Fuses/Breakers
Looking to add fuses/breakers on my setup: Batteries: 2x6 volt T-105 Solar: 2x100 watts, 30 amp PWM controller, #10 AWG wire panel to controller, #10 AWG to battery. Inverter: 1000 watt PSW, #4 A...

For the 4 AWG wire to the inverter, 100A might be appropriate, and probably a slow-blow fuse or thermal curve circuit breaker would be most appropriate. This wire seems rather marginally sized for a full 1000W load from the inverter.
The OP hasn't indicated how long his battery > inverter cable runs are so it's difficult to say whether 4 gauge was appropriate. When I installed my own 1000 watt inverter in our trailer's front pass through storage compartment I required 6' cables to reach the battery so I used 4 gauge cables which this Blue Sea DC Wire Gauge Chart indicates as suitable for my intended maximum load of 70 amps. I wired it in using an 80 amp fuse and it's worked out just fine.
