If memory serves me correctly and this is the off grid Generac they are available as a 120 volt and it takes a new breaker and rewiring to get 120 / 240 out of them
I run into this in the past they actually had it wired for 240 into a balancing transformer to feed 120 into the inverter We could've just left it at 120 volt Later, Bob ellison Bob Ellison > On Dec 16, 2014, at 11:33 AM, "Baxter, Gary" <gbax...@sensata.com> wrote: > > Hi Mac, > Jay just had the same issue and it was 120v from the gen instead of 120/240. > The inverter was charging using half the windings causing it to Overtemp. > > Check the 60A breakers on the side of the inverter.
