Grid tied solar array has voltage but no current

[lindq530]

Problem solved. It was a failed inverter. Argh.

Long story:
After measuring voltages, wire continuity, and currents (the easy stuff), everything indicated it was a failed inverter. Luckily (so I thought) I had an identical model replacement inverter. I swapped inverters and the problem didn't go away. Based on that I concluded (incorrectly) that the inverter wasn't the issue. That led me to further about 10 hours of work checking of wiring, individual panels, etc.

After I was exhausted checking everything else and not finding any issues, I decided to purchase a replacement inverter. Installed the new inverter and voila - the system worked great.

I hope my experience can be helpful for someone. Thank you for everyone's responses.

I presume there are diodes, but the junction boxes are potted so I don't have access to them (if they do indeed exist).

I did not check the Isc of the string. I will do that tomorrow morning and report what I find.

Please don't make or break the Isc connection while the sun is out.
