<DIV><SPAN class=265443712-04032010><FONT color=#0000ff size=2 face=Arial>I have
never been able to get my generators to connect w/ a grid tie inverter.
The Kohler 20kW Isochronous generator electronic AVR doesn't nor does the
smaller Onan, Honda or even I had a customer w/ 125kW & the SMA
wouldn't latch on despite the quality of power tiring to connect w/o a
load.</FONT></SPAN></DIV>
<DIV><SPAN class=265443712-04032010><FONT color=#0000ff size=2 face=Arial>I too
was told by SMA to connect to the line side of the ATS, but that doesn't mean
that I haven't seen connection to the load side & have seen no ill
effects from this type of connection, just inverter not latching
on.</FONT></SPAN></DIV>

RE-wrenches<BR><B>Subject:</B> Re: [RE-wrenches] Generators and Grid-tie
Systems<BR><BR></FONT></DIV>The issue of what will or will not hurt an
inverter, when connected to a generator, does not seem to be resolved.
The fail safe method, of course, is to connect to the line side of the
transfer switch. Other than that, there are varied views.<BR><BR>There
are systems in operation that intentionally AC couple generators to on grid
inverters. A post on the List had linked to an article about such a
system, but so far I can't find the information. <BR><BR>Has anyone else had
problems with isolation relays? This was a recommended method that
didn't work for me. <BR><BR><BR><X-SIGSEP>
