A. Solar energy provides power to the loads as first priority, if solar
energy is sufficient to power all connected loads, solar energy excess
power will provides to charge battery, and then redundant power will
feed to grid.
B. Solar energy provides power to the loads as first priority ,if solar
energy is not sufficient to power all connected loads, battery energy will
supply power to the loads at the same time.
C. Solar energy provides power to the loads as first priority ,if solar
energy and battery are not sufficient to power all connected loads, utility
energy (Main Grid) will supply power to the loads with solar energy at the
same time.

2 .When PV, Grid is available
（
without battery):
A. Solar energy provides power to the loads as first priority ,if solar
energy is sufficient, the excess power will feed to grid.
B. Solar energy provides power to the loads as first priority, if solar
energy is not sufficient to power all connected loads, Grid energy will
supply power to the loads at the same time.
3 .When PV, Battery is available
（
Grid is disconnected):
A. Solar energy provides power to the loads as first priority ,if solar
energy is sufficient to power all connected loads, solar energy will
provides to charge battery.

1.When PV, Grid, Battery is available:
A. On charge time, solar energy will charge battery as first priority. The
excess energy will supply power to the loads.If solar energy is sufficient

to supply loads and charge battery, and If there's still some extra energy,
then the excess power will feed the power to grid
.

B. On charge time, solar energy will charge battery as first priority.then
the excess solar energy will supply power to loads.If solar energy is not

sufficient to charge battery and supply loads, grid will supply all the
connected loads with solar energy together.

some extra energy from solar energy, then the excess power and battery
will deliver the power to the grid at the same time.

B. On discharge time, if load power is less than battery power, battery
will supply power to loads as first priority, the excess power will be feed
to grid.
