Inverter/solar install questions

I have the Magnum 3012 inverter and as suggested a sub panel was added. The new panel had the main, inverter, hot water moved to it making the original the sub panel.

The last time I hooked up to a power pole (50a) I would just flip the hot water switch on in the main panel. This is the hybrid unit so on the me-arc I would adjust the incoming ac to 50a to power everything off of the power pole.

Like yours the panel is in the middle of trailer and the inverter, batteries, pt controller are in the front compartment.

OK, so that's essentially my original plan, which is in part based on making as few changes as possible to the existing wiring. I need to put the new main panel in the front storage compartment, which is why I was thinking of moving the plug rather than make a new run all the way from the rear to the front of the RV.

So my version of this plan would be:

1. Move plug from rear to front. There is already a properly sized hole where the vent from the original flooded battery was.

2. New panel with main, ac, wh, and 30A breaker to inverter AC input in front.

3. Current run from rear plug to main becomes the run from the inverter AC output to the old main panel, now the subpanel.

4. Old converter is disconnected and removed as Magnum 2812 is an IC.

5. Main breaker on old main panel switched to 30A to match output of inverter.

6. 400A fuse on DC wire from inverter to batteries.

7. #0000 wire connects inverter to batteries.

I am planning on mounting the inverter on the bottom of the front storage compartment, and I'm thinking of adding some kind of heat sink/spreader under the base. Since the bottom of the compartment is metal, it will spread the heat, though it could get quite warm. I might use the small output circuit from the solar charge controller to power a small exhaust fan, something like a 120mm computer case fan.
