1. Self-Use Mode Logic (Maximize the usage of PV):
PV Power Using Priority: Load>Battery>Grid
Load Support Priority: PV>Battery>Grid
Battery Charging Power comes from PV.
(If “Charging from Grid” is allowed, it can also come from Grid)
If “Time of Use” is “Run”, the logic will follow the charging/discharging settings and time settings
as defined in “Time of Use”. For those undefined period of time, it will still follow the Self-Use logic.

NOTE:
Unless specially required, it is suggested to keep the "Charging from Grid"
as "Allow". If it is set to "Not Allow", the battery force charging logic will be
affected and may lead to a fully discharged battery.
2. Feed In Priority Mode Logic (Feed the excess PV to Grid in order to gain subsidies):
PV Power Using Priority: Load>Grid>Battery
Load Support Priority: PV>Battery>Grid
If “Time of Use” is “Run”, the logic will follow the charging/discharging settings and time settings
as defined in “Time of Use”. For those undefined period of time, it will still follow the Feed in
Priority logic.
