Finally starting my 2KW GT system

[NeilTheCop]

Well an Empire Electric guy came out to look at my setup. So maybe I am getting closer to getting grid tie approval. Quick question, have any of you that installed you own systems had much trouble getting grid tie approval. Is this normal. I am glad we are erroring on the side of caution. I am just a little surprised it has been this much of a challenge.

On the up side I want to get this right the first time, it's always cheaper that way. The guy that came out yesterday did say we would have a double meter setup in our existing meter box. he said ti would fit in what we have. That is good news. We have a brick house and the meter box is inset in the brick. Changing that out would be a mess. He also said they hope in the future to have a true net metering system, but as of right now their billing system cant handle it. My bills will all have to be done by hand. So I guess I will need to keep close track my self. Another plus for the enphase, as it tracks and records the output for review at anytime.

May I suggest you send them a copy of, The Net Metering and the Easy Connection Act

And ask them what part are they having problems with.

The biggest thing I ran into was the wiring diagram. They wanted a professional diagram. I don't know any electrical engineers, and my first several attempts were judged sub par. The one above has however met with their approval. If any viewers of this thread are going through similar approval issues, that is a decent starting point for your wiring diagram. Your interconnect service may be 4 wires rather than three like mine. My neutral acts as a ground. You also may have to go through a transfer switch (utilities prefer you not use transfer switches for cut off switches). Transfer switches have a somewhat more elaborate diagram that a simple cut off switch.

I will say that all the rejections did cause me to look deeper into my existing wiring. I now have a much better understanding of how things are wired in my setup, and some of my original thoughts on my first diagrams were wrong. My system is actually going to be much more simple than I originally thought.

The engineer did give me a call Friday evening, and he did not use the words approved, but he seemed to indicate everything now looks in order. I should hear back this week if I am pre approved. I just need to get my equipment ordered by next Tuesday.
