Peak load Shifting (Load Shifting)
Set the maximum power Pmax (kVA) contracted
with the grid.
When the load consumption is less than the
Pmax, the PV will charge the battery first, and
the grid supplies the load. When the battery is
full, PV will supply the load together with the
grid, but the battery doesn't.
When the load consumption exceeds the Pmax,
the inverter will take power from the battery and
PV to supply power to the load to compensate
for the power that exceeds the Pmax.
*To realize the “Peak load Shifting” function, the load power that exceeded Pmax has to be within the inverter
max output power, otherwise, the inverter will only output the max power which allowed.
