[RE-wrenches] Battery RSD

[jay]

I’ll let the code experts chime in, but I would ask for the code reference they are referring to.

The only one I can think of has to do with if the batteries are on the other side of a wall.

 Thats as clean an install as they come

He mentioned some type of knife switch within 5 feet of the equipment. I cannot find any reference to this requirement anywhere but he insists it is required. These batteries happen to be simplify or brakes and Stratton batteries and each battery has its own 80 amp breaker on the battery and the Solark has a battery disconnect switch built-in. We do have module level RSD which kills the solar output as well as the inverter output when the button is pushed. Does anyone have any experience with this or can they point me to the correct code section or what are others doing to comply with this requirement?
