eGauge is not revenue grade, but could cover your requirements (1), (2), and (2). The proprietor David Mosberger-Tang (<a href="mailto:davidm@egauge.net">davidm@egauge.net</a>) is pretty savvy with programming too, and he might be amenable to adding a programmable alarm, since it is just software. Depending on how many loads you need to monitor (how many CTs you need), parts would be in the $1,000 range.<br>
<br>Fat Spaniel could do all of it, but it can be difficult to get the attention you need if the project has custom programming aspects. And you are stuck paying a monthly fee for the life of the system.<br><br><meta http-equiv="Content-Type" content="text/html; charset=utf-8"><meta name="ProgId" content="Word.Document"><meta name="Generator" content="Microsoft Word 12"><meta name="Originator" content="Microsoft Word 12"><link rel="File-List" href="file:///C:%5CDOCUME%7E1%5Cphil%5CLOCALS%7E1%5CTemp%5Cmsohtmlclip1%5C01%5Cclip_filelist.xml"><link rel="themeData" href="file:///C:%5CDOCUME%7E1%5Cphil%5CLOCALS%7E1%5CTemp%5Cmsohtmlclip1%5C01%5Cclip_themedata.thmx"><link rel="colorSchemeMapping" href="file:///C:%5CDOCUME%7E1%5Cphil%5CLOCALS%7E1%5CTemp%5Cmsohtmlclip1%5C01%5Cclip_colorschememapping.xml"><style>

I am joining this thread a little late, so I may have missed a bifurcation<br>
into a related area.<br>
<br>
We have need for a DAS system that does the following:<br>
<br>
(1) Monitors inverter output, including some bigger commercial sized<br>
inverters from Satcon and SMA (100 kW to 500 kW)<br>
(2) Monitors utility input at service panel<br>
(2) Monitors several loads (up to five) via the service panel<br>
(3) Irradiance and temperature would be great but not absolutely necessary<br>
(4) Some sort of alarm system that would trigger at a programmable kW<br>
threshold for the utility input.<br>
<br>
What we are trying to do is monitor not only the PV system but the utility<br>
demand and key loads as well, and to come up with a strategy for shedding<br>
load to keep the demand below a certain amount.<br>
<br>
I know this is a fairly tough spec, and we may have to do some customization<br>
and/or programming to get what we want.<br>

I think the big this here is Low cost? Maybe we should define the price<br>
range so we can get a better fell of the product range?<br>
