Smart shunt showing very low input going into batteries

My Victron display is showing the batteries are only getting 0 to 75 watts.. They are at 63%, yet the panels are producing 1418 watts. There is nothing on in the house right now. It has been working flawlessly for a couple of months not sure what happened. My display on my Victron smart solar charge controller is showing 53 A 26.8 V. Is this just a display error on the control panel? Is there an issue with the smart shunt?

    If the panels are producing 1418 watts it has to be going somewhere.

    I agree, I believe it’s just the smart shunt. Think I’m going to shut the system down and start over.

    Ok…I’m embarrassed…mystery solved. My wife had our golf cart plugged in….and started the crockpot without me knowing. Golf cart charger was pulling 660 watts alone…..All good now!

    Been there, done that.  Look at one of the status meters and wonder where the heck the power is being used!!!  Oh yeah, I just plugged in the kettle, or toaster etc.  Short term memory ...something something something.
