Re: [EVDL] Off-grid solar house

   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

In the early days of switchmode PSU's it was common to use N.T.C. resistors for inrush current limiting, later on we went away from that. Look at PC power supplies from the '80s and '90s at least, they have a 1 Ohm, 5 W resistor in series (for a 230Vac PSU. The problem with an NTC is they stay

Re: [EVDL] 12v tales

Another reason is that you can reduce the capacity of your dc-dc converter. Running lights, A/C, windshield wipers, fans, brake pump, power steering, etc. all at once is a large current draw. But a single high current 12V battery can handle that and keep those devices powered for a long

Sanity check: The only reason to build off-grid is if the Power Company wants more than $15,000 to run the lines to your house. If you are near the lines, and for some reason insist on not connecting, then you will be wasting $2 of every $3 your solar investment on batteries and maintenance for
