2.2 Operating mode
The inverter status can transfer automatically between grid-connected and off-grid mode according to
grid status. In the grid-connected status, there are four operating modes: self-consumption priority,
battery storage priority, peak shaving and energy shift scheduling. When grid is abnormal or failure,
inverter will work in the off-gird emergency mode.
Self-consumption priority
When the energy generated by PV array is sufficient, PV array will supply power for load in advance,
the remaining energy will charge battery. If there still has remaining energy, it will be supplied for grid-
connection generation. When the energy generated by PV array is insufficient, PV array and battery
will supply power for load in advance, as shown in Figure2-4.

Self-consumption priority
Battery storage priority
If battery doesn't charge fully, PV array and grid will charge battery fully in advance to meet the
emergency power requirements of key loads. When the energy generated by PV array is sufficient
(more than charging energy), it will charge battery in advance, the remaining energy will be supplied
for load. If there still has remaining energy, it will be supplied for grid-connection generation, as shown
in Figure2-5.
