[RE-wrenches] Sawtoothing on the SW6048

[Mark.Edmunds at ca.schneider-electric.com]

Hi Drake, Peter,

I think the XW issue under discussion is one I am familiar with, and was a 
minor instability that under certain conditions was causing fluctuation in 
sell mode power flowing back to the grid. This was addressed quite a while 
ago, as part of our ongoing product improvement efforts. We always strive 
to follow through on any issue that arise with our products, and in this 
case due to not being able to replicate the issue in our lab we sent an 
Engineer to Peter's site so we could get to the root cause of what was 
going on.

If there is some item of concern please do contact our tech support folks, 
who will do their best to help.

The XW series is a popular product family, and we will always respond to 
any issues that may arise to ensure as best we can that the device 
performance meets the needs of the users.

Best Regards,

 Mark

when my grid
voltage went a little high (124-125 v)


Hmm.  That voltage is pretty common.  Why would the inverter need to be 
set higher than 132 V when the grid is still seven volts lower than that. 
If that truly did fix the problem, the inverter is problematic, IMHO. 

Many thanks to the members of the list who have given me the "heads up" on 
the recent Xantrex products.  Even though they have the very desirable AC 
IN 1 and AC IN 2,  I've stayed safely away.
