This manual introduces the use of the Remote Temperature Sensor (RTS).
This manual covers the Remote Temperature Sensor (RTS) used with Morningstar's ProStar or TriStar solar controllers. It explains when to use the sensor, noting that the ProStar requires it for accurate battery temperature compensation if the battery temperature differs significantly from the controller, while the TriStar uses it for temperature-compensated charging. The document also specifies the operating temperature range of -30°C to +80°C.
| Operating Temperature Range | -30°C to +80°C |
|---|---|
| Accuracy | +/- 1.5°C |
| Cable Length | 10 meters |
| Maximum Extended Cable Length | 30 meters |
| Power Lug Housing Screw Hole | 9.5 mm |
It is recommended whenever the temperature at the battery will be more than 5°C (9°F) different than the temperature at the controller.
No, use of the RTS is recommended only for battery charging or diversion control modes, not for load control mode.
Change the temperature of the remote sensor; if heated, battery voltage decreases, and if cooled, battery voltage increases.
