I assume you are talking about the battery to inverter cables - it's amazing how many people think that AC electricity uses positive & negative! First of all check to see if the heating is localised around a terminal (both ends) or along the whole length. As you only mention the positive cable I suspect its may be a loose or badly fitted terminal, if it were cables then as both cables should be the same size I would have expected you to say "positive & negative cables get hot". If it is localised towards a terminal ensure the actual terminal is man enough for the current it has to carry and then make sure it is crimped tightly to the cable with no sings of burning. Make sure the terminal nuts/screws are tight. If the whole cable heats up then please change BOTH cables for heavier ones. I can not help you with size because I do not know the lengths or current being carried. Both sets of notes on my website give you the calculation and aim for less than 0.5V of volt drop.
