Quattro Inverter in Passthru

Hi There,

I have a Victron Quattro system that goes into "passthru" and then stays there for extended periods of time. I have noticed that this is somehow related to communication with the ET112 single phase grid meter which is connected to a color control gx.

Enabling and disabling the energy meter as well as restarting the color control solves the issue consistently.

Below is a list of components with the current firmware versions

Color Control GX - v2.54

5kVA Quattro - 2657430

Freedomwon Battery Monitor - v6.8

250/70 MPPT - v1.50

3.6kVA Fronius Inverter - 3.13.2-2

Please let me know if I'm missing something.

Best Regards

Riaan

Firmware version update on the color control solved the passthru issue.

Hi @Riaan Barkhuizen

As you've noticed, a communication error between the grid-meter and GX device can cause this, as also mentioned in the manual (Q4 of the faq):

so start with the grid meter / cabling / etc.

Just wondering why everything works after restarting cgx. If it was a cabling problem, probably it would stop working completely. Could it be that the energy meter stop communicating. I did see this once before, but that time the meter would not communicate at all. Is there a way to test the cable and the meter? Or is the only way to change them out and hope for the best?

Same problem here now. After posting the solution for my Passthru issue I now have this happening every morning! It is very clear that the pretty lights in the USB connector from the grid meter are green and red. When this issue occurs mine is green but no red. Is this significant?
