The eGauge can measure battery voltage now (using L3 input), been running with it for months, and they are finishing up work on a DC CT to show amperage too. Fantastic product, and now even more so for the off-grid crowd. This is the first time we can really see what it happening in remote sites - when the batteries run down, the generator runs, how loads affect both; we can get emails and/or text messages to keep track of generator run time (think failure to auto-stop), etc.

Now, what do you want to measure. Being an off-grid system, all you can measure is the output. The normal use for an egauge is to compare load with output in a grid tied system, or output to utility export/import in a hybrid system. In the system I just set up, it would only show the power output of the inverter, as the CTs cannot measure the DC output of the solar system.

I am trying to demonstrate for a potential customer what and E-Gauge display on an off-grid system would look like.
