Hello Wrenches,<br><br>
Attached is an article from Home Power that came in my email. It says
module degradation is increased by PID (Potential Induced Degradation) by
the use of transformerless inverters. It says power degradation can
occur over days or weeks and cause a 10% to 60% loss of efficiency.
<br><br>
I called Power One and SMA and their tech support people have not had any
reports of problems. Is this something we need to be concerned
about?<br><br>
<br>
Thanks,<br><br>
<br>
