<font size=2 face="sans-serif">Hi:</font>
<br>
<br><font size=2 face="sans-serif">From your description of the problem
and the video, I suspect the problem is due to:</font>
<br>
<br><font size=2 face="sans-serif">1. The inverter is exporting very near
full power.</font>
<br><font size=2 face="sans-serif">2. The grid voltage rises which at the
same AC current results in larger export power flow above the inverters
limit.</font>
<br><font size=2 face="sans-serif">3. The inverter stops exporting due
to reaching its power limit</font>
<br><font size=2 face="sans-serif">4. The inverter again starts exporting.....</font>
<br><font size=2 face="sans-serif">5. Reaches power limit and stops.</font>
<br><font size=2 face="sans-serif">6.etc.......</font>
<br>
<br><font size=2 face="sans-serif">I.E. since the inverter is working close
to its power limit on a grid with fluctuating voltage, it goes in
and out of max power limit. </font>
<br>
<br><font size=2 face="sans-serif">One way to test if this is the cause
is to reduce the Sell Amps so that you are not operating at the power limit
of the inverter.</font>

<br><tt><font size=2>We installed a XW 6048 that has wide power output
fluctuations over <br>
several seconds. Lights flicker, and the inverter squeals. It happens <br>
multiple times in a minute The inverter was replaced to no avail.
I <br>
suspect the local utility's poor line maintenance. When the inverter <br>
begins to drop off line, the voltage sags from 123 to 117. This is
<br>
still within normal parameters, so I don't understand why the inverter
<br>
would begin to power down. Here is a youtube video of it if anyone
has <br>
ever seen this before. Schneider has assisted us several times, but <br>
cannot find any reason for this happening as a result of their technology.<br>
