R2 has bidirectional V2L / V2H (vehicle-to-home) specification article

Yes, I think my installer even got that wrong and was touting 80%. Thanks for clarifying. I also asked CoPilot and it's 70% for both, legally. As you point out, there is no cap on the Powerwall and also Tesla has the field data which is arguably more important and that's showing 90-95% after 5 years and 80-90% after 10 years according to copilot. I presume the LFP cells they use are from CATL.

The certification documents for SigenStor’s residential ESS list EVE Energy as the certified cell manufacturer for the modules used in the North American product line. I think EVE is every bit as good as CATL.

I have mine set to consume to a 20% SOC unless there is a power outage and it's in a cold cellar so will never be exposed to heat. Will be very interested to see how it fares. Hoping for 85+% after 10 years.

Anyone have specifics for either R2 or R1 bidirectional charging?

R2 can power your home

According to Rivian, the new Energy Management Control Module is a large electronic assembly that bundles several functions into a single package located at the rear of the battery pack. Among the features included in this control module is a bidirectional charger, which can draw electricity from the grid, which is alternating current (AC), and transform it into direct current (DC) for the high-voltage battery. It can also do the opposite, transforming DC to AC to power an entire house.

“We believe this innovation has the potential to unlock gigawatt-hours of energy storage from Rivian vehicles, creating a cost-effective power storage solution for our customers,” the company said in its third-quarter shareholder letter. In the U.S., the R2 will have a Tesla-style NACS charge port, but as the EV startup is looking to expand its global footprint, the electric SUV could also be sold with a CCS2 port for European markets.

I have owned a Model S for 11 years and currently lease a ZDX, but I am now looking forward to my next vehicle. Several features are particularly important to me, specifically Full Self-Driving (FSD), V2H capabilities, and NACS charging. In my view. My next EV is Model Y however Tesla has fallen behind on V2H features to prioritize Solar and Powerwall sales. V2H is a necessity for me as a backup power source due to the instability of the electrical grid in my area. After watching several test drive videos of the R2, along with RJ's interview, I am very impressed by its bidirectional charging technology, potential for future autonomous driving, and overall design. I am seriously considering purchasing or leasing an R2 within the next year.

Invested in a whole-home 18 kWh battery pack solution to power up my entire home in emergencies. Left to solve was how to charge my battery backup unit while using it.

Curious what brand of battery backup you are using. I have multiple EcoFlow systems, one at 24kwh, one 10.6 kwh, another at 12kwh, and another at 6kwh, but with room to grow two of them to be much bigger. I’m still working towards filling every port with solar and wiring up the house to accept them.

On the other hand I plan to add an R2 to the fleet, not necessarily for the backup power capability, but more for the smaller size and better efficiency for shorter shopping trips and such, preserving the R1S for longer vacation trips and towing big stuff
