Under the sink, behind the fridge, in with the water pump etc is all good.

If you want to switch manually so to speak and use the amazon plugs inside a compartment that is fine. Attach a male plug to the main feed wire to the panel and a female connector to the other side that connects to the inlet. Attach a second female connector to a cord that plugs into the Bluetti.

What do you mean by just plug it in? Plug what to what with what? Here are a few transfer switches: https://www.bestconverter.com/30-Amp-Transfer-Switches_c_182.html Yes they are a bit bulky.

When you cut the wire from the inlet to the panel.... the proper thing to do is install a transfer switch. Add a second inlet to the Bluetti. Of course if the Bluetti can sit outside, a simple adapter from Amazon works fine. Bluetti goes direct to the existing inlet.

Have you adjusted the full charge setting in the BMS? Although if the battery reaches the selected full charge and presents the battery as 100% that actually seems correct even if the definition gets the battery to say 95% of absolute capacity. Still it is 100% of what will be utilized...

No absolute need for the monitor. If you want it or it seems to have value to you, as it does for many, then go for it. My Overkill BMS always seems very accurate.

12v x 1200 a/h is the same energy as 48v x 300 a/h. The 12v will drive the inverter just fine without the multitude of 12-48-12 complications. BTW my 12v 2000w Go Power runs the RV air just fine. Although is uses a lot of energy so usually I look for a place to plug in if I need cool air for...

12.45 per foot. How much you need? https://nassaunationalcable.com/products/2-3-w-grnd-nm-b-600v-stranded-black

State of charge is interesting. What is the actual voltage of each battery? Use a separate voltmeter. Have the batteries been through a charge/discharge cycle?

THHN will be very stiff. Will still take a lug and connect. Going to be an effort to get the wire bent to avoid stress on the component terminals.

I use a Meanwell NPB-450-12 as my generator is small and mostly charged with solar. There is a larger 1700 version. I don't think even 100 amps would hurt those batteries one bit.

My electrician just pulled #2 NM-B across my attic for a sub panel. It could take your arm off.

How will load dump work if the water is hot? Need two thermostat settings. May need a separate pre heat water heater to be left cold and only power with 120v. Existing can stay at 240. Space could be an issue.

Posts? There is a bar to bolt the lug to. I have an old discontinued Go Power 2000w sine wave inverter. But any brand will connect with 2/0. Quality 2/0 marine wire is good for at least 280 amps and a 2000w inverter will pull 170-190 amps as it approaches peak rated power. I installed 4/0...

2/0 feeds a 2000 watt inverter nicely on 12v. Probably go 4000w on 24 volts.
