Remote Temperature Sensor
The Remote Temperature Sensor™ (RTS) improves battery charging accuracy by measuring battery temperature directly and automatically adjusting charging to match changing environmental conditions. By providing precise temperature compensation, the RTS helps maximize battery performance, extend battery life, and support reliable operation across a wide range of off-grid applications.
- Improves charging accuracy with battery temperature compensation for optimal charging performance.
- Extends battery life by adjusting charging based on actual battery temperature rather than controller temperature.
- Recommended for installations where battery and controller temperatures differ by more than 5°C (9°F).
- Required for temperature-compensated charging with TriStar™ charge controllers and enhances charging accuracy on other compatible Morningstar products.
- Compatible with TriStar™, TriStar MPPT™, TriStar MPPT 600V™, ProStar, Prostar MPPT™, Sunsaver MPPT™, EcoBoost MPPT™, SunKeeper™, SunSaver Duo™ and EcoPulse™
