We have what is called a hybrid converter. It handles power flow to and from the grid, to and from the battery, and from solar. Think of it as a a multigang multiway switch.
1. If full sun, solar output charges the battery, excess powers the house, and excess beyond that goes back into the grid.
2. In the evening, or really no sun at all, the 9kVA battery powers the house. If the battery gets depleted, the house is powered from the grid.
3. From 0030 to 0530, at 8.5p/kWh the battery is charged, we delay run the dishwasher, and we charge the eV.
4. If there is a power failure, and it is not sunny, you're at the mercy of the battery. The only power hog in our house is the electric oven. But power cuts are only for a couple of hours max.
