I want best of both worlds, solar power but grid power if needed. I wired this up myself, and need to know if it is safe. Please assume all wire diameter, fuses, circuit breakers are all up to, or above spec. From what I can gather, 2 Neutral bonds are acceptable as long as they are separate utilities. My solar system I believe counts as a separate utility since it does not use the grid neutral. I hope someone can verify this. Thanks in advance!SolarWiring.jpg
