[RE-wrenches] SB -40 Wi-Fi

I'll throw in a vote for keeping the display on the SMA inverters with a 
similar level of info provided by the -22's and the -40's. It's right 
there, reliable, simple though adequate info for both monitoring and 
troubleshooting, it would be a great loss.  Not everybody wants to be 
"connected".

             I'll try Jerry's idea of the headlight restoration polish 
for the yellowing display.  Also keep them out of the sun and the 
clarity stays much longer.  I've been experimenting with a small piece 
of UVA/UVB glass secured to the front of the display window with outdoor 
rated 3M 2-sided tape, I'll report back in a decade!

            For the manual I guess the best option is to goto: 
http://files.sma.de/dl/27676/SB30-77-1SP-US-40-BA-en-11.pdf

and print the user manual for these inverters and add it to the binder 
in the truck.  Yes, its 68 pages but could save a trip out and many of 
the pages need not be printed (warnings, etc).
