Larry,
Thanks for the info. I also have had good luck with Morningstar Tri
Star and Tri Star MPPT charge controllers. A few weeks ago I had a
bunch of failures in the same week (on both models). They sent me new
ones promptly, I went on vacation and now everything is fine...
Best,

Jason,
Not much to elaborate on. A single 200 watt Sanyo module, about 25'
of 8 gauge wire, lowest temperature 20 degrees. When the SunSaver
controllers fail, they cause a short circuit at the battery
terminals. Morningstar handled the warranty as they do all SunSaver
warranty's, quickly sending replacements with return postage for the
defective unit. We have had 4 SunSaver failures since November 1.
I sell 150+ charge controllers at our retail store each season (Nov.
~ Dec.), most of which are MPPT. Reliability is critical to me and I
pay very close attention to failures. Most of my customers are
mobile and not able to return to our store if a product fails. I
have tested and sold many MPPT models. The Phocos MPPT controller I
was evaluating failed and we have had our share of Outback and BZ
controller failures. Blue Sky Energy has had a few bad controllers
but compared to the volume of BSE products we sell (over 1100) they
have been the most reliable. I have not yet tested Steca, TriStar,
or Xantrex MPPT controllers.

Hi Larry,
I am curious about the failures you have had, could you elaborate?
Thanks,

single Sanyo module in small battery systems. Perhaps they just
can't handle the 50.9 Voc.
