EcoFlow Rectifier

I only have two 400w EcoFlow solar panels wired in series routed to PV1 of my solar cutoff switch that came with my DPUX. I have had both the PV1 and PV2 connected to my PV inputs of my DPUX even though I only have panels wired into PV1. As far as I can tell, in the time I’ve been doing this everything has worked fine and the charging has been as I would’ve expected given the placement of the panels in my yard.

My question now is should I take both outputs from the cutoff switch and plug them into the two inputs of the rectifier and then take both the outputs of the rectifier and plug them in to the Delta Pro ultra X? If so, where would I set the switches of the rectifier? I’m worried that if I set them both to PV that the output will not be high enough to turn on the charging of the DPUX? Should I just keep input and output 2 disconnected?

FYI, the only reason I bought the rectifier was because eventually I want to be able to buy a generator and plug it straight into the rectifier rather than dealing with all the nonsense of plugging it into the inlet box of the smart home panel three and all of the associated limitations with charging batteries by going that route.

I’ve also thought that I might just keep the wiring as it is right now and then when I do need to use a generator, I could just unplug all of the solar, plug the generator into the rectifier, and then plug both of the outputs from the rectifier into the DPUX.

Thanks in advance!
