Here is another widget that might be worth looking at. It seems to be priced around the TED option, but may have more bling.

The proprietor David Mosberger-Tang (dav...@egauge.net) 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. 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.

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