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.

For that matter, AC combiners, DC discos, any switchgear related to the inverter(s). Any help appreciated. Bill Feather River Solar Electric solar powered since 1982
