Hi! 

I have set up my solution where I have 2 inverters with IAMMETER 3 phase and on measuring import export to grid. Everything works great in the IAMMETER platform but when using home assistant I do not get any solar readings. (just minor). See below. I know this is kWh vs W. But it's a sunny day so if should show much higher on solar. 

From IAMMETER it look like this:

In HA it looks like this

So electricity usage seem correct.

Solar production on the other hand is wrong. I shows some minor production at night time :( and nothing at day time. Compare to IAMMETER graph  

 In HA I have configured all 3 phase of the inverters like this:

Does anyone know why I cant get the readings right?

You can compare the raw data at each time point between IAMMETER Cloud and Home Assistant to see if there is any difference.

I have also config the 2 solar inverters.

i chance the way of the cable.(mesure)
