    Hello everyone

    I ve bought three inverters dc to ac. The input is 24V dc and output 230V ac. Each of them 3kVA. I want to link them together to obtain three phase system 400V. Any idea if i can make that?

    Thank you

    You will need some method to synchronize them together with a 120 degree phase angle between them. If the inverters don't have a sync input (unlikely) then you would need a circuit diagram to determine how that could be done.

    3ph Transformer or 3 separate ones Star or delta the outputs.
    Plus what Mr Crutschow said.

    each phase is 230V with respect to the neutral. I need to take to lines to make 400V. But the problem is time and angle between them
