There is a new one mentioned in SolarPro, from a company called CURB http://energycurb.com/) . CURB gives CT’s for eighteen different circuits so over time you can understand how each load is performing. One of our families had a broken pump shaft so it never registered that there was more water in the pressure tank, so it ran for weeks. The site mentions that they will be able to predict appliance failure from historical data. And it can monitor overall PV generation. It looks very promising though from the reviews it may not yet allow a download of historical data. It would be great if in addition to logging data, it would allow active management of interlocking relays to control demand charges. There is another product called Energy Sentry (http://energysentry.com/ ) , that allows you to prioritize your large loads so they aren’t allowed to all come on at the same time. As more utilities add Time of Use and demand charges this will be a really valuable piece of hardware. For installers this will become just another value added service. These two companies should merge.

It seems most just deal with the array output as a load . Thanks.
