2.5 How it works

- 6 -
Morning
Afternoon
Optimized self consumption will be
achieved. ESS are used to store the
excess energy produced by PV system.
Extra energy will be fed into the grid
when ESS are fully charged and system
has already meet its load requirement.
Evening
Night
ESS will power the AC load when the
sun sets.
If the ESS capacity is insufficient to meet
self consumption requirement, electricity
will be obtained from the grid.
