Web-based PV Monitoring System [RE-wrenches]

[Jason Lerner]

<x-flowed>
Hello,
We have been working with Ethan Brand to make a monitoring system  
that data logs,  and is available on the Internet.  It uses his basic  
"One Meter" and then adds the Internet aspect.  It uses shunts or  
donut transducers for AC or DC measurements and is very flexible with  
adding loads to be measured. We are measuring 4 AC channels, 4 DC  
channels, wind speed/direction and % full on a  Hydrogen tank.  It  
can be used with any equipment.  Each shunt has a Cat 5 cable that  
plugs into it,  with the other end going to a "base station".  The  
"base Station"  then plugs into the digital faceplate that also plugs  
into the internet.  Our site is remote and off grid the Shunts are  
all in,  it just passed inspection and we should have it online with   
Direcway in two months or so.  Ethan has about 6 of these meters out  
there,  and since we have been the guinea pig with four revisions  
already, He is excited to get this product out there.
