eGauge Dashboard

The eGauge monitor can track up to 12 single-line channels. These channels can each be used to measure individual 120 volt loads, doubled up for 120/240 volt split phase loads or tripled to measure 3-phase power.  Voltage ratings and current transformer (CT) ranges make the unit suitable for small commercial applications as well as residential.

The dashboard does a nice job of tracking alternative energy generation along side grid power consumption.  It not only tracks energy history but provides instantaneous feedback of the amount of alternative power being produced to the amount grid power being purchased.

The time line for tracking energy is adjustable from minutes to years.  Credits from alternative energy generation are netted against grid power in a simple table to keep track of any power sold back to the grid.

Main Dashboard Showing Load vs. Solar Power Generation

Looking at the main dashboard in greater detail, we find that the red line shows total load with the pink shading underneath representing energy purchased from the utility.   The green line shows the power produced by the photo voltaic cells and the green shading shows surplus solar energy that is sold back to the grid or credited to the electric bill.

The dashed green line is a sub-metered portion of the solar array measured on a separate channel.   The white area indicates solar generated kilowatt-hours that replaced grid energy.  The bar chart on the right shows the dynamic, ever-changing level of power generated vs. power used.

This makes for an interesting dynamic but what is the bottom line at the end of the month or the end of the year?  The following table tracks this type of historical output:

Depending upon the type of distributed generation agreement you have with your utility, this table may prove helpful in reconciling any kilowatt-hour credit differences.

Since the system has a wide range of CT's and the ability to capture single, split phase or 3-phase power a many different configurations will exist. To accommodate this variety, the system set-up screen uses pull-down menus to simplify the configuration process.

CT sizes are assigned to the specific devices they measure.  Registers are used to assign and/or group CT's and line voltages to determine the power calculations for each device.  Totalling takes input from grid power, generated power and sub-metered devices to calculate net power which is unique to each installation.
