First draft of my LiFePO4 system - your input appreciated

No fuse needed on two solar panels if the wires have ampacity to cary the max amperes of the panels. A switch is needed.
A fuse is needed for the inverter. All fuses should be sized to the ampacity of the wires being used, not the devices.
Provide some clamp support to the cells that the tops can not move.
You have done some neat work.
Thanks for the ideas. I do have a 150A fuse for the inverter (it may not be on the schematic, though). I thought I could get away with using the big zip tie to stabilize the battery tops. Each zip tie goes through the bottom of the case to use the case itself as an anchor.. Will reconsider using some threaded rod to clamp down. Glad you think it's neat. It got harder to keep the wiring neat as the box filled up.
 
OK done and looks good. :)

Two shunts seemed odd to me. I would fuse the batteries at 80% to 100% of the BMS rating.
