I am installing a solar system on my travel trailer. It is a slightly modified version of Will’s classic 400 watt system. Since my travel trailer already has a 12 volt system, I only needed to add 110 outlets for perhaps an ice maker, a TV and or coffee maker when dry camping. I was hoping someone with expertise in solar and RV’s could review my schematic and offer any advice that would save me from say burning down the house or trailer. Please see attached JPG for schematic. Thanks in advance!

2200 ac watts / .85 conversion factor / 12 volts low cutoff = 215.68627451 dc amps
215.68627451 dc amps / .8 fuse headroom = 269.607843137 fuse amps.
2 awg is way too small for the critical path.
2/0 awg pure copper with insulation rated for 105C is the minimum.
