OP guy (hasn't posted here for 4 years) puts his inverter on the front edge of the engine compartment; on my 2018 at least, that's not really a very stable spot. I'm wondering, why not sit it on the cover at the top of the "engine" stack ? (On my car that is plastic, on earlier models it appears to be aluminum). Doesn't seem like a cooling-critical location, and putting some nice rubber feet on the inverter would prevent any telltale marks from being left. I want to figure this out in advance, to size those big 2awg cables (from big connector to inverter) just right.
