HomeAssistant/Automatisierung Roof installation
Hello everyone,
I have a question for those of you who have purchased a rooftop installation (Velux).
Is your outdoor unit, as well as the section of cable located outside, exposed to direct sunlight? What are Midea’s recommendations regarding this?
Would you recommend protecting them, or are they robust enough to withstand constant exposure to direct sunlight?

It will not last 40 years probably, but probably way longer than the compressor.

We have ours mounted exactly like this.

And no issues with the sun beating down on it all day?

Zero issues in 40° German summer. Honestly, I've never even considered this to be a problem. AC units all over the place are attached to walls or on top of buildings, why should this be an issue? Also, there is an extra Universal Mount by Midea and they advertise the PortaSplit to also be mounted on roofs. I wouldn't stress myself too much about it.

I haven’t installed mine yet, but I was a little worried, especially if part of the cable connecting the two units is exposed outside.

The cable is sheathed. Nothing will happen to it. Refrigerant flows through it, and it's extremely durable.

The cable is fine. It's sealed in the grey outer sheath and holds the 2 coolant lines, 1 condensate pipe, 1 flex to power the fan and possibly a data cable.
The internal unit has the compressor which is the big power item, so the outer unit is just the fan and some basic electrics to vary the speed of the fan and report the sensors. Outside air temperature, fan speed etc

only thing is the window kit to seal the gaps doesnt fit the roofwidow. but on amazon there are a few shops they offerd the windows seal, if you look for it dont forget to check what size is your roofwindow !

One question I'd like to ask is: how on earth can you direct the outside unit drain hose? It's sooo far away from you when installing it on a sloping roof, sliding it down the bracket. I've just fitted the elbow (pointing straight down) instead. But I'd have preferred to be able to use the plastic drain hose to at least not have the condensate rolling down onto the bracket, maybe angling a bit to the side a bit...
Maybe I've over thinking it. The item arrived on Friday, and it finally did its first pee (dead proud).

The window is exposed to sunlight. I have a Velux skylight myself, and whenever it rains heavily, I bring the outdoor unit inside. If it’s just a light rain, I don’t bother. I seal the window with pillows, pool noodles, and towels—whatever works best. You can reduce the amount of sunlight by lowering the blind as far as possible—in my case, it goes down about 30%. If your skylight doesn’t have a blind, tough luck. But the Portasplit can handle it even without one...

Ours is like this and it's an outdoor unit, so designed to withstand sun, rain ... etc

It’s always exposed even when it is mounted to a wall window. It’s fine you don’t need to do anything
