Michael,
Any pictures of that bracing system pre battery mount would be greatly
appreciated.

We hang a lot of AES on wooden stud walls. Our engineer prescribed the
following: 1-5/8" strut bolted to every stud in the span. AES factory
mounting brackets bolted with 3/8" grade 8 bolts and thick strut cone nuts.
Then a support brace 3-1/4" strut which is (2) welded back to back 1-5/8"

Aloha all,
For those of us solar peeps who have installed positive grounded SunPower
mods years ago that require grounding in order to perform properly, I/we
have been impatiently waiting for SunPower or *someone* to offer a device

I agree with James here. I will relate a "funny" story about a neighbor
mounting a large Elk antler rack on his wall with lags. Worked fine,
till one night they heard a big crash, and the antlers had pulled the
wall stud right out of the wall into the living room. The 2x 4 came
right out of
Having witnessed the aftermath of others who have installed batteries by
bolting brackets to wood stud walls, my advice is do not do it! You reinforce
the structure prior to mounting the batteries but failing to do could result in
a catastrophic failure. When in doubt consult with your friendly
Buckling of the wall studs is most likely going to be the failure mode. You
can use WebStructural to look at different designs. You'll find that
accurately defining the constraints on the structural members is the most
troublesome.

Personally, I don't think that
2x4 studs have compressive force to hold up over 1,000 pounds each when
constructing a load bearing wall, so I don't think that is a limiting
factor. But I am not a structural engineer, so consulting one would not be
a bad idea.

Thanks Jason,
I’m still wondering if there is an IBC reference for weight. The Discover
manual only states:
“ For structural and seismic stability, the AES Battery must be mounted
onto a vertical supporting surface strong enough to support a minimum of
227 kg (500 lbs) per battery. Failure to
That won't be a problem as long as they are spread across several studs.
Even 2x4 studs would be fine. Check the installation manual for details.
The shear and pull out strength of the fasteners will be the limiting
factor, not the wall itself unless very poorly constructed.
Hi all,
I have a project where I am contemplating hanging 9 Discover AES batteries
on a wall. Each battery is around 200 lbs, and although the stud wall is a
bulky 2”x6” with 16” OC…I have apprehensions that hanging almost a ton of
battery on the wall is a good idea. I’ve seen it done in other
10 matches
