Hi Larry and All, You sure can charge your EV from solar, even directly if you match the solar and pack voltages. Or you can go dc to dc or dc-ac and back to dc. On a dc home you can chose low to high voltages. If you pick around 350vdc solar string inverters and production EVs use and can use crashed EV packs. 1kw of solar gives about 20 miles/day, more in the south, summer, less in the north, winter. A clean fueled generator like B100, etc or heating fuel to make power first as backup fast charging dc to the batteries makes it most efficient. Solar panels are so cheap, sunelec, etc, that one can make power around $06/kwhr which no utility can beat. My home last yr was crushed by a tree and just built it's 150sq' replacement, I like tiny houses, for only $1200 because I'm cheap and on SSI. Most interesting is even thought so handicapped I can't lift the sheets of plywood I ended up doing all but 3 hrs myself, mostly help standing the walls and moving stuff I couldn't. Even though I have grid I'm going solar the low cost route using my lightweight EV's as part of it, 48 and 72vdc packs. It'll be a 24vdc system because those voltage panels cost the least with the house running on 12vdc for lights, most electronics, fans, cooking, etc by selecting the higher charged pack half. I've found cooking needs much less power than thought. I have 2 roadpro insulated old style lunchbox looking hot pans, lids that get very hot on just 11 amps. AS do other RV. boat 12vdc pots, pans, etc. At least for 1 or 2 people. And 2 car headlights can make a great small oven. And lead is still cheap as I get 50% off at local auto parts stores as most will bargain now. And 4-20 batteries is a big order so they will discount deeply. My lightweight EVs, EV trike pickup, can be charged directly by switching the panels to 48vdc nom which works because it is home most of the time, only uses 60wthrs/mile and don't need to drive much as work at home. So including my home A/C in Fla it'll only take 1kw of panels to power all this shows the low end of the scale. All up the tiny house and solar will cost under $2500 so no one can say they can't afford either if they can afford rent, they can. Jerry Dycus.
