Hi all,
Just wondered if anyone could offer advice on filling in the PV test array form?
There is a section on protective device. I assumed it was the MCB but there is a box for DC rating and kA capacity. This leads me to believe it refers to the DC isolator?? but thats an isolator not a protective device? or does it refer to the inverter?? im sure im over thinking this... would really appreciate some help!!
 
If there is no protective device then the answer is... n/a

on commercial systems usually with 3 string combining or more then there would (should) be DC string fuses, but that doesn't apply to most systems.
