Hello im new to solar and have been doing as much learning as possible but I was wondering if someone could shed some light on a question. Currently I’m looking to develop an off grid system without net metering or export and exploring my options. Essentially while I’m interested in off grid options it seems hybrid systems offer more output/deatures in single units however often require supply/line taps or large backfed breakers. My main panel is 200amp which feeds a 100amp MLO subpanel. I believe the bus bar is 200amp rated. Is it possible to use a smaller 40amp breaker for back feed into the inverter which then would connect to the sub panel via transfer switch/interlock with the 100amp? I currently do not have a net metering contract and would be not interested in exporting to the grid.
