2. System Working Mode
a) Selection of working mode
① Zero Export To CT: In this mode, the PV and battery will be preferentially used to
supply power to the loads, and the grid will be used to supply power to the loads
only when the battery SOC (voltage) reaches its reserved capacity threshold. The
battery energy is used to power the loads, including the Critical Load and Smart
Load on the AC outputs and Normal Load on the AC input. The battery energy is
not allowed to be fed back into the grid. The excess PV energy can be fed back into
the grid, and the selling (export) power is available for selection.
② Zero Export To Load: In this mode, the PV and battery will be prioritized to power
the Critical Load until the battery SOC (voltage) reaches its reserved capacity
threshold, at which point the grid will assist the PV in supplying power to the Critical
Load on the AC output. Normal loads on the AC input will be powered by the grid
first. The battery energy is used to power the Critical Load and Smart Load on the
AC outputs, and it is not allowed to be fed back to the AC input port, including the
grid and generator. The excess PV energy can be fed back to the grid, and the
selling (export) power is available for selection.
③ Selling First: In this mode, the PV will power the loads first before exported to the
grid, and the battery will assist PV in powering the loads and its energy will be
exported to the grid until the battery SOC (voltage) reaches its reserved capacity
threshold, at which point only the PV will supply power to the loads and export
energy to the grid. When the PV is insufficient, the selling (export) power will be
decreased even to a degree that the grid will provide power to the loads together
with the PV. In this mode, the battery energy is allowed to be fed back to the grid.
b) AC in Charge, can be set as enabled or disabled.
c) Feedback to Grid, can be set as enabled or disabled.
d) Maximum Selling Power.
