The picture below shows the data cable between the inverters. It doesn't matter which way round these
go, but their length must not exceed 2 meters.
If you need further help please refer to the Sunsynk website where you will find training videos and
frequently asked questions www.sunsynk.com. From here you can also update the inverter operating
system if required, but generally, if the inverter is working fine we recommend do not upgrade
Some common questions when paralleling inverters:
What is the sequence to install/connect/commission?
First of all, leave the main supplies off. Next, connect all communication cables, set up all LCDs and then,
finally, turn-on the main supplies.
What are the indications that the communication and the system are ok or not?
Parallel errors will be shown as fault F46 on the display.
NOTE
If the communication is not working correctly between inverters then errors will show up on
the display. In this case, please check all settings and data cable.
IMPORTANT
The load outputs can be connected in parallel.
The grid input can also be connected in parallel.
You cannot connect the Aux/Gen port in parallel, because this causes a conflict between
the frequency of the generator and the frequency of the grid.
