I posted this as a reply to an old previous post but since there are not email notifications I thought no one would see it so please excuse me if thats not the case.
Update with a few observations and questions from a electrical rookie. I got my system set up 240/120, both gen sets, the ST5 and Northern 2.9 KW. We had a three day power outage and everything worked fine except I spent allot of time balancing the loads. My UPSs didn't work right and the lights flickered when reefers cycled etc... Not a big deal, I was warned about balancing loads. I didn't need 240 for my pump so all this hassle could be eliminated if I just go back to 120. (I have a plan for 240 and the deep well pump but we'll forget that for now) So, no problem rewiring the ST5 head, but since my northern 2.9 head is (3600RPM) 240/120 wouldn't it be true that if I just plugged into one gen head 120 outlet to feed the system I would only be able to use half the KWs and the gen head would be drastically out of balance? hence my question about being able to rewire it for 120 only or maybe it doesn't matter? I do have an electrician/friend checking my work but you folks have the generator part down and have been a great help on that end, thank you.
