  You're describing our "Home Run" cable and the connectors for the<br>
  AC Modules.<br>
  <br>
  Replacements are easy.  The inverter base stays on the PV.  The<br>
  cable is a part of that base.  You don't need to disconnect anything.<br>
  <br>
  Just remove four screws from the inverter (the "lid" of the
  enclosure<br>
  is actually the inverter heat sink), remove it (there's a five pin mating<br>
  connector inside the inverter .. the female half on the inverter, the<br>
  male half in the base) .. remove the inverter .. pop the new one in,<br>
  and replace the four screws.<br>
  <br>
  That's it.  No wiring to mess with.<br>

  cable to which you attach piercing taps that come attached on a drop from
  each AC module's inverter. I like not having to worry about connector
  spacing. I'm not sure how you handle replacements or removals, but I'm sure
  that's been addressed. I haven't used these modules yet, but I can see the

      David,<br>
      <br>
      Our inverters are a *true* AC Module, not just a micro-inverter that's
      been<br>
      attached to the PV frame or other structure.  They replace the
      junction box<br>
      on PV, and must be installed by a PV manufacturer, distributor, or OEM<br>
      that are certified to the appropriate UL Standards for that
      process.  Our<br>
      AC Modules are not designed for field/site installation to PV.<br>
      <br>
      The advantages to this: We're exempt from DC-side ground-fault and<br>
      arc-fault because all DC conductors are internal to our inverter, and are<br>
      all less than 80Vdc.<br>
      <br>
      Being mounted directly to the PV eliminates the j-box, diodes,
      high-voltage<br>
      DC conductors, and expensive DC connectors and their associated hassles.<br>
      This also reduces the product cost and decreases the system installation<br>
      time.  You're also assured of a perfect match of our inverter to the
      PV.<br>
      <br>
      For notes - our AC Module inverters are made in
 Fort Worth , Texas .<br>

        like to correct an error in Jim's statement below related to how we<br>
        at Exeltech handle warranty.<br>
        <br>
        If an AC Module inverter should fail, the entire module does not need
        to<br>
        be sent back for warranty -- just the inverter itself.  In our
        case, this<br>
        involves removing four small screws to separate the inverter from the<br>
        base.  The "lid" (or top of the enclosure) is the heat
        sink of the inverter.<br>
        The base stays attached to the PV.  There's no wiring
        involved.  It's all<br>
        internal, and you don't have to do anything except remove the old<br>
        inverter from the base and plug in the new one.<br>
        <br>
        Once you access the back of the PV, total time to effect the swap<br>
        is typically about 1 minute.<br>

         Bridge &

        inverters. One of the questions to ask with ACPV is who backs the
        warranty on the inverter. According to SolarBridge’s website, the
        module manufacturer warranty’s the combination. This is fine as long as
        the mfg stays afloat but in this time with such major players as Sharp
        and BP backing out, who do you turn to if your inverter has a problem?
        As Bill said Exeltech is in this too, and warranty’s their own, so is
        one step less removed. </span></font></p>

        <p><font color="#1f497d" face="Times New Roman" size="3"><span style="font-size:12.0pt;color:#1F497D;">One of the things we’ve gathered
        is that Enphase, with an installed base of something over a million, is
        having some problems with its first version, 190. Is that a problem
        inherent in the components chosen in its design or something as simple
        as insufficient potting? It is fairly low percentage,  but it also
        hasn’t been 25 years. And how does that balance with the installed base

        <p><font color="#1f497d" face="Times New Roman" size="3"><span style="font-size:12.0pt;color:#1F497D;">It seems that the temperature at
        which micros are required to live is the main advantage of remote
        string inverters. They can be down in the shade with free air moving
        around them.  On the other end of that trend are the ACPV which
        might have very little room between them and the module backing. There
        might be several practical actions like mounting the modules with the
        inverter on the down side so the air flow is cooler (a little like
        putting the pump or fan on the cool input side of a thermal collector),
        or spacing the array higher off the roof to allow more air flow.</span></font></p>

        Hi Nik,<br>
        <br>
        As of SPI 2012, Solar 
         Bridge advertized
        seven module manufacturers using their product.<br>
        <br>
        Remember Exeltech, manufacturer of exemplary sine wave inverters, is
        also a player in this ACPV market, undoubtedly other players, too.<br>
        <br>
        IMHO, ACPV is the route that the industry will _eventually_ follow. </span></font></p>
