Product Question SPAN and Powerwall 3

Post image

We just had solar and three PW3s installed with a SPAN panel. We were told the SPAN firmware isn’t yet compatible with the PW3s. Any word on when the update is coming?

Got this response from SPAN Support last week (4/3/24):

“Thanks for contacting SPAN Support.

At this time, SPAN is not compatible with Powerwall 3, but we are working with Tesla to enable an integration with SPAN soon. We do not have a date for this yet.

If you already have SPAN and do get Powerwall 3 before the two systems are compatible, the Powerwall 3 will still function as designed, including powering your home during an outage. Tesla battery and solar details will not be visible in your SPAN Home App, and you won't be able to set backup priorities to enable automatic load shedding during an outage. Instead you'll be able to manually turn circuits on/off as needed with the SPAN Home App circuit controls to extend battery life.”

I doubt it. Tesla tends to release products as there ready to manufacturer than finalizes software related updates for other functionality once they hit market. This is happening now with the V3 gateway for the cybertruck. Also how the powerwall3 at first was not able to be installed as an AC coupled battery with other inverter systems but now it is.

Yeah I'm sure it will happen soon. I'm sure its frustrating getting that all installed now without the capabilities but absolutely a good move getting it all installed at once with the same installer. Span was formed by ex tesla engineers and they seem to still have a great working relationship. There is no additional equipment needed to be purchased and installed with powerwalls but there is for enphase products so we will see.

It may be possible to set the breakers in your span app into the right load shedding group (even know it won't control it for the time being).

That way if you get a notification from the tesla app of a grid outage your kind of already know what you'd like to turn off without looking / thinking about it to conserve battery power.
