But I think the circuit breaker that is polarity sensitive can't have current passing through it in both directions, right? The inverter/charger is one unit that will push power to the batteries to charge them when the generator is on, and pull power through the same wires from the batteries to invert to supply the loads. But that circuit breaker in the middle won't like that as far as I understand it, so long as it's polarity sensitive.They should be fused internally for any fault there.
The problem with batteries is a gazillion amps in a few seconds can dump through an unprotected wire. I ‘knew’ that but I learned here about 20kA discharge potential and decided that my ‘casual’ habits with batteries needed amending with energy-dense lithium chemistry batteries- because lithium is not only a delicious dessert topping, it’s a floor polish, too.
The one I'm looking at ... I don't know if it is polarity sensitive or not: https://signaturesolar.com/nader-dc-circuit-breaker-60v-200amp/
