Charging EF Delta Pro from a second Lifepo4 bank via true sinewave inverter doesn't work?

DISREGARD THIS POST - See my own reply below....

I'm a newbie with the EF DP + Extra Battery.
However, I have years of experience setting up my DIY array and lifepo4 system for endless dry camping.
I have two inverters: Xantrex XM1800 Pro (ModifiedSinewave) and Xantrex Freedom X 3000W Truesine (Truesinewave)
They are connected to 4 105Ah Lion Energy 1300UT's in Parallel.
I have two separate arrays providing charge to the Lion bank (long story on why two) through 2 Outback Flexmax 60s.

The Issue:
When I attempt to charge the DP via AC from EITHER Xantrex, I can hear a relay click every two seconds or so and it won't begin charging. I've set the charge on the DP to as low as 300W and it still won't allow it.
I connect the DP to a typical wall outlet at home and charging is just fine.

I suspect that the DP is not seeing an earth ground or maybe it *is* seeing a bonded ground?

What would you suggest as a next step in order to get the DP charging off of my existing RV DIY system (which has tons of extra solar to spare)?

Thanks!

Ugh! And it was my first post in this group too!... :)

My sincerest apologies... No, the EF DP was NOT plugged into the Pure Sinewave inverter when I though it was. Shame on me for only using my own diagram where the outlet was drawn connected to the wrong inverter.

Once I plugged in the the right one, the DP started charging right up.
