Use Modbus card to synchronize the parameters:
Each inverter should have one Modbus card. Make sure all of the Modbus cards are
connected to each other and one of the Modbus cards is connected to the computer
by RS-485/RS232 converter.

Setting >> Parallel output. Two options: Enable or Disable.

There is a “Sync” button in each parameter setting. When “Sync” is clicked and
“Apply” is pressed, this new setting will be applied to all inverters. If not, this setting
is only applied to current inverter you choose.
Note: Without centralized monitoring system, “Sync” function is not effective. Then,
you have to set up the inverter one by one through serial communication
port.
