I believe there is a valid configuration where the main service panel is feeding a gateway 2 at less than 200A and the gateway 2 is feeding load center a 200A. I don't recall who posted about this, possibly @miimura, @Vines or someone whose name is escaping me at the moment.Oh this is interesting. You're saying I can use the batteries and additional Tesla solar to draw more.amps than the 125A PG&E without updating my main service panel? If so, that would be exactly what I'm looking for. As for adding to the SunRun, TBD whether Tesla or anyone would agree to add to it. Trying to find out.
I would think Tesla would have no problem adding a completely independent solar system to a house that already has one, they've certainly done it before but they do change policies on a regular basis.
