Excess solar power question

Theoretically if I have a solar panel array that is 13.5 KW, and battery storage for 45 KW. Once my batteries are full do I have to have a energy dump for that electricity, or will my mppt/inverter just essentially disconnect the panels?

I understand the idea of having an energy dump such as a water heater or similar- but say I'm on vacation and everything tops up due to low use, is this a situation I need to be concerned about or do I just "lose" that energy?

Looking at designing an off-grid system for my house, but wanting to make sure I cover all of the bases. I'm okay with losing excess energy to attempt to cover all of my uses as best as I can, I just want to make sure I'm not doing something dangerous where something's going to catch on fire due to excessive energy with no place to go for it.

This is a plot of a AirThings Corentium Home 2, Placed Feb10, and plot starts on Feb 11 - Today (so about 80 days of data)

Is this something I should take action on? If so how high of a priority?

Location is in basement, about 36" off floor in a partially finished basement. Currently no one sleeps in location, however one individual does want to change from a much smaller room to this one.
