Morning: low output, high demand
In the early morning, PV generation cannot meet the energy consumption, Sunways energy storage system will bridge the gap with the power stored in the battery in the previous day.
Midday: high output, low demand
PV generation is at its peak in the day time. But since nobody is at home and the energy consumption is very low, so most generated power will be stored in the battery of Sunways energy storage system.
Evening: high demand, zero output
The highest energy consumption in a day is at the evening and PV generates little even zero energy at this time. The Sunways energy storage system will bridge the gap with the power generated during the day.

* The grid feed in power for AS/NZS 4777.2 is limited 4.99kW & 4.99kVA & 21.7A.
** Max apparent power from the grid means the maximum power imported from the utility grid used to satisfy the backup loads and charge the battery.
*** The output power will exceed the rated value only when the power in the PV array is sufficient, and the duration of the overload is relating to the overload power.
