I have install which uses Solaredge inverter SE43.2KUS 208V three phase.
From inverter AC side to AC panelboard wire size used is (3)#1/0 + (1)#6 AWG NU + (1)#6GND
From AC panelboard to the AC fused disco the wire size is
(3)#400kcmil +(1)#2/0 AWG NU + (1)#2/0 AWG Gnd
The neutral provided in both cases is same size as EGC.
The AC fused disco is taped off building main service supply side and the same cable that is tapped off feeds the building main service disco which is used for storage.
Questions:
1. Does Solaredge inverter require full size neutral?
2. How does one size neutral for solar edge inverter?
3. Would it be acceptable to provide just neutral for instrumentation, controls ? Would not Solar feeds the building loads would that not create huge unbalanced load? Anyone know or have any experience
