I believe that I was told in a 2005-ish Xantrex GT training that their
minimum clearance (~30") requirement came from the need to be above lawn
sprinklers. I can't remember offhand seeing this reason given in any
recent manual, so any bottom clearances required in the manual may apply
to you even if you're inside.

Bob-O, Peter, Garrison,
I appreciate the responses, will proceed accordingly. I have
seen some references to minimum distance to floor in some manuals.
Thank you,

Bill,
See 2011 NEC 690.14(D) or 2014 NEC 690.15(A) Utility-Interactive
Inverters Mounted in Not Readily Accessible Locations. Basically
there is no maximum height restriction for inverters but there are
a number of requirements for AC and DC disconnecting means. See
NEC 404.8 for maximum disconnect height of 6’ 7”…although
exception No. 2 may allow the disconnect to be accessible by
portable means. I don’t know of any minimum height requirements
in the code, although most (all?) string and microinverter
manufacturers specify a required clearance below the inverter. I
suppose that would be the minimum.

Wrenches,
I can't seem to find a reference to the heights allowable
for inverter installs, either minimum or maximum (need both). For
that matter, AC combiners, DC discos, any switchgear related to
the inverter(s).
Any help appreciated.
