses For Product:** battery temperature monitoring in solar systems ## Images ![Morningstar Remote Temperature Sensor for Solar Charge Controllers (RTS) | Epoxy-encapsulated, fits SunSaver MPPT, TriStar MPPT, ProStar, accurate battery temp compensation, surge protected - Image 1](https://m.media-amazon.com/images/I/71B6BbYDPTL.jpg) ![Morningstar Remote Temperature Sensor for Solar Charge Controllers (RTS) | Epoxy-encapsulated, fits SunSaver MPPT, TriStar MPPT, ProStar, accurate battery temp compensation, surge protected - Image 2](https://m.media-amazon.com/images/I/81Ypigexr6L.jpg) ![Morningstar Remote Temperature Sensor for Solar Charge Controllers (RTS) | Epoxy-encapsulated, fits SunSaver MPPT, TriStar MPPT, ProStar, accurate battery temp compensation, surge protected - Image 3](https://m.media-amazon.com/images/I/71WpJeB413L.jpg) ![Morningstar Remote Temperature Sensor for Solar Charge Controllers (RTS) | Epoxy-encapsulated, fits SunSaver MPPT, TriStar MPPT, ProStar, accurate battery temp compensation, surge protected - Image 4](https://m.media-amazon.com/images/I/51qe2ZMr7EL.jpg) ![Morningstar Remote Temperature Sensor for Solar Charge Controllers (RTS) | Epoxy-encapsulated, fits SunSaver MPPT, TriStar MPPT, ProStar, accurate battery temp compensation, surge protected - Image 5](https://m.media-amazon.com/images/I/51Jn7W-oueL.jpg) ## Frequently Bought Together - Morningstar Remote Temperature Sensor (RTS) - Connects Battery to Charge Controller to Provide Accurate Battery Temperature Info When Battery & Controller Temperatures are Likely to Differ by >5C - Morningstar SunSaver 15A MPPT Solar Charge Controller SS-MPPT-15L - Solar Panel Regulator, Supports 12/24V LA/Li Batteries.
