For AC input, the ground wire is the one coming from the 6/3 wire feeding the inverter from the main service panel (which has the neutral and ground bars bonded with a thick screw and the ground wire connected to a grounding rod). For AC output, the ground wire is the one coming from 6/3...

It offers overload protection

So would it be safe to ground the proposed system to the ground bar in the main service panel, since this main panel itself is grounded to the Ufer?

The existing solar system is grounded to a ufer in my house through #8 AWG. Do I need to implement a separate grounding to the proposed solar? Thank you for your patience with my questions.

Do you know where or who can provide help with preparing such plans?

Ok. As you previously suggested, I think I'll move the EV charger from the subpanel to the main service panel while keeping the rest of the loads on the subpanel. Well, this was suggested by another member who has the same inverter...

Updated proposed configuration diagram per previous feedback. Given the new 225 amp subpanel, is it ok to have most of the loads at the subpanel, including the EV charger, as indicated? Is the 10 AWG ok for the proposed 14 PV solar panels? do I need to go higher (8 AWG) with the wire size? Can...

So assuming I use a Square D 225 amp new subpanel, how do I feed the new subpanel with the AC output from the inverter? Do I just replace the main breaker of the subpanel with the 2P-60 amp AC output from the inverter?

Existing subpanel: I'm considering this Square D panel as a replacement: https://www.homedepot.com/p/Square-D-Homeline-200-Amp-40-Space-80-Circuit-Panel-w-3-20-Amp-Single-Pole-2-30-Amp-Double-Pole-Breakers-Cover-Value-Pack-HOM4080M200PCVP/204836379

How about replacing the existing subpanel with a different one that has a main breaker? I can then use the 2P-60 amp ac output from the inverter as the subpanel main breaker. Would that work? I need a new panel anyway as I'm running out of spaces in the existing one.

Thanks for the feedback. The subpanel is a main lug load center with no main breaker, how to feed it from the inverter output?

Hi, I included a diagram in my previous post. Thanks for any help.

I'm attaching a diagram of the existing and proposed configurations. Basically, moving most of the loads to the subpanel, then adding a 2P-60 amp breaker for AC input to the inverter pulling from the main panel, adding a 2P-60 amp breaker for AC output from inverter feeding the subpanel, added a...

"IOW the grid connection can only be connected to AC in." So AC input should be pulled from the main panel (grid) into the inverter while AC output should feed from the inverter into the subpanel. is this understanding correct?

"You cannot feed the output from a hybrid or off grid into that panel." I plan to configure my hybrid inverter to zero export. Would that work then?
