PV and home automation

    Anyone have any experience with grid-tied PV system working in conjunction
    with home automation, in particular power-line carrier types like X-10 and
    UPB?

    I'm wondering what effect the inverter may have on the powerline signals. I
    plan to tie the pv on the utility side of a whole-house signal blocker/phase
    coupler, but am wondering if that filtering is sufficient to give clean
    enough signaling inside the house.

    I figure someone here must have already incorporated both PV and PLC systems
    (or tried to!) and hopefully will be willing to pass on whatever they
    learned from the experience. I'm starting from scratch replacing a house
    that burned, so at this point can be pretty flexible as to which way I go
    with automation control.

    Thanks

    Best regards,
    Dennis

    My guess is that as a grid tied inverter has to give a very good quality
    sine wave output, X10 will work just fine.

  3. Some devices will operate with signals in the 50mv range (radio shack) and
    most operate in the 100mv range. This operates on a carrier frequency to
    send data (I think it is digital). Systems like this have been around since
    the early 80's from radioshack and some are X10 compatable.

    I run an off grid home on a msw inverter. I'd be happy to test some x-10
    equipment for anyone.

    I've got a Trace SW4048 grid-tied system, and lots of X-10 devices. I
    found that my X-10 stuff works more reliably now, on the inverter, than
    they did when they were running directly off the grid.

    X10 signals are transmitted just after the voltage waveform zero crossing.
    This is in order to avoid conflicts with SCR and Triac peak waveform
    switching spikes from load type devices such as lamp dimmers.

    Wrong yet again, GymyBobbit. They send the 120khz waveform PRECISELY at 0
    degrees...and then again twice later in the 180 degrees of the half wave.




    ============================================

    The X10 protocol apparently sends signals at the zero crossing of the AC
    line voltage and then at 60 degrees and at 120 degrees after that (in other
    words, three times every half cycle corresponding to the zero crossing of
    the other two phases). This is designed to make X10 compatible with three
    phase power situations.

    Voltage does not indicate state of charge well.

    At 11.6 volts a 12v battery is about 50-70% charged still.

    Polish solar panels are what americans called "flashlights"

    Propane will disapate and freeze when it evaporates.

    Gasoline is not nearly as volatile as hydrogen.

    Many people have browsers that economize the download

    Just another threading error creating confusion

    Try to stay on topic and on thread too bean brain.

    Perhaps try Outlook Express or another browser that knows how to thread
    posts.

    Bottom posting was the was in the 70s and 80s before threading browsers were
    available cheap like OE

    Another Forte Agent person that doesn't understand threading.

    You use Mozzilla and haven't learned to thread.

    Try Outlook Express so you can understand threading maybe.

    I have been noticing many threading errors everywhere on Usenet lately.

    People with OE don't seem to have the petty problems with subject
    lines changing, intermingled posts and downloading binary files with mixed
    posts, random pieces and many other problems all the nonOE people have.

    Bottom posting has been obsoletely by threading browsers.

    Let's say youre solar cell was trying to put out
    14.3 volts DC and you stuck a 10 ohm meter in series with a charged 13.8
    volt DC battery.

    I think outside opinions are worth much more than sales hype from the
    company that made the product.
    ## Referring to *factory* charging specifications for the batteries they
    make ##

    This is power grid induction through capacitive proximity

    You can get fooled with another ground in the house finding it's way back to
    the transformer neutral.

    A thought I have is rain water from a roof on a three story home through a
    micro-turbine.

    Setback thermostats only work efficiently for small differentials, dependant
    on the time duration.

    Breakers are good for one time usage of one fault and then they need to be
    replaced for any warrantied usage.

    If the breaker interupts a fault, it should be replaced.No warranty will
    honoured after that.

    I don't have a link at this time

    There are no hydrogen molecules in water and the oxygen in water isn't
    flammable either.

    Water is inert and contains no energy to be used. Get some basic chemistry
    first.

    Quite simply put, for some of the boneheads here.

    NiCads and NiMh batterries are designed to take a current charge forever.

    Oh yeah, I can charge a battery and use it six months later fully charged.
    The nicads will be cooked because you keep them on charge, just in case you
    need them but when you remember them six months later they are cooked and
    won't last 5 minutes in the camera.

    It takes a complete idiot to deny they can short out all by themselves.
    Three, loose in a bag can short themselves out.
    ## referring to AA batteries doing the physically impossible ##

    Did they have electricity back in 1994?

    I have been around so long with this stuff I believe I invented the diode in
    1941 but I am not familiar with the solar panel usage requirements of them.
    (no P & N substrate explanations please. I wrote the GE manual...LOL)

    NOTE: do not pass ground wires through metal holes or cable clamps with two
    screws on a metal surface.

    There is **NOT*** enough energy in a lightning bolt to power your house for
    more than an hour...if that. Do the math.
    The figures escape me but let's say it puts out a roughly MWatt of power for
    100 nanoseconds?
    100 x 10-9 x 1 x 106 / 3600 (sec/hr) = 0.0027 wH
    oooops.... Wouldn't light your home for a 1/2 second.
    OK..OK.. multiply the figures time 100 or 1000. Now it would light a 100W
    bulb for 1 second.

    The IEEE-232 standards were never followed or known by many.

    Fossil fuels are still renewable and being cxreated as we speak.

    10 pounds per gallon Imperial. That gallon is totally unique to the

    The standard Imperial gallon the whole world used weighs 10 pounds exactly.

    The copper isn't worth more than 5 cents per pound. It is classed a mixed
    copper and nobody wants it.

    Hey moron! The copper is considered "mixed" copper and is worth about $0.02
    per pound, if he seperates it all.

    Just don't ever lose weight. Toxins are stored in your fat cells.

    Did you know, **NO***, I repeat ***NO*** death has ever been related to
    PCBs?

    Insulated square copper wires from a dry transformer are not 99% copper and
    take a lot of work to remove the insulation.

    I have tonnes of insulated copper wire if you want it. I think you could
    almost have for the picking it up. How many bins can you take per year

    50 lbs? We have it by the bin full. Mostly #6 to 650 MCM. I beleive you
    would have to leave a bin and then pick it up full later to compete with the
    current scrapper.

    Can't this tranformer be used by somebody to generate a second 120V from a
    single phase 120V inverter? It sounds pretty beefy.

    BTW: once you knock the wedge out of the coil form the laminations will be
    easier to get out. This keeps them from buzzing until the varnish and other
    impregnations go into it.

    All you guys have a bad Christmas or Jewish and didn't see Santa or something?

    Run each signal twisted with a ground for noise. RD twisted with gnd as a
    pair, TD twisted around ground as a pair etc... This means signal/logic
    ground not power ground or case ground, if they are different. Do not
    connect the other ends of the ground conductors.

    Tar pitch in a flourescent ballast does ***NOT*** contain PCBs and probably
    never did.

    I believe the warmest part of the lake is just below the ice. As the water
    frezes it rises to the top and joins the other ice formations.

    Gel cell won't cut it when it comes to putting out 100A or more. They cook
    in one spot and the rest of the electrolyte doesn't circulate fast enough.

    There is nothing standard about USanian measurements. They changed their
    sizes to avoid trading with the rest of the world. This worked for a few
    centuries but the rest of the world moved on to the metric system to avert
    the confusion the US caused.

    Ever put your ohmmeter (do I need to explain an ohmmeter also?) across a
    capacitor? It measures infinity after charging to the supply voltage because
    the electrolyte is an insulator.

    Electrolytes are not conductors of electricity in a capacitor.

    If the electrolyte conducted it would be a resistor.

    I doubt they are 4 farads. More likely 4 microfarads uf.

    A 50Hz transformer needs double the iron a 60Hz transformer needs for the
    same VA capacity.

    Does it test CTs with real current or just voltage?

    It doesn't really matter where the secondary current comes from, secondary
    exciting or primary current exciting, the voltage developed or excited
    across it will be about the same.
    ## talking about an OPEN circuit CT transformer ##

    High voltage spikes want to keep going at the end and this is where your
    saturating core transformer core is located behind the fuse.

    See a naturopathic doctor for the chemical imbalance.
    See a medical doctor for a some poison that will make her life shorter.

    Homeopathic remedies are very toxic substances and used because of their

    "grid tied" with or without a battery bank?

    If you do have a battery bank, try turning off your main grid breaker
    and try the X10 then.

    Knowing the shape of the SW output waveform, I'm very suprised if the
    X10 stuff works when powered by the inverter. But if you have no
    battery bank, that never happens.

    Gawd, you're so transparent. You also plonked me a while back , so you'd
    have NO way of knowing what I'm posting. I'd appreciate you not using my
    name in your juvenile revenge attacks.

    This stuff is really easy to stop. Merely stop posting your understanding of
    the world as FACT.

    I also see how you've managed to antagonize people in just about every group
    you go to. Did you ever consider, just ONCE, that perhaps it's YOU?


    That was a rhetorical question.
