    Frustrating. I have to say, I find it kinda ironic too - This kinda thing isnt what Texas is supposed to be all about

    We have it very good here in upstate NY; Inspections are mostly 3rd party. If you dont like the inspector, you can call a different one!

    Yep, a separate meter read by the POCO connected upstream of the customer's meter. This is the "brainchild" of an engineer in a small POCO who wants to be able to compensate for PV production at a different rate than what they charge for energy. Austin Energy does this, but they put the PV meter inside the customer's meter and just do the math.

    I wish that were the case in more places, definitely not happening in the western states I work in.

    This can work against you too if the AHJ selects the 3rd party. There are several AHJs in SoCal that use the same 3rd party review company who has strange PV interpretations. So instead of having just one problem AHJ every AHJ that signs up with this company adopts the same problems. When someone protests to an AHJ they just say they go with whatever the 3rd party says.

    AMEN,

    Can't imagine who you might be referring to

    There is an AHJ we deal with a lot who shall remain nameless. They have two solar inspectors, and their interpretations of the NEC sometimes are... special. To make it worse, their interpretations are not the same. Over the years we have learned which NEC compliant designs we simply cannot implement, and in many cases, which one of these guys we have to get in order for an installation to pass inspection.

    They have no technical oversight; everyone north of them in their chain of command are administrators with no technical expertise; protests fall on deaf ears.

    hopefully you make $ for your troublesome working conditions -- I usually correct those who say "just want to make you happy" with Code is minimum not personal
    CircuitRyder --- Unfortunately not all good ideas are code enforceable.

    In our areas most of the inspectors have worked with their tools in the past and have 1st hand experience with a good portion of the Code and with working with inspectors themselves. I kinda feel for the Solar guys as many of the inspectors, like myself, don't have that "on hands" experience with Solar and it's certainly not the easiest Section of the Code to understand and available classes can quickly go over your head. Maybe Mike can come up with a program "Solar Inspections for Dummies"
    At my age, I'm accustomed to restaurants asking me to pay in advance, but now my bank has started sending me their calendar one month at a time.

    I can't find the thread, nor remember the poster

    Apparently there's something of a interpretational problem between 705 and 230

    IE~ we don;t know if it's treated as an sds or not

    Not sure if any of this has been brought to the attention of the 'powers that be'....
