[RE-wrenches] Off-grid ground mount

[William Miller]

Allan:

We recommend the custom, top-of-pole 
roof-mount:

Just kidding!  (A customer rigged this up.  Scary...).

We have used the DPW TTRGM racks on flat roofs.  We have a few of them 
tilted up on pitched roofs, but I avoid lifting them because of aesthetics 
and wind loading.  If this is an off-grid, adjustability or at least a 
higher tilt angle is necessary, so this rack would suffice.  It does 
require at least two people, preferably three, to adjust.

We build them with the legs set to high and then lower them all of the way, 
or part way, depending on the design.  Some new modules do not have flanges 
in the back for through-bolting, these would not work.

We have also used various brands of extruded rail with legs to tilt them 
up.  See attached photo.  These get flimsy so I stay away from them.

Good luck.
