Work Modes
Hybrid Inverter provides multiple work modes based on different requirements
Work modes: Self-use
1.When PV, Grid, Battery is available:
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 reduntant
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.
B. Solar energy provides power to the loads as first priority ,if solar
energy is not sufficient to power all connected loads, battery energy
and solar energy will supply power to the loads at the same time.
