The RTS (Remote Temperature Sensor) ensures an OutBack system knows the precise battery temperature so that batteries can be recharged safely and efficiently.

The OutBack Remote Temperature Sensor (RTS) is a necessary tool for proper battery charging. All OutBack products with integrated battery charging have a temperature compensation system built-in which benefits from the installation of the RTS (included with inverter/chargers).  Systems with multiple OutBack products connected to one HUB4 or HUB10.3 require installation of only a single RTS.
