For example, when the PV system generates 8 kW of power, the 5KTL inverter
feeds the maximum output power of 5.5 kW to the grid and charges the ESS at
2.5 kW. When the solar irradiance decreases, resulting in the PV system generating
only 3 kW of power, the ESS discharges power at 2.5 kW to ensure that the
inverter continues to feed the maximum output power of 5.5 kW to the grid.

This mode maximizes the PV energy fed to the grid. When the generated PV
energy in the daytime is greater than the maximum output capability of the
inverter, the ESS is charged to store energy. When the PV energy is less than
the maximum output capability of the inverter, the ESS discharges to
maximize the energy fed from the inverter to the grid.
Set the working mode to Fully fed to grid. For details, see
Parameters.

Meaning
High voltage exists after
the ESS is powered on.
Residual voltage still
exists after the ESS is
powered off. It takes 5
minutes for the ESS to
discharge to the safe
voltage.
