[RE-wrenches] Sol-Ark 15k Conduit Entries

[Michael Morningstar]

I just checked out the Homegrid batteries. Just throwing this out there. If
there is enough ceiling height you could hang them. That's typically how we
deal with transformers in commercial and industrial settings. We usually
build a permanent gantry out of square tubing, 1/2" rod and strut. Then
ratchet strap or chain hoist them up. Just an idea.

Yes Dave, that's the one.
