Reversing Electric Meter Legally

  1. Hey. I read on a site that some states have a new law where you can make/buy
    your own solar generator, plug it into the wall, and deduct from your electric
    bill. Sounds a little too good to be true, espeically because you can do it up
    to 50KW. Any idea on the effectiveness? Also, will it interfere with or
    possibly damage other household appliences?

    Assuming you are inverting the DC to AC, most utility meters will not
    spin backwards more than one turn of the disk, so you could only
    deduct from the power you are currently using. You could plug this
    into say your dryer outlet and back feed the electrical panel .

    This would provide you the results they claim if the solar unit is
    capable of synchronizing with the AC line. This whole setup is likely
    to be illegal and dangerous because it can energize the utility lines
    when there is a power outage.

    Some utilities however will allow this if special arrangements are

    It's actually not a new law. In some states, since they made it illegal
    for anyone but the recognized power company to sell electricity, they
    also made it so that the same recognized power company MUST buy
    electricity back from any citizen who decides to generate it. But it's
    not as simple as you suggest.

    You MUST have a device called a line-locked inverter which makes sure
    your power is synced to the utility power, and it turns itself off if
    there's a power failure on the grid. You feed your power back through a
    second meter. The power company reads both meters. They charge you
    retail price for the power you take, and credit you wholesale price for
    the power you generate.
