I'm designing a PV system using 39 panels and 39 mirco inverters that will be divided into 3 branch circuits. I'm being told I will need to run three conduit runs from the roof junction box to the combiner box in the garage. One conduit for each circuit.
After reading the NEC 690.4(B)1-4 and if I'm reading it correctly it can be in 1 larger conduit as long as all conductors are identified.
Does anyone know the ruling on this? It doesn't make sense having to make 3 separate pipe runs.
