We recommend using the Morningstar Remote Temperature Sensor (RTS) whenever the temperature in the batteries is subject to variation of more than 5°C (9°F) during the year. The RTS will measure the temperature at the batteries and provide a more accurate charging for temperatures from –30ºC to +80ºC.
The RTS is compatible with the following Morningstar charge controllers:
- SunSaver MPPT
- SunSaver Duo
The temperature sensor is encapsulated in epoxy inside a power lug housing. It comes with a 33 feet (10 meters) cable and is protected from lightning surges and short circuits.
