Counter-current
protection mode
After connection with the grid, PV does not supply the power to the grid
in all operating modes;
Grid-
Tied
mode
Battery-
first mode
(1) PV gives priority to supply the power for the backup load, followed
by charging the battery, and supplies excess energy to the domestic
loads and the grid;
(2) If the power from the PV is less than the power of the backup load,
the battery supplies the power for the backup load and the PV does
not supply the power to the grid.
(3) The battery is not charged by the grid.
Domestic
load-first
mode
(1) PV gives priority to supply the power for the backup load and the
domestic load, followed by charging the battery, and supplies
excess energy to the domestic loads and the grid;
(2) If the power from the PV is less than the power of the backup load
and the domestic load, the battery supplies the power for the
backup load and the domestic load, and the PV does not supply the
power to the grid.
(3) The battery is not charged by the grid.
Grid-first
mode
(1) PV gives priority to supply the power for the backup load, followed
by supplying the power for the domestic load and the grid , and
charge the batter by excess energy ;
(2) If the power from the PV is less than the power of the backup load,
the battery supplies the power for the backup load and the PV does
not supply the power to the grid.
(3) The battery is not charged by the grid.
Full power
feed mode
(1) PV gives priority to supply the power for the backup load, followed
by supplying the power for the domestic load and the grid, and
charge the batter by excess energy ;
(2) If the power from the PV is less than the maximum output power of
the inverter, the battery supplies the power to make up the
difference, so that the inverter outputs maximum power.
(3) The battery is not charged by the grid.
