Victron Overload Light

Victron Phoenix Multiplus 12v/2000/200

My motor has been getting rebuilt so I'm tied up to a dock. A couple of days ago we plugged in the shore power and I fired up the Victron for the mechanics use. It worked fine and I went home. I checked in yesterday and it wasn't functioning properly. If I disconnect the shore power the inverter kicks in and works but with the shore power on the charger will try to engage during startup but it will kick out and the overload light comes on. It does this with the rocker in inverter/charger or charger position. I've hooked the shore power up to my Honda 2000i and it behaves the same way so it's not the dock power that is the issue.

I haven't opened it up yet, I wanted to see if anyone had any ideas first.
