I am almost positive is cant back feed since the Progressive industries contactor is off when no shore power is detected and I do not have any power on L2 when on inverter power. When the AIMS senses no input AC it will supply AC to L1. The load created from the air conditioner shuts the inverter down so I am not worried about the batteries. They are also protected via the 300A fuse. Battery-300A fuse-cut off switch-inverter. I also have a catastrophic fuse on the positive side of the battery bank.

I went out and checked for back feeding just the completely rule that out. Nothing on the shore power cord. Another wrench in this is the sequence it starts up. It takes ~15 seconds once shore power plugged in for the progressive industries to send power to the coach (once it checks everything and then turns on the contactor). Then it takes and ~15 seconds for the inverter to switch from inverter mode to charge/bypass mode. So with my vast amount of patience , turning on the air too soon will run on batteries till either the inverter switches to bypass or is overloads and shuts down.

Is the fuse a slow blow type, to handle a surge.?
It was these https://www.amazon.com/gp/product/B076HMDJZH/ref=oh_aui_detailpage_o06_s01?ie=UTF8&psc=1
Here are a few pics of my install so far. The cables with electrical tape are from factory. I will be replacing them with proper connectors and heat shrink.

These site says a 3000W inverter should have a 400 amp fuse on 12V DC installations.

Fuses at 8.39 for 5 probably at not up to the job.
Here is a quality product.
