Fronius primo US version on 230V offgrid system

fatfash Registered Users Posts: 2
I recently bought a fronius primo 6kw  single phase off ebay to replace my old SMA 4000tl in my AC/SC coupled off grid system. After installation which is a direct swap, the fronius did not power on, no display nothing. From the manual the unit should be able to work with a system of 230V/50Hz but it won't come up, is there anything am missing that is not making the unit to power up or is the unit faulty? please I need help on this. I have reinstalled the SMA sunny boy and works perfect, any help will do..

Thank you

    Sounds like someone unloaded their dud inverter on ebay and you bought it.    Does fronius  need any bus control module or programming module that you didn't purchase ?

    No, not any that I know of. I expected the unit to power on at least
