In the winter I generally don’t use shore power. I’m getting the rig ready for the spring camping season and I’m seeing there is now no AC current/wattage in or out reported when the Multiplus is on. When it’s inverting it reports AC output fine. I have checked AC power is working in the rig. I’ve confirmed AC is coming in through shore power. Since the last time I saw it reporting correctly I did upgrade the firmware on the Multiplus from version ‘508’ to version '552 and have upgraded the Cerbo from version ‘3.50’ to version '3.52’. I’m observing this on the touch display, in VRM, and in VictronConnect. I hope this is a software issue.

Anyone else seen this or able to suggest further troubleshooting steps?

I’d suspect the current sensor of the input circuit , if you have the version with the 3.5mm plug you might try to check there, when the internal switch is dead this could be the source.

I guess “inverting” the ac current is just calculated from the dc input.

Try turning everything off at the shut-off and then restart everything.
