Work modes: Back up mode
Priority: battery>load>grid
This mode applies the area that has frequent power outages. And this mode ensures the
battery will has enough energy to supply when the grid is off.

when the grid is on, and it also allows to choose whether charge from the grid or not.

Work modes: FFR Use mode
FFR (Firm Frequency Response) is a service provided by energy users to National Grid,
which uses approved assets to quickly reduce demand or increase generation to help
balance the grid and avoid power outages.
National Grid needs help when there are large deviations in system frequency caused by too
much generation compared to demand or vice versa e.g. when a power station unexpectedly
shuts down. In such events, to ensure that generation and demand can be quickly balanced
1) Generated solar energy
2) Storage in Battery
3) Load consumption
4) Grid supply power
1) Generated solar energy
2) Load consumption
3) Self-use from battery
4) Grid supply power when the
battery capacity is not enough
