Is this possible? Our local utility offers $0.024 power after 7pm until 12am but $0.096 during peak. Trying to figure out if we use a PW to only pay the $0.024 or not.

I do have a 3rd one coming, so that way I can allocate two of them for Time-Based Control, and keep the third one's capacity reserved for a power failure.
Do they actually let you do that, or would you have to have a second system/energy gateway to support that?
Mine is even better. $0.14 during day and $0 at night. Yes free at night.Is this possible? Our local utility offers $0.024 power after 7pm until 12am but $0.096 during peak. Trying to figure out if we use a PW to only pay the $0.024 or not.
You can ask your installer to install the battery as "standalone" instead of "paired" storage. Then, you can freely charge from the grid as you're not taking the federal-credit rebate.One caveat that might not be obvious: if you have solar, you can't do this. Powerwalls installed alongside a solar system will (currently) only charge from solar so that they meet the requirements of the federal tax credit.
Wayne (wwhitney), in the forum, is doing that. His problem is now how to get TBC working when you DO have on-site solar, but the PW isn't officially installed/paired with solar support ...
Hey Wayne, I'm installing via third-party installer as it was a tiny-premium to go with them vs doing the SGIP dev myself. I'm was supposed to install by June, but looks like Tesla's battery inventory is still depleted.I'm looking into having the Powerwalls configured as standalone, even though I have solar, but I haven't actually asked Tesla about it yet. NuShrike, what did Tesla tell you, and when is your install? [Sorry if you've mentioned already in another thread.]
Cheers, Wayne

I did ask my installer whom confirmed with SGIP: as long as the final ICF says standalone, that's the only document that matters in defining what's installed.
As for TBC issues, I think at worse I'll just stay with self-consumption, with a calculated reserve (after doing a few annual simulations via SAM). That should allow night-time charging, and proper daytime discharge.
At best, play with the APIs to programmatically do what TBC isn't doing. IFTTT would've been nice here.
This federal tax credit only applies when you install the batteries at the same time as solar panels right?
