2.3.3 Mode Description
PCS operation mode includes the grid mode and off-grid mode.
Grid mode:
In grid mode, PCS can charge and discharge.

Charge: constant current charge, constant voltage charge, constant DC
power charge, constant AC power charge, etc.

Discharge: constant current discharge, limited voltage discharge, constant
DC power discharge, constant AC power discharge, etc.
Off-grid Mode:
This mode can be set up through iSolarCloud App or EMS. In off-grid mode,
PCS can supply AC power with constant frequency to loads.
