I'm by no means an electrician, but something about your proposal sounds like there might be an electrical issue. You would be drawing off the 12 volt bus to provide 120 volts with your inverter. If you wire the inverter output to your 120 outlets you are also connecting to the input (120 volts) of your converter. Said converter is providing 12 volt charging to your battery system. Something about this circular electrical connection sounds troublesome. As you draw battery voltage down with your inverter, the converter senses that and tries to recharge the battery using 120 volts supplied by the inverter. At the very least you should turn off the converter circuit breaker to break that circular (perpetual motion?) arrangement. Anything that relies on the user remembering to turn things on or off is an opportunity for errors that could result in electrical damage or fire. I would just have an electrician look things over.
