I currently live off-grid and this is my set-up
5.400Kwh Solar (peaking at 6200Kwh)
70KWh Battery bank
I can Invert 4.4kw continuous(wanted to upgrade to 8.8Kw)
almost every morning my battery bank is at 100% State of Charge around 9:30-10:30am and the rest of the day my solar is doing nothing which is fine for charging my future Tesla Model 3.
Here is my problem, instead of upgrading to a second Inverter in parallel I was hoping I could divert the solar 150VDC to charge the Tesla with an adapter of sorts.
This way I'm not passing the DC through my Battery bank then Inverted it to 240VAC(2x120VAC) which the car would change again to DC with the on-board charger.
Does one exist? I am not grid connected so most so called "PV to EV" machines wont work because they still use AC I believe.
Note: My charge controller already has a built in relay switch that I can program to open/close with the State of Charge of my home battery bank, this way it could activate some sort of diverter to power a DC Charger?
