Enteligent now has a DC-DC Solar EV charger for pre-order

[SpaceEVDriver]

I've been wanting this for a while now, but I'm having my Lightning's Power Station Pro EVSE installed next week. I won't be able to justify the $2250-$2500 expense of this any time soon. Also, hilariously, the spec sheet says it can't operate at my altitude.

Sounds like they should rename it to Vertigoeligent.

This is really cool. Thanks for sharing. I get another electric car, then this would be a no brainer to install.

Thanks! I thought I'd posted a screengrab of it in the first post, but apparently that didn't carry over.

Nice, but the direct solar charging has a serious blind spot. Whe is the sun shining? When you're at work!. How are you going to plug into this device at your house when you're at the office?

Unless the intent is for deployment at workplaces?

There are conflicting statements from the manufacturer but one of those claims is it's not just solar, but also can be battery-powered. There are issues with that claim if the MPPT inputs can't be switched to a different response to a battery-powered DC source.

Mostly these seem to be aimed at small businesses, off-grid locations, etc. At least for now. They claim there will be a battery-powered DC-DC option later this year.

It is only rated for 25A to vehicle. That means 8.125kW at 325V, not the advertised 12.5kW.

It also maxes out at 550V to vehicle.

Fairly new start-up, specs may be changing. Interesting product, but I’m not quite sure what it does?
I guess it would be DC slow charging?

Yes, EVs are a useful place to send solar energy without the hassle of a grid interconnection.

As long as the EV is at the location where the array is at....
And as long as the array will sit idle as long as an EV is not connected to it...
And as long as you're happy with whatever level of solar irridiance might exist that day...

Great product.

I'll get the Solaredge DC charger... all the benefits of DC to DC, none of the waste.
Or one of the 20 other similar products that come to market in the next year.

What I'd really love to see is panel that's portable for camping, or perhaps mounted on the roof or a roll up tonneau cover.

As efficiencies and price shift, the ability to charge even a fraction of your daily commute whenever you're parked could really become inevitable, especially for vehicles with large roofs or pickup beds.

Elon Musk once Tweeted that a CyberTruck cover could be designed with solar panels large enough to power a typical day's commute, but it never happened.

Mobile Solar is never going to happen in a fashion that has meaningful power output.

Not immediately, but it's a lot easier to pull off on a vehicle this size.

Here's what Musk said a while back:



It was all over the Internet at the time he made the Tweet. Of course, it never happened, but even a panel the size of the roof of a large truck or SUV could generate at least a handful of miles per day. The way I see it, as long as it generates more power than the price of the panels, it's a good thing.

A lot of people say this but this misses the point. It's not about the power, it's about the sum total energy.

Let's say we embed 444 watts of solar on a BEV. Transforming from 48 volts to 400 volts is about 90% efficient, netting 400 watts.

The average daily usable sunlight across the US is 4 hours. This accounts for all the variables, but obviously is just an average. Assuming that average, the daily input to the vehicle is 1.6 kWh.

That 1.6 kWh seems useless. But over 365 days, that's 584 kWh, or almost 4.5 Lightning ER battery fills every year. For a truck that nominally gets around 300 miles, that's around 1200 miles of range per year; less in less sunny states and more in sunnier states. That 1200 miles of range is about 8% of the average distance driven per year. Even if the panel only generates half of that energy, it's still 4% improvement to overall range. And if integrated into the body, it wouldn't weigh enough or create drag enough to measurably reduce efficiency.

It's not about the instantaneous power, it's about the sum total, slow-yes-but-consistent, trickle of energy.

I'd buy an upgrade option solar tonneau cover for the Lightning.
