Grid and new Generator have different Phase Sequence, how to correct?

My 3 Phase Grid sequence is (According to the grid meter on the color controller) L1-L3-L2

I just connected my new generator and with the....


Multiplus's switched to "on" Inverter lights on constant. No Battery Charging.

Multiplus's switched to "charger only" main lights flash on line 1,2, main and float lights flash on line 3, No Battery Charging.


I then checked my 3 phase Generator sequence and (According to the grid meter on the color controller) it's L1-L2-L3


What is the best way to fix this issue, I guess the system is set up for L1-L3-L2 as it all works fine when the grid is connected.

I did wonder if I could just switch L2 and L3 on the Genset plug wiring but thought I would ask first.

I am answering my own question in case someone has the same issue. I switched L2 and L3 over on Genset, now Genset and Grid have same phase sequence. Everything now works OK.

I have the same problem. So you did only switch the L2 and L3 at the IN and OUT Port from the EM24, or?

As he says above, he switched L2 and L3 on the generator.

Switch L2 & L3 only at the EM24 input.

I have a 3 phase Multiplus System. Think, if I only change the EM24 Input Port, then a phase rotation error would appear in the MP System, since you set each Multiplus to a specific phase in the VE Configurator
