During one of our webinars, a question came up about battery temperature sensing associated with Morningstar charge controllers. Just to clarify, our TriStar MPPT family of controllers come with a remote temperature sensor (RTS) included. The TriStar PWM does not come with a remote temperature sensor but an RTS can be purchased separately.
All other MS controllers include an internal temperature sensor. In addition to the TriStar PWM mentioned above, if more accurate battery temperature sensing is desired, the RTS accessory can be purchased for the SunSaver MPPT, SunKeeper, SunSaver DUO, and ProStar.
