Does the 3000x have a true pass-through?

Does the 3000x have a true pass-through?

What I'm most interested in is if the inverter power draws from the yeti battery or the car link integration kit when the car is running. I saw in another post that the MPPT or car integration link directly provide passthrough power to the inverter

Here's the post referenced https://community.goalzero.com/discussion/127/does-the-yeti-6000-act-like-a-ups-and-power-directly-from-ac-electricity-when-available#Comment_725?utm_source=community-search&utm_medium=organic-search&utm_term=pass-through

What I am hoping is that equipment plugged into the AC inverter is being powered directly from the high power input of the car integrator as a passthrough when the car is running, versus running off of the yeti battery while the integrator is charging the yeti battery
