Used the same breaker for the fridge and inverter because both are never on at the same time.

Didn't worry about fusing the separate wires because the run to the connector is only a few inches. Have thought about changing from the 7-pin to a
Anderson SB175 for the power, but didn't like the idea of two connections. Will re-evaluate the fire risk.
