When installing a disconnect on the A/C side of an inverter -- usually adjacent to the utility meter box -- which side is considered the "line" and which is the "load" ??
I figure that the "line" side should be the premises wiring panel, and the "load" should be the inverter, even though the current will be flowing in the opposite direction.
Since the inverter will disconnect itself if it senses the loss of utility power, putting its output on the load side of the disconnect won't end up with energized blades exposed with the disconnect in the "off" position.
Do you have a preference, or a valid reason why it should be the other way around?
