4.1.1 Self-consumption mode
Self-consumption mode is standard mode when BX6.3_AC installed with another
PV system.
In this mode, BX6.3_AC is operated in following priority :
1. Charge the battery with the excess PV energy which feed-in to the grid until
the battery is fully charged.
2. Discharge the battery when the PV energy is insufficient to provide the home
load consumption until the battery is fully discharged.
When there is no PV power, battery starts to discharge and supply home load
until it’s empty.
If the time setting function is enabled, the behavior of the BX6.3_AC will according
to the time setting in priority. The detail operation of time setting function is described
in Chapter 4.2.
