I am putting together my first solar system and need some advice. The diagram attached shows a blue line down the middle - all items to the left have already been purchased, and to the right are items I am not 100% sure of, in particular, the Square-D 200AMP Disconnect (D324NRB). I read at http://www.thesolarplanner.com/steps_page8.html the following:
"For the AC disconnect itself, you would choose a 30-amp model, 2-pole product. If your inverter is transformerless, and you decide to buy a fusible AC disconnect, you'll need to get a 3-pole model in order fuse the neutral conductor in the circuit, since it won't be grounded."
The two inverters for my system are SolarEdqe "Transform-less SolarEdge SE11400A-US 11.52kW, 240V, 60Hz Continuous Output Current 48A". Being that they are transformless, and the advice above, I think I should use 3 fuses for Ll, L2 AND Neutral... Is that correct? Any advice on this or anything else in my drawing would be greatly appreciated.
