Or, am I confused on what electrical engineers actually do?
That *IS* possible, since i'm not one.


For a given insolation, a PV panel looks more like a current
source than a voltage source.

Depending on how your PV array is wired, it can be generating
1000+ volts,


Not if it's a residential solar system, which is what we are
talking about here and it complies with the NEC. NEC limits the
maximum voltage to 600V. And you claim to be installing these?


I'll clarify this for you, since you seem to be ignoring things, and,
I suspect you're doing so intentionally at this point. The PV array
consists of TWO strings. When tested together, in series, they
generate a little over 1000+ volts, DC, yes, they most certainly do.
The voltage drops by half and doubles the amperage inside the
combiner box on the lines which feed the inverter (parallel)

So, it's well within NEC specifications. The other line that comes
out of the combiner box keeps them in series to feed my 'modbox'.
It's not concerned with high amperage output, it needs the higher
voltage, instead. It all passed electrical inspection too. We didn't
pull any 'hide the ****' until the inspector leaves and continue
wiring.


I am curious, which make and model of panel was used in this array?
How many panels?
