For me, the SUB prioritization and energy mixing function only works while the battery is charging (LI Battery from GROWATT model ARK 2.56KW on CAN) . When the battery charge reaches 100% the current from the solar panels becomes insignificant when mixing (from 3600W available from 8 solar panels is used in the middle of the day with full Sun - 6-8W).
When I change settings to SOL or SBU, it immediately takes 1800-2000w from the panels depending on the load and zero from the Grid......
I asked Supergeek to send me the new firmware and I hope that this problem will be solved ...
