Sorry to get your butterflies all a flutter, hemi.

New update detected today on Netzero for both Powerwall 3 and 2. Same firmware version.

26.26.0 d2487d0a

Here's hoping....

This looks like it might be a firmware update to allow Powerwall 2 and Powerwall 3 to operate together. Previously all Powerwalls in a system had to be of the same generation.

As for Powershare capability, I think the software update rollout might be phased with region/utility provider based rollouts so Tesla can manage utility specific conflicts one at a time (or at least not everyone at the same time).

Wouldn't that mean Tesla is prioritizing Cybertruck to grid over delivering Cybertruck as home backup during grid failure?

It probably makes sense to roll it out concurrently, all as one package. Tesla succeeds because they know how to deliver value efficiently.

The economic case is much stronger for grid support than emergency backup. Most people can't reasonably afford to pay big bucks for an edge use case that rarely happens, even though I understand why people want it (including myself). Sharing energy with the grid in times of need has huge economic benefits when looked at from a first principles perspective and is the driving force behind making this all work. Delivering it efficiently, all together, helps keep Tesla's human resource requirements low. That is their most valuable asset, their employees. They want to empower the fewest number of employees to do the most good. That's how value is delivered, not by getting mired in deployment strategies that increase overhead and employees required. When teams become too big, everything slows down and grinds to a stop.

Those are good points. It will be interesting to see how many grid cycles Tesla will allow the truck's pack to go through.

Here is hoping. Roll out here where I am as in a cooperative with pretty much no permitting ha.

The CT allows us to take it down to 5% actually in OowerShare use mode.

I don't think we will get any usage of the CT unless the grid is down or your off grid officially as well. Less cycles for everyone of course, but great assurance for outages.

Got my work around up and running today - fire season is here and I need to know I have my well working.....

Thanks for the awesome video. Why does the PV solar input have to be cut out? It would obviously be awesome to still make juice from the sun.

My installer said if the micro inverters light up with AC that the panels could start to generate, that could try to back-feed then generator (aka cybertruck) - I am not a whiz at that stuff so I took his word for it!

But you have a powerwall then the straight dc from the panels is fed right into the powerwall Mppt connectors I think. I’ll just hang out here till @mongo or some other Sage has an answer. Lol.

The PV is a separate Enphase micro inverter system (combiner? to the left of the main panel), not DC into the Powerwalls. So maybe PW2s or PW3 added after the solar was already there.

Yep, bed outlet (really, the software) might not like being back fed.

Powerwalls were here when I bought the property. I added the solar and thats when enphase equipment was installed. Always learning and appreciate any insight!
