On AC power Cerbo GX not properly registering AC consumption from grid.

Dual Multiplus-II 3000/12/50a 120x2 in parallel

Cerbo GX with GX Touch.

I have the rooftop air conditioner running a few TVs on and some lights. But am only reading (as you can see in the photo 248w. I can also turn on the microwave and a heater and it doesn’t seem to change much. How can I get the AC to show proper usage?

Thank You in advance.

I am having the same issue. Looks like there are several related posts on this problem:

https://community.victronenergy.com/questions/94484/inverter-not-showing-ac-loads-on-vrm.html

Can someone from Victron please shed some light? Is this a hardware problem or a firmware issue or configuration?

Any update to this? My brand new quattro isnt reporting even the heaviest of AC loads, and there is a completely wrong AC input value.
