What model number? I have the
Xantrex RS2000 (obsolete) manuals I downloaded from the Xantrex website, it's temperature operating range is -4 deg.F to 122deg.F. They have a customer service number I once called, the man was quite helpful with my obsolete inverter/charger. My problem was high battery float charge, he said to unplug the battery temperature sensor and the inverter would revert to factory specs. They have no spare parts for my model, but his work-around works. After a few months I re-attached the temperature sensor phone cord, and it began working properly again. I still have a problem of the charger staying in float charge when it should kick up to bulk while boondocking, a reset solves that for a few months.
