9. CT Calibration
To calibrate the direction and phase of the CT, the battery should be charged or
discharged when using this function.
A. The input must be connected to the battery, and the output
must be connected to the grid for normal calibration, otherwise the
calibration will fail.
B. When carrying unbalanced load, the calibration will fail. It is
recommended to turn off the load when carrying out CT
calibration.

Function: the inverter can be controlled by the inverter switch machine through this
menu, so that the inverter can be shut down, the inverter can stop working and turn
into standby state, and the inverter can be to normal output working state. This
function can effectively and safely control the inverter switch machine and
facilitate installation and maintenance.
11. Unbalanced Support
The default is prohibited.
Application scenarios: When the system is connected with three-phase unbalanced
load or single-phase load, the inverter outputs power to the load, and the remaining
two-phase or three-phase unbalanced output is incorporated into the power grid.
This reduces the quality of the grid, and photovoltaic power generation is not used
most efficiently.
The customer can set the enable to turn on the three-phase unbalance support, and
the inverter can detect and identify the three-phase current unbalance at the
common connection points of the grid in the system through the meter or CT. The
