A battery that is hot needs a lower charging voltage; a battery that is cold needs a higher one. Without a temperature reading, a charge controller has to assume a fixed battery temperature — which means your batteries are being overcharged in summer and undercharged in winter.\u003c\/p\u003e\n\u003cp\u003eThe Systellar Battery Temperature Sensor is an optional accessory that measures the actual temperature of your battery bank and feeds it back to the charge controller, so charging voltages are adjusted continuously to suit real conditions. The result is a properly charged bank and longer battery life.\u003c\/p\u003e\n\u003ch3\u003eWhy fit a temperature sensor\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eCharging voltage automatically compensated for actual battery temperature\u003c\/li\u003e\n\u003cli\u003ePrevents overcharging and excessive water loss in hot weather\u003c\/li\u003e\n\u003cli\u003ePrevents chronic undercharging and sulphation in cold weather\u003c\/li\u003e\n\u003cli\u003eExtends usable battery bank life and protects your investment\u003c\/li\u003e\n\u003cli\u003ePlug-and-play — no configuration or calibration needed\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eHow to install the sensor\u003c\/h3\u003e\n\u003col\u003e\n\u003cli\u003e\n\u003cstrong\u003eClean the surface.\u003c\/strong\u003e Wipe the side or top wall of your battery bank to remove any dust or grease.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAttach the probe.\u003c\/strong\u003e Use double-sided adhesive tape to firmly paste the sensor probe onto the side of the battery.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnect to the controller.\u003c\/strong\u003e Plug the 4-pin RJ11 connector at the end of the sensor cable into the designated battery temperature sensor socket on the left side of your Systellar charge controller.\u003c\/li\u003e\n\u003c\/ol\u003e\n\u003ch3\u003eDefault behaviour\u003c\/h3\u003e\n\u003cp\u003eIf the sensor is left unplugged, the charge controller automatically falls back to its standard charging parameters, calibrated for \u003cstrong\u003e25 °C\u003c\/strong\u003e.
