[RE-wrenches] My .02 - 12/24v garage door opener.....

[Dave Angelini Offgrid Solar]

Not even going to mention building code and running DC wiring outside of
the area (battery/inverter/chargers location) an inspector would allow.
Even some of the very rural/extreme remote counties I work in know that
they are ill-equipped to inspect DC wiring. Some will tell you there is no
inspection for offgrid homes but if there is a fire they will say they
told the installer no DC wiring except in the area of the battery.
