The bracket and cover is something I made because it’s winter and I’m bored.Sheet metal would be just as good.It could be 3D printed as well. The center of the bracket is directly over the frame so there are no cantilevered loads.This is why a printed bracket would be plenty strong.More about the cover/bracket you used please. The green button looking thing?
Have you a battery disconnect, or charger?
$15,000 is a retail price nobody actually pays,however $11,400(I paid)is a lot of money.Has me curious of the date of install vs doing a few powerwall 2 @ 12kWh/ea & $12,000 in the last few years.
Maybe you can have someone on this site print one for you.I've loved moving my battery to the firewall; when the trunk is as small as ours, removing the battery frees up so much room, especially for longer objects. Plus, pulling the power wires through the trunk grommet always took far more time than it had to, so removing the clam now is easy. This spring I need to remake my bracket, but mine is just bent sheet. That one is perty!
