I've been tempted to get another unit for our bedroom and power it with our solar but it's not always that hot in our master bedroom apart from a few nights a year (few nights inbound!), but it's been a god send in my office bedroom which is south facing as I can have it on all day cooling the room whilst I work.

Is it possible to add extra room units to an existing install later on or would that require an extra external unit?

e.g. if I got the 2x bedrooms done and then added the living room 6 months later - Do I need an extra outside unit (whatever they are called) or can I add it to the existing unit, assuming that it is specced to run 3x units in the first place of course.

As long as you buy an external unit that supports enough in door connections then you can add internal units later
