I originally installed a two string, 48V bank about 5 years ago (using quick coat). the customer decided he wanted to pour a concrete pad under the batteries, so he moved them, and later reinstalled them all by himself. I got the call this fall that his system was down. got on site and found no voltage at the inverter. both strings went open -- one fairly dramatically. individual battery voltage check ok. so we cleaned things up, redressed every thing, and reassembled. all systems go. the only thing I could figure was the battery goo dried out (solidified some) and prevented a good electrical contact when Ken reassembled them.. I just make sure the connections are squeaky clean now. db<br></div><div><br></div><div><br>Dan Brown<br>President<br>Foxfire Energy Corp.<br>Renewable Energy Systems<br>(802)-483-2564<br>www.Foxfire-Energy.com<br>NABCEP #092907-44<br><br></div>

</style> <div class="Section1"> <div><span style="color: rgb(31, 73, 125);">Funny…Quick-Cote is what I referred to in my post Wednesday about this, that we got through AEE. I don’t ever recall it drying out, and we’re in a dry desert climate. Nor have I ever (unless it’s really dirty) cleaned it off and reapplied it, even when replacing batteries using the same previously-coated interconnects. That’s not to say you’re wrong, Dan, just to note how two Wrenches can draw different conclusions from similar experiences.<o:p></o:p></span></div> <div> <div><span style="font-size: 11pt; color: rgb(31, 73, 125);">Allan </span><span style="font-size: 10pt; font-family: "Tahoma","sans-serif";"><o:p></o:p></span></div> </div> <div><o:p> </o:p></div> <div> <div><span style="font-size: 10pt; font-family: "Verdana","sans-serif"; color: black;">Interstate battery sells a goo called quick coat. (By quick cable). seems to work pretty good. The only problem I've had with it is that it can dry out and get waxy so you need to be sure you clean it all off and reapply it if you need to interrupt the connections. (and don't forget to torque). db<o:p></o:p></span></div> </div> <div> <p class="MsoNormal" style="margin-bottom: 12pt;"><span style="font-size: 10pt; font-family: "Verdana","sans-serif"; color: black;"><br> Dan Brown<br> President<br> Foxfire Energy Corp.<br> Renewable Energy Systems<br> (802)-483-2564<br> www.Foxfire-Energy.com<br> NABCEP #092907-44<o:p></o:p></span></p> </div> <blockquote style="border-style: none none none solid; border-color: -moz-use-text-color -moz-use-text-color -moz-use-text-color blue; border-width: medium medium medium 1.5pt; padding: 0in 0in 0in 6pt; margin-left: 6pt; margin-top: 5pt; margin-bottom: 5pt;" id="replyBlockquote"> <div> <p class="MsoNormal" style="margin-bottom: 12pt;"><span style="font-size: 10pt; font-family: "Verdana","sans-serif"; color: black;">-------- Original Message --------<br> <br> Everybody has their favorite goo. Ours is Burndy Penetrox, a thick gray paste that we apply with an old toothbrush and work it on good so it's not too thick but everything's well covered. It's much thicker than Vaseline so it never melts or runs. One bottle lasts us a year or two. Terminals that are many years old look like the day they were applied.<br> <br> Bruce Erickson<br> Mendocino Solar Service<br> <br> <o:p></o:p></span></p> </div> </blockquote> </div> <hr>_______________________________________________<br>
