<DIV><FONT color=#008000 size=4 face=Arial>I am having similar issues, but with
an older system with an 8.5RMY Kohler. However we replaced a control board on it
several months ago. As this system goes back to Y2K, starting with a Trace Power
Panel, and converting to the XW when they were first available, it had always
connected to the Gen. with no issues. But recently, we've been getting fault
codes when it exercised, which we thought were related to starting battery
issues. Then, after lighting storms, the XW no longer accepted AC1, grid power,
so we replaced the control board, which fixed AC1 . But in verifying system
operation, we noticed that AC2 - Gen.- would not actually transfer and charge if
started manually at the system control panel thru the AGS, nor would it exercise
properly, as the generator shuts off after a minute or two, never having
actually connected to the XW. Voltage at AC2 is 120 each leg. We have talked
with every tech support at Schneider------------</FONT></DIV>

<DIV><FONT color=#008000 size=4 face=Arial>Yesterday we did the firmware
upgrade, which means for this older system, that the AGS senses the 'generator
on' with out a separate sense wire, like was originally needed. But we are
getting the same failure to connect and charge. We do get a sound like it is
trying to connect, but only momentarily. We still have the same generator
shutdown after a minute or two. The fault code on the SCP, says the generator
turned off<STRONG> at the
generator .</STRONG></FONT></DIV>
<DIV><FONT color=#008000 size=4 face=Arial>Now, since we just went thru the east
coast hurricane, grid was down for this customer for 7 days. so when the
generator is started <STRONG>at the generator, manual start
switch </STRONG>the XW accepts the AC2 power perfectly, starting to charge
within seconds, and going thru the regular bulk charge cycles properly I
believe. So noise from the Kohler, at least this one, seems
unlikely.</FONT></DIV>

discussing this with Kohler tech support.</FONT></DIV>

Gen vs XW</DIV>
<DIV><BR></DIV>Friends:<BR><BR>Working yesterday on a newer XW system with a
new Kohler RES15 generator. This is the first time I have tested the
inverter with this generator. The inverter would not maintain a transfer
to the generator. After about an hour on the phone with tech support,
the tech searched previous calls and announced that there is a known
incompatibility between the Kohler RES15 and a certain version of the XW
firmware. I was advised to upgrade the firmware.<BR><BR>I wonder how
this can be. Voltage and frequency even in the moment the inverter did
try to connect are well within specifications. After some thought, all I can
guess is that there might be some noise on the AC signal that the inverter
might reject.<BR><BR>Has anyone else experienced this? Any insight to be
offered?<BR><BR>Thanks in advance.<BR><BR>William Miller<BR><BR><X-SIGSEP>
