New Version Install flow
So I RE-DID ELECTRICAL FLOW INSTALL DIAGRAM WITH THE BEST REPRESENTATIVE IMAGES OF MY TRUE COMPONENTS I COULD FIND ONLINE. THESE ARE MY ACTUAL OWNED ITEMS ( A 2ND 24V 6KW INVERTER CHARGER & MINI SPLIT WAITING TO BE INSTALLED & ALSO A DIESEL HEATER & BATTERY PREPPING FOR WINTER... A 24/7 FULL TIMER RIG.

The diagram does not make much sense you have the positive and negative bus bars connected with 2/0.
Mystery DC coming from the AC panel to the MPPT.
A converter listed and a seperate charger. Why the andersons?
Need 3 class T fuses as close as practical to the battery terminal.
No detail on how your handling chanover to inverter and isolation of the chargers.
You have no AC passthrough or load management.
Where is your dump load? Something to do with excess PV production like running the water heater. This is a nice to have.
3x 12v batteries but your talking about 24v kit as well. Frankly would go 48v to reduce you spend on bus bars and wire, convert at your 12v distribution panel.
It's a van build where is the 12v starter battery maintenance? Where is the DC to DC to charge from the alternator.
Overall it's a pile on cheap components with no central monitoring/management. A single RV hybrid inverter would be far more useful as you would then have additive AC power and load management the UPS function is just a bonus. Wonky pedestals are a fact of life load management is huge there.
