inverter data transfer[RE-wrenches]

[Ryan Mayfield]

Jeff,

I've done a fair amount of research on the subject recently and would
suggest you visit the CEC site:
http://www.consumerenergycenter.org/erprebate/monitors+rsp.html for the
list of CA approved monitoring solutions. I'm sure all the companies
listed there could help you out. In addition to those there are a few
others that would be worth looking at:

Chuck Wright Consulting - http://www.chuck-wright.com/
Heliotronics - http://www.heliotronics.com/
R meter - http://rmeter.com/
Soltrex - http://www.soltrex.com/

Feel free to contact me directly with any further questions.

We are designing a mid-sized grid-tied system for a University building
under construction which will have several separate inverters.  They are
adding a large flat screen monitor system (by others) that will display
school event schedules and other information in the lobby and want to
include a "window" that shows real time data for the pv system.  We have
tied several Fronius inverters together in the past which have an
optional data card and connected to a desktop computer which worked
well, but you still needed an operator to download and graph the data.
I wanted to see if anyone out there has anything newer and easier, that
does not require any computer operator to update or graph the data.  

To reduce wire runs, I was thinking of some type of "black box" small
computer without a screen or keyboard that we could mount next to the
inverters located in the mechanical penthouse and let the computer be a
node on their local area network which also allow access by others in
the science classrooms.   I have seen these before but thought maybe
somebody has finally put a complete data package together and I won't
need to get out the soldering iron and data converters.

Thanks,

Jeff Yago
