Solar inverter power consumption

[eunbyoll]

Hello,

One thing I have noticed is that the solar inverter always showing negative number even though no sunlight at all.

For an example,

At day time,  the inverter is producing power  -> Negative number

At night time, the inverter is consuming power(idle power approx. few watts) -> should be positive number

Overall it is great product!

you guys are awesome!

This is a known issue.  Although the clamps are able to measure current flow either direction, currently Emporia is taking the absolute value of the current readings.  Loads are always shown as positive, and solar always negative.  The feature has been requested – vampire draw of the solar inverters is not taken into account as you note.

Good to know that.

Thanks!

I need the Solar clamp to show positive and negative number, in order to measure my production of my sol-ark … Basically need to 2 CTs in front of the inverter, and 2 CT on the subpanel/protected feed,  at night this should show cancel each other out in the calculations. however at day it should calc a generation amount even if not sending it back to the grid.

This is a huge want for me too!

With my setup I have 2 AC to DC chargers tapped into my 240v (2x 120v) live microinverters lines so that I can show reduced production. Due to the absolute values for solar, it shows production when I’m actually in consumption thus breaking all my solar smart plug automation.

It essentially renders all my emporia stuff useless.

I get the same thing from my inverter too which is in my garden annex. Here is my setup video of the  Vue Gen  2 https://youtu.be/MXnLH4wHcEU

Can Emporia please give us an Honest answer on this.

From the very beginning we were told the CT used on the solar input are bidirectional, and that eventually the Software would be able to read the sign and report it correctly.

It has been years and still no change on this issue which is a major drawback for solar users.

@emporia, have you given up on this feature, or is there a real short-term chance it will be done?

Just tell us the truth 🙂

Appreciated, and thank you for such an otherwise great product!
