I have a customer that has a problem with a new generator. He has two
VFX3648 inverters in Outback stacking. He acquired a new generator, a
Kohler 12RES, a reputable make and model. Below is a description of the
problem:<br>
<br>
<i><span style='font-size:10.0pt;font-family:"Arial","sans-serif"'>The 12RES
seems to be operating OK except for one problem. At the end of a charging
cycle, when the gen automatically shuts down and load goes back to the
inverters, all lights, TVs, etc., flash, one TV shuts off, and a GFI
trips. This has happened every time. It did not happen with the
15RES or the smaller back-up gen (which was disconnected manually). With
the 15RES the same GFI would occasionally trip while the unit was charging and
handling house load, but never at the auto shutdown point. I replaced the
GFI, but it still trips. There are three GFIs in the house, but only
one--always the same--trips.<br>
<br>
<br>
</span></i>I suggested he adjust the AC2/Gen transfer delay to a lower
number. He reduced it to minimum and this did not resolve the
problem. I also had him verify that the AC source is selected as
generator, which it is.<br>
<br>
Do you have any suggestions?<br>
<br>
Thanks in advance,<br>
<br>
