Are you plugged into shore power, or is the generator running? If so, 120 volts in to inverter and 120 volts out of the inverter is normal.

Magnum charger is charging so again normal.

There may be a 100 amp breaker on the 12 volt cable connected to the inverter. It will not interrupt 12 volt house power.

There may be a 100 amp breaker on the 12 volt cable connected to the battery. It will interrupt 12 volt power to the house.

There may be a 100 amp breaker on the Magnum inverter/charger.

House power shut off near the door may be "off".
Disconnect relay may be defective.
Cable connection may be loose, corroded, or burned.
Battery disconnect next to the battery may be "off".
Main fuse or circuit breaker blown next to the battery.

Inverter/chargers run independent cables to the batteries. They charge the batteries but don't supply 12 volts to the house.

House supply will have a fuse / breaker near the battery, then a battery disconnect solenoid, then supply the house power.
Cables will be smaller then inverter cables.
