Figure 5-43, Tfmr Overtemp Fault
• Tfmr Overtemp (Tfmr OT) – This fault message displays when the transformer temperature
is >130°C, causing the Thermal Cut-Out (TCO) sensor on the transformer to open. If the TCO
sensor stays open after 10 seconds, the inverter auto-resets. This fault also happens if any line
in the TCO sensor is open.
Remedy: Remove all power (AC and DC) to the inverter and let it cool down. After the
inverter has cooled down, reconnect the DC side (batteries). If:
a) the “Tfmr Overtemp” fault returns or the display reads “No Inverter Found!”, then the
inverter requires service/repair.
b) the inverter is now working, ensure the inverter is in a cool location, has adequate
ventilation, and the internal cooling fans are operational.
Unknown Fault ## appears on the LCD and the FAULT
(red) LED is on. The PWR (green), CHG (green), and
INV (green) LEDs are off.
