    Shocking isn't it?

    Ok, yesterday i had my inverter going for a test run of the carpc. My friend noticed that she kept shocking herself everytime she got out of the car (like static charge shock not electrical). I don't remember anyone having this problem before (inverter is under passenger seat). Is the inverter transferring some current through the seat or what could be going on here?

    Does it still happen if you disconnect the inverter?

    Not exactly sure....we didn't take notice of the shocking til' last night which i had the inverter on. If i knew that then i would have already come to my conclusion.

    Its always better to go with dc-dc PSU why does one want to play with AC current in a car which goes through so much of bumps and speed....

    Check the car chasis with a tester the for charge !

    This isn't exactly abnormal for any car especially in the winter months. My wife's car will shock us EVERY time we get out of the car in winter- my solution is to not touch any metal when getting out if I can avoid it. I wouldn't worry to much about it unless someone get knocked on their a** by the shock.

    Kinda a rant here, but just because dc-dc is better for you does not mean that it is better period. DC-AC-DC is MUCH cheaper, and then allows you the ability to run ANY household device in the car. You pick any computer related product you might ever want to run in the car, and we'll compare who can get it working first. Say a wireless router, or a LCD screen, or perhaps a force feedback joystick? I can run it all off the inverter, what about your DC-DC supply? Sorry for the rant, I'm just tired of seeing everybody claim that DC-DC is the solution for every power/static/humm/distortion problem posted.

    Amen Jackso. I think a lot of the problems people experience with DC-AC-DC systems is due to improper shielding and ineffective grounding. As my install progresses I'm going to be adding another Alternator and grouding it out to the Car Battery & alternator, and also installing a copper grounding strip that will run the length of the car. This way I KNOW that grounding won't be an issue if problems arise.

    I agree with you friend you can not use a blow dryer with a dc-dc solution.

    My feel is AC 110 / 240v should be kept away from cars.

    Rest is upto.. you

    Agreed. Notice that the people defending inverters are usually the same people who can't get their systems working right in other threads.
