Net metering rejection notes: help?

So I recently applied for an interconnection agreement with our local power company. It took a few weeks for any type of response, then I was asked to fill out some additional paperwork after they had reviewed my application. I was told they would have a response within 10 business days, then within another 10 business days a crew would be dispatched to inspect the system if it had been approved.

Well, we’re out of the country for the next couple weeks on vacation and I just received the following message via email:

Technical Correction Notes:
Reviewed and Rejected: There needs to be a BSET socket and an AC disconnect between the battery and the transfer switch.”

I’m unaware of what a BSET socket is, nor can I find anything on Google. Additionally I’m not exactly sure how they came up with the disconnect switch aspect. My Sol-Ark 15k certainly has an AC disconnect built into it? They couldn’t have really inspected anything, we’re gone and the system is inside my garage, nor did I receive a notice of approval or that someone would be coming by.

Any thoughts or experience here? Not a huge deal, just don’t know what my next steps should be and I’d rather get the ball rolling while we’re away. Thanks!

That does not make sense. Batteries output DC. They do not generally use a transfer switches. I also do not know what a BSET socket is though I would guess it is for a meter, perhaps the up feed to grid?
 
Solark 15k doesn't have a cutoff on GRID. There is a DC breaker and LOAD breaker, but no GRID breaker. I'd ask for clarification, I can't find anything referencing a BSET socket.

New one on me.. no idea what a BSET is..
 
does your battery have a current limiter? a cutoff switch at the battery?
 
I have been going back and forth with my utility since October of last year. My experienced installer submitted the interconnection request along with all of the documentation. Every three weeks we get a rejection notice, we correct exactly what they are asking for, and re-submit. Then we wait. About three weeks later, we get another rejection notice. We correct exactly what they are asking for, and resubmit. And on and on it goes. I have installed extra components because of them, that my installer says are generally not necessary in a residential design ... and I still don't have an approval. I am finally throwing in the towel as the last correction asked us to change back to something we did during the very first submittal. There is no one who answers the phone and we can't seem to find an empathetic person to speak or even email with. All notices sent to us are without a name on them (by design I am sure). I am convinced because I have a battery back up, they don't want to approve our design, but maybe I am just being paranoid. The good news is I installed CT's and now am getting close to zero-ing out the meter without selling anything back to the grid.

Agreed, but they would provide said meter and it is all external to the home. Nothing I legally have access to.

Correct, but the “breaker between the battery and grid” is not only a super inaccurate term, but exists in both forms.

The battery has zero direct connection to the grid, it has a breaker on the DC side of the inverter, as well as a breaker on the outgoing AC side. Either of which would suffice from what I can tell.

Socket wise, I’m completely lost. All google searches ask if I want to change my search from “BSET” to “best”. I make the appropriate changes to force the search and literally nothing but misspellings from Alibaba listings of totally unrelated items.

This gets a bit technical, I don’t mean to be petty in my answer at all.

Any legally permit worthy lithium batterie is going to have a BMS as well as a breaker, or external breaker (not sure if there are any batteries that are legal without an internal breaker but there probably are).

Additionally it’s long since been a requirement to have an emergency stop switch, which I have that shuts the entire system down.

If we get anywhere near this I’ll be happy to be the guy who follows through with any and all possible legal action, but more importantly make them look like fools on the internet.

I sincerely hope it’s nothing more than a paperwork mistake, hopefully one I’ve made and nothing more.

I haven’t reviewed the diagrams I submitted in detail, however they are the same diagrams the city permitted for the installation (that was a pain in the ass too).

Yesterday being a travel day, today being the wife’s 40th birthday (ollllllllld woman!) I haven’t had the time to dig into the details. I hoped someone would immediately be like, “duh, a BSET meter is this”

Complain in writing to your state PUC. They will generally contact the poco and in turn the poco will stop jerking you around. I hope you have kept all your rejection letters so you can include them with your complaint and show how they are telling you to undo something you were instructed to fix before.
 
All communication is by email, and yes I have kept them! Great advice. Thank you.
 
I re-submitted this morning, I suppose the line diagram I submitted to the city didn’t clearly notate that the Sol-Ark has internal AC and DC breakers, I’d have expected them to not only know that, but also derive that information from the spec sheet they required for the inverter (guess they didn’t read it?).

I also made sure to show the rapid shut down button as well as include a photo.

Still no idea on the BSET portion, I asked for clarification. Should have an idea in the next “7-10 business days”
 
Seems like I have

Seems like I have read the term before - something to do with a socket for a meter showing solar production. Just a vauge memory tickle since I've been reading all about this stuff for months learning.... I will be interested in hearing what they say. .... Seems like I read it on another page when looking into anti-islanding.
