Trace SW noise levels. [RE-wrenches]

[allan]

We have started doing some system installs with the power equipment in a
rain- and dust-protected, vented enclosure, maybe 4' by 6', mounted on or
next to an exterior wall of a house, with the batteries in a sealed, vented
box located on the inside of the same exterior wall (for winter warmth).  So
far it has worked out pretty well, and it's code-legal.  We still warn
clients about inverter noise.
