FYI, You may be confusing commercial products vs residential products. I asked a couple of LLMs about your comments. Here is Gemini's. CoPilot ended up being similar.

I've spent a lot of time looking at the SigEnergy battery products and how to utilize the kWh battery storage. Check out their details: https://www.sigenergy.com/us/products/sigenstor AI LLM overview.

Great information. Thanks for sharing your usage. I think you're right on the ISO 15118-20 standard as my prev graphic mentioned NACS and CCS1 using it. (cut-n-past of that section below) Regarding the video, I was referring to this one and it appeared to be a CCS1 plug to me. YT video: "Yes...

I'm *really* hoping that the R2 V2H works natively with the SigEnergy products (formerly in the USA as PointGuard Energy). I know there is a YT video of SigEnergy/Pointguard working with a R1T or R1S but I don't think that is an official supported thing but may have worked because Rivian...

Below is what I found in a quick look as I thought there were some standards. This came up with the NACS became a standard. 1) NECs and ISO standards 2) CCS1 and NACS standards DC V2H (UL 1741 inherently) AC V2H (SAE J3072) V2H V2X codes and standards 2025-12-17 V2H V2X CCS1 and NACS...

--> "Skate to where the puck is going" is a famous quote, often attributed to hockey legend Wayne Gretzky (but actually from his father, Walter), meaning to anticipate future outcomes, not just react to current situations, emphasizing proactivity, foresight, and strategic positioning for...

Going through this with a new house build. You have to consider the times when you are not at home (eg. shopping, gone for weekend, etc) or you have a multiday event (eg. need to run to supercharger, etc to refill). Thus a small (10-15 kWh) home battery with 0-10ish ms switch over (handy for...

Sigenergy does bi-directional too. Videos on YT working with a Rivian. [PointGuard Energy (usa) is Now Sigenergy (intl)]

I've seen multiple home battery companies now with chargers connected to them run a wire to a Meter Collar as a cheaper method. Obviously, the utility needs to approve this.

This shows what happens when you try to do that with laminated glass THO.

Rivian V2H support but this is in the works per an interview with RJ (YT link) . Looks like it may be 20+ kW (240v 80a) too! FYI, he said Gen 2 & Gen 1. 1:19:58 if this link doesn't get you there:

10 minute bathroom break is all it takes

Indeed I saw that after my post and sent them details.

Maybe carsized will get a R2 and R3 on their site for nice comparisons. Here is a Tesla Model X compared to a Rivian R1S. https://www.carsized.com/en/cars/compare/tesla-model-x-2015-suv-vs-rivian-r1s-2022-suv/

I feel you as I was having a 100 amp subpanel put in near my future Rivian garage stall. 25.0 kW at 240 volts is approximately 104.17 amps. 19.2 kW at 240 volts is ~ 80 amps tho and that should run every main thing (fridges, garage door, internet devices, etc) in our house since we decided on a...

Rivian owner indicated that they pulled over to let some people pass ... then ended up with the softer sand.

Wondering about getting running boards as form of protection from door dings. Assuming you get a set that stick out enough for that. Also for aging friends and relatives.

ASIDE: Rivian V2H support but this is in the works per an interview with their CEO (YT link) . Looks like it may be 20+ kW (240v 80a) too. 1:19:59 -
