B. On-Grid Parallel Connection
AX 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 slaver inverter 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.
Parallel 1/2 are the ports used in parallel. The system diagram is as follows:
