Happy Breffast!
Only one leg of your system is working.
50A RV have two legs to the AC panel. They are typically fed by split phase 120/240VAC power from a 50A shore power receptacle.
Your inverter only outputs 120VAC. I only see L, N and G into what appears to be a NEMA 14-50R plug.
This is how they're wired:
X is L1 and Y is L2 when fed by split phase.
Since you clearly don't have 120/240VAC split phase output, you can't properly feed the plug.
If that plug had a red wire that you cut, Y is dead, and only the things powered by X are live.
Had you used a 30A receptacle and then plugged into it with a 30-50A adapter, the adapter shorts L1/X to L2/Y, thus providing:
0V between X and Y (no 240VAC input). X and Y both have 120V to N, BUT they are fed the same line, so they are 0V to each other.

Wow! I really appreciate you taking the time explain that to me. I understand now. I’ll get a 30 amp receiver to attach to my solar generator n use my 50-30 amp adapter. Thank you sooooo much!! ???

That's exactly what I did on my original ghetto system...
