Morningstar RTS, ProStar and TriStar Remote Temperature Sensor

Morningstar’s Remote Temperature Sensor provides improved battery charging in solar systems that experience temperature variations during the year. The RTS measures the temperature at the battery. Then the controller uses this data for very accurate temperature compensation. When the temperature at the battery is more than 5°C (9°F) different than the temperature at the controller, the temperature sensor should be used. The TriStar has no onboard temperature compensation and requires the RTS to establish the temperature compensation. It is important to note if the RTS is not used, Morningstar controllers default to an onboard temperature sensor.

The RTS is compatible with the following Morningstar controllers: ProStar, TriStar, SunKeeper, SunSaver Duo, and the SunSaver MPPT.
