24 VDC PhotoControl and UL listing

[Solarkid]

I have an AHJ that is insisting that we spec a UL listed photo switch (dawn to dusk) for a commercial client. The system is a 24vdc solar system with batteries therefore no transformer. I have sourced a number of 24vdc phot controls but none are UL listed. Can anyone explain why these do not need UL listing (please supply reference if possible) so I can get this info to my AHJ...Thanks

Not on topic but why would a solar lighting system need a photo switch in the first place? Most of them it is built in.

110.2 and the defintion of "approved" permits the AHJ require the use of listed equipment.

Are There Any manufactuered

I don't question the AHJ's decision, I just can't find any manufactured photocontrollers that are 24VDC and UL listed. There are a number out there on the market but not UL listed. If I can provide a reference to the AHJ as to why this situation exists, he says he will listen...just can't find the references.
(As for the first response, can't find a charge/lighting controller which meets the charge controller requirements of 45 A)

You are correct and I am humbled!! What can I say......other than DOH hmy:.
Just didn't read far enough in the user manual.
Thanks.

But I'd still like to know why manufactured 24vdc photocontrollers don't need to be UL listed

isn't UL not required on anything operating at below 30vdc?

A listing is specifically required for lighting systems operating at 30 volts or less. 411.3
