5) Machine factory default for single machine mode, if you use parallel or three-phase function, you need to set
the”Parallel mode “ item parameters through the screen. The setting method is: power on one machine at a
time, the rest of the machine off, and then set the ”Parallel mode “ item parameters according to the site
system operation mode. After this machine is set successfully, turn off the machine switch and wait for the
machine to be powered down, then set the rest of the machines in turn until all machines are set, and then all
machines are powered up again at the same time and enter the working state.
The”Parallel mode “ setting item：
When in single-phase parallel connection : setting”Parallel mode “should be set as “Single-phase parallel”.
When in three-phase parallel connection, setting ”Parallel mode “ should be set as follows: all machines in
phase 1 must be set as “3PAL1”, all machines in phase 2 must be set as “3PBL2”, all machines in phase 3
must be set as “3PCL3”. At present, the voltage phase difference between P1-P2, P1-P3 and P2-P3 is 120
degrees.
a. When the output voltage set in the setting output voltage is 230Vac (S model), the line voltage between the
live wire L1 in phase 1 and the live wire L2 in phase 2 is 230*1.732 = 398Vac, and similarly the line voltage
between L1-L3, L2-L3 is 398Vac; the single phase voltage between L1-N, L2-N, L3-N is 230Vac.
6) After the system runs, the output voltage is measured correctly, and then the load setting is connected.
