Hi Derek,

If you use the Sunsync or the Deye, and you rewire your DB into essential and non essential loads, where essential loads are fed through the inverter, then during the day if there is excess solar energy, that means that the batteries are fully charged, and the essential loads are drawing less energy than than is available from solar, then using the installed CT just after the DB incoming isolator, the inverter then feeds the excess available energy back into the non essential loads to reduce the energy from the grid to almost null if there is an over supply of solar energy..

Its almost like having the inverter on the input of the DB, but not requiring to size the inverter for the full DB load.
I think this is called backfeed.
