Three Work Modes
1.When PV, Grid, Battery is available:
Solar energy provides power to the loads as first priority; if solar energy is insufficient, battery supplies power at the same time;
if solar energy and battery are both not sufficient, the grid supplies power at the same time.
2. When PV, Grid is available (without battery):
Solar energy provides power to the loads as first priority; if solar energy is insufficient, the grid supplies power at the same time.
3. When PV, Battery is available (Grid is disconnected):
Solar energy provides power to the loads as first priority; if solar energy is insufficient, battery supplies power at the same time.
1.When PV, Grid, Battery is available:
On charge time, solar energy charges battery as first priority, and supplies the loads and delivers power to the grid if sufficient.
On discharge time, solar energy provides power to the loads, charges battery, and delivers power to the grid at the same time.
In the period of no charge or discharge, the solar power supplies the loads at first priority, excess energy to the grid.
2. When Grid, Battery is available (PV is disconnected):
On charge time, grid charges battery and supplies power to the loads.
On discharge time, battery supplies the loads as first priority, and delivers power to the grid if sufficient; if if battery power is
insufficient, the grid supply the loads at the same time.
1. When PV, Grid, Battery is available:
Solar energy charges battery as first priority, and supplies the loads and delivers power to the grid if sufficient;if solar energy is insufficient, the grid supplies power at the same time.
2. When Grid, Battery is available (PV is disconnected):
Grid supplies power to the loads and charges battery at the same time.
