Bi-Directional Charging

[VSG]

The bigger question is, do any non-proprietary bi-directional chargers exist yet for the US market?

The only ones I was aware of was the wallbox working with Chademo vehicles and the Ford one.

There should be several shortly though, I’ve seen Enphase, Wallbox, and Emporium all working on them.

My impression was that the Wallbox unit doesn't exist yet, at least in the US (I've tried to buy one from them...). Also, Ford is a proprietary implementation.

Yes, I know that some will be available "shortly", but in this case those "shortly" announcements were almost a year ago, which makes the Rivian "s00n" look reasonable.

I think that is the new Wallbox, they had one before that worked with ChaDemo. Pretty sure you coukd get it in the US. I think itcwas called Quaser 2. Or something like that.

Edit
This is the one I was thinking of.

This is the one I'm waiting for as my solar is Enphase and I already have all of the other hardware waiting for it to plug into. But I expect to be paying a premium price being Enphase. It should still be cheaper than their options for 10 kWh of home batteries though. I asked my installer if they had pricing on their next gen 5P batteries. She didn't, but said she recommended waiting for any option to add to or upgrade my current system since they just got back from an installers conference and it was sounding like we would be seeing some pretty dramatic price decreases across the board in the very near future.

Something is definitely up in the solar biz. I'm about to get solar installed. Premium panels and IQ8Hs. The price per watt is 2.65 from a top of the pack installer in my area. Sure I negotiated some but that's an insane price for the NJ area.

I wonder what is causing the dramatic price decreases, or, are we just coming back to reality from the peak of COVID pricing.

Not that hard to figure out. Just look at the latest quarterly results and forecasts from ENPH and SEDG. Lots of blaming NEM 3.0 in CA, which no doubt had a little to do with it, but higher interest rates probably had more to do with it. Those unable to purchase systems outright that were on the fence on costs are now priced out with current loan rates, and demand fell off a cliff. ENPH was hoping their home batteries would solve the NEM 3.0 disaster, but even their next gen battery released this year is still $$$ and only makes the total system cost further out of reach. Since a lot of us now have batteries 10x the size of their home batteries on 4 wheels in the garage, their bidirectional charger is more likely to see a demand surge next year than their home batteries have.

Was it a lot more in NJ before? I paid 2.68 before the tax break (was 1.88 after tax break) back in summer of 2021 here in CA.

If you live somewhere with high electricity rates (ours are stupid high) and good sun I highly recommend solar. My ROI for the system is less than 52 months and I’ve paid less than $100 total between my excess generation credits and the CA climate credits in the past 2 years. That includes the 10 months I’ve had my Rivian.

I got quotes in 2021 at close to 3.50 per watt.

Based on my research on r/solar you got a steal at 2.68ppw in CA. Nice work!

My electric utility pricing isn't crazy high (0.17 cents per kw) but my cost per month has gone up quite a bit since getting the Rivian. My payback period is looking like close to 6.5 years which is fine with me.

I wonder how far this might bottom out though.

I'm hoping to get an early release of the Emporia. I have their energy monitor system and a 17kWh array on roof.

Gotcha all beat on payback timeline. Rural-ish South Dakota, so I'm around 8 cents per kWh. My payback is close to 20 years. That being said, rates are bound to go up which would bring that down some. (I was the first residential solar in our town of about 20k when we installed a few years back. Thankfully a few more now.)

Yeah, I'm similar. Solar does pay for itself in the PNW, but our rates are so low to begin with that the pay back period is pretty long. I think I'm at about 15 years, but when I get a second EV that will be reduced by a bit. I don't mind - my only criteria is that it would pay for itself at some point. It's not meant to be a profit center.
