RV Application - 2 ea multiplus II 2x120 Configure for split phase or parallel

Background:

Existing power into my RV can be:

Shore power can be 50amp 240vac split phase 180 degree, OR

Shore power 30 amp, single phase L1 and L2 tied together by dog bone adapter

Generator: GENSET ONAN 5500 watt

I have no load devices that require 240 vac.

I plan on using two victron multiplus II 2x120 units.

  • solar on roof is 2800 watts
  • lithium batteries 4 ea at 300 ah 1200 ah total
  • full compliment of victron components such as power in, lynx shunt, distributor, cerbo gx etc..

Just haven' t wired the AC in and AC out to the multiplus as of yet.

Based on the background info, which of the two configuration methods be best for this install?

Parallel or Split phase 180


Thanks to all in advance

Two @ MultiPlus 2x120 in Split-Phase configuration?
Kind of defeats the whole purpose of buying a Multiplus-II 2x120 in the first place?
And the MultiPlus-II can be very loud.
