SolaX Power X3-Hybrid-10.0-D-E - On Grid Parallel Connection

X3-Hybrid 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 other slaverinverter 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 develped.
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 this function can not be use.
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
CAN-Meter connection.
- Insert one side of CAT7 cable into the rst inverter’s CAN port and the other side
into the next inverter’s CAN port.
- Insert one side of CAT5 cable into the Meter port of meter, and the other side into
the CAN 1 port the rst inverter or the CAN 2 port of the last inverter.
-( Note: PV and battery should both be connected to the inverter with meter cable plugged.)

Step2: Set the DIP switch (No need to set all inverter’s DIP swtich) .
- Find the inverter with meter cable plugged.
- Remove the top-down 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
tweezers.
(Note:Please pay attention to the position of the DIP switch, which is very small)
