Allow AC charging
In this situation, the battery can be charged both with PV and AC.
a)
Wealthy PV power
When PV energy is wealthy, PV charges the battery first, then meets the loads, and the rest is

b)
Limited PV power
When the PV energy is not enough to charge the battery, the grid energy will charge the battery
as supplement. Meanwhile, the grid energy is consumed by loads.
