For your inverter to charge two 12 volts 650 amper hour, it will require a current between 7amp s to 15amps. So i will recommend a 60amps circuit breaker. The best type should be such that allows a firm contact so that there is no voltage drop. An example is any type that will need you to use a cable log. Any connection via cable logs provides a very firm contact.Note that a lose contact will reduce the run time of you inverter and will make the charging time to be longer than expected.

breaker must have a DC rating if not it maybe will not be able to protect
