I have the same inverter. It does the same thing. I think it inverts the DC always. I don't think it has passthrough capabilities at all.

My is flaky in that when shore power (gen set or grid power) it will turn off the inverter and restart the inverter constantly. The charge side is not having any issues.

That leads me to think the inverter side and the charge side have very little communication with each other. JMHO

I have a new inverter Victron to replace the Outback.

it says that it has a pass thru in the book.  The red light that is on was an old over temp error that is stored in the system that I have to go into the advanced settings to remove.
