If you do go with a transformer I'll second Dongan. They know solar and will build to match your inverter output so no material is wasted.
CPS just released a 25kW 208V inverter...but it might be more cost effective to use a 480V inverter and transformer depending on layout, conduit length, equipment location, etc. Best, Garrison Riegel On Fri, Sep 18, 2020 at 5:31 PM August Goers <aug...@luminalt.com> wrote: > We have a similar size system in the works and a designer recommended > Dongan transformers: https://dongan.com/product/ > > I have not sourced them or worked with them yet, but they definitely have > models that will work spec-wise with the CORE1 inverters. > > August > > > On Fri, Sep 18, 2020 at 3:10 PM Jerry Shafer <jerrysgarag...@gmail.com> > wrote: > >> Wrenches >> I use the SMACore and step-down transformer >> Jerry >> >> On Fri, Sep 18, 2020, 1:04 PM Chris Mason <cometenergysyst...@gmail.com> >> wrote: >> >>> I'm bidding a commercial rooftop of about 200KW using string inverters. >>> The voltage is 208V 3Ph 60Hz, and I can't find an inverter over 15KW.
