I disagree. There is a whole lot going on with Solaredge's MID, which they call a backup interface. These different solar vendor MID offerings are not at all comparable to gang electrical boxes from different vendors. Do you install these systems?Forgive me I don't want to sound impolite but no sir I am not missing anything, I understand exactly whats going on. I think you are missing my point that when brand x and brand y make you purchase exclusively their products when they make products that do the same thing that is is vendor lock in.
All MID's generally do the same thing like all one gang electrical boxes do the same thing, they might be different sizes of 1 gang electrical boxes but I can buy any brand of electrical 1-gang box and install a device like a receptacle or switch with a industry standard yoke.
There is nothing really special or magic about those MID functions, on/off , voltage, current sense, in what I understand a MID to be, which may not be much.
So there seems to be no logical reason to have a vendor 'ecosystem' other than to lock you the installer into their ecosystem.
They don't even need to agree on and draft yet another new industry standard, SunSpec/Modbus already exists. It sounds more to me like vendor x changing the size of a one gang box so now I can only buy vendor x branded receptacles, as is the case in the plumbing and heating world. I see it and I don't like it. I dont want a 'ecosystem' for energy storage stuff any more that I want one for one gang boxes.
This; for better or worse, that is indeed the bottom line and there can be a lot of variability. When I was designing PV systems all over Texas, we had an evolving on line 10 column Excel spreadsheet with a row for every AHJ (POCO, municipality, etc.) that we had to deal with. It was three or four sheets long.Didn’t read all the responses. I can say though if the utility says no, then it’s a hard no.
The utility refusing meter adapters at their own meter should be a different category than the utility refusing load side equipment.Didn’t read all the responses. I can say though if the utility says no, then it’s a hard no.
When I worked for the utility I did the solar meter changes and commissioning for tests to keep it on. If it failed the test, they weren’t allowed to turn the system on. If we found a system that wasn’t approved by us, we had the right to remove all power from that structure until it was compliant. Jus sayin..
It's all the same to me. Code says you can do it; AHJ says you can't. Happens all the timeThe utility refusing meter adapters at their own meter should be a different category than the utility refusing load side equipment.
