Hello All,
We have a split-phase (NA type grid) but at 50 hZ.
We are having trouble in finding smaller (3 kW to 5 kW) hybrid inverters that do split-phase output.
As such, we have been investigating autotransformers and using them with EU spec (230V - 240V @ 50 hZ). The EU units in the size range are easy to find.
However we have been having less luck finding autotransformers. We have seen the Growatt ATS-US unit, Solaredge 5000, Solax and Victron (not remembering all the model numbers).
But they are all very expensive. Growatt - 250 USD, Solaredge - 400 USD, Victron 600 USD+.
Are there any other autotransformer vendors/manufacturers (5000 W range) that you would recommend (read as cheaper, but work)?
Or should I be thinking about a plain step-down transformer (240V - 120V) and ignoring all all of my 240 loads when in "backup mode".
Let me know your thoughts.
Cheers,
Kirk
