The outputs are pretty close. That’s what is throwing me off. In most trouble shooting adventures, the problem is fairly obvious. This one, not so much.

Is the output from each string of 11 the same? Have you tried ruining 1 string at a time?

The system is as follows: 44 – Siemens SP-150 1 – SMA SB6000US-12 (XFMR unit) Since install, they have not produced half of what they should be. I have tested the diodes and they seem to be good, there were a couple that tested questionable, so they were replaced. VOC is good, but it seems that under load the system goes to garbage. I am at a loss of what/how to test anything else that may determine cause. Would a PV Analyzer help? Would there happen to be anyone in the Sacramento area with one who could come to the site? Obviously the customer will pay for their time. Thanks in advanced. SMA America, LLC Steve Jefferson Service Line Supervisor 3925 Atherton Ave Rocklin, CA 95765 - 3714 U.S.A.
