What to do if Xantrex Freedom SW Inverter shows FET1 Over Temperature?

  Scott TaylorJul 27, 2025
  If the Xantrex Inverter displays a FET1 Over Temperature error, several factors could be the cause. First, ensure adequate ventilation around the inverter and allow it to cool down before restarting. Remove excessive inverter loads if you are operating too large of a load for too long. Check if the inverter cooling fan is working—it should be on if the temperature is above 104 °F (40 °C). Also, ensure that the inverter airflow intake is not blocked by increasing clearance around the inverter and unclogging the airflow intake vents.

  If your Xantrex Inverter is showing a DC Under Voltage fault, check the battery condition for shorted or open cells and ensure the correct voltage. Verify the correct battery voltage at the inverter's DC input terminals. Also, check for external DC loads on the batteries. Recharge the batteries if necessary. You might also consider reducing the Low Battery Cut Out (LBCO) setting. Keep in mind that the battery bank capacity may be inadequate for the loads in the system.

  If you see a Battery Over Temperature warning on your Xantrex Inverter, the battery temperature may be over 140 °F (60 °C) due to poor ventilation. Stop charging if necessary and check cable connections, battery voltage/current, and temperature. If the battery isn't accepting a charge, it might need replacement. Check for excessive ambient temperature and ensure adequate ventilation in the battery compartment. Also, if the unit displays a temperature over 212 °F (100 °C), the Battery Temperature Sensor (BTS) may need replacement.

What causes DC Over Voltage on a Xantrex Freedom SW Inverter?
- J
  Julie RoseAug 12, 2025
  If your Xantrex Inverter is showing a DC Over Voltage error, it means the voltage at the DC input terminals is above the High Battery Cut Out Setting. Verify the correct battery voltage at the inverter's DC input terminals and check all other charging source outputs and battery cables.
