I have used the BZ Products controllers for several years with excellent results. They are my go-to solution for small 12 and 24V systems. I mostly use the MPPT500 and 500HV units because they come with a conduit-ready enclosure. The HV version works well with 2-60 cell modules in series. They are definitely a bare bones unit, and the enclosure could do with some better graphics so that it doesn't look so homemade, but they work well, and I like supporting a small US-based business. <br>
Drawbacks are the lack of an EQ function and non-adjustable charge setpoints. (And the homemade look)<br>
So far I have only had one unit fail, which seemed to be due to a bad component as it basically failed immediately after hooking it up. BZ replaced it under warranty.<br>
I'd recommend them. It's a great way to use 60 cell modules for small systems and you can't beat the price for a MPPT unit.<br>

Hello wrenches,<br>
<br>
Anyone have any experience with BZ Products charge controllers? Kind of thin website (<a href="http://bzproducts.net">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.<br>
<br>
Any thoughts appreciated.<br>
<br>
Thanks,<br>
-Nathan<br>

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