Figure 4-6 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.
2.
When solar power is unavailable, the power source preference sequence is grid >
battery. When solar power is unavailable but grid power is available, grid power is
supplied to loads and batteries. When both solar power and grid power are
unavailable, batteries supply power to loads.
Issue 03 (2022-10-28)
When both solar power and grid power are available and batteries are fully
charged (100% SOC), solar power is preferentially supplied to loads. If solar
power is insufficient, both solar power and battery power are supplied to
loads. When Discharge DOD reaches the preset value, grid power is supplied
to loads, and batteries are charged by solar power and grid power.
When solar power is available but grid power is unavailable (due to power
outage or abnormal grid), if solar power is sufficient, it is supplied to loads
and batteries; if solar power is insufficient, solar power and battery power are
supplied to loads at the same time.
