Solar Ready Meter Panel says 100A Availabe

[MJRobinson]

So while researching the latest on Solar Ready Main Service Panels, I ran across this, with the claim that's it's 100A Solar Ready.

Get this:

This box is basically a standard 200A box with a 60A load side tap. Here is how you can get 100A:
60A from the top dedicated solar section.
40A from the main bussing. (200A Bussing x 120% - 200A Main breaker = 40A solar)
You will need 2 solar breakers to get 100A, 1 x 40A, 1 x 60A.


Thoughts on getting this by your AHJ?

I'm sure I could get that by most of my AHJs, except the ones that aren't yet recognizing the centerfed option on a dwelling. But it's pretty lame. I reckon it would cost all of $1.50 to just make the auxiliary service disconnect 100A.

By the way that's a line side tap to the 60A.

I had looked into those and apparently, from what I gather, there are 2 options. A 40A PV buss and a 60A PV buss. The other thing I found is that it’s about $350 more than a comparable meter combo service. What I haven’t figured out, said from the 2 more breaker spaces, why you would use one and if and when it’s required.

Tagging along.

Seems like a Mickey Mouse way to do it. But in a residential system how often do you really need more than a 60A CB? That would allow for a 11.5kW AC system which is a pretty large residential system.
