3.1 TOU (Time of Use) Mode
In the daytime, the surplus PV power can be sold to the grid or used to charge
batteries. At night, batteries are charged from the grid when the electricity price is
low. Batteries discharge in the morning or at night when the electricity price is
high. In the TOU mode, you need to set the battery charge and discharge periods.

3.2 Green Mode
In the daytime, the surplus PV energy is used to charge batteries. When the
batteries are fully charged or reach the maximum charge power, the surplus
energy is sold to the grid. (The batteries cannot be charged from the grid at
night.)
