Enclosed trailer 110vAC / 12vDC solar powered setup to power lights and accessories

I spent a lot of time trying to find information on how to install a battery system to run both 110 as well as power my 12v LED interior lights when not connected to the vehicle. Hopefully this helps explain a few things that I found confusing.

The basic premise is as follows:
- I have a deep cycle battery that sends power to an inverter for 110v AC and to a fuse block for 12vDC
- The fuse block is connected to both positive AND negative battery terminals with 8 AWG wire
- The battery is grounded to the frame to complete the circuit for 12v
- From the fuse block, I run neutral only to my DC devices as the block is now grounded via the battery and the devices (in this case lights) are individually ground to the frame.
- The inverter is connected to the battery with 4AWG cables and must be within a short distance to minimize power loss, and the positive has a fuse (175w)
- The battery is charged in some manner. In my case, I used a solar system, but you can use shore power or a battery charger, or even trickle charge via the vehicle if you have enough batteries to store your power.
- The solar panels are connected on the roof to extension cables that are cut so you can customize the length and attached to the solar connector panel.
- The solar connector is connected to the battery with 8AWG wires

The battery should now have the following connections:
- Positive:
4 AWG cable (with fuse) OUT to inverter
8 AWG wire OUT to fuse block
8 AWG wire IN from solar connector
Negative:
4 AWG OUT to inverter
8 AWG OUT to fuse block
8 AWG IN from solar connector
8 AWG GROUND to frame
