Home Wall Charger

[TheKoz]

Newer member to the forum and just recently purchased a R1T and Rivian home charger. Just an FYI that you can get a Rivian home charger on eBay for much less - used or new. Another option to consider.

Also new to the forum. Took an R2 test drive today and I asked about being able to charge it on my Tesla Wall Connector (Gen3 installed in 7/21). I was told that it may not work with an R2 given the age of the Wall Connector. Has anyone experienced problems with an older Gen3 charger and an R2? I apologize if I missed it reading through the posts.

My main factor is that I have solar panels and powerwall batteries on my house. My local utility co-op does not offer cheaper time of use rates, and does not offer net pricing, so I want to charge in the middle of the day, and use lower amps that use less power than what I am producing at the time, especially if I am not in a hurry to get to 80%.
R2 will not let us reduce charging speed to 28 amps if my home charger is on a 60 amp breaker. My old Tesla gen 2 charger did not have that capability, because the Model Y allowed me to change.
my Lyriq, like Rivian, does not give me that option, so I installed an Emporia. Through the app, I can set at 28 amps, but also increase back up to 48 if I need a quicker charge.

You can set a maximum charging current in the R2 itself, either for all charging sessions or the current one. It's not tied to a specific charger though, so you'd have to remember to adjust it up/down for each charger that you use.

Sounds like you've already installed an EVSE that does what you need, but there are also some that integrate with solar/battery systems (or have CT smart meters) and could dynamically limit the charge based on solar production/home usage.

Thanks. I stand corrected...

Rivian Assistant told me not possible to change charging amps

This screenshot is for an R1, but the R2's energy page looks similar. The "48 Amps" button at the bottom of the left panel is what lets you limit the charging current.

The Gen 3 wall charger will work as long as you have the setting for charging all cars, rather than just Teslas or Teslas based on their VIN number.

If you're getting a Launch Edition and you live in specific states, you're able to get RIvina's mobile charger (NACS) for free. It will charge your Rivian at 32 amps (with the right electrical connections in your home) no problem from what I'm hearing.

Rivian Assistant told me not possible to change charging amps

The Assistant is wrong. I just watched a demo and it clearly showed the user setting the amperage to 32 amps.

If you schedule the charging session in your vehicle, it lets you set the specific amperage you want. So it will always charge at that amperage as long as the schedule initiates the charge. If you are not using a specific scheduled charging session you need to set the amperage before you plug it in.

OK - apologies. I stand corrected. I had asked Assistant before and was told no.
After reading posts here, I asked Assistant again and got this answer:

Yes, you can make that change directly in your R2. The vehicle’s Energy App or infotainment display lets you manually set the charging amperage, so you can lower it to 28 amps even if your Level 2 charger is installed on a 60 amp breaker. This gives you control over your charging rate, helping you match your home’s electrical setup or manage heat.​

I should delete my earlier post to avoid confusion...
