Why my battery is still not charged from grid even I enable the function of "charge from grid"?

You need to the follow setting steps below:Path: Main menu—>Setting—>User Settings—>Self-use—>Chrg&Dischg PeriodSetting: set a forced charge period start and end time, for example: 01:00—5:00.Notice: 00:00—00:00 means no charging time period and only PV can charge battery.Then confirm the maximum charge current is not set to 0.
