Hi
Hi All,
So I went back today and updated all the programming. There was actually
lots of sun too (a rare event in upstate NY this time of year)!
The inverters have not yet had any issues with powering the backed up loads
so far. But there have been issues with selling back to the grid. One
Forgot to say that if the inverters ARE grid tied, then they will NOT
drift around in phase and will
be synchronized and therefore will stay in sync and be passing through
from grid to output.

You can test to see if both inverters are staying in sync by just
watching the voltage between L1 and L2 of the
outputs for a while. If they do not deviate much from 240VAC over
several minutes, then they are probably
sync'd OK... You can also help verify this by unplugging the sync
Well l would start simple and get a sync cable and make sure that they are
al least staying g in correct phasing, then look closely at the
programming, look at the grid voltages and settings, take it out of IEEE
for test purposes only, you might find out you have a board that's out of
calibration

Dave,
Sorry, misspeak on my part. It is DC negatives and grounds that are tied
together. No neutrals in the DC box.
Cheers,

Why would neutral be in the DC conduit box? This just wrong but I doubt
this is the problem.
Since this never worked properly or has not in 13
years, I would suggest replacement with modern equipment. SW from xantrex
has been out of support for around 15 years and always was a headache grid
Hi All,
I am someone's last ditch effort to get their system working which has been
non-functional since a few months after installation, 13 years ago...
After getting some new batteries in there, I can at least fire it up. It is
a grid tie with battery backup situation with two Xantrex SW4048
