I got a Growatt 12kw - it weighs 165 pounds (and apparently I am not in as good a shape as when I was in my 20's). Normally if I have to mount stuff on a cinderblock wall, I first mount a sheet of 3/4" plywood (using 1/4"x20 read heads - expanding sleeve bolts) and then mount equipment to the wood.
BUT...that's not for heavy stuff. I would only be able to use 1" screws/lags to secure the inverter to the plywood and I'm afraid that's not enough (there are spaces for 6 mounting bolts). Is the plywood overkill and I'm better off just mounting to the block? I'm concerned about moisture forming on the surface of the block behind the inverter (figured with plywood there it would not be as bad).
If I do go with plywood, I also had concerns for fire - was pondering putting 1/4" cement board up on top of the plywood.
Opinions?
