Step3: On the inverter with meter connected, usually the Master, select "Parallel
setting" in the setting, and change the status to "Master".

How to exit from parallel system
If you need to exit parallel mode on any of the inverters, please follow the steps:
-Firstly, disconnect all the CAN cables on this inverter.
-Then change the parallel setting to "Free". This inverter then can work standalone.
Note!
- If a slaver inverter is set to “Free” mode but not disconnect the network
cable, this inverter will return to “Slaver”mode automatically.
- If a slaver 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 “ Inveter
Class”, and parallel related faults have higher priority to be shown on the LCD
display than the other faults.

Parallel Control Function
Master inverter in the parallel system has absolute control of all slaver inverters'
energy management and distribution control. Once the master inverter comes
with an error and stop working, all the slavers will stop simultaneously. But the
master can work independently from all slavers thus it will not be affected by any
slaver's error.
The whole system will be running according to the master's settings,
and most settings on each slaver will be kept but not be excuted. Only when the
slaver inverter is set free from the system, running as an independent unit, all its
settings can 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 ( press and hold the forth key) .
Safety setting:
System safety protection will be the same as set on the master inverter. Slaver
inverter protection mechanism will only be triggered by the master inverter.
Self-use setting:
If system is running as self-use mode, please note the FeedinPowerLimit set of
master inverter is for the overall system and the corresponding set of slaver inverter
is invalid.
Force on time setting:
If system is running as force on time mode, please note all sets about force on time
are all for the overall system and the corresponding sets of slaver inverter are invalid.
Power Factor setting:
Power factor will stay the same as set on the Master inverter, while settings on the
slavers will be invalid.
Remote control setting:
The remote demand instructions received by master inverter will be interpreted as
the demand instructions to overall system.
