In this mode, inverter output is physically separated from grid, therefore, no
power can be injected to grid.
On-grid mode- Net Metering
Inverter is physically connected to grid (mains) directly. The power to loads is
managed to be:
1.
From SP VITALITY-S only: In case the power from solar is enough, SP
VITALITY-S converts PV power to loads directly. In addition, surplus
PV power (in addition to charge battery and loads) is fed to grid so
as to reduce the net power demand in certain period
2.
From both SP VITALITY-S and grid: While the power from PV is not
enough, SP VITALITY-S and grid share the power
