I use a Fluke 36 amp clamp and i have to flip the meter to get the
current flow direction right otherwise I always get a difference like that.

Hi Corey,
Are you sure the meter was zeroed? If the meter was reading 0.5A at rest,
then that would happen.

Try rotating the meter so the current flows the other way and see if the
effect is reversed. You probably have to zero the meter.
the current should be the same in every part of the circuit.

Wrenches,
I recently noticed something that seems to defy one of my basic
understandings of electrical circuit theory:
Single string input at inverter. Clear skies, full sunlight. With inverter
turned on my clamp meter reads (for example) 5A on positive conductor and
4A on negative conductor.

Greetings Wrenches,
I looked at the article a bit more closely and a crack emerged. The
article mentions two Spanish projects that were tested and the modules
had a 34% "defect rate." I looked at the study (linked in the article)
and what they were talking about was thermographic defects - hot
