Dwelling Unit with 2 meters service upgrade

[RBGS]

Hello,

I need to do a service upgrade for a house from 100A to 200A. I have done this before..4/0 ALU....bla bla bla


However, I have never done one for a house that has (2) meters. The customer is requesting to replace both meters and both panels from 100A to 200A.

My question is the following:
1)Can I use 4/0 AL for my SE cable to power both panels? or do I need to upsize the wire?

2)Do the meters get wire in parallel?

3)Do I need to do individual ground rod to each new panel?

Any help or suggestion will be well received.

Thanks
Jason

One meter appears to be from a solar system? That means only one is from the PoCo? Wouldn't the latter be the only one you can really upgrade?

Or am I missing something in that picture? Hard to tell where everything is going.

Can't read the labels on the subpanels; are they pertinent?

1) What's your load calc?
2) Both line sides, yes.
3) No but you will have to drive two ground rods.

What you have there Jason, is a net meter, which are wired backwards juxtaposed to a normally wired meter, and tagged into the normal 100A house meter. ~RJ~

I think that's probably the much better and accurate way to describe what I was trying to put out there.

Ahh, so it gets a little more interesting.

I was assuming that there was one meter for each panel...since they both have independent SE Cables going into each panel.

*I didn't do a load calc, since I'm upgrading from 100A to 200A.
*Thanks for answering my other two questions.

Is that meter provide by the solar company or the poco?

Yeah, not enough information to properly answer the question. This is a basic residential job so I am surprised that you would have to ask that question. Did you not look at the job close enough before you placed your bid/estimate and pulled a permit?

I'm not being a hard ass, I'm asking some legit questions.

yup, I doubt i'd have much of a career in tech support Mac...

net meters are usually via the prevalent poco , 'cuz they want to make sure they're not giving back what consumers are $$$'ing.

Depending on any mutual 'utilization equipment', you may be required to install meter #3 (discounting the net one) for a house meter, as well as serving panel
