How to Remove parallel system
If one inverter wants to exit from this parallel system, please do the steps as
below:
- step1: Disconnect all the network cables on the CAN port.
- step2: Disconnect all power cables (R/S/T/N/PE) connected to X3-Parallel Box
or X3-EPS Parallel Box.
- step3: Enter setting page and click parallel setting, and choose "Free".
Note!
- If a slave inverter is set to "Free" mode but not disconnect the
network cable, this inverter will return to "slave"mode
automatically.
- If a slave inverter is disconnected with other inverter but not
be set to "Free" mode, this inverter will stop working and
maintain "waiting" status.

Main display:
Once inverter enters parallel system, the "today yield" will be replaced by "
Inverter Class", and parallel relevant fault has a higher priority than other
faults and will be showed rstly on main display.

Parallel Control Function
Master inverter has an absolute lead in the parallel system to control all
slave inverter's energy management and dispatch control. Once master
inverter has some error and stop working, all slave inverter will be stop
simultaneously. But master inverter is independent of all slave inverter
to work and will not be affected by slave inverter's fault.
Overall system will be running according to master inverter's setting
parameters, and most setting parameters of slave inverter will be kept
but not be cancelled.
Once slave inverter exit from system and be running as an
independent unit, its all setting will be re-excuted.
The rest of this section covers several important parallel control
functions, and the next page table shows which LCD options are
controlled by master inverter and which can work independently.
Off mode setting:
Off mode can only be set by master inverter ( long press ESC button on LCD ) .
Safety setting:
System safety protection is cancelled by master inverter's safety. slave
inverter protection mechanism will only be triggered by master
inverter's instructions.
Self-use setting:
If system is running as self-use mode, please note the Feedin Power Limit
set of master inverter is for the overall system and the corresponding set
of slave inverter is invalid.
Power Factor setting:
All sets about power factor are all for the overall system and the
corresponding sets of slave inverter are invalid.
Remote control setting:
The remote demand instructions received by master inverter will be
interpreted as the demand instructions to overall system.
