<DIV>James could advise you as to multiple power inputs. I also think he as alarm settings.. On a demand reduction system I am just performing monitoring using a very cheap <BR>TED. I am working on a building with 800 amp single phase service, I just purchased a couple of CTs busbar clamp size and replaced the factory supplied ones. But I am taking a different route for my inverter generator control. </DIV>

<DIV id=yiv1108061111>eGauge is not revenue grade, but could cover your requirements (1), (2), and (2). The proprietor David Mosberger-Tang (<A href="http://us.mc519.mail.yahoo.com/mc/compose?to=davidm@egauge.net" rel=nofollow target=_blank ymailto="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>
