Why was Charger capacity reduced ?

[Ragman]

Those are the hours my solar panels are sitting idle, I have 47kw on my roof and my house batteries are taken care of between 10-11. (85kw 100% full)
I’m also looking into DC charging….

We have three of the smallest DCs available - won’t buy another. They work fine at a net 22.3kw however you cannot precondition for departure time. DC is on/off there is no truck side control like AC.

They take a 150 amp circuit for a 240v install. All in you are $10-15k usd.

Best bet is factory fleet order with dual chargers - it’s not worth it to everyone but I’d bet 5-10% especially 100 mile a day commuters its worth the 2nd

The majority (99%) of people are using regular home grids and or a home grid supplemented by Solar to charge, the key to home DC charging I think is solar direct. Again I think I’m in a unique situation to do this as I’m fully off grid….
The price of DC to DC that I’m looking at is no where near that and it should give me up to 40kw. (Potentially)

I'm very interested in learning more about the DC to DC option as I too will be off grid once our new home in Hawaii is built. I always intended for the Lightning to be a component to this off-grid solar plan and hated the DC-to-AC-to-DC (and maybe back to AC!) waste.

PM me please if that seems more appropriate. Knowing more about what you have found may help me make some initial decisions for our solar setup.

I too am interested in the solar DC-DC solutions that could be emerging.

The OP setup is likely high dollar, based on off grid needs. But the off grid world drives the technology.

In my case, the farm's ER Lariat with inverter can also power the farm (at 7.2 kw) in a pinch. At least the lights and freezers and whatnot. Or you can tap the 131 kwh battery and tank up the house batteries via generator port -- 131 kwh of battery is huge. Even the OP with a very large solar setup has "only" 84 kwh batteries. (this is truly huge for a residential installation)

BEV vehicles that can deliver back watts can really fit into a bigger system. Or any system.

Thank you for that answer, that is what I was looking for. Much appreciated.
Simultaneously charging is something I have not tried. I will look into it. Now in the summer times I also use about 5- 8kw running the house, I have a few AC running 24/7…..
We have clear skies and sun 350 days a year. Although we do get some cloudy days we have not had any rain in the last two years. But lots of sun.
I found a 40kw DC charger specifically designed to charge a EV DC to DC from a big solar array for about $1,500. (Not 6 figures) I’m waiting for the manufacturer to get back to me to confirm, specs, pricing and availability.
Thanks again for your reply…

No, no, no! From all the metrics and local solar environment you’re quoting in other replies, just use what ever AC EVSE and run it all day. No way would I get a special DC EVSE at $1500 when you have gobs of home battery, near perfect solar and an excess of panel power. I would be charging my truck every moment there are photons hitting the panels with your setup.

I’ll post the details here when it all pans out….

I am SOOOO wanting (and waiting) for this to pan out!....
