I purchase this new years ago before HSG became
really popular and I was single. LOL
I ran it with a Wisconsin V4. Worked great.
Ran my whole house using two of the legs
(220 single phase).
This is a 3 phase generator head.
Nice thing about this is you can reconnect it
to get various 3 phase voltages out of it.
I have original manuals.
It has phase, voltage, stabilization adjustments.
It's been inside it whole life.
Or best offer.
