Installation Steps 

The Battery Temperature Sensor (BTS) extends the life of the battery by preventing overcharging in warm temperatures and undercharging in cold temperatures. The BTS provides the Inverter/Charger with precise battery temperature information to automatically adjust the absorb and float charge voltage set points. If the BTS is NOT installed and the battery bank is subjected
to large temperature changes, the battery life will be reduced.

• Install the battery temperature sensor ring terminal onto the NEGATIVE battery terminal.
• Route the sensor’s cable to the Inverter/Charger following existing wire runs.
• Connect the RJ11 connector end of the BTS cable to the “Battery Temp” port on the Inverter/Charger.
