Can anyone with a Powerwall2 tell me if the bottom of them are completely flat, or whether they have some protrusion or "feet" on the bottom that they rest on when installed on the floor? I'd like to know if my DIY stand should be flat or accommodate any such "feet" if the Powerwalls have any. This is my tentative design for a wooden stand I want to build for my 3 "stacked from the wall" Powerwalls to sit on top of. This will be inside of my garage. My installer said it'll pass my city's code as long as it's built really sturdy. I need the PWs sitting 12" high off the garage floor so that I can retain 1 of only 2 garage vents left in my garage. Everything will be screwed together solid with 3" drywall screws, 3/4" plywood on top, then painted white to match the Powerwalls. I might add a couple of timer-controlled 12vdc box fans for venting the hot garage air further during the hot months of the year, just for some extra ventilation. Do you see any issue or concerns about this design? Is there anything else that I should plan for in an installation where 3 are stacked 1 in front of the other? I need the stand to be able to support a minimum total of 750 lbs (250 x 3 PWs). Any suggestions from those who have PWs mounted on the floor would be greatly appreciated! Thanks!
