Manufacturer Part Number: RTS

Remote temperature probe for use with the ProStar, TriStar, and all other Morningstar controllers that can use a battery temperature probe. For use with the ProStar the leads must be soldered to the circuit board, the TriStar is provided with a terminal strip for connection.

The RTS is compatible with:

• SunSaver MPPT
• SunKeeper
• SunSaver Duo
• ProStar : The temperature probe is recommended whenever the temperature at the battery will be more than 5°C (9°F) different than the temperature at the controller.
• TriStar for battery charging or diversion control modes (not for load control mode)

For maximum protection from harsh environments, the sensor is encapsulated in epoxy inside a power lug housing. The RTS is also protected from lightning surges and short circuits.

Do I need a Temperature Sensor? Maybe, but maybe not. If your batteries are at a different temperature than your controller (more than 10 degrees F - Morningstar recommends 5 degrees), then yes you probably should. For instance, if your controller is inside but your batteries are outside in the weather, the built-in temperature compensation would not be correct.
