Shunt showing charging when actually discharging

So everything was working fine for a couple of years and all of a sudden my shunt is showing charging but the inverter is running off the battery. Inverter is stating -250W but shunt is showing a 170W charge. This might explain why I was getting low voltage at 20% SoC left. Anyone know why all of a sudden this shunt would do this?

Hi Tweekzilla,

Do you have your shunt mounted in reverse?

Could you share a screenshot of your Shunt settings page?

Keen to get to the bottom of this one!

It’s definetly not reversed - It just looks like an offset that has appeared. It’s worked fine for a couple of years without any need to update or change anything. I’ll get a screenshot when I get home
