The IC Series Inverter/Charger is delivered with a battery temperature sensor. By installing this sensor, the charge voltages are automatically adapted for deviating temperature. With a BTS installed, if the temperature around the BTS is below 20°C, the absorb and float charge voltage increases. If the temperature around the BTS is above 20°C, the absorb and float charge voltage decreases. The
graph below details how much the charge voltage changes (increases or decreases) depending on the temperature reading of the BTS.
