Remote Temperature Sensor

SKU: RTSMS Category:


Remote Temperature Sensor for Morningstar Controllers (RTS) provides improved battery charging in solar systems that experience temperature variations during the year. The Remote Temperature Sensor measures temperature at the battery and the controller uses this data for very accurate temperature compensation.


Use of the RTS is recommended whenever the temperature at the battery will be more than 5°C (9°F) different than the temperature at the controller. The TriStar has no on-board temperature compensation; therefore the use of the RTS is required for temperature compensated charging. Other Morningstar controllers will default to an on-board temperature sensor if a RTS is not connected.
The RTS is compatible with the following Morningstar controllers:
• ProStar™ (soldering required)
• TriStar™
• SunKeeper™
• SunSaver Duo™
• SunSaver MPPT™
