Description
▪
Charge: 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 ESS is 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 ESS is used
only for backup power.
Set the maximum power of the grid during battery
charging.
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
