I'm working on designing a system which involves a Solectria inverter. The Max. Continuous Output Current listed on the cut sheet for 480V is 100A. I multiply that by 125% as required by article 690 for OCPD and wire size, and there's my rating, 125A fuse in the AC disconnect, #1 wires.
Then I looked at the installation manual; the manufacturer states that the AC disconnect should be connected to a 150A circuit for this model, and the integral fused disconnect needs 150A fuses. Would it be a violation of 110.3(B) to install 125A OCPD and #1 as I originally calculated, since this is technically not following the manufacturers installation instructions? I will most likely revise our drawings to accommodate this just to be sure, I'm just curious if it would've been a violation.
They also state that 90 degree conductors are required...is this common for inverters?
