I have three strings in parallel. String 1 has 20 modules, string 2 has 30 modules and string 3 has 40 modules. String 1 circuit goes straight to inverter. String 2 circuit goes straight to the inverter and so does string 3 i.e there is NO combiner. Each module voc is 9V.
Inverter input voltage rated for 600V dc. String 1 voc is 180V, string 2 voc 270V, steing 3 voc is 360V. Which string voltage would be used to determine the final voltage to compare against inverter rated input voltage based on code?
