Figure 5-8 Solar-grid hybrid scenario network diagram (multiple products
connected in parallel)
In the solar-grid hybrid scenario, the power system works circularly as follows. The
power source preference sequence is solar power > grid > battery.
1. If both solar power and grid power are available and batteries are fully
charged, solar power is preferentially supplied to loads. If solar power is
insucient, both solar power and battery power are supplied to loads.
2. If both solar power and grid power are available, the grid power is supplied to
loads and solar power charges batteries when batteries discharge to the cut-
o capacity.
3. When solar power is available but grid power is unavailable, if solar power is
sucient, it is supplied to loads and charges batteries; if solar power is
insucient, solar power and batteries power loads at the same time.
4. When solar power is unavailable but grid power is available, grid power is
supplied to loads and charges batteries.
5. When solar power and grid power are unavailable, batteries supply power to
loads.
