Thank you, I will see if that is the solution and get back to either
way. Chris

Hi:
From your description of the problem and the video, I suspect the
problem is due to:
1. The inverter is exporting very near full power.
2. The grid voltage rises which at the same AC current results in
larger export power flow above the inverters limit.
3. The inverter stops exporting due to reaching its power limit
4. The inverter again starts exporting.....
5. Reaches power limit and stops.
6.etc.......
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.
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.

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