Joel - Check out Locus Energy (http://locusenergy.com/). Key features:
- Production and demand monitoring - single and 3-phase options - relatively simple to install (for single-phase at least) - inverter direct monitoring for some manufacturers - user configurable performance alert emails - reasonable price point - good customer service Ask for Adrian and tell him Drew sent you... and he'll probably charge you double.

Each time, the end-user has been totally satisfied with what they ended up with. I haven't installed these in any commercial systems, but have them in several massive residential jobs (400-800A services). eGauge has an internal web server, so the hosting is free; no monthly service fee ever. Aside from showing generation (or usage if wanted), there is not much on the trouble-shooting side. For more info you need an inverter-direct system from Fat Spaniel or Energy REcommerce, and even then you don't get much beyond aggregate DC numbers and inverter error messages unless you spring for string monitoring and/or a weather station. Or if you happen to have SMA inverters, use their WebBox; we have several of those on commercial sites, work great, also free hosting. If you are looking for a single portal to host everything, you'll have to stick to third party unless you have all the same brand inverters. Adding monitoring to 50 sites in several states is no small project, and won't be cheap. And since you specify internet-based, be prepared for a lot of time troubleshooting networks. On commercial sires, this can be pretty tough (you might need a static IP address, etc). That being said, you should avoid a product that won't be there to support you through those installations and all the networking trouble you are bound to hit. -Phil On Thu, Nov 25, 2010 at 2:48 PM, Joel Davidson <joel.david...@sbcglobal.net> wrote: > > Hello Wre... _______________________________________________ List sponsored by Home Power magazine List Address: RE-wrenches@lists.re-wrenches.org Options & settings: http://lists.re-wrenches.org/options.cgi/re-wrenches-re-wrenches.org List-Archive: http://lists.re-wrenches.org/pipermail/re-wrenches-re-wrenches.org List rules & etiquette: www.re-wrenches.org/etiquette.htm Check out participant bios: www.members.re-wrenches.org
