Sounds great!... How about some pictures of the Outside unit?Just an FYI. I have installed a Pioneer 12k BTU 22SEER 120VAC Split unit in our 2007 Winnebago View 23J. Hung the outdoor unit on a strut frame at the upper left rear of the RV above the spare tire. The indoor wall unit is just inside on the rear wall above the bed. The 12K is just big enough to keep it cool enough to sleep at night when it is crazy hot (90F+), 9k would not have worked. Works just fine off-grid on the 3000W Xantrex inverter and 1680Ah (20kWh) LiFePO4 bank. After getting up to speed it generally draws 200W-400W when idling.
Did you go with the Cassette Inside unit (link below)?
Wow... 1680Ah LiFePO4!... Is that a typo? (I presume you built the battery bank?)
What's your Solar capacity? (How are you charging the battery bank?)
