There are easy ways to bore under a driveway. Impact moles are pretty amazing. No need to tear it up. I bet with a creative contractor it would be a lot less than $30k.I’ve been considering SPAN as a potential solution to automated and allowed load shedding. We have a 200a panel and several upgrades have put us near the edge. 320a is over $30k due to underground service, distance, and going under a concrete drive that would need to be ripped up.
Curious if others are having problems with the system.

Is there a signal available somewhere that could be used to disconnect the relay? A Swim spa (swim current, filtration, heat) is one of my larger loads on my highly loaded panel.I was reading about the other smart circuit breakers. They allow you to trip them but you need to be there in person to set them back. I wonder if there are any that allows you set remotely. My use case is my swim spa. In the case of a grid shutdown, which is common in Sierras, CA, I don't want the swim spa to continue to use power, but I want my well pump to be able to come up. they are on the same subpanel I couldn't get them separated when we were getting the powerwalls. The SPA breaker is 50A so maybe I should go with a relay solution.
I believe the Savant Smart breaker solution will do this on and off actuation for you for an up to 60A breaker. The hardware is around $1000 to a contractor. I'm not sure if they will sell directly as I haven't gone further than seeing them at trade shows.I was reading about the other smart circuit breakers.

That is pretty straightforward to do by installing a contactor (a large relay, with the option for lots of extra features) that is turned on by grid power and using it to switch the spa on/off. That should be pretty straightforward for most setups, and one most commercial electricians should be able to install. @Vines what do you think?I was reading about the other smart circuit breakers.

A sufficiently sized Normally Open Double Pole Single Throw (NO DPST) relay and control circuitry to get voltage sense and contactor actuation from the grid side to the circuit you want to turn off would also work. As my boss likes to say "we could solve that problem with a relay!" In the old days with Sunny Island or Outback battery backup systems, we would need this sort of load shedding to make the systems work well enough.That is pretty straightforward to do by installing a contactor (a large relay, with the option for lots of extra features) that is turned on by grid power and using it to switch the spa on/off.

If you want WiFi control as well, that would get more complicated.
All the best,

My SPANs and powerwalls are still communicating with each other. Good luck!Pretty happy with our SPAN panel, so far. One of the selling points for me was their ability to integrate with the Powerwall.
Alas, about four weeks ago, the SPAN app reported that it lost communication with the TESLA backup.
SPAN support has been pretty responsive ~ 20 email messages from them so far, and while there is data on ethernet between the two panels, SPAN support tells me they are receiving an error from TESLA “incorrect password” even though the default password has not changed.
Pretty frustrating from my end.
I contacted TESLA, and was told they don’t know anything about SPAN.
This makes me wonder if the SPAN-TESLA connection is informal, and TESLA made no promises to leave the maintenance interface (which SPAN is using) unchanged, and changed it recently.
Anyone here shed any light on this conundrum ?
Thank you.

This likely means it's accessing the unofficial Gateway API.
Unknown, sorry. I’d reach out to SPAN. I’ve had great success with their customer service. That said, I assume you’re still using a Gateway 2 so I’m not sure what difference it would make to the SPAN panels but I’m not an expert.Q - I've read that Span firmware isn't yet compatible with Tesla Powerwall 3 (which is what's being installed in 2024 and onward). Anyone know when that'll happen? I'm in the middle of a Tesla Solar installation process and going back and forth on whether a main panel upgrade is needed.
