My system consists of:
3 Multigrid 48/3000/35
1 Color Control GX
6 Pylontech US2000 Plus batteries
The Multigrid are installed for three-phase system out of the AC-OUT port.
I have followed the instructions from this documentation until including step 3:
I want to continue with the configuration (step 4), but all three Multigrid did not start (i.e. none of the LEDs blink) after I switched them on. Note that a grid voltage of 230V can be measured at the AC-IN ports of the Multigrid.
What is causing this problem and how could it be solved? I would appreciate any help!
Thank you very much.
