6.2.1 Parallel Master-Slave Setting
In the Parallel Application, only one “Master” is needed. The rest of the inverters are “Slave”.
The Master does not need to be set, only the Slave. Note! Two inverters cannot be set as Master.
All Slave inverters are required to be set. If two inverters are set as Master, it could cause
permanent damage to the inverters!
Move the cursor to Parallel Set “Master”, hold the
＂∧＂

save.
6.2.2 Series Master-Slave Setting
In the Series Application, only one “Master” is needed. The rest of the inverters are “Slave”.
The Master does not need to be set, only the Slave. Note! Two inverters cannot be set as Master.
All Slave inverters are required to be set. If two inverters are set as Master, it could cause
permanent damage to the inverters!
Move the cursor to Series Set “Master”, hold the
＂∧＂
choose “Master and Slave”. Set and
save. This option includes: “A-Master”, “A-Slave”, “B-Slave” and “C-Slave”. “A-Master” is the
Master inverter. The “B-Slave” is the first Slave inverter.
In the series application, please note the phase sequence! When in Series Application,
the
Slave “Series Set” option must set to “B-Slave” and “C-Slave”, they cannot be set to the
same Slave.
For clarification, see table on page 23.
After setting the master and slave, ensure that your settings and connections are correct to
prevent any errors or failure caused by incorrect operation. If you receive a configuration error
after you have finished the parallel master and slave settings, turn the power off and check your
connections and settings. Then restart the inverter.
