Quattro 240VAC 60HZ to 120VAC 60HZ (L1-L2 to L1+N / L2+N)

Hello everyone,


System Description;

6x Quattro 240VAC 60Hz / 8000VA

20x LiFePO4 25.6V 200A


I will set the Quattros in the system to 240VAC 60Hz (L1-L2)


The problem is, how can I provide L1+N (120VAC) or L2+N (120VAC) from this system.

So I will get L1+L2 (240VAC 60Hz) from the Quattro output. But my requirement is L1-L2+N

Is this possible without an autotransformer? The reason I don't want to use an autotransformer;

Input 1 - Shore connection

Input 2 - Generator connection

As far as I know, the autotransformer creates a neutral connection point thanks to the earth relay.

I look forward to your advice and comments.

Do you mean that you have 6 120V Quattros in 2 parallel-split phase strings of 3 stacked for 120/240V output, or do you mean that you have 6 stacked 230V/50Hz Quattros that you will program to single-phase 240V/60Hz output? Please post a schematic of your existing setup so that we can best assist!

Hello, thank you very much for your reply.


I plan to use 24/8000/200-100/100 230VAC 50Hz Quattro, but I need L1-L2+N

Why do you not buy then the 120V version?

If you need split-phase 120/240 out from a 230v unit that's been programmed for 240v single-phase output, then the Autotransformer is your easiest solution. Have a look at this schematic (or have your electrician /installer look at it)
