A 110 amp fuse should work well. The T-Fuse would replace the 300A breaker. TFB1-110, 110A Class T Fuse Kit | DonRowe.com The TFB1-110 offers 110 amps of over-current protection and provides safe operation of your inverter. www.donrowe.com Don't see a need for the breaker between positive 400 amp bus bar and inverter/charger. Probably bump the breaker between positive 400 amp bus bar and Solar Charge Controller to 75 amps. Need a breaker between positive 400 amp bus bar and 24V to 12V converter. Need more info on solar panels. Voc, amps watts of each panel. How are the solar panels wired? Serial or Parallel? Looks like mostly Victron equipment is pictured, which is a good choice. Stick with Victron for the Solar Charge Controller (better than Renogy)
