Description
▪
Charge preference: When the PV energy is
greater than the loads, excess PV energy is used
to charge the ESS. After the maximum charge
power is reached or the batteries are fully
charged, the excess PV energy is fed to the grid.
▪
Fed to grid: When the generated PV energy is
greater than the loads, the excess PV energy is
preferentially fed to the grid. When the
maximum output power of the inverter/Smart
PCS is reached, the excess energy is used to
charge the batteries. This setting is applicable to
the scenario where the feed-in tariff (FIT) is
higher than the electricity price. The batteries are
used only for backup power.
Set the maximum power for charging the batteries
from the power grid.
Control the maximum target grid power when the
grid-connection point has zero power.
Allowed fluctuation of the target grid power for the
grid-connection point
▪
Enable: Automatic SOC calibration is enabled. If
the total charge and discharge energy reaches
the threshold or the calibration function has not
been triggered for 30 days, the SOC automatic
calibration is performed. The SOC automatic
calibration is performed in battery racks. During
calibration, the cut-off SOC settings will be
ineffective.
▪
Disable: Automatic SOC calibration is disabled.
Set the Charge/Discharge time. A maximum of 14
time segments can be set. You can set a cycle by
week by clicking the buttons corresponding to Mon.
through Sun. in the Repeat box. The buttons are
blue by default, indicating selected. After you click
it, the button turns gray.
