I would normally want at least a 200A rated DC disconnect, as William discusses above, but the inspector said a 100A knife switch would satisfy him, just as an emergency kill switch. I would love to see the battery manu's have an internal kill switch with a small RSD button that we could locate next to the other required RSD button.
William, there is no lockable feature on the simpliphi/briggs LFP batteries, unfortunately.
