Hugh....Typically the temp Sense warning is not related to an external temp sensor, rather an internal temperature sensor. The Outback inverters typically will run normally even with this temp sensor not working. I believe it is related to temperature of one of the boards and relates to turning the cooling fan on if present - normally it is not related to a battery temp sensor which is what I got the impression you understood it to be. However, typically this will show up as a red blinking error light which signifies a warning instead of a solid red error light during which the inverter may stop working.
