Thanks for your post and email and I'm sorry about the slow reply, I've been away on holiday over the last two weeks, Nice work with your build! Thanks for the photo. I uploaded it to my picassa so that I can link though to it here, did you have a image option in your post box?

Thanks

Thanks for the wealth of information on your site. I managed to cobble together a modified version of your Power Meter. I decided to use a design that allowed a Current Transformer (Seeed Studio Depot SCT-013-000/THM105C4B) or alternatively a Hall Effect device (Pololu ACS715), to be used via a PCB jumper.

Mr. Murphy didn't help but the Veroboard PCB version produced good agreement between the two device types and a cheap commercially available Power Meter.

Next step is to marry in an Adafruit Logger Shield, so as to log data to a SD card.

If you could provide an email address, I could email a photo of the current setup. Hope this is of help to anyone contemplating a similar application. If anyone is interested in further details, please feel free to email me at matthodge@iinet.net.au

cheers,

For what it's worth, here's what I've found so far, for monitoring renewable energy systems.

Fat Spaniel
Used for MGE turbine at McKee Park in Fitchburg:
McKee Farms Park

Deck Monitoring
Used for Kettle Chips installation of Aerovironment turbines in Beloit:
Kettle Chips in Beloit, WI

Onset Computing
Their web-enabled data loggers offer an on-line software:
HOBOLink
For example, a solar thermal system in California:
Solar Thermal System in California
Kevin Little, Informing Ecological Design, created an on-line monitoring solution used for wind power and buildings, WebViewer (no longer available), and now uses Onset and others, and has expressed a willingness to advise. He provided a two-page description of his experience with this combination of Onset logger and software.

Logic Energy
“Logic Energy Ltd. specialises in providing monitoring and reporting services via the Internet, principally for the renewable energy industry. Our systems allow remote monitoring of energy systems, reporting and control of failures all via a web browser.”

In addition, I guess a number of inverter manufacturers offer packages. For example, SMA makes the Webbox.

Thanks for the post, interesting stuff, I had a bit of a search around the APRS site and found this:

Technical Information - Open source hardware and software!
We believe in open source hardware and software. You can find the Wind Data Logger schematic and other technical material in our manuals and documentation section. Please feel free to contact us if you need further information.

[www.aprsworld.com]

These guys look like they are right on! nice find!

found the open source software for the wind monitoring here (source code is at the bottom of the page): [www.aprsworld.com]

If its no difficulty to send the list, yea I would be interested to see it and Im sure others would find it useful too.

Thanks

APRS World, Inc.
Their web site doesn't say that they are open-source, but I have confirmed that they are, over the phone. They are "...working on a new system called ReDAS (Renewable Energy Data Acquisition System). The new system does need a live internet connection on site, but it will be much more flexible and expandable than our current offerings. It allows you to simultaneously monitor multiple outputs from different inverters, along side a variety of other wind and weather sensors. We're still working on the new web interface and display for this new system..."

Etesian Technologies
The company owner was working on an open-source wind data logger. They also sell a nifty wireless, battery-less, anemometer-logger-display pair. The anemometer generates enough current to send the data packets down to the logger and display.

I'm not interested in creating the hardware and software, only in explaining the options to my client. In turn, I doubt they will want to go the open-source route, although I'll certainly present it as an option. At the same time, I can't imagine a technical college being happy with Fat Spaniel as a display solution. So I'm still looking... if you're interested, I can send my annotated compilation of web sites that I've found so far.
