What you can do with PV tie in potentially is get the permit for the solar, connected to a very cheap grid tie inverter with no battery (maybe even get one off craig's list). You can even skip the PG&E interconnection fee ($145), my AHJ did not check that I applied for it.
And after you get sign off from AHJ swap in your EcoFlow if you want.
The issue with AHJ is that unpermitted solar panels stick out like a sore thumb.
When you move, put the cheap GTI back in place so you don't leave a hole there (which could cause some liability issues etc if renting, and similar issues if selling)
