<div>I've got a customer that has an issue with their
~10 yr old SB8000US connected to a quad stack of Sunny
Island system that's off-grid.</div>
<div><br>
</div>
<div>It looks like it's on and off, trying to make power
but seems to think there is a problem on the AC side.
Do you have any advice as to what may be going on?
Anything that I can do that may not require
replacement? Very tough communicating to SMA while on
site and of course, this always happens on Friday
night.</div>
