During the day PV powers the house and charges the battery pack. If you’re not using all the electricity that the solar PV system is generating, then the system will ensure that any surplus energy is used to charge the battery pack. Once the battery is fully charged, if there is still more solar electricity being generated, this will be exported to the grid. At time of low solar generation (night or cloudy day) the solar PV panels have a reduced or zero output, but the battery system can discharge the stored electricity, providing you with renewable-generated electricity at no additional cost. Once the battery is discharged, if you need to use more electricity, you buy it from your electricity supplier.
