I live in North America and have 240v 2 phase grid tie, and 240v 2 phase solar system

It looks like I need two three phase monitors, and not use third leg. Has anyone done this installation.

Eventually I would like to monitor my 240v 2 phase geothermal system, and also monitor my 240v 2 phase EVSE charging system for my automobile

Let me confirm some issues,

1 The grid is 2 phases, it has 2 living wires and one neutral line, and the voltage between living and neutral is around 240V, yes? If so, what is the frequency? 50hz or 60hz?

2 "and 240v 2 phase solar system"

please help us to confirm, whether it is 2 phase(have a neutral line) or phase-phase(no neutral line) output?

if it is a phase-phase inverter, you just need one 3 phase energy meter (WEM3080T) + one single-phase energy meter(WEM3080). Like this post https://imeter.club/topic/100

In United States a typical home has 240v electrical service.

That consists of two live wires, and one neutral (ground)>

Voltage between live wires is 240V. Voltage between each live and neutral is 120v

Frequency is 60Hz

Main feed from grid 240v,,,, feed from solar inverters 240v

Hi:

Thanks for your confirmation.

Now I confirm that  is the same question as this https://imeter.club/topic/100

The three phase energy meter WEM3080T also support split phase usage, you can take it as three single-phase energy meter which have same neutral line.
You can install one WEM3080T(3 phase energy meter) to monitor the 2 phase grid .

For the phase-phase inverter ,you can use one WEM3080(single-phase energy meter) to monitor it.
Install the WEM3080 in this way,

"you connect the Ua and Un to the inverter output,
clamp the ct to one of the outputs of the inverter."

This is different than:

Is there a way to share drawings or diagrams?

The diagram is like this 

Since CT3, or "C" is not used, is there a way to not show it on the graph in the place view. (using Cloud)

Hi,
If you only install the meter in grid side, the monitoring page style will be the same as below.
The power of phase C will display zero in the overview page, you can also closer the power display of phase C

If you install meters in both grid and inverter, the display style will be like this(in solar pv monitoring mode).

There will be no display of power C in the monitoring view.
