Hooking up a solar charge controller and inverter

[padlin]

Don't know if I can explain this very well, but I'm looking for the best spot to connect the +12v for solar and an inverter.

If I followed the existing positive (+) circuit right, the + battery terminal goes to the 30A inline breaker, then to the disconnect switch (I believe the switch is only on the 6 volt battery systems) then to the converter. I currently have the + of the solar charger connected to the non battery side of the disconnect switch so the disconnect shuts down the solar too. Thoughts on if this is best?
How about the battery temp sensor, does it attach to the batteries or just dropped in the battery box? All the prints I see make it look like it's connected to - terminal.

For the inverter, I believe the fuse goes as close to the batteries as I can get it. If I keep to a single + battery connection, then the new fuse, 80 or 100A in this case for a 600W inverter, would go between the battery and the original inline 30A breaker? then the inverter + connects to the non battery side of the fuse? The 30A breaker would still protect the wire to the disconnect while the fuse would protect the larger wire to the inverter, I think. Thought?
