When we installed solar panels, I decided to add a egauge E3000. I think I have spent far too much at this point on energy monitors. I started with a "One Meter" 10 years ago, then Ted, then Brultech, and now an eGauge. The eGauge is the first system I would call robust and stand alone. While the Brultech has more user accessible features, it is so brittle, has archaic software, and so dependant on other hardware to be useful. It has since stopped working and I can't find the motivation to keep it working (software). The eGauge on the other hand is a next generation solution in comparison, but unfortunately the DIY community has not really discovered it, so there is virtually zero support in the systems I use. Universal should take note of their architecture and aspire to make their systems as self contained and bullet proof.
