<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>

<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>
