Can PW2s be 70 feet from the main panel?

Just might require larger gauge wires. or maybe not. Electrician will know, but I have had a PW up to 120 feet away.
They should be able to run the wiring for the two Powerwalls in one conduit. Depending on how you want it, the could run it inside or outside... or even in the walls.

Each Powerwall needs its own 30A 240V circuit. Parallel circuits are required, but can be in the same conduit.

You could have a sub panel that both powerwalls feed into that is then combined into one larger feed then run that to the main. I am not an electrician, but I don't see why you can't do that. It's probably cheaper to just make two runs to the main, though. Most electricians like to charge a lot for a new sub panel.

Why not just put them by the main? Then you can easily do whole house backup and get rid of some line loss. They're made to mount outside.

They don't make much noise. Some fan whirring. I'm not sure about electrical noise. But if you're willing to pay a little more for the pleasure of moving them, I don't see why not.

My PowerWall fan starts to get relatively noisy when my garage heats up over 100 degrees F. I can hear it from inside the house. The rest of the time it's pretty quiet. My contractor did not charge me extra for the wiring run through the attic from my electrical panel to the garage on the other side of the house. It only took them a few minutes

I installed a 150ft line 240 V 30 A. It's just a matter to use the correct AWG wire gauge.

Welcome to Arizona! Not an air conditioned garage, eh?
Not air conditioned - and the door faces southwest to boot. I've insulated the garage door and some of the outside walls, so the garage at least stays cooler than the outside air in the afternoon - but not by much. I have an automated fan that draws the hot air out of the garage at night - or anytime the outside temperature is cooler than the garage temperature.

I'm working with Tesla on a 2 powerwall system. I have a 200 amp main panel at the back of my house, and a 60amp sub panel in a separated garage with a guest house over it. Outside wall near the main panel is not ideal, its outside a bedroom window, and outside in the weather (snow in Northern California Sierra Nevadas)
I'm wondering if the powerwalls can be installed in the garage and ran off the existing 60 amp circuit? I have enough room in the conduit to change out the sub panel to a 90 or 100amp sub panel, but Didnt know if they will have to bring another circuit dedicated for the powerwalls or how that would work?
I like the idea of the powerwalls being somewhat protected in the garage, even though it's not heated.
