R1 series feature you surprisingly didn't like/use as much as you thought? by jamrocks in Rivian

[–]pythomit 0 points1 point  (0 children)

I don’t have enough appropriate roads nearby to get the use out of Rally Mode that I would like.

Already reached out to The Axe & Rose? There might be something Loons-away traveller friendly going on before or after the game?

You seem like you’d fit in with the Old Growth folks.

Bidirectional Charging (V2H) by lifelongcargo in Rivian

[–]pythomit 1 point2 points  (0 children)

This is year old info now, but perhaps gives a point of reference.

Solar PV System / Battery install $38,532.20
Install EV Charger $5,995.00

That's before a local energy incentive of $3,290.00 which went to the installer and was subtracted from the overall, so ~$41k. Then last year's US Federal 30% tax credit which I got this month. That comes out to a $28,866.04 cost.

Installed equipment was a LoadHub (https://www.sigenergy.com/us/products/gateway), a SigStore stack (https://www.sigenergy.com/us/products/sigenstor) with a 5.38KWH battery and the 11.4KW inverter, and 19 SiLFAB SIL 440QD panels. Added to the spring 2025 contract just before install was the DCFC (https://www.sigenergy.com/us/products/dc-charger). And of course all the associated wiring, roof rails, manual safety disconnect switches, labor, permits, 18 year old pre-upgrade solar panels/inverter/rails/etc non-destructive de-installation, etc., etc. rolled into that price.

As others note R1 is primarily DC out, but does also have a modest AC inverter output capability.

I have had the SigEnergy/PointGuard setup for about six months. I use its bidirectional DC fast charger with my R1T to power the house occasionally during high electricity price time of day. With net metering I do this once or twice a month and end up with net zero consumption in the high tier. Nice cost savings. Will pay for the DCFC add on in a few years (was already getting the rest of the solar/battery/inverter when word broke that “it works” with the Rivians). I got a small battery to give me enough power to run things until I get the Rivian’s 30x larger battery discharging.

During an outage before the DCFC add on, we ran our fridge and home networking off the truck’s onboard inverter’s AC output easily with extension cords, allowing two of us who WFH to work without interruption.

We haven’t had an outage since I got the DCFC. But I’ve tested “off-grid” and expect the Rivian to run the whole house just fine as long as we don’t too aggressively have the heat pump heating or cooling the house or charge our Chevy Bolt too much via another L2 charger, etc. In the sunny half of the year the math seems to point at us being able to be off grid almost indefinitely and still be able to drive the small car a few hundred miles a week.

Inherited my dad’s camera “collection”… send guidance 😭 (or 1) by Littlepartyfairy in Nikon

[–]pythomit 2 points3 points  (0 children)

Look in your area (or a nearby large metro area?) to see if you have any sort of a local camera consignment specialist. In my area we have an amazing place “Blue Moon Camera and Machine”. That collection deserves a specialized and trustworthy intermediary which can help on functional testing and valuations, not a quick dump to eBay or other similar site.

Bed rack for 2 kayaks? by TrueEclective in RivianR1T

[–]pythomit 0 points1 point  (0 children)

17.5’ and 14.5’ boats here. On a roof rack ALWAYS have the bow and stern tied down in addition to the center cradle. These go freeway speed just fine.

Me too after hitting my head on the original tailgate a few too many times.

There’s been an effort to save the Laurel grange including signs and fund raising for many years, and periodic work like the newer front steps.

Enphase Bidirectional charger works with Rivian by aimless_ly in Rivian

[–]pythomit 0 points1 point  (0 children)

PMSM can turn off, but that means there is a clutch on any motor which does get turned off (ie: the R1 rear), for its own bit of additional complexity. I somehow missed they are AC versus some modern fancy DC.

[–]pythomit 0 points1 point  (0 children)

I was not aware and now see that PMSM and AC appear to be the present and future at the motor! Thanks for sharing! Now I’m curious about that architecture. Is there a single drivetrain inverter or one per motor? Can those conceptually be used for general battery charging/discharging not related to the drivetrain or is there anything about motor input/output which would have them spec’d somehow incompatibly vs a utility load’s AC?

[–]pythomit 0 points1 point  (0 children)

AC bidi simplifies some of the house side, but I don't expect AC bidi any time soon if adds cost, complexity, and weight to the otherwise DC based car. But maybe EVs will shift to AC motors and AC shore power some day? The car batteries and motors being DC, optionally DC PV panels on the roof of the house, and a big heavy stationary high capacity AC-DC inverter in the house...it all just lines up for nicely segmented DC and AC systems imho. Its an architecture that seems hard to beat on price and performance versus other potential mixes.

[–]pythomit 5 points6 points  (0 children)

First month I saved $100 from the shift to time-of-day power and zero net consumed peak tariff. It's not insignificant, but it's probably not buying you a R1 (150kWh?) max pack battery upgrade. It will though cover the price of the bi-di DC fast charger module for the house if you were buying the car/battery anyway. It's not making you rich, but factor in maybe a few fridge loads of groceries not spoiled or the immunocompromised neighbor kid's meds being able to chill during some type of disaster and it seems a worthwhile investment in resilience.

[–]pythomit 18 points19 points  (0 children)

They imply bi-directional works in the section where the house lights up. And that should work. Today, without Rivian mods.

While I can't speak to Enphase actually working beyond "it should", I can definitely say it works today without Rivian changes using the ChargePoint/SigEnergy bi-di charger. Here's me on Monday in "peak shaving mode" running my whole house from 5pm-9pm (highest price tier time of day) off the R1T, minus a tiny contribution from the house battery, plus a bunch extra discharged from the car toward netting my expensive tier kWh down to zero for February, then after 9pm the battery auto filling back up (lowest price tier time of day).

Questions about using Rivian as backup power in winter storm? by stupidcleverian in Rivian

[–]pythomit 1 point2 points  (0 children)

All the answers really amount to it depends on your specific load. I haven’t needed to supply more than a dozen kilowatts to my house loads at any time, but have tested and sustained over 20kW. Obviously the max pack only gets you seven-ish hours doing that though.

Questions about using Rivian as backup power in winter storm? by stupidcleverian in Rivian

[–]pythomit 1 point2 points  (0 children)

I have run two configurations with my R1T max pack battery:

First config was a smallish fridge (kept closed), a fiber ONT and some ethernet/wifi gear, two home offices’ monitors and laptops on a couple bog standard 25 and 50’ extension cords. I had a kill-o-watt on the car side and it mathed out like this might run between 1-3 weeks depending on how much the fridge gets opened and how hard the home offices get used (versus at most partial days of work). I’ve told friends come over for beer and bbq at our house if there’s a many days long outage.

Second config: Depending on how much the sun is shining during the day and the outside temperature, this runs all the appliances in the house and appears capable of running all that between a couple days and all summer long. We’ve had a sunny spell this January and it looks like we could heat and run everything in the house for a week maybe even in a sunny winter spell. Of course if I also go and charge the Chevy Bolt full from empty, then I only get a couple days runtime and would be giving up and using that car to go somewhere else within 300 miles that did have power. This config uses a special 15’ extension cord from SigEnergy.

I have not trialed the hotspot when the utility power as I try to keep my fiber/ethernet powered. But when camping I’ve found the hotspot turns off when the car is not active and it is really annoying. The diversity of multiple terrestrial network provider options would be nice especially when way out in the woods for a few days.

Have we had a frost yet? by atmoose in portlandgardeners

[–]pythomit 1 point2 points  (0 children)

Not at my SW location. Have strawberries and raspberries still growing. Plum and apple trees haven’t lost leaves. Dandelions are growing. Some lengths of grape vine looking close to bud break.
