I assume most people on the EV discussion list have subscribed to CHARGED
magazine? It is free to EV insiders (comes every 2 months) and is a great
technical mag (no circuits of course), but lots of fluff about all the new

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

A dead 12 volt battery is the problem when you have your control

Mike is correct - a single old inefficient panel can draw a sustained arc

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

I don't think that is how in rush current limiters work. I use them to protect

I've never tried this, but I've heard (probably here on the EVDL) of using a
PWM DC motor controller for this purpose. You'd probably need an inductor
in series with its output to simulate motor inductance, so the controller's
current limiting circuit would have time to do its job.

Aren't most all vehicle electrical items switched electronically these days?

Jan,
For someone new to electric vehicles, and for a majority of conversions, a 12
volt accessory battery is the simple means to power accessories. The car you
are converting was built that way, many 12 volt accessories exist and are
available at a reasonable cost, no need to make a lot of chan

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

That's right. The KISS solution is a 12v accessory battery. Even Tesla
is using a 12v lead-acid accessory battery.

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 strin

You generally pay by the watt. Similar price to switch 12v at 100a, or
