I've purchased quite a few more parts now. I ordered a new Ryobi 2300 generator. I found out it accepts an 18v One+ battery (which I have a dozen of, it seems lol) and I can remote start it from my phone app. I also got a Victron Smart Shunt, that im going to try and mount it inside the battery box if I can simply enough. I also got a Raspberry Pi 4 and going to get the Solar Assistant software so I can monitor it better than the garbage WatchPower app.
I also am going to be doing some serious reconstruction on the compartment the inverters/batteries are going into. Im going to cut out the factory floor (18ga thin Steel), and make a custom drop floor, that is roughly 6" lower, which will accept a decent sized Mini Split ODU. ? just planning ahead if I do a mini split, I want to make it as easy as possible. Im also cutting a nice mount that will hang both inverters off of, as well as the 48v to 12v Buck Converter and some other misc odds and ends, like bus bars, Class T fuse etc.
I also ordered 3x RV Airflow units, to improve the efficiencies of the factory AC units. I figure I might as well get the most out of what I have. Even when/if I do mini splits I can sell the AC units and these RV airflow inserts.
Update on the LV6548. Since I ended up taking apart the entire unit to try and diagnose further, they will just send me the main board directly and I will install it. I also paid an expedite fee of $70 to have it within a week, but we'll see. I also got confirmation from Ian that my new unit is being unloaded in LAX today and it should be getting shipped out soon as well.
Lots going on, we'll see how it all works out.
