Zero export inverters are grid-tied but monitor the meter/CTs for load changes in order to curtail solar production/shift it to battery charging. I think they can technically backfeed a little bit if load is suddenly dumped depending on the inverter response time. Some have a secondary hard disconnect for additional protection. https://knowledge-center.solaredge.com/sites/kc/files/feed-in_limitation_application_note.pdf https://knowledge-center.solaredge.com/sites/kc/files/feed-i...
