X3-Retro Fit Series Inverter provides the parallel connection function which should
make ten inverters maximumly connected in one system when the grid is on.
In this system, one inverter will be set as the "Master inverter" which will control
every other inverter’s energy management and dispatch control. Only one meter
needs to be connected in this system and communicate with the "Master inverter" ,
and all the other "slaver inverters" communicate with “Master inverter ” by CAN
communication-parallel connection.
Please note the parallel connection function can only be used when the
grid is on .The off-grid parallel connection function is being developed.
Note!
System Diagram
Work Modes in parallel system
There are three work modes in parallel system, and your acknowledge of different
inverter’s work modes will help you understand parallel system better, therefore
please read it carefully before operating.
Free mode
Master mode
Slaver mode
Only if no one inverter is set as a “Master”, all inverters are in free
mode in the system.
When one inverter is set as a “Master”, this inverter enters master mode.
Master mode can be changed to free mode or slaver mode by LCD
setting.
Once one inverter is set as a “Master”, all other inverters will enter
slaver mode automatically. Slaver mode can not be changed from
other modes by LCD setting.

Wiring Operation and LCD Setting
Note: Before operation, please ensure that all the inverters’ software
version must be the same, otherwise the parallel function will not work.
Step1: Connect all inverters’ communication together by connecting network cables
between CAN ports.
- Use standard CAT7 network cables for CAN-CAN connection and CAT5 cable for
Master-Meter connection.
- Insert one side of CAT7 cable into the rst inverter’s CAN2 port and the other side into
the next inverter’s CAN1 port.
- Insert one end of CAT5 cable into 485A/B on SolaX meter, and the other end into
the meter terminal inside the Master inverter.

Step2: Set the DIP switch (No need to set on all the inverters) .
- Find the inverter with meter cable plugged.
- Remove the bottom-front cover from this inveter, and nd the DIP switch on
the right of the CAN2 port on the control board.
- Push the white DIP switch to “ON” position (from down to up) by a suitable
tweezer. (Note: No need to set it for all, but only for the Master inverter and one
of the Slavers.)
