<div>I was just about to ask exactly the same question here on
the Wrenches list. The BZ controllers seem to fill an amperage
niche vs price point that we need here for small MPPT 12v -
suresine systems deployable by helicopter, canoe etc. We don't
need UL listing for these systems. </div>
<div style="">I'd love to hear reports on these controllers from
other Wrenches before I buy any of them and haul them out into
the bush.</div>

<p class="MsoNormal">Hello wrenches,</p>
<p class="MsoNormal"> </p>
<p class="MsoNormal">Anyone have any experience with
BZ Products charge controllers? Kind of thin website
(<a moz-do-not-send="true" href="http://bzproducts.net/" target="_blank">http://bzproducts.net/</a>)
but it seems like a pretty slick way to be able to
use the ubiquitous 60 cell panels in small systems,
if the controllers are quality.</p>
<p class="MsoNormal"> </p>
<p class="MsoNormal">Any thoughts appreciated.</p>
