I have just installed my first system so this is a sanity check. I understand a lot technically and mechanically about the systems and why different components are used and wire sizing etc. which I know prob makes me dangerous at this point. The system works, and works great, I am however confused at one thing that I am experiencing. Unfortunately I don't have a current diagram but I will try and explain.
My system is 12v, I have a Xantrex 2000w inverter, Victron Shunt, Lynx Power In, and 100/50 smart MPPT, and 300ah (soon to be 400ah) of LiFePO4 battery.
I have the lynx power in converted to allow for fuses on the output/input side (4 connector side) like a lynx distro has and I have fuses there for the inverter connection that is 4/0 cable and fuses for the 12v to the PowerCenter. I connected my battery input on its main side connection of the power in.
The path the electricity has to run from battery is this.
Positive connection:
All wires stay cool maybe slightly warm (but I am in AZ and its already over 100 so might just be ambient temps). But the fuse and the battery disconnect get hot. Not crazy hot or glowing red. I believe they should stay cool from what I have read. I have checked all connections and they are tight, I am afraid to crank down on them as I dont want to break the fuse holder etc... How tight should they be, is there a specific torque?
Now to be clear, this only happens when I run the AC for a while, i.e. 1hr or more (yes the 2000w inverter runs the 14500btu Furrion AC just fine with its micro-air softstart, just cannot run any other AC item at the same time). Running the microwave or a hairdryer does not cause this, but they do get warm on those. Everything else works fine, the transfer switch on the inverter seamlessly switches between invert and 120 shore power when plugged in. When plugged in to shore the batteries charge via the power center just fine, no loops or grounding issues etc.. I have just this one concern.
Is this normal? What am I missing or should I possibly replace something?

Positive connection:
- The lynx is directly connected (via bolt/nut) to a seaflo battery switch (https://www.seaflo.us/product/batte...id=fb6698fccd3d11eca52beb764e977f4b#undefined)
- The switch then connects to a blue sea 250amp T Fuse via a 6" 4/0 wire, this is in a blue-sea t-fuse holder/mount with cover
- From the fuse it then goes down to my battery positive connection via 4/0 cable.
- The neg side of the lynx in connects to a Victron shunt via a 6" 4/0 cable
- The shunt is then connected to the battery via 4/0 cable
