I have a Charger 2 connected to my AC200L in a van. I’ve been told by Bluetti customer service that I should be able to reverse charge from solar (without needing an expansion battery). When I turn on the reverse charge, my solar input drops to 0 on the app - if system on/off is turned on. If I turn system on/off to off, it shows power (watts) at both the car battery and the solar input, but the little animation of which direction the energy is flowing is missing, and the car battery voltage drops almost immediately after it turns off (reaches 12.6v). Anyone else having success with reverse charging from solar without an expansion battery?

I’m pretty sure the reverse charging with the battery bank via p090a port, it’s very confusing. I originally thought my portable power station (elite 200v2) could reverse charge via PV port, but I was wrong and had to buy a used b230 to reverse charge via p090a port. It essentially forces you to buy the WHOLE ecosystem.
This is in their FAQ page, which is not linked in the listing.
“How can I use Charger 2 to reverse charge a vehicle battery from the
power station?
The power station only supports reverse-charging the vehicle battery
via the P090A port, through Charger 2’s ALT port.”
